There also is a library which makes some css3 work on old IE easier,

so you don't have to implement the special pie selectors yourself, the 
library automatically ads them to the IE versions.

you could use the unobfuscated version of the project to create the

The setFrozen(true) is really important if the proxy you're copying is being

the context.edit changes the state from frozen to not frozen.

Short answer is no.

Re: AbstractCellTable is different in source and in 2.4 release.

[Jeff Larsen]

Those changes to AbstractCellTable were just committed within the last 
couple of weeks and has been going under some pretty heavy changes. They 
usually like to let things like that bake for a while before actually 
releasing them.

That being said, there is no reason to not use a version of trunk. Google 
does it for all their products and Ray Ryan said in this year's Fireside 
Chat that he would develop from a version of trunk and not wait for official 
releases. We're doing just that where I work, I'm in the process of 
upgrading my company to a pull of trunk from last week mainly for the exact 
reasons you specify the table and header builders.

Re: CellTable / Column based on NumberCell, wrapping problem

[Jeff Larsen]

you'll just have to add it with

There is a method

  public void setCellStyleNames(String styleNames) {
this.cellStyleNames = styleNames;
  }

where it links to a style where you set

Re: Help! Some confusing problems about gwt rpc with generics!

[Jeff Larsen]

Don't send List over rpc. The serializer has to take every impl of List and 
create a serialization policy for it. Try it with ArrayList and see what you 
get. 

Also, K has to be defined as something, preferably something as strongly 
typed as possible. And all instances of T and K must also be serializable. 

in short, creating a generic rpc service this way is going to be a 
nightmare. Check out the command pattern for solving this problem. Look into 
gwt-dispatch or gwtp also has a dispatching framework. .

Re: Using a CellTable with individual Cell selection

[Jeff Larsen]

The behavior is from the CSS. It isn't a hack to remove it. 

You just need to change it so you're not using the stock css anymore. If 
you're using cellTable

you'd want to edit one or both of the following 2 css properties.


.cellTableSelectedRowCell {
  border: selectionBorderWidth solid #628cd5;
}

/**
 * The keyboard selected cell is visible over selection.
 */
.cellTableKeyboardSelectedCell {
  border: selectionBorderWidth solid #d7dde8;
} 

For example code on how to override the default celltable/datagrid css, take 
a look at this class. The mechanism is the same between both.

Poking in the code of DataGrid, it looks like you could get access to it

HeaderPanel panel = (HeaderPanel) dataGrid.getWidget();
CustomScrollPanel scrollPanel = (CustomScrollPanel) 
panel.getContentWidget();

Admittedly, this isn't very clean, but it looks like it should work.

Re: Extending ComplexPanel: need to have FocusPanel + LayoutPanel functionalities

[Jeff Larsen]

Yea, any panel can implement ClickHandlers, just do a addDomHandler(handler, 
ClickEvent.getType());

that sinks the event as well as adds the handler to the panel. I hadn't 
looked at the source in a while, so I figured it was still the 
sinkEvents(Event.CLICK | Event.FOCUS ) thing, but they've pulled that 
out and now that logic exists in the addDomHandler method. 

You should just be able to do layoutPanel.addDomHandler(new ClickHandler(){ 
... }, ClickEvent.getType());

All you need to do now is extend GwtBundle and override the method that

MyBundle extends GwtBundle{

Re: Using widgets in CellTable

[Jeff Larsen]

One thing I've found that has been working really well for me is the 
following (And this way you don't have to do a lot of extending of classes).

I had a need for all my Columns to have Rightclick ability, so I wrote a 
ContextMenuCellDelegate, which takes a Cell and delegates all methods except 
consumesEvents() which I override to use my one Set which has all 
the Strings of the column + contextmenu.

Then I extended column to do the same basic thing, delegating all methods to 
Column in my constructor with the exception of getCell() and onBrowserEvent

My ContextColumnDelegate delegates the onbrowser to the column then it 
checks to see if the event is of type "contextmenu" and if it is, it fires 
off the ColumnBrowserEventDelegate method that is also is passed in through 
the constructor. This allows me to use all the current functionality of 
existing columns without having to extend every one to add right click 
event.

Re: Using widgets in CellTable

[Jeff Larsen]

I'm not sure that what you're trying to do will work. I suspect it won't 
with one big reason being Columns don't implemenet the same onBrowserEvent 
that Widgets do. 

What you probably need to do is redesign your widget as a Cell. Then when 
you need to use it as a widget, push that cell into CellWidget. 

I'm fully aware of how complicated this could become, but I think this will 
be your best option.

Re: GWT/GPE 2.4.0 RC1 is available

[Jeff Larsen]

Thanks David!

One thing people should be aware of is that if you just use check for 
updates option in eclipse, you won't get the designer. You have to manually 
go back into the download site and select those options. Otherwise I have to 
say this is a very exciting release.

Re: GWT RPC with large data arrays

[Jeff Larsen]

You can test that theory out using RequestFactory, it uses JSON as the

Re: button with image and text

[Jeff Larsen]

I am very new to gwt, so I may be wrong, but from what I understand you need 
to use gwt-ext to change the z index of components.


nope it is a CSS property.  

add this to the style of your TextBox
z-index:-1;

also might be able to do what you need to with Button by using the 
appropriate css selectors. 

http://www.w3.org/TR/CSS2/selector.html

5.11.3 The dynamic pseudo-classes: :hover, :active, and :focus

Interactive user agents sometimes change the rendering in response to user 
actions. CSS provides three pseudo-classes for common cases:

   - The :hover pseudo-class applies while the user designates an element 
   (with some pointing device), but does not activate it. For example, a visual 
   user agent could apply this pseudo-class when the cursor (mouse pointer) 
   hovers over a box generated by the element. User agents not supporting 
interactive 
   media  do 
   not have to support this pseudo-class. Some conforming user agents 
   supporting interactive 
media may 
   not be able to support this pseudo-class (e.g., a pen device).
   - The :active pseudo-class applies while an element is being activated by 
   the user. For example, between the times the user presses the mouse button 
   and releases it.
   - The :focus pseudo-class applies while an element has the focus (accepts 
   keyboard events or other forms of text input).

An element may match several pseudo-classes at the same time.

CSS does not define which elements may be in the above states, or how the 
states are entered and left. Scripting may change whether elements react to 
user events or not, and different devices and UAs may have different ways of 
pointing to, or activating elements.

CSS 2.1 does not define if the parent of an element that is ':active' or 
':hover' is also in that state.

Re: button with image and text

[Jeff Larsen]

Solution 1. Change the z index of the button to have it be on top of the 
text. 

Solution 2: Use Button instead of PushButton and create a SafeHtml Template 
for your text+image. (this is the better option if you don't need all the 
stuff that PushButton provides)

Re: override / overrule a gwt class, AbstractPlaceHistoryMapper

[Jeff Larsen]

Naw, the solution is pretty ugly, copy/pasting code sucks. It has the 
advantage of working quickly. Sounds like you got a better solution, so I'd 
definitely roll with that. The only caveat is that you'll have to be careful 
with GWT version updates now, there are no guarentees that the class you're 
extending won't change and they won't tell you.

Re: Connecting to a oracle database with GWT

[Jeff Larsen]

with GWT you have client and server code. The question you're asking is 
similar to asking where to put the oracle library when using JQuery. GWT 
compiles to javascript and while it has some server side plumbing, that is 
there just to facilitate client/server communication. The answer is you put 
the oracle jar inside your server and only reference it from your server 
side classes.

Re: override / overrule a gwt class, AbstractPlaceHistoryMapper

[Jeff Larsen]

if you look at Place.gwt.xml you'll see that 


  

  

so the class you need to override is PlaceHistoryMapperGenerator

Looking in PlaceHistoryMapperGenerator you'll see imports for 

import com.google.gwt.place.impl.AbstractPlaceHistoryMapper;
import com.google.gwt.place.impl.AbstractPlaceHistoryMapper.PrefixAndToken;

If you did a copy/paste of the code and imported your class extending APHM 
and the PrefixAndToken(possibly) and then in your gwt.xml file did   


  

you should get the result you desire.

But if for instance, the view itself is responsible for reading a TextBox

Re: Java 7

[Jeff Larsen]

Also, GWT added support for Java 5 when Java 1.4 reached EOL, and Java 6 was 
already released, and GWT does not officially support Java 6 (that's going 
to change, and a few features are already there, such as @Override on 
implementations of interface methods, and String#isEmpty); let's hope it'll 
be faster for Java 7, but don't be too impatient IMO.

Are you sure this is true? I thought 1.6 is supported as of 2.3, but not 
required. 1.6 will be required in future releases of GWT however (it may be 
required for 2.3, i'm not sure) but I know commits to trunk are going in 
with @Override on interface methods, so in order to get stuff to compile 1.6 
will be required.

I'm probably just going to abandon this and just manually get/set the
