Editor Dialog with CellList does not display DockLayoutPanel

2011-11-03 Thread Maiku

Hello,

I have UIBinder class that extends DialogBox and implements
HasDataEditor using a CellList. I want to show the CellList on the
left hand side of the DialogBox and an editor on the right-hand side
for editing a selected item.

However, when I try to put a DockLayoutPanel the screen does not
render it or any widgets it contains (but it still takes up space if I
specify width and height on the DockLayoutPanel).  The strange thing
is that after a lot of testing I can show the same dialog without the
HasDataEditor attached to any POJO and the DockLayoutPanel will appear
just fine.

Does anyone know if there is an issue with Editor + DockLayoutPanel or
CellList + DockLayoutPanel appearing in a DialogBox?

(I can provide code if necessary this issue has been driving me
crazy for a few days now).

Re: Inserting Widgets and simple text into panel

2011-11-03 Thread Thomas Broyer

As Ice13ill said, setting innerText or innerHTML will break the w1 and w2 
widgets (their element are rebuilt, so the instance they reference are no 
longer in the document, and event handlers obviously fails too (no longer 
registered, to begin with)).

If using a Label or HTML (or InlineLabel/InlineHTML) is not an option:
   String w1Id = HTMLPanel.createUniqueId();
   String w2Id = HTMLPanel.createUniqueId();
   HTMLPanel panel = new HTMLPanel("large text");
   panel.addAndReplaceElement(w1, w1Id);
   panel.addAndReplaceElement(w2, w2Id);

Alternatively, something can be hacked that way:
   flowPanel.add(w1);
   flowPanel.add(w2);
   flowPanel.getElement().appendChild(Document.get().createTextNode(...));
Use at your own risk.

Re: UIBinder and interface design

2011-11-03 Thread Thomas Broyer

First, "layout panels" are not what you're looking for (no "global 
scrollbar").

IMO, you'd better use plain old HTML+CSS for the layout (i.e. with an 
HTMLPanel as the root), with SimplePanel and FlowPanel where you need to 
dynamically "inject" widgets (main panel).
Or possibly putting your layout code right into your HTML host page and use 
RootPanel.get("main") to get slots where to dynamically "inject" widgets.

Re: RootPanel.get().clear();

2011-11-03 Thread lineman78

RootPanel.clear is inherited from Panel.  The source has it iterating
through the logically attached children and removing them so it should
just remove anything you added from the current GWT module.  If you
wanted to clear everything you would call
RootPanel.get().getElement().setInnerHtml("");

Re: Inserting Widgets and simple text into panel

2011-11-03 Thread Steve Moyer

Try:

flowPanel.add(w1);
flowPanel.add(w2);
flowPanel.getElement.setInnerText(flowPanel.getInnerHTML() +
largeText);

This might be dangerous in some instances, but the widgets should be
well-formed HTML, so adding your text to the end should work.

Good luck!

Notification Mole styling

2011-11-03 Thread Skip

I'm a bit dense when it comes to CSS styling in general so please bare
with me.

We are using the NotificationMole in our application.

I have it's use defined in our main app shell ui binder xml file as
follows.

We are using one of the deprecated css methods where we define our
main css in our gwt html page.

The mole css styling is defined as follows. I'm trying to get the
mole to be a yellow background color.

.mole{
color:#55;
background-color: #EECD00;
}

However, this styling only changes the outer div background color, as
the default coloring remains for the mole, as defined in the
NotificationMole.ui.xml, which is here for reference

http://google-web-toolkit.googlecode.com/svn-history/r8313/trunk/user/src/com/google/gwt/app/client/NotificationMole.ui.xml

So my basic question is, what do I do to override the styles in the
ui.xml file, specifically the colors in the .centered style so they
match my color scheme?

Here's the html that gets generated. The obfuscated style names
reference styles that match the attributes as specified in the
NotificationMole.ui.xml.

Thanks,
Skip

to mix them to build that interface.

Re: IE9 fails to set image dimensions after image load

2011-11-03 Thread Thad

The fix (as noted on issue #6848):

the load handler *MUST* be set prior to the IMG's src attribute *and*
the IMG *MUST* be added to the DOM first.   This is because IE loads
the image asynchronously as soon as the src attribute is set.  So you
need to do this:

Image image = new Image();
image.addLoadHandler(new LoadHandler() { ... });
image.getElement().getStyle().setVisibility(Style.Visibility.HIDDEN);
RootPanel.get().add(image);
img.setUrl("android.png");

Also, IE (at least IE6 as I remember) doesn't calculate dimensions for
objects with display:none, which is why I changed the call
to .setVisible() to .getStyle().setVisibility(...);

Handling browser-based text size

2011-11-03 Thread GeorgeS

My app is working pretty well but I would like to see if there is a
way to handle the case where the user has set the text size in their
browser to some larger size? I'm using pretty standard GWT widgets for
everything and when used with normal sized fonts everything looks fine
but when the user has changed the font I get text overflows and
controls end up overrunning each other.

I know this is going to involve some client-side work but want to make
sure I'm not missing some simple cross-browser fix.

Thanks!

I tried to get your example work, but it failed. I can display other 
ui-elements like buttons, but not cellTree is shown. My Entrypoint looks 
like this:

package com.myproject.client;


import com.google.gwt.core.client.EntryPoint;

import com.google.gwt.user.client.ui.RootPanel;


public class Playing implements EntryPoint {


public void onModuleLoad()

{

SampleCellTree tree = new SampleCellTree();

RootPanel.get().add(tree);

}

}


Why is no cellTree shown?

Thanks in advance

Re: MVP Pattern

2011-11-03 Thread Christian Goudreau

Well activities and presenter really look alike and the two denomination
are confusing, but a hint is the presenter interface in Gwt tutorials that
point to a presenter interface that Activities usually implements.

There's no difference. Activities & Places are mostly about navigation. 
Many people make their activity their presenter. When you create an "MVP" 
project in Eclipse, it uses Activities & Places, and I believe the 
activities are "MVP presenters" (not sure, never tried it)

IE9 fails to set image dimensions after image load

2011-11-03 Thread Thad

Using GWT 2.3 and 2.4, IE9 does not set the dimensions of an image
after the image is loaded. In the code fragment below, IE9 will print
"dimensions: 0, 0":

  Image image = new Image("android.png");
  image.addLoadHandler(new LoadHandler() {
public void onLoad(LoadEvent event) {
  GWT.log("dimensions: "+image.getWidth()+" x "+image.getWidth());
}
  });
  image.setVisible(false);
  RootPanel.get().add(image);

This makes it impossible to scale or crop and image for display in an
SVG Canvas.

Firefox, Chrome, and Safari all give the correct dimensions.

Eclipse ann GWT serialization

2011-11-03 Thread Steve Parker

I currently have an issue when trying to run hosted mode through
eclipse where the serialization policy filename is different to the
compiled version.
Also I have noticed that a new compile or a page refresh during hosted
causes a new policy file to be created again with a different filename
despite no changes being made to any of the source code.
This makes trying to debug my application impossible wherever an RPC
call is made, can anybody point me at areas to look at to try
rectifying this?

Re: Possible to get HTML from a widget?

2011-11-03 Thread Danny Kirchmeier

Maybe you'll want to be using the GWT 2.4 docs instead of the GWT 1.4 docs 
you seem to have.
http://google-web-toolkit.googlecode.com/svn/javadoc/2.4/index.html

Anyway, from the Widget you can call 
widget.getElement()
 and 
from that element you can call 
element.getString(),
 
which will get you the full html, including it's own tag.

J2EE dependencies with GWT plugin for Eclipse

Anyone knows what happened to 'j2EE dependencies ' option after
installing the GWT plugin and creating a project in Eclipse? I use
this to force Eclipse to copy 'user library' jars into the WEB-INF/lib

manually now, which defeats a bit of the purpose for the User-

Re: Dynamic row/cell colors in CellTable

2011-11-03 Thread tachoknight

Okay, I think I "solved" it though there is probably a better way, I'm
guessing. In my case I'm just trying to render a table;  I do not need
dynamic coloring *after* the table is shown (e.g. I'm not rendering
stock prices which might be colored red or green as the price goes
down or up), so I just needed the colors while the table is being
created. Setting the colors on the rows don't seem to work because the
element count of the table is 0 until it's fully rendered.

The way I did it is to add two more members to the data type class,
foreColor and backColor. Then when I'm setting the columns, I use the
SafeHtmlBuilder to wrap the values in a div with a separate style tag.
Here's the code (based on the GWT CellTable example):

public class GWTCellTableColors implements EntryPoint
{
// A simple data type that represents a contact.
private static class Contact
{
private final Stringaddress;
private final Stringname;
private final StringforeColor;
private final StringbackColor;

public Contact(String name, String address, String foreColor, 
String
backColor)
{
this.name = name;
this.address = address;
this.foreColor = foreColor;
this.backColor = backColor;
}
}

// The list of data to display.
private static ListCONTACTS= Arrays.asList(new
Contact("John",

"123 
Fourth Road",


"FF",


"00"),

new Contact("Mary",

"222 
Lancer Lane",


"7cd24d",


"5200a4"),

new Contact("Zander",

"94 
Road Street",


"7cd24d",


"5200a4"));

public void onModuleLoad()
{
final SafeHtmlCell coloredCell = new SafeHtmlCell();

// Create a CellTable.
CellTable table = new CellTable();

Column nameColumn = new Column(coloredCell)
{

@Override
public SafeHtml getValue(Contact object)
{
SafeHtmlBuilder sb = new SafeHtmlBuilder();
sb.appendHtmlConstant("");
sb.appendEscaped(object.name);
sb.appendHtmlConstant("");

return sb.toSafeHtml();
}

};

// Make the name column sortable.
nameColumn.setSortable(true);

// Create address column.

Column addressColumn = new Column(coloredCell)
{

@Override
public SafeHtml getValue(Contact object)
{
SafeHtmlBuilder sb = new SafeHtmlBuilder();
sb.appendHtmlConstant("");
sb.appendEscaped(object.address);
sb.appendHtmlConstant("");

return sb.toSafeHtml();
}

};

// Add the columns.
table.addColumn(nameColumn, "Name");
table.addColumn(addressColumn, "Address");

Re: How to set the path to SDK relatively in Eclipse

2011-11-03 Thread Joel

Indeed, it was that (didn't know where to look for them anymore).

But now the problem is how to use them.

In the Add dialog, whether I put ${ECLIPSE_HOME}/plugins
$ECLIPSE_HOME/plugins  $ECLIPSE_HOME$/plugins or  %ECLIPSE_HOME%/
plugins I can't confirm because the OK button is disabled.
There is also an additional message saying "The installation directory
does not exist" (and NOT "C:\eclipse\plugins\gwt-user.jar is missing"
which tells me it cannot dereference the given variable)

Am I right ?

Re: How to add click events to multiple images in a cell/celltable

"imageLink"))) {
@Override
public String getValue(Step s) {
if (ct.getVisibleItems().indexOf(s) == 0) {

}
return "images/up_16x16.png";
}
};
imageUpCell.setFieldUpdater(new FieldUpdater() {
public void update(int index, Step step, String value) {
if (value.endsWith("up_16x16.png")) {
// Swap implementation
}
}
});
hasCells.add(imageUpCell);

Column imageDownCell = new Column(new
ClickableCellDecorator(new CustomImageCell(16, 16,
"imageLink"))) {
@Override
public String getValue(Step s) {
if (ct.getVisibleItems().indexOf(s) == ct.getRowCount() - 1) {
return "images/transppixel_1x1.gif";
}
return "images/down_16x16.png";
}
};
imageDownCell.setFieldUpdater(new FieldUpdater() {
public void update(int index, Step step, String value) {
if (value.endsWith("down_16x16.png")) {
// Swap implementation
}
}
});
hasCells.add(imageDownCell);

Column sortColumn = new Column(new
CompositeCell(hasCells)) {
@Override
public Step getValue(Step object) {
return object;
}
};
ct.addColumn(sortColumn);
ct.setColumnWidth(sortColumn, 50, Unit.PX);

Dynamic row/cell colors in CellTable

2011-11-03 Thread tachoknight

Hi all-

I am trying to set the colors of a row in a CellTable dynamically,
without CSS. The reason is that the user can choose the color that she
wants to see the results in (hot pink text on red? Sure, no
problem...) and I have found no way to do this; it's easy to to use a
RowStyles class for when you need to dynamically set the row color,
but it seems to only work by returning references to the existing CSS
file; I want to return a string with an actual hex value.

Thanks for any info!

Re: Inserting Widgets and simple text into panel

because widgets have much more that simple html elements (for example click

Celltable column click throws exception (only first time)

2011-11-03 Thread Thomas Trebbien Pedersen

Hi,

I have a celltable with a NoSelectionModel as the selection model.
When clicking a column/row an edit panel is shown and the celltable
panel is hidden.

The strange thing is that when clicking a column for the first time
the below exception is thrown but all subsequent clicks on the same
column does not throw the exception.

Exception thrown on first time column click:
com.google.gwt.core.client.JavaScriptException: (Error): Can't move
focus to the control because it is invisible, not enabled, or of a
type that does not accept the focus.

Does anyone know what's going on here? Or have a suggestion for a fix.

Also tried with a SingleSelectionModel but same thing happens so I
don't think it has anything to do with the selection model.

Thanks.

Ruler tool for GWT maps

2011-11-03 Thread Ben

Hi GWT/Mappers - Has anybody built a ruler tool to enable measuring
between 2 points *on a map created via GWT* in java?  An example or
sources would be appreciated. I suppose either JSNI or GWT version is
ok.. I'm using an older ver. of GWT - 2.1.
Thanks.

Inserting Widgets and simple text into panel

2011-11-03 Thread Ice13ill

Hello, I want create a panel with a flow layout (for ex. FlowPanel)
which contains 2 widgets and a large text at the end (not a  or
another element)
I tried to add the widgets and then set the panel's element text:

flowPanel.add(w1)
flowPanel.add(w2)
flowPanel.getElement.setInnerText(largeText)

but the last line overrides all other widgets.

How can i do this (but without using UIBinder for now.) ?

Re: Activities and Places - Handling several views

Hi,

I've looked into your code but it doesn't seem to fit my need. Basically I
need that a single activity update several views. Do you (or anyone else)
have a clue on how to achieve that?

Thanks a lot,

Antoine.

Re: Gwt-App totally blocks Browser-UI

2011-11-03 Thread Jens

If you load that 16k items with GWT-RPC your first problem that freezes 
your browser is probably the deserialization process when receiving the 
answer from the server (converting the string received back to your object 
graph / list). So comment out all your tree stuff and first solve the 
freeze caused by the request itself.
What you can try is to avoid GWT-RPC for this request and instead use plain 
JSON. If your browser freezes even with JSON then you have to load less 
data or live with the freeze. Keep in mind that an animated loading 
indicator (e.g. animated gif) will also freeze once the browser freezes 
because the browser does not have the time to animate the image.

Once you have solved the freeze caused by GWT-RPC you can optimize the tree 
view if you still see some freeze. A good way to optimize a view is to only 
add the specific data to the view that is currently visible or if you 
really need to add everything then use an IncrementalCommand with the 
Scheduler.

Which browser are you using? Do you reproduce it in a different browser? Do 
you reproduce it in prod/web mode?

Re: Exception thrown by FlexTable

2011-11-03 Thread Erik

Is it possible that the List 'data' contains a null value?
and that  data.passenger_origins.get(i-1) = null?

This can explain the message 'JS value of type null, expected int'

greets

Re: Google Web Toolkit for Web and Mobile development

2011-11-03 Thread Thomas Broyer

Have a look at 
http://www.google.com/events/io/2011/sessions/using-gwt-and-eclipse-to-build-great-mobile-web-apps.html
 and 
the "mobilewebapp" sample from the GWT SDK (which I believe is more or less 
the "Cloud Tasks" example from the presentation)

Re: Gwt-App totally blocks Browser-UI

2011-11-03 Thread tanteanni

it's an tree with 16k items (all administrative units of germany) - the 
main advantage to load all items is, i got a very fast live search on the 
tree. but as i said before i don't want to discuss this here. i ask how to 
get an loading overlay/progress bar that doesn't freeze on loading.
i saw many of them in all the gwt/other framework's showcases. so how to 
use scheduler or something else to keep a loading icon moving and the 
browser responsive?

thx in advance?
