I'm looking at some GXT code for GWT and I ran across this use of Generics that I can't find another example of in the Java tutorials. The class name is com.extjs.gxt.ui.client.data.BaseModelData if you want to look at all of the code. Here are the important parts: private RpcMap map; public <X> X get(String property) { if (allowNes...
Hi I am using GWT (Google Web Toolkit) 1.5.3 et GXT (ExtJS) 1.2 I just want to create a simple form with some radio buttons generated after a RPC call, to get some values Code: final FormPanel simple = new FormPanel(); simple.setFrame(true); simple.setWidth(350); simple.setHeaderVisible(false); DateField date = ne...
In GXT, MessageBox methods are asynchronous, meaning that the application does not "lock up" while the message box is displayed. I using a KeyListener to process enter key presses in a form (to increase usability, i.e., allowing the form to be submitted by the enter key) and subsequently disabling the form fields while the application p...
I have a web app that uses GXT (version 1.2.2) grids extensively. I'd like to warn the user if they make changes but don't save. When I use the grid in a popup dialog, the only way for the user to leave is via a button (either Close or OK). If I add a SelectionListener to the Close button, I can do my "isDirty()" check and warn the use...
I cannot seem to find any documentation of what events fire and when in GXT. The API docs have lists of all the events that could fire (in Events). And it describes how to handle events that you catch. But I'm interested in the opposite side, which events are fired when I take a certain action. I can set some listeners for various diff...
I need to see component tree of the GWT application. DOM tree will be also acceptable. Unfortunatelly GWT hosted browser does not provide access for devToolbar. The only way I found is to compile to javascript and then use regular browser. But compilation takes enormous ammount of time. ExtJS has Debug Console, but I was not able to fi...
I'm working with NumberField and NumberFormat. How can I change NumberConstants.decimalSeparator() value without changing my locale? For instance I want to have "." or "," as decimal separators for all locales. Is it possible to create custom property file NumberConstants_bla.properties and force gxt use it instead of standard NumberCons...
I am using Ext-GWT 2.0.1 and GWT 1.6.4 I have a LayoutContainer that uses a RowLayout. The widgets are added to this container with RowData(1,-1), so that when they change in height, the container also changes height accordingly. I want to do something when this LayoutContainer changes size. How can I add a listener that does this? ...

I am using GWT-RPC to populate Ext-GWT TreeGrids with data from a server. I am using 4 callbacks to populate 6 TreeGrids. As the callback onSuccess function modifies the TreeGrid by inserting rows, the TreeGridView needs to render the rows. The callback class is called MainPnlSummaryTablesAsyncCallback. For some reason, when it needs...
Last night, I did a quick spike to try and implement username/password autocomplete in my GXT application. By "autocomplete", I don't mean Ajax-style autocomplete, but rather browser-based autocomplete. The best information I found on this via google is in the following post: http://osdir.com/ml/GoogleWebToolkit/2009-04/msg01838.html I...
Using Dozer to map two objects, I have: /** /* This first class uses the GXT (ExtJS) framework **/ Class1 extends BaseModelData { public int getId() { return (Integer)get("id"); } public void setId(int id) { set("id", id); } // more properties } Class2 { public int getId() { return i...
context: I'm using Ext-GWT and I think ListView is the right layout for what I need. My problem is that I have to use a HTML template for all of my items, but I want to build GWT/Ext-GWT widgets instead, so I'm using div placeholders that I will replace with the proper widgets. How can I replace my div with a widget? my first attempt wa...

I am looking for a way to render the elements of a GXT (GWT-Ext) RadioGroup or CheckBoxGroup in a layout other than a single column (Orientation.VERTICAL) or a single row (Orientation.HORIZONTAL). I see that in ExtJS 3.0, RadioGroups and CheckBoxGroups are easily rendered in multiple columns. However, the configuration doesn't seem to ...
We are using Django as the back end and GXT 2.1 as the front end. Somehow my GXT application cannot communicate with GXT, without using requests in the form say http://localhost/ and so on. Does any one know about how we can go about it? ...
Hello. My question is: what is the best way to send my jee annotated entity beans' data to the clientside to use it in a grid for example? Surely I could make the BaseModel-extended client models for each entity manually, but I wonder what could be the best-practice here. I need a step-by-step tutorial if possible. regards ...

Hi. I'm trying to develop a jee+gxt application. I have an rpc call which calls a session bean's method.
