DeckLayoutPanel not displaying below banner

[Patrick May]

I have a simple GWT app with a top level UI configured in UiBinder like 
this:


http://dl.google.com/gwt/DTD/xhtml.ent";>


  

  

  
Some H3 Text
Some H2 Text
  

  

  
  

  

 

The CSS is:


.banner {
float: left;
width: 100%;
background-image: url("images/blue-banner.jpg");
background-size: 100%;
}
.banner h2 {
font-size:  60px;
font-family: "Helvetica Neue", "Arial", "Helvetica";
font-weight: 700;
color: #fff;
text-shadow: 3px 3px 3px #000;
margin-top: 3px;
text-align: right;
}
.banner h3 {
font-family: "Helvetica Neue", "Arial", "Helvetica";
margin: 20px 0px 0px 0px;
color: #fff;
font-size: 30px;
text-align: right;
}
.banner-text-left {
float: left;
text-align: left;
margin-left: 20px;
}

.main-deck {
width: 100%;
}
 

The code inserts this simple panel into the DeckLayoutView:


http://dl.google.com/gwt/DTD/xhtml.ent";>


  

  Test Placeholder
  

  

 

When I run the app in devmode, I see the banner and the two text strings, 
but no DeckLayoutView. How do I get that to appear?

Re: GWT 2.8.0 RC2 is here!

[Patrick Tessier]

I'm upgrading from 2.7 to 2.8.1 now, but it seems I'm running into the same 
issue as Tony.  I'm using AppEngine on the server side, which is in the 
same IntelliJ/Maven module as the GWT code.  When launching devmode from 
IntelliJ, I get "Couldn't load project from Super Dev Mode server at...", 
with HTTP 500 "

java.lang.NoSuchMethodError: 
javax.servlet.http.HttpServletResponse.getHeader(Ljava/lang/String;)Ljava/lang/String;"
on the codeserver.

I was convinced that I could rearrange the GWT/AppEngine dependencies in the 
IntelliJ module and
 get it working, but that appears to not be the case.  So I assume that to 
*run* them separately
 would have to mean splitting the client and server sides into separate pom.xml 
within the project
and splitting the dependencies. Correct?

Thanks

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.

 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.

Thanks for the response.

GWT DataGrid does not display, CellTable does

[Patrick May]

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.

SplitLayoutPanel (TestUI)
  |
  + StackLayoutPanel
  |   |
  |   + CellList (Profile)
  |   |
  |   + CellList (Admin)
  |
  + DeckLayoutPanel
  |
  + SimpleLayoutPanel
  |   |
  |   + 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?

how to correctly remove element in gwt (both `DOM.isOrHasChild` & `DOM.removeChild` were deprecated)?

[Patrick Tucker]

The code is open source, you can just look at what the 2 functions do and use 
it instead.  I'm pretty sure they both are just 1 liners.  Also, last I looked 
the deprecation java doc indicates what should be used instead.  They generally 
are really good about doing that.

If memory serves me right you will just call removeChild(element) on your body 
element.  I don't recall what the other is.

As a side note, you should save your returned elements to a variable to reduce 
calls to the DOM.

Styling DataGrid headers

[Patrick May]

I've configured my DataGrid with a custom CSS file like so:

  public interface UsersDataGridResources extends DataGrid.Resources
  {
@Source({DataGrid.Style.DEFAULT_CSS,"usersDataGrid.css"})
DataGrid.Style dataGrid();
  }

  private static final int DEFAULT_PAGE_SIZE = 50;
  private static final UsersDataGridResources usersDataGridResources
= GWT.create(UsersDataGridResources.class);
  static { usersDataGridResources.dataGrid().ensureInjected(); }

  private DataGrid usersGrid_
= new DataGrid(DEFAULT_PAGE_SIZE,usersDataGridResources);

I've specified a normal font in usersDataGrid.css:

.dataGridHeader {
  font-weight: normal !important;
  text-decoration: none !important;
}

This isn't being reflected in what I see when the grid is rendered.  I'm 
specifying the column headers as simple strings, not Cells.  Is there a 
different property I need to configure?

Thanks,

Patrick

UiRenderer with numeric getter

[Patrick Tucker]

For some reason I can't seem to find anything on this, no group posts, 
nothing in the gwtproject.com tutorials, or google search.
 
What I have is a UiRenderer that points to an Object that has a 
getter whose return type is Integer.  When I try to use this getter in a 
ui:text element's for attribute I get an error indicating that a string is 
required.
 
The XML is similar to the following:
 

 
1
 
 
 
I really don't want to change the return type to String or write a 
decorator that returns String instead.  Seems like there should be some 
other way to make this work?
 
Thanks,
Pat

Re: update from 2.4 to 2.5 : uibinder.elementparsers.LazyPanelParser.parse(LazyPanelParser.java:40) error

[Patrick Tucker]

I just ran into this and I'm wondering why a ui:field is required?  In our 
case, the object is self contained and after creation isn't 
referenced by the code that creates the object.  Is this requirement really 
necessary??
 
I know the workaround is easy, its just that making us developers 
troubleshoot an error that seems to be a completely valid use case with 
very little info seems wrong.  If nothing else maybe a better error message 
should be output?

Connecting a DataGrid to a JSON source

[Patrick May]

I'm looking through the examples and tutorials for DataGrid and, frankly, 
it's a mess.  I want to display JSON data that is being updated from the 
server.  The whole TextColumn mechanism is a lot of overhead that is 
difficult to abstract away.

Is there any alternative that provides similar functionality but is easier 
to use and that integrates well with the rest of GWT?

I just tried wrapping the DockLayoutPanel in a VerticalPanel and it

Not knowing why this works makes me nervous, though.

Thanks for the explanation.  My goal is to have the DockLayoutPanel in a 
div, because I have other elements in my page so I can't give the whole 
body to the DockLayoutPanel.  If I understand you correctly, the only way I 
can accomplish this is to set my div to have position:absolute or 
position:relative and to fix it's size.  I don't know the size to fix -- 
I'd just like it to take whatever it needs.  Is there any way to accomplish 
that?

Thanks again,

Patrick

DockLayoutPanel displays in body, not in div

[Patrick May]

I have a GWT UI with a DockLayoutPanel as the root widget.  When I use 
RootLayoutPanel.get() to add it to my HTML page like this:

RootLayoutPanel.get().addStyleName("root-layout-panel");
RootLayoutPanel.get().add(dockLayoutPanel_);

it displays fine.

When I try to put it in a div like this:

RootPanel.get("ui").add(dockLayoutPanel_);

Nothing displays and I get this error in Safari:  TypeError: 'undefined' is 
not an object (evaluating 'c.gwtOnLoad')

Interestingly, I have another app that has a VerticalPanel as its root and 
I'm able to add that to a div without a problem.  Is there something odd 
about DocLayoutPanel that I'm missing?

Thanks,

Patrick

Invalid RPC Token

Uncaught com.google.gwt.user.client.rpc.RpcTokenException: Invalid RPC 
token (Invalid RpcToken type: expected 
'com.google.gwt.user.client.rpc.XsrfToken' but got 'class 
com.google.gwt.user.client.rpc.XsrfToken') 

I downloaded the GWT 2.6 code using GIT and have grepped the code. I see 
that the file that is doing this is 
com.google.gwt.user.rebind.rpc.ProxyCreator.java 
in the method generateCheckRpcTokenTypeOverride. However, I'm at a loss to 
what it means. I have checked my class path for duplicate instances of 
XsrfToken but it is only found in gwt-servlet.jar in my war file.

Any ideas? Below is the copied generateCheckRpcTokenTypeOverride method.

Thanks in advance!

Patrick


  protected void generateCheckRpcTokenTypeOverride(SourceWriter srcWriter, 
TypeOracle typeOracle,
  SerializableTypeOracle typesSentFromBrowser) {

JClassType rpcTokenType = typeOracle.findType(RpcToken.class.getName());
JClassType[] rpcTokenSubtypes = rpcTokenType.getSubtypes();

String rpcTokenImplementation = "";

for (JClassType rpcTokenSubtype : rpcTokenSubtypes) {

  if (typesSentFromBrowser.isSerializable(rpcTokenSubtype)) {

if (rpcTokenImplementation.length() > 0) {

  // >1 implematation of RpcToken, bail

  rpcTokenImplementation = "";

  break;

} else {

  rpcTokenImplementation = rpcTokenSubtype.getQualifiedSourceName();

}

  }

}

if (rpcTokenImplementation.length() > 0) {

  srcWriter.println("@Override");

  srcWriter.println("protected void checkRpcTokenType(RpcToken token) {"
);

  srcWriter.indent();

  srcWriter.println("if (!(token instanceof " + rpcTokenImplementation 
+ ")) {");

  srcWriter.indent();

  srcWriter.println("throw new RpcTokenException(\"Invalid RpcToken

  + rpcTokenImplementation + "' but got '\" + " + "token.getClass()

Re: How can I set correct size of widgets in a SplitLayoutPanel ?

[Patrick Tucker]

jaga was pointing out that your FlowPanel is not equipped to resize the 
DataGrid.  If you look at DataGrid it implements RequiresResize indicating 
that whatever its parent Widget is must tell it when to resize itself.  You 
could replace the FlowPanel with a LayoutPanel, 
DockLayoutPanel, HeaderPanel or a custom panel.  It really just depends on 
how you want it to act and how much overhead you are willing to accept.  If 
you went the LayoutPanel route, you wouldn't set the DataGrid's size to 
100% allowing it to calculate how many pixels it can occupy.

I didn't look that close at it but maybe you should use the parent element's

Re: Layout with nested SplitLayoutPanel

[Patrick Tucker]

I took your PortalPanel class above and added it to the page using 
RootLayoutPanel.get().add(Widget)

This is what it took to get your widgets sizing properly:

 public void resetSplitters () {

// parent height

int ph = this.getParent().getOffsetHeight();

// parent width

int pw = this.getParent().getOffsetWidth();

  

slp_Outer.setWidgetSize(slp_North, ph/2);

slp_North.setWidgetSize(fp_West, pw/2);

 }


I was able to call this from both onAttach and onResize.

Hope this helps!

To move the splitter, you have to change the size of its associated widget.

Re: Layout with nested SplitLayoutPanel

[Patrick Tucker]

That is what I was going to recommend but I haven't had time to sit down and 
look at all the code you provided.  Glad you were able to figure it out though.

Instead of resizing in your constructor, try overriding onAttach and call the 
resize function in there.  Make sure you call super.onAttach() before resize.  
Depending on how the parent classes are setup you may have to schedule the 
resize.

Hope that helps!

SplitLayoutPanel does not do percentages so you will have to calculate the 
center in pixels.

Believe the function is getChildNodes() or something like that.  Iterate over 
the result and remove whatever is appropriate.

Re: Under GWT Architecture, Should we validate InputData at Client Side or Server Side?

Why do you need an EventBus in your validation code?

 A Server should never trust that the client can be trusted.
  
 The big advantage of GWT is that you can reuse the same code to perform 
 validation on the serverside.

If you have a set size for your header, you most likely should be using a

Re: layout panel problem, invisible panels

[Patrick Tucker]

That is what is so nice about it.  But generally we end up wanting to know 
about the resize to modify elements that are inside of the child 
widget either to reposition or resize them.
 
It is actually an easy fix, unfortunately the new review system isn't me 
friendly.  If anyone wants to take it on you basically just need to add the 
following code to 

forceLayout():

if (header != null && header instanceof RequiresResize) { //added
   ((RequiresResize) header).onResize();
}

if (footer != null && footer instanceof RequiresResize) { //added
  ((RequiresResize) footer).onResize();
}

Re: Problems with overriding .gwt-TabBarItem-selected CSS when using own CSS style instead of .gwt-TabBarItem

[Patrick Tucker]

You are adding the dependent name to the Label itself, this is not really 
what Jens was describing.
 
Your dependent style will look something like gwt-Label-lowerTabBarItem.  
This is not how your style is written.  You should be able to see that the 
style name is not as you expected with something like firebug or IE's 
developer tools.

Re: Problems with overriding .gwt-TabBarItem-selected CSS when using own CSS style instead of .gwt-TabBarItem

[Patrick Tucker]

TabBar.addStyleDependentName("upper")
or
TabPanel.getTabBar().addStyleDependentName("upper")
or
TabBar.getElement().setId("upper")
or
TabPanel.getTabBar().getElement().setId("upper")
 
Maybe if you provide code you will get better help?  You are making us 
guess...

What's the harm in making it implement ProvidesResize and correctly notify

Funny, I also thought it was annoying that the menu jumped around and got so

Re: Problems with overriding .gwt-TabBarItem-selected CSS when using own CSS style instead of .gwt-TabBarItem

[Patrick Tucker]

Did you try giving the TabBar itself a style name like upper and lower?
 
This will allow you to do the following:

.gwt-TabBar-upper .gwt-TabBarItem   

.gwt-TabBar-lower .gwt-TabBarItem

http://www.gwtproject.org/doc/latest/tutorial/style.html#dependent
 
If you gave each element an ID you could reference them by the ID like so:

#upper.gwt-TabBar
#lower.gwt-TabBar

Re: DateBox getDatePicker() and setCurrentMonth()

[Patrick Tucker]

When you create the DatePicker yourself, how are you creating it?  DateBox 
uses the no arg constructor...  If you are providing it with a bad model or 
something like that then it would be at fault not the DateBox or DatePicker.

Have you tried providing, in the java code, the widget that is being added

Some code would probably go a long way in getting better guidance...

Re: mouse over tab (TabLayoutPanel) to select

[Patrick Tucker]

Instead of using add(Widget, String) to add tabs use add(Widget,Widget).  
Your second argument will be a widget that you have added a mouse over 
handler to that will instruct the TabLayoutPanel to select the appropriate 
tab by calling selectTab(int) or selectTab(Widget).

ClientAbortException Issue Since 2.5.1

[James Patrick]

Hey Guys,

The company I work for uses apache + gwt + tomcat7 for our site. I've been 
trying to update from gwt 2.5.0 -> 2.5.1. 
GwtSerlvet.jar used to contain the 
org.apache.catalina.connector.ClientAbortException class.  What is upgrade 
path from 2.5.0 to 2.5.1 for users who are depended on catching 
ClientAbortException (in case I've missed something)?

We put catalina.jar in the classpath to compile.  If we add it to 
WEB-INF/lib tomcat fails to deploy the app, if we don't it just doesn't 
catch that Exception and the error is just caught be a general catch-all.


*The error log for is below:*

I want to use Apache Commons on the server, but the code is using the packages in gwt-dev.jar.

Once on the server the jars in a directory are loaded in alphabetic order if 
not specified otherwise.  You can try renaming the jar to make it come first.

Re: GWT - So terribly slow that makes development hard ... very hard ... extremely hard ...

[Patrick Tucker]

Do you increase the number of workers when you compile?

The arg is localWorkers.  I specify 6, 1 for each permutation, that along with 
a memory spec of 1 gig and my compiles finish in just over a minute.

Re: IE10 support in Gwt

[Patrick Tucker]

There are a couple module config files that need to be updated, and at 
least 1 java file.
 
DOM.gwt.xml
UserAgent.gwt.xml
UserAgentPropertyGenerator.java
 
I also would recommend looking at DOMImplIE9.java and any parent classes to 
see what needs to be modified.
 
I must be missing something because I am still getting the promt: ... 
user.agent value (ie9) does not match the runtime user.agent value (ie10) 
...

NumberFormat output wrong?

[Patrick Tucker]

Today I noticed that the output of my NumberFormat (GWT 2.5.0) is not what 
I thought it had been set to.  So I played with it a little and found the 
output to be inconsistent.
 
The formats:

1: NumberFormat.getFormat("#,###.##")
2: NumberFormat.getFormat("#,###.00")
3: NumberFormat.getFormat("#,##0.00")

 
The output is as follows:

1: 3.57, 0.98, 0.6
2: 3.57, .98, .60
3: 3.57, 0.98, 0.60

 The NumberFormat class doc states the following:

0 Number Yes Digit 
# Number Yes Digit, zero shows as absent 

According to the doc comments, show above, I was expect the following 
output for each format:

1: 3.57, .98, .6
2: 3.57, .98, .60
3: 3.57, 0.98, 0.60

 
 What going on here?  The output for 1 should not have the leading 0, just 
like the 2nd format.
 
Thanks,
Pat

Re: Using Tomcat Websockets with GWT

You should try using GWT.getHostPageBaseUrl() next time.  It might save you the

Why doesn't this (AbsolutePanel inside a ScrollPanel) work?

[Patrick Tucker]

Try absolutePanel.getElement().getStyle().setOverflow(Overflow.AUTO) and get 
rid of the ScrollPanel.  It by default sets overflow to hidden, but it may work.

Re: KeyCodes not containing KEY_SPACE?

[Patrick Tucker]

This bothers me every now and then too.  I do not believe it is in any 
other class.
 
We have to add event handling for the space key all the time because users 
expect space to trigger events the same way the enter key does.  This is 
understandable because browsers, by default, trigger action for certain 
elements when the space bar is hit...
