GXT : GWT Designer and event handler

[eoriou]

I tested different kind of GXT components and when I created a list, a grid or a tree, I expected to find in context menu "Add event handler" the way to add a select event handler or double click event handler to the selected component but I didn't find them. This menu doesn't contain the most frequently used events. Could you tell me if you will improve this point in a near future ?

The "Add event handler" command can be used to create event handlers for any of the standard typed events supported by GWT and GXT. It appears that the GXT API is a bit "lazy" and offers a number of untyped events that do not have normal, typed counterparts. The latest GWT Designer build now adds support for these untyped events which can be configured by right-clicking on the widget and selecting the event type.



Code like the following will be generated:

Code: Select all

button.addListener(Events.Select, new Listener<ButtonEvent>() {
    public void handleEvent(ButtonEvent e) {
    }
});

Hold the Ctrl key down to remove an event handler.

Thank you for this improvement.

I hope that lets you do what you wanted. Let us know if we missed any events on any of the components (we had to build up these lists manually since the normal reflection techniques we use for normal types events would not work).
