[Thomas Broyer]

What kind of Cell is this? Can you show part of the code that sets up the 
table?
Did you set KeyboardSelectionPolicy to DISABLED?

Keyboard Accessibility: while tabbing the first element in celltable gets focus

[nidhizener]

I am working on adding keyboard accessibility to my application. When 
tabbing from on e widget to another if there is a celltable, it is included 
in the tabbing sequence. The cell table in not editable, still it gets into 
tabbing sequence. How do I remove the cell table from tabbing sequence? Is 
this known issue? Wondering if there are any work arounds? Any help will be 
appreciated.

Re: Populating CellTable using ListDataProvider?

[Slava Imeshev]

Craig, 

Yep.  makes sense for "show-and-forget" use pattern.

The challenge with  is that things become complicated when there is 
a need to receive and act on events on row selection/de-section, 
pagination, getting the entire data object out of the row etc. I tried that 
but discovered that I'm reinventing CellTable.

At any rate, the only snag I had with CellTable is unexpected behavior with 
pageSize set to 0. It would be great to have better Javadoc for that, or 
throwing IllegalArgumentException for 0 size.

Re: Populating CellTable using ListDataProvider?

[Craig Mitchell]

Just to clarify my comment.  I find it easier to use pure HTML + CSS then 
GWT's built in CellTable etc.

Eg:

@UiField TableElement myTable;
TableRowElement row = myTable.insertRow(...);
...

Then you can use all the fancy CSS styles, that others have written to make 
tables look pretty.  No need to mangle them into what GWT wants.

Adding GWT widgets into the table is a little annoying that you need to 
call onAttach to get their events to work, but that's a minor inconvience.

Anyhow, I wasn't suggesting writing any JavaScript.  :)

Also not saying don't use CellTable.  Maybe you have a massive amount of 
data, and all the fancy databinding will save you time in the long run.

Re: Populating CellTable using ListDataProvider?

[Slava Imeshev]

Hi Tomas,

First, pls. let me thank you and the team for the amazing work on GWT.

As for the documentation, I'd say it's lacking an example for importing 
custom widgets  because the way some of use read the XML. Personally I just 
automatically skip over the xmls section because it contains "standard" GWT 
namespaces. 

I think the docs would benefit from explicitly stating

 "To import your own widget com.example.gwt.client.SampeTextField, use the 
xmlns to add a package with your own packages and then use the prefix in 
the body of the template. For example:

Re: Populating CellTable using ListDataProvider?

[Thomas Broyer]

Is this 
<http://www.gwtproject.org/doc/latest/DevGuideUiBinder.html#Hello_Widget_World> 
not enough? Buried too deep? Lacking examples and/or a step-by-step?

In order to use a set of widgets in a ui.xml template file, you need to tie 
their package to an XML namespace prefix. That’s what’s happening in this 
attribute of the 
root  element: xmlns:g='urn:import:com.google.gwt.user.client.ui'. 
This says that every class in the com.google.gwt.user.client.ui package can 
be used as an element with prefix g and a tag name matching its Java class 
name, like .

See how the g:ListBox element has a visibleItemCount='1' attribute? That 
becomes a call to ListBox#setVisibleItemCount(int) 
<http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/ui/ListBox.html#setVisibleItemCount-int->.
 
Every one of the widget’s methods that follow JavaBean-style conventions 
for setting a property can be used this way.

Hey, hey, hey,

I'm one of us Javascript-deaf. With GWT I'm back to my a screen-a-day in 
pure Java. Just loving it.

Still, would GWT team be accepting of some PRs to update Javadocs? Took me 
a day of Googling to figure out how to make use of custom widgets in UI 
Binder templates.

Re: Populating CellTable using ListDataProvider?

[Craig Mitchell]

GWT does many great things.  Implementation of lists and tables wasn't one 
of them (IMHO).

If GWT 3 ever comes out.  It will be great to have separation of this stuff.

However, to answer your question, yes, it would make sense, I just don't 
know what the likelihood of a 2.9.1 release is.

Re: Populating CellTable using ListDataProvider?

[Slava Imeshev]

Folks, 

Just following up on what turned to be my own blunder. Using 
ListDataProvider doesn't work when the CellTable is created using pageSize 
= 0. 

super(0, resources, keyProvider);

It still works when using setRowCount(); setRowData();.

So I fixed it for the time being by setting a meaningfully large pageSize.

Here is the question: would it make sense to add a bit more to the Javadoc 
for pageSize. Or maybe checking for 0 and throwing IllegalArgumentException?

Populating CellTable using ListDataProvider?

[Slava Imeshev]

So, I'm following basic examples, and I just cannot get it to work. The 
populate() method below using ListDataProvider leaves the table empty. 
populateWorking() works. Any hints?

public class GapAnalysisListTable extends CellTable {

public GapAnalysisListTable() {

// Create a data provider.
dataProvider = new ListDataProvider<>(GapAnalysisVO::getId);

// Connect the table to the data provider.
dataProvider.addDataDisplay(this);
}

public void populate(final GapAnalysisVO[] gapAnalysisVOList) {

final List list = dataProvider.getList();
list.addAll(Arrays.asList(gapAnalysisVOList));
dataProvider.refresh();
}

public void populateWorks(final GapAnalysisVO[] gapAnalysisVOList) {

setRowCount(gapAnalysisVOList.length);
setRowData(Arrays.asList(gapAnalysisVOList));
}
}

Re: Filters for cellTable

[mabruneau]

Hi,

For my project, I decided to go with a JSNI wrapper around this JS control:
- http://w2ui.com/web/demo/grid

It works well and has lots of settings. I'm not sure of your requirements 
but for me, it worked much better than the core UI library of GWT.

Good luck.

Filters for cellTable

[nanditha212]

HI All,
I have a cellTable that displays date(as string)  in one column and few other 
details in other column.

Is there any way to have filter for this date column. Like date range. 
On selecting the particular date range. The table should be displayed.

Anyone got some information on this? Please.
Thanks.

Re: SuggestBox in a CellTable

[Nanditha Nandu]

Hi Craig,

I'm trying to place the SuggestBox widget inside CellTable.
Created the custom class "SuggestBoxTextInputCell" which extends the 
TextInputCell.


And changed the browserEvent as following:

*public* *void* onBrowserEvent(Context context, Element parent, String value
,

NativeEvent event, ValueUpdater valueUpdater) {

*super*.onBrowserEvent(context, parent, value, event, valueUpdater);

// Ignore events that don't target the input.

InputElement input = getInputElement(parent);

String eventType = event.getType();

*if* (BrowserEvents.*FOCUS*.equals(eventType)) {

TextBox textBox = *new* MyTextBox(input);

suggestBox = *new* MySuggestBox(suggestBox.getSuggestOracle(), textBox);

suggestBox.onAttach();

} 

Element *target* = event.getEventTarget().cast();

}


But I want to pass my own suggestionText. 

Hence the created a constructor:

*public* SuggestBoxTextInputCell(MultiWordSuggestOracle suggestions) {

*this*(suggestions, *new* TextBox());

}

*public* SuggestBoxTextInputCell(MultiWordSuggestOracle suggestions,

ValueBoxBase box) {

//this(suggestions, box);

}

After this I'm stuck.

And want to call SuggestBoxTextInputCell(Suggestions) in CellTable.

It would help knowing what the problem is, as we don't know what your 
custom SuggestBox is.

Maybe look into 
http://samples.gwtproject.org/samples/Showcase/Showcase.html#!CwCustomDataGrid 
and 
look how EditTextCell works, and then make a EditSuggestBox.

Re: how to create an anchor column in a celltable

[hy]

Create a class that renders anchor like below:

public class CustomAnchorCell
extends ClickableTextCell {

private String itsHref = "";
private boolean isEnabled = true;

public CustomAnchorCell(String inHref) {
super();
itsHref = inHref;
}

public CustomAnchorCell() {
super();
itsHref = "";
}

public CustomAnchorCell(String inHref, boolean inEnabled) {
this(inHref);
isEnabled = inEnabled;
}

@Override
protected void render(Context context, SafeHtml value, SafeHtmlBuilder sb) {
if (value != null) {
String theElementStart = "";
String theElementEnd = "";
if (isEnabled) {
theElementStart = "")
.append(value)
.appendHtmlConstant(theElementEnd);
}
}

public void setHref(String inHref) {
itsHref = inHref;
}

public void setEnabled(boolean inEnabled) {
isEnabled = inEnabled;
}

public void setClassName(String inClassName) {
itsClassName = inClassName;
}
}



Use it like this:

Column theReport = new Column< Report, String>(new 
CustomAnchorCell()) {
@Override
public String getValue(Report object) {
return "Hello New Tab";
}

@Override
public void render(Cell.Context context, Report object, SafeHtmlBuilder sb) 
{
CustomAnchorCell theCustomAnchorCell = (CustomAnchorCell) getCell();
theCustomAnchorCell.setHref("_your new tab url_");
theCustomAnchorCell.setClassName(*"_your custom css class name_"*);

super.render(context, object, sb);
}
};

Re: how to create an anchor column in a celltable

[Thomas Broyer]

If you want to display text as-is (e.g. not a link), then you can use a 
ClickableTextCell (see it live, with source code, 
in 
http://samples.gwtproject.org/samples/Showcase/Showcase.html#!CwCellSampler), 
the FieldUpdater will be called when the cell is clicked.
Alternatively, you could use a TextCell with a custom SafeHtmlRenderer that 
would wrap the URL in a link (easiest would probably be to implement this 
using a SafeHtmlTemplates: pass the URL as input –you'll want to pass it as 
a SafeUri, constructed using UriUtils.fromString()–, use it to construct 
something like {0})

Re: how to create an anchor column in a celltable

[Josselin Bardet]

Hi,

You can use a custom cell to do what you want.
You can look at the ButtonCell class for exemple

The render() method is called for each row of the cell table, you can make
your  link there

@see com.google.gwt.cell.client.ButtonCell

how to create an anchor column in a celltable

[Ousti Driss]

Hey everyone,

I'm writing the code of a simple web app using gwt, I have a Celltable all 
its columns are String type,
one of the columns is a url column , I want to make this column clickable, 
which means once you click on a cell
of this column, you are redicted to the url shown, is that possible?
i tried to add an anchor column to the table, but I got error messages 
while defining this column when I call the getValue method, the type of 
return should be a string!!
Is there a way to do such a thing?

Thank you :)

GWT Celltable Issues

[P.Pon rani]

Hi,

I am facing celltable alignment issues in IE9. Columns fall down and 
aligned in a single block.

Is there any solution for the same.

Re: CellTable Page Size Optimization

[Jens]

Can't you just read the height of the table and calculate row count based 
on that height?

If you need notifications that a desktop user has made his browser as small 
as a mobile screen you can use media query events (use JSNI or JsInterop to 
make them available to your app).

CellTable Page Size Optimization

[Björn Rudzewitz]

Dear GWT Users,

I'm developing a GWT application that users access from devices with highly 
variable screen sizes and resolutions, such as mobile phones, desktops, 
tablet pcs, etc. In the application I use a CellTable to dispay data to the 
clients.

So far I couldn't find a way in which I can set the CellTable page size 
dynamically, i.e. always show the optimal number of rows per CellTable page 
such that is makes use of the given screen size. Did anyone of you face a 
similar problem or has suggestions how to tackle this ?

Best regards,
Bjoern

Re: GWT CELLTABLE How to restore old value in cell if validation fails

[Ved Ratna Mehra]

Its way too late but still and I think you must have already done this... 
Below would redraw only a single row.
dataGrid.redrawRow( rowIndexReceivedInUpdateMethod );

Help modifying celltable styles with gss

[Raymond Hawkins]

I'm in the process of updating to GWT 2.8, and I have the following code 
from 2.7:
public interface DataGridResource extends DataGrid.Resources {
  public interface Style2 extends Style {}

  @Source({DataGrid.Style.DEFAULT_CSS, "MaterialDataGrid.css"})
  Style2 dataGridStyle();
}

Following the instructions on 
http://www.gwtproject.org/articles/gss_migration.html, I'm trying to switch 
to using all gss. however, when I try to change MaterialDataGrid.css 
to MaterialDataGrid.gss, I get the following error: "[ERROR] Only either 
css files or gss files are supported on one interface".

I assume this is because "You cannot mix css and gss on the same method 
(@Source annotation)." and DataGrid.Style.DEFAULT_CSS points 
to com/google/gwt/user/cellview/client/DataGrid.css. 

If I manually use "com/google/gwt/user/cellview/client/DataGrid.gss", it 
works fine, but there doesn't appear to be a constant for the gss path. Am 
I missing anything here, or should I just either use the full path in my 
code or replace ".css" with ".gss" on DataGrid.Style.DEFAULT_CSS?

Thank you!

Re: Refresh of CellTable via data transmitted via WebSocket delayed

[Kay Pac]

Thanks very much Thomas - that was it. I checked the gwt-websocket, and it 
is indeed using $entry, while gwt-stomp is not. I altered the code and the 
problem seems to be resolved. Whew! So happy to have found this solution.

That hints at the callback that calls the setRowData and redraw not being 
wrapped in $entry().
CellTable defers its DOM update using Scheduler.scheduleFinally(), and 
"finally commands" (and "entry commands") are processed by $entry().
So, your callback schedules a finally task, but because it's not in 
$entry() it's not called "at the end of the event loop" as it's expected 
to; it's actually called at the end of the next event loop that uses 
$entry(), which is the case for almost anything that GWT does: event 
handlers, timers, etc.
So: make sure your WebSocket's callback is wrapped in $entry() (this also 
takes care of the GWT.UncaughtExceptionHandler btw)

Refresh of CellTable via data transmitted via WebSocket delayed

[Kay Pac]

I have a somewhat complex problem related to a CellTable that updates based 
on messages received over a WebSocket connection. The problem is as 
follows: The table does not update in real-time, even though "setRowData" 
and redraw* are called in real-time. There is a delay in the row appearing 
in the CellTable, or rather in the DOM as a table row. I realize that 
redraw does not actually redraw but sets a flag via 
HasDataPresenter.redraw, which checked elsewhere. It is often the case that 
mouse movement causes the row to appear - and I have been able to reproduce 
this behavior. When I put in a timer firing every 300 milliseconds, its 
execution also causes the row to appear.

It is flummoxing because the problem did not occur until I switched from a 
prototype implementation of basic websockets to a prototype implementation 
of STOMP-wrapped websockets (stomp being a MOM-supported protocol for 
supported messaging from "simple clients"). However, in both cases, there 
is no difference as to when the data is delivered via setData and redraw is 
called, so the change should not affect how or when the cellTable gets 
updated.

I am considering eliminating the use of CellTable and have a simpler DOM 
manipulation, but I'd prefer to determine what I am doing that is causing 
this problem, whether it is misuse of CellTable API or inappropriate 
expectations of CellTable behavior. I can't really post any code because it 
is all integrated, and I can kind of work around it.

Does anyone have any ideas how to approach this problem or where I might 
begin to look for a solution?

Sincerely,
Kay

Re: selenium and waiting for CellTable to load

I was thinking about this a bit, and I could probably use a hidden form

selenium and waiting for CellTable to load

[Kay Pac]

Does anyone have code for interacting with celltables in selenim tests?

I have a selenium test and a CellTable that is filled with the results of 
an RPC call. The table displays a "loading" image until the rows are 
populated, and I need to wait for the "loaded" condition in my selenium 
test code. I notice that in the element tree there are two TBODY elements, 
a second one which is styled "display: none" when the table is loaded - 
this contains the loading image.

I am using an xpath expression to find the second TBODY: 
"//*[@id='gwt-debug-gameDetailsTable']/tbody[2]"
Here is the code I am using right now. Basically, if the table has already 
loaded prior to looking for the TBODY, everything is okay - isDIsplayed is 
false. But if it isn't, neither of these ExpectedConditions work, even 
though the first one only checks to see that it isn't displayed anymore. I 
am using HTMLUnit version 22 and selenium 2.53.1.

WebElement tbody2 = driver.findElement(By.xpath("//*[@id='" + 
GWTID_GAMEDETAILSTABLE + "']/tbody[2]"));
if(tbody2.isDisplayed())
{
try {
logger.info("waiting for games table to load...");
Boolean until = (new WebDriverWait(driver, 10)).until(new 
ExpectedCondition() {
@Nullable
@Override
public Boolean apply(@Nullable WebDriver input) {
return tbody2.isDisplayed() == false;
}
});
//Boolean until = (new WebDriverWait(driver, 
10)).until(ExpectedConditions.invisibilityOfElementLocated(By.xpath("//*[@id='" 
+ GWTID_GAMEDETAILSTABLE + "']/tbody[2]")));
logger.info("until = {}", until);
} catch(Exception ex)
{
logger.warn("{}", ex);
}
} else {
logger.info("no need to wait for games table to load, 'loading' 
tbody is hidden");
}

Re: Updating CellTable row style

[Gilberto]

Inspect the row style at the browser developer tools to see which is 
preventing your classes to be applied.

Note that some styles can't be applied at row level, but only at cell 
level. I guess the border is one of those styles.

Re: Updating CellTable row style

[mohit]

Thanks for the reply Jens!

I tried adding  

mappings.getRowElement(event.getValue().getExecutionOrder()).getStyle().
setBorderStyle(BorderStyle.SOLID);

 But it didn't work :(


mappings.getRowElement(event.getValue().getExecutionOrder() ).getStyle().
setBackgroundColor("Red");

did change the background colour of rows, though.


I don't understand why one style gets applied and other doesn't.

I guess your border-style is still set to "none" (the default value) 
because you have not set any. You need to set it to "solid" for example.

Updating CellTable row style

[mohit]

Hi,

I am trying to update a row style for on mouse hover.

mappings.addCellPreviewHandler(new Handler() {

  @Override 
  public void onCellPreview(CellPreviewEvent event
) { 
if (BrowserEvents.MOUSEOVER.equals(event.getNativeEvent().getType
())) { 
   mappings.getRowElement(event.getValue().getExecutionOrder()).
getStyle().setBorderColor("Red"); 
  } 
});




Any idea why 
mappings.getRowElement(event.getValue().getExecutionOrder()).getStyle().
setBorderColor("Red"); 

has no effect?


Thanks

Re: DataGrid/CellTable with several tbody elements - frustation on trying to implement

[Gilberto]

I don't agree 100% with that, at least not in GWT. The framework should 
provide a "good enough" default implementation that covers most of the user 
cases, but not forbid the developer from extending it - I'm not talking 
about making everything public, but making everything extensible. The 
developer who is extending it is (or should be) aware he is modified 
something internal of the framework, that could change or break in future 
versions.

As I said, in pure Java, making a field or method private doesn't prevent 
you from calling it outside, by using reflection. So that kind of 
consideration (making everything as closed as possible) on a framework is 
annoying but not a show-stopper. You still can extend it when you know what 
are you doing. In GWT, even if you know what are you doing, and even if 
what you are trying to do is supported by the specs, you just can't.

And as a side note, since the 2.X version is supposed to not involve 
anymore after 2.8, maintaining everything as closed as possible because "it 
could break in the future" doesn't apply anymore.

Because it is generally a good practice to start as closed as possible and 
then open up APIs you feel comfortable with. As a library / toolkit / SDK 
you can not blindly make everything public because then you can never 
refactor that API as it would break lots of people who became dependent on 
these public APIs in the mean time.

But you can always bring up specific cases on the gwt-contrib mailing list 
so it can be discussed and maybe its fine to open up the API a bit here and 
there.

DataGrid/CellTable with several tbody elements - frustation on trying to implement

[Gilberto]

Hi there,

In my app I need to create a table with several sections, by using several 
tbody elements. For those how are wondering, yes, that's supported by the 
W3C spec: a table can have multiple tbody elements (see this question at 
StackOverflow 
<http://stackoverflow.com/questions/3076708/can-we-have-multiple-tbody-in-same-table>
 
for details).

I really need several tbody elements because the data structure and styling 
needed for each section cannot be achieved by just adding more table rows, 
or "header rows".

That being said, I started my research trying to find a way to do that with 
DataGrid/CellTable on GWT.

And then I found this thread:

https://groups.google.com/forum/#!topic/google-web-toolkit/6VxudGY11OA

... which states that:


[...] If you really need/want several tbodies, you'll have to fork the 
> whole thing


and

[...] If I were you, I'd first ask myself whether I really need those 
> multiple tbodies…


Well, in my opinion the framework is not supposed to judge if you need 
something or not, if what you want is supported by the specs. Anyway, the 
"you'll have to fork the whole thing" got me puzzled... How hard it would 
be to fork it?

First step is to create a custom CellTableBuilder. And by that I mean a 
class that implements CellTableBuilder directly, since we cannot use the 
DefaultCellTableBuilder or even the AbstractCellTableBuilder, because the 
"HtmlTableSectionBuilder tbody" object I need to access is private on 
AbstractCellTableBuilder. So I created a CustomCellTableBuilder with most 
code copied from AbstractCellTableBuilder and DefaultCellTableBuilder.

Ugly, but now I have access to the HtmlTableSectionBuilder object. Next 
step is to change it to allow multiple tbody elements.

And now the things started to be a real mess. The HtmlElementBuilderBase, 
which is the parent class of HtmlTableSectionBuilder, doesn't accept 
multiple top level tags. You are forced to start a tag and put stuff into 
it. And it gets worse: if you try to extend the HtmlElementBuilderBase to 
create your own builder, you just can't... because the constructor requires 
a HtmlBuilderImpl oject, which is only visible at package level 
(com.google.gwt.dom.builder.shared) !

And then I figured out what the "you'll have to fork the whole thing" 
means: I'd have to really fork the whole thing.

It's not the first time I stumble on package scoped classes or private 
fields/methods that forbids you to create a custom behaviour (even if that 
behaviour is supported by the specs). So I came with some questions:

Why GWT is designed that way, so hard to extend? Is that a reflection of a 
desperate need for contributors to the project, by having to "fork the 
whole thing"? Or is it to force the developers to use paid frameworks built 
on top of GWT?
Why package-scoped classes?
Why private fields on classes that are supposed to be extended?

In pure Java, such bad design for extension points can be treated with 
reflection. Not beautiful, not best performance, but it works. In GWT 
that's not an option, so we are left to "fork the whole thing".

I really hope that future versions of GWT have a better approach to 
extension points. The framework shouldn't forbid the developer from making 
his own choices.

CellTable equivalent

[Juan Pablo Gardella]

Hi devs,

As GWT 3.0 will remove widgets, someone know if exists a CellTable
equivalence in JS libraries? CellTable and Datagrid are awesome components.

CellTable loses text selection on update.

[jonbbbb]

I have a CellTable with some text cells.

I have a AsyncDataProvider and inside there I have a timer that runs every 
second.

But when I call updateRowData(0, list) every second it replaces the text in 
the CellTable.

If you have selected the text with the mouse it removes the text selection. 
If you move the 
mouse while keeping the mouse button pressed it creates an anoying flashing 
effect on the
selection.

Maybe this is the expected behaviour. But I have seen some other javascript 
stuff that is not
GWT that is able to update the text in a table without doing anything with 
the text selection.
The text changes while being inside the text selection. That is what I want.

So is there anything I can do to not have the selection disappear?

This is the html it produces for a cell: 

description http://google.com


The only work around I can think of is to not allow text selection with CSS 
to avoid this altogether.

Thanks,
Jay.

Re: How to insert Image into Column Header of CellTable (GWT)?

Better actually use a Header with an ImageCell (or ImageRessourceCell) possibly

Okay, I tried that and the data still doesn't appear.  However, I resizing 
the browser window, even with the 100% height, does cause the data to 
appear.  Calling the DataGrid's onResize() method, even in a 
ScheduledCommand from the container's onLoad() method, does not cause the 
data to be displayed.

Where can I report this as a bug?

Thanks again.

Re: GWT DataGrid does not display, CellTable does

[jaga]

I'd try placing each widget in its own container and showing hiding the 
containers rather than the tables.  If you use a layoutpanel as a container for 
each container then you can call LayoutPanel.setWidgetVisible().

Don't do that. ProvidesResize panels do set the size of their children.

Possibly related to https://github.com/gwtproject/gwt/issues/4694 (or

Try calling forceLayout() on the DockLayoutPanel when you switch to it in 
the DeckLayoutPanel.

IIRC, the "center" area must always be added last. Calling addSouth() 
before add() might be enough to fix the problem (it's been a while since I 
last manipulated layout panels)

This is (probably) because the widget is given explicit dimensions by the 
SimpleLayoutPanel (through the ProvidesResize/RequiresResize chain up to 
the RootLayoutPanel).

 I'll give it a try, but that's not really a robust approach.  GWT should 
be able to calculate the area it needs.  Setting explicit sizes seems error 
prone and inelegant.

GWT DataGrid does not display, CellTable does

My application consists of a SplitLayoutPanel that has a StackLayoutPanel 
with two menu selections on the left and a DeckLayoutPanel on the right. 
 The DeckLayoutPanel has two subpanels, one a SimpleLayoutPanel containing 
a Label and one a DockLayoutPanel containing a Label and another 
SimpleLayoutPanel.  The last SimpleLayoutPanel contains a DataGrid.

  |   + Label
  |
  + DockLayoutPanel (BudgetPanel)
  |
  + Label
  |
  + SimpleLayoutPanel (LedgerPanel)
  |
  + DataGrid

All subpanels have their height and width set to 100% by their containing 
panels.

The code is all available here: 
 https://github.com/patrickmay/data-grid-issue/tree/master/TestUI

*Expected Behavior*

The expected behavior is that clicking on the "Budget" menu item in the 
StackLayoutPanel will show the BudgetPanel, including the LedgerPanel's 
DataGrid.


*Observed Behavior*

When the "Budget" menu item is clicked, the DockLayoutPanel is displayed, 
with its header Label, the DataGrid column headers are displayed, but the 
DataGrid rows do not appear.

When a Label is added to the south area of the DockLayoutPanel, the 
application compiles but nothing is displayed, not even the top level 
StackLayoutPanel.

When the DataGrid is replaced with a CellTable, the data is displayed 
(although the height of each row is much more than necessary to hold the 
data).


*Questions*

What needs to be done to get the DataGrid to display as expected?

How can the rows be styled to have a smaller height?

Celltable w/SelectionModel not firing onSelectionChange event

[Matthew McLarty]

I have a CellTable that doesn't seem to want to follow my defined 
SelectionModel. I know I must be missing something dumb, does anyone see 
what I've done wrong here?

public class QuoteTable extends CellTable {
Column editColumn;
Column quoteColumn;
Column referenceColumn;
Column dateColumn;
Column contactColumn;
Column summaryColumn;
ListHandler columnSortHandler;
QuoteSearchSnapshot quoteSearchSnapShot;

public final static String QUOTE = "Quote#";
public final static String REFERENCE = "Reference";
public final static String CONTACT = "Contact";
public final static String QUOTE_DATE = "Date";

final SingleSelectionModel selectionModel = new 
SingleSelectionModel();

public QuoteTable() {
selectionModel.addSelectionChangeHandler(new SelectionChangeEvent.Handler() 
{
@Override
   public void onSelectionChange(SelectionChangeEvent event) {
QuoteListProxy selected = selectionModel.getSelectedObject();
 if (selected != null && quoteSearchSnapShot != null) {
 quoteSearchSnapShot.loadSnapShot(selected);
 }
  }
   });
initTable();
this.setSelectionModel(selectionModel);
}

private void initTable() {
//setKeyboardSelectionPolicy(KeyboardSelectionPolicy.ENABLED);
initColumns();

for (int i = 0; i < this.getColumnCount(); i++) {
Column c = this.getColumn(i);
if (c.isSortable()) {
this.getHeader(i).setHeaderStyleNames("sortableColumn");
}
}
}

My initColumns() builds out a few TextCells and a few ActionCells. I know 
that the SelectionModel will always fire, even when an ActionCell is 
clicked, and that is the behavior I want but the SelectionChange event does 
not ever seem to get triggered. When I debug, I never even hit the 
breakpoint I have set in the onSelectionChange() method I've defined. Any 
insight would be appreciated? :)

Re: CellTable rebuilding rows unnecessarily

[William Davis]

Or is it not possible for the celltable to only redraw new rows? Will it 
always redraw the whole table when adding to it?

CellTable rebuilding rows unnecessarily

[William Davis]

I have found an interesting issue, and I am wondering if I am misusing or 
overlooking something. I have a large CellTable that is vertically 
scrollable. I want to show all the rows at once instead of traditional 
pagination. So at the bottom of my table I have a row that the user can 
click to load 50 more rows. I have provided the table with a custom table 
builder (setTableBuilder(new Builder());). When the user clicks "load more" 
I query the data, add to the ListDataProvider and 
call table.setVisibleRange(0, dataProvider.getList().size());. 

I put a log statement in the 

@Override
public void buildRowImpl(Object rowValue, int absRowIndex) {
}

method to see when it was building rows. I notice that it would build 
0-dataProvider.getList().size() (all the rows), then it would build 
oldLength-dataProvider.getList().size() (the new rows). For instance, if I 
have 100 rows and then load 50 more it would build 0-150, and then rebuild 
100-50. What I want is for it to only build the new rows, obviously. 

So I start debugging to see why it is rebuilding the whole table each time. 
What I found was in com.google.gwt.user.cellview.client.HasDataPresenter 
it would set the "redrawRequired" flag to true at line 1325:

else if (range1 == null && range0 != null && range0.getStart() == pageStart
&& (replaceDiff >= oldRowDataCount || replaceDiff > oldPageSize)) {
  // Redraw if the new data completely overlaps the old data.
 redrawRequired = true;
}

So my question is why does it think that the new data completely overlaps 
the old data?

Am I using something incorrectly, is there a better way? This gets to be 
quite a slow down when it has to redraw thousands of rows that don't need 
to be redrawn.

Thanks,
Will

Re: CellTable Memory Leak in IE8

[Harvard Pan]

Turns out that my test program no longer leaked because the rows in the
test program's CellTable were no longer being replaced. After I changed the
test program to output different data for each iteration, it became clear
that the rows in the table just never changed. I tracked down the problem
to setting the innerHTML for each row before the call to
tableElement.replaceChild(newSection, section). Once I moved the setting of
innerHTML to null to after this call, the table updates properly, but the
leak still remains.

Upon further testing, the memory leak seems to be largely from the
replaceChild call. I guess if the entire TableSection is replaced in the
DOM, IE8 doesn't properly clean this up, even if you set the innerHTML to
null for the individual rows. I changed the implementation of
replaceTableSection so that it ends up calling replaceAllRowsImplLegacy
(which replaces one row at a time) and this yielded the correct result of
updating the table while also not leaking memory.

Here's the final code that I ended up with in ImplTrident:
// GWT Issue #9164 - https://github.com/gwtproject/gwt/issues/9164
// Discussion thread:
https://groups.google.com/forum/#!topic/google-web-toolkit/lNOKG2dgAzs

/*-{
  row.innerHTML = null;
}-*/;

/**
 * This method is used for legacy AbstractCellTable that's not a
 * {@link TableSectionChangeHandler}.
 */
protected void replaceAllRowsImplLegacy(AbstractCellTable table,
TableSectionElement section,
SafeHtml html) {
  // Remove all children.
  Element child = section.getFirstChildElement();
  while (child != null) {
Element next = child.getNextSiblingElement();
section.removeChild(child);
// GWT Issue #9164 - https://github.com/gwtproject/gwt/issues/9164
// Discussion thread:
https://groups.google.com/forum/#!topic/google-web-toolkit/lNOKG2dgAzs
if (TableRowElement.is(child)) {
setRowInnerHtmlToNull(TableRowElement.as(child));
}
child = next;
  }

  // Add new child elements.
  TableSectionElement newSection = convertToSectionElement(table,
section.getTagName(), html);
  child = newSection.getFirstChildElement();
  while (child != null) {
Element next = child.getNextSiblingElement();
section.appendChild(child);
child = next;
  }
}

/**

 * @param table the {@link AbstractCellTable}

 */
private void replaceTableSection(AbstractCellTable table,
TableSectionElement section,
SafeHtml html) {
  String sectionName = section.getTagName().toLowerCase();
  replaceAllRowsImplLegacy(table, section, html);
  if ("tbody".equals(sectionName)) {
((TableSectionChangeHandler) table).onTableBodyChange(section);
  } else if ("thead".equals(sectionName)) {
((TableSectionChangeHandler) table).onTableHeadChange(section);
  } else if ("tfoot".equals(sectionName)) {
((TableSectionChangeHandler) table).onTableFootChange(section);
  }
}

Again, many thanks for all your help. We couldn't have solved this
otherwise.

No worries, glad it worked! ;)

I've not personally committed any code to the core gwt project but you can 
find out more here 
http://www.gwtproject.org/makinggwtbetter.html#contributingcode

Bear in mind that GWT 3.0 is going to be a very different animal (for 
instance, from what I understand there will be no widgets or gwt-rpc...), 
so perhaps there isn't such a need to get these things fixed... I might be 
wrong though.

Re: CellTable Memory Leak in IE8

[Harvard Pan]

Dave,

Thank you SO much for this. I tested this using my test project and it 
seems to have solved the memory leak completely! I've attached my version 
of the file (modified from 2.5.1-rc1 branch) with your changes.

What's the best way to get this fix to the GWT code base so that future 
versions of GWT will have this fix as well? I'd previously logged Issue 
#9164 (https://github.com/gwtproject/gwt/issues/9164) on the gwtproject 
page.

Thanks again!
Harvard

Re: CellTable Memory Leak in IE8

[DaveC]

Hi,

I think you'll have to dig into AbstractCellTable in order to fix this. I 
did a quick test of a fix I implemented and it "appears" to work for IE11 
running IE8/IE9 mode but not IE10 mode, I've not tested it in a real IE8 or 
IE9.

Basically what I did was exaactly what you said - set row.innerHTML to null.

I took a copy of AbstractCellTable (including the package structure) and 
placed it in my test project. In the ImplTrident inner class I've tweaked 
the methods replaceTableSection and replaceAllRowsImplLegacy to set the 
innerHTML to null for each row e.g. 

*private native final void setRowInnerHtmlToNull(Element row)/*-{*
*row.innerHTML = null;*
*}-*/;*

private void replaceTableSection.

 TableElement tableElement = table.getElement().cast();
  
*  Element child = section.getFirstChildElement();*
*  while (child != null) {*
*setRowInnerHtmlToNull(child);*
*child = child.getNextSiblingElement();*
*  }*
  
  tableElement.replaceChild(newSection, section);

.}

 protected void replaceAllRowsImplLegacy(AbstractCellTable table, 
TableSectionElement section,
SafeHtml html) {
  // Remove all children.
  Element child = section.getFirstChildElement();
  while (child != null) {
Element next = child.getNextSiblingElement();
section.removeChild(child);
*setRowInnerHtmlToNull(child);*
child = next;
  }

}

Hope this helps.

Cheers,
Dave

Thanks Thomas for your reply i am able to do with this 
setSortIconStartOfLine  but having one more issue there is lot of space 
between the Label and icon its because of fixed inline styling(i can 
override this but cant have handle because of label length).

Re: Celltable keep selection after updateRowData

[Jens]

setKeyboardSelectionPolicy(KeyboardSelectionPolicy.BOUND_TO_SELECTION)

should work. Keyboard selections are then the same as SelectionModel 
selections.

I removed keyboard-styles from the css and keep the default selectionModel 
instead setting a singleSelectionModel to the celltable. Now it works...

Re: Celltable keep selection after updateRowData

[Manuel]

I had a look at my styles for the celltable. It appears that after the 
reload, the celltable sets the following styles on the selected row:
.cellTableKeyboardSelectedRow, .cellTableSelectedRow

While clicking on another row the cellTableKeyboardSelectedRow is set to 
the new row, the cellTableSelectedRow stays on the old selection.

Since both styles look the same, it appears that there are 2 selected rows. 

I tried to set a NoSelectionModel, but I can still select rows via 
mouse/keyboard and both styles are still applied... 
Anyone know, whats the proper way to get a singleSelection in this 
cellTable?

Regards,
Manuel

Celltable keep selection after updateRowData

[Manuel]

Hi everyone,

I use the gwt celltable and get a problem, when reloading data:
Im using single selection model with it.

So after the celltable is loaded the first time, the data is displayed (9 
records). I select one row and reload the data via a button.
The data gets fetch from server and updateRowData(0,receivedData) is called.

The new data is now displayed and the previously selected row is still 
selected. Thats good.
But when I select another row, the previously selected row stays selected 
and the newly selected line is also selected. So it appears, there are 2 
rows selected, even though I got a single selection model.

Same workflow on the datagrid, do not cause this problem.

Does anyone know, how to solve this?
Thanks in advance.

Regards,
Manuel

CellTable Memory Leak in IE8

[Harvard Pan]

Hello,

Our company uses GWT 2.5.1-rc1 and many of our customers (healthcare) use 
IE8. We were hopeful that the memory leak in CellTable would have been 
addressed by the memory leak fix for FlexTable. That leak (Issue 6938 - 
https://code.google.com/p/google-web-toolkit/issues/detail?id=6938) was 
fixed in 2.6. After grabbing the fix and merging it into the 2.5.1-rc1 
code, we can confirm that FlexTable indeed is fixed and no longer leaking. 
However, we still have leaking resources in CellTable. I've written a small 
sample application to demonstrate the code that leaks. It's available on 
BitBucket for anyone to pull.

https://bitbucket.org/harvardpan/celltableleak/src/3eb0d9941df6fe40b4b09eef0ce1968c6db90da3/src/com/healthfortis/sample/celltableleak/client/CellTableLeak.java?at=master

The root cause of 6938 was described in a Microsoft Connect 
page: 
http://connect.microsoft.com/IE/feedback/details/790340/memory-leak-in-ie9-ie10-tables
In it, it describes multiple reasons for the leak, including:

   - rows with ids
   - cells with ids
   - code that references a row.cells expression, even if it does not store 
   or use the result (that's the fix in 6938)
   - code that does not set row.innerHTML to null after invoking 
   table.deleteRow() for the row.

I imagine that the CellTable leak is related to one of the conditions 
above. I suspect the last one as I never do actually see any setting to 
null of innerHTML in the javascript. Wanted to check in to see if anyone on 
this forum had any ideas on where we could investigate next.

Thanks!
Harvard

Injecting JSNI(Datatables.net) to GWT CellTable to hide/show rows

[Mohammed Sameen]

I am using Datatables js(using JSNI) for showing and hiding the row 
information for my table(which is created using Google web toolkit-gwt 
celltable) link(https://www.datatables.net/examples/api/row_details.html).My 
requirement is on click of Button i need to iterate the table and show 
/hide the information but its not working See below is my code

function format(d) {
  return ''
+ ''
+ 'Full name:'

+ '' + '';}



$wnd.$(function() {

var table = $wnd.$('#example').DataTable({
"columns" : [ {

"orderable" : false,
"data" : null,
"defaultContent" : ''
}, {
"data" : "firstName"
}, {
"data" : "middleName"
}, {
"data" : "lastName"
}, {
"data" : "age"
}, {
"data" : "empId"
}, {
"data" : "address"
} ],
"order" : [ [ 1, 'asc' ] ]
});

$wnd.jQuery('#btnId').click(function() {



$wnd.$("#example tbody tr").each(function(i) {  
var rowNo = table.row(i);

if (rowNo.child.isShown()) {
// This row is already open - close it
console.log("hide-->");
rowNo.child.hide();
} else {
console.log(rowNo.data());
  rowNo.child( format(rowNo.data()) ).show();
}
});
});
});


and finally i saw one difference is that the table which is created using GWT 
generates the table structure in this format. xxxyyy

since text will be there inside div which is inside td.How to solve this 
issue?How to show/hide the row inside the table?any help?

or Any other way to develop this feature using 
GWT(https://www.datatables.net/examples/api/row_details.html)?

Re: How to implement Expandable-Collapsible Rows in CellTable ?

[Larry L]

Hi,

I have a follow up question about this CustomDataGrid example.
My DataGrid is enabled for selection. So I can select/highlight the major 
rows.
But how do I get the selected minor-rows? 

for example, my code is like this:
SelectionModel model = dataGrid.getSelectionModel();
But the minor rows are not in my SelectionModel.

Thanks,
Larry

See CellTable

Re: Not Able to attach events on CellTable using native Javascript

[Raphael Garnier]

Hi,

jquery works on DOM elements.  When you're attaching the celltable there is 
a render process that constructs the DOM. You should call jquery only when 
"all is done".
Usually, I use the scheduleDeferred method of Scheduler to do that.

Furthermore, you should take a look at GQuery, so you could do jquery in 
java code (no JSNI).

An example from my app :

Scheduler.get().scheduleDeferred(new ScheduledCommand() {
  @Override
  public void execute() {
   list.getElement().appendChild(sortElement);
   gqCells = $(list).find(".cellListEvenItem, .cellListOddItem");
   gqCells.addClass(sortHandlerAppearance.css().sortedElement());
   gqCells.each(new com.google.gwt.query.client.Function() {
   ...

Not Able to attach events on CellTable using native Javascript

[Ramesh]

Hi 
I am attaching events on cell table data using native javascript(jquery), 
but the events are not binding and what i have discovered is, If I use 
these along with setTimeout(..,1) function, the events are binded and 
working properly.

This is the code i have used in UIBinder's java file.
   @Override
protected void onAttach() {
super.onAttach();
clearRequiredValidatorOnNew();
}

  $wnd.setTimeout(function() {
   $wnd.jQuery('.icon-pencil').click(function(e) {
if ($wnd.jQuery(this).text().trim() == ''){
$wnd.jQuery(this).closest('form').find('.reqField').each(function() {
$wnd.jQuery(this).css('background','transparent');
$wnd.jQuery(this).prev('label').removeClass('text-warning');
$wnd.jQuery(this).prev('label').children('span.reqIndic').css('visibility', 
'hidden');
});
}
});
}, 1500);
Here the class .icon-pencil will reside in CellTable(data).

Please suggest how i can use this without timeout.

Re: Hide Column in CellTable

[Jens]

I see. On the  element you need to use "visibility:collapse" to hide 
the entire column. However browser support is pretty poor for it, seems to 
only work well in Firefox.

The other thread you have linked pretty much has all information available 
to solve your issue. Basically you have to show/hide each cell in a column 
like the guy in the last post did with JQuery.

If the number of columns in your table is fixed and known then you could 
also use the following css (example for 3 columns):

/* thead: th cells */
.hide-col-1 th:nth-of-type(1),
.hide-col-2 th:nth-of-type(2),
.hide-col-3 th:nth-of-type(3),
/* tbody/tfoot: td cells */
.hide-col-1 td:nth-of-type(1),
.hide-col-2 td:nth-of-type(2),
.hide-col-3 td:nth-of-type(3) {
display:none;
}

Then you can add/remove "hide-col-1" to the table and the corresponding 
column will be hidden. Here is a jsfiddle that hides the second 
column: http://jsfiddle.net/odbqq04x/

Re: Hide Column in CellTable

[Abdullah]

Hi Jens,
Thanks for your reply,
It is normal CSS only,not cssResource see the below snapshot

<https://lh5.googleusercontent.com/-2yVSY7erPy8/VRGlUc_O1nI/AIM/t_zT__44McU/s1600/CellTable.png>
CSS which are applied to the celltable column is appear on colgroup. Any 
Clue?


Hopefully it is a normal CSS file and not a CssResource? Check your 
browsers dev tools to see what is going on with your css.

https://groups.google.com/forum/#!searchin/google-web-toolkit/hiding$20column$20in$20celltable/google-web-toolkit/3XFe2jwI2ks/E_hDjEej5E8J

 Lot of suggestion is to use* add/removeColumnStyleName* but i used the 
same in my code but still not able to hide the column.See the below code 
snippet..

*Code:*
TextColumn empIdTxt = new TextColumn() {
@Override
public String getValue(ContactInfor object) {
return object.empId;
}
};
cellTable.addColumn(empIdTxt, "EMPLOYEE ID");

TextColumn addressTxt = new TextColumn() {
@Override
public String getValue(ContactInfor object) {
return object.address;
}
};
cellTable.addColumn(addressTxt, "ADDRESS");
cellTable.setRowData(loadContactInfo());
*cellTable.addColumnStyleName(1, "hide"); // added stylename to the Column 
with index 1*
*CSS:*
Added this class in stylesheet
 * .hide* {
display: none;
}   
Is any other think is missed out here?

Re: Wrapping JavaScript into GWT CellTable

[Abdullah]

Hi Thomas,
 Sorry, the Suggestion which you are given is working fine I Use "*flush()*" 
statement after loading data 
 
table.setRowData(loadContactInfo());  
  *  table.flush();*//flush force to render immediately
loadGridData();

 private List loadContactInfo() {
// To load data
List lstContact = new ArrayList();

lstContact.add(new ContactInfor("XXX", "YYY", "t", "26", "0300",Big 
Street"));
return ContactInfor;
}
 
public static native void loadGridData()/*-{
   //calling js for grouping functionality which contains table tr 
element
 }-*/; 

Thanks Thomas for your valuable suggestion.

Wrapping JavaScript into GWT CellTable

[Abdullah]

Hi,
In GWT Cell Table I am wrapping jquery functionality (like grouping) Using 
JSNI. But its throwing JavaScriptObject Exception(function is undefine).I 
am calling this JSNI method once after the data is loaded


*table.setRowData(loadContactInfo());  //To Load Data*
*loadGridData();//Calling JSNI For Grouping *



* private List loadContactInfo() {// 
To load data List lstContact = new ArrayList(); 
lstContact.add(new ContactInfor("XXX", "YYY", "t", "26", 
"0300",Big Street"));return ContactInfor;} 
public static native void loadGridData()/*-{   //calling js for 
grouping functionality which contains table tr element }-*/; *

Since its taking some few millisecond to redraw the cell table before that 
itself the JSNI method is called which throws JSO exception.Is there any 
other to wrap the JS into Cell table after the data gets loaded and 
Rendered? Any Suggestion on this?

Add label next to SelectAll Checkbox in GWT CellTable column header

[BM]

I have a cell table and first column is row selection made of Checkboxes. 
The column header is custom SelectAll (Checkbox). Currently that column 
header only shows checkbox and the selectAll functionality works fine. 

What I want is to have a label next to SelectAll checkbox to basically 
refer that column header better. So it should look like --> [] Select All 

where [] is custom Select All header. 

Is there way to do that?

Please advise. Thanks.
