Hi,
I am building a GWt app which has the following layout:
- FlowPanel
* Menu Bar
* Grid (2,x)
I want to add keyboard navigation to the Grid (UP, DOWN & DELETE)
I call the following code in the constructor of my Widget:
// EVENTS
Event.addNativePreviewHandler(new NativePreviewHandler() {
@Override
public void onPreviewNativeEvent(final NativePreviewEvent
event) {
// Key pressed
if (event.getTypeInt() == Event.ONKEYDOWN) {
// Update Grid status (up, down, delete)
}
}
});
When I press UP & DOWN keys, no problem I get the events.
The problem is that navigation in the MenuBar also fires key events
which are catched by this code.
So when I select the MenuBar I have a double navigation: in my MenuBar
and in my Grid
The questions are :
- How can I prevent my code to catch events which target elements like
MenuBar & TextField ?
- Is there another way to deal with my problem ?
Thanks
Chris
