Re: How can I add a MouseOutHandler to a FlexTable cell?
Based on Kelo's example above:
public class BocaJrsTable extends FlexTable implements
HasMouseOutHandlers {
// ... as above, but add the following:
public int[] getCellForEvent(final MouseEvent? event) {
final Element td =
getEventTargetCell(Event.as(event.getNativeEvent
()));
if (td == null) {
return null;
}
final Element tr = DOM.getParent(td);
final Element body = DOM.getParent(tr);
final int r = DOM.getChildIndex(body, tr);
final int c = DOM.getChildIndex(tr, td);
final int[] idx = new int[] { r, c };
return idx;
}
}
someTable = new BocaJrsTable();
someTable.addMouseOverHandler(new MouseOverHandler() {
@Override
public void onMouseOver(final MouseOverEvent event) {
final int r = row(event);
...
}}
);
public static int row(final MouseEvent? event) {
// note that in general, events can have sources that are not
Widgets.
BocaJrsTable sender = (BocaJrsTable) event.getSource();
final int[] idx = sender.getCellForEvent(event);
if (idx == null) {
return -1;
}
return idx[0];
}
I hope that helps,.
Cheers,
C.

Re: How can I add a MouseOutHandler to a FlexTable cell?
How to find out the row number on which mouseEvent has occured(in
Kelo's example)???

Hi Eduardo,
Here's your solution:
public class BocaJrsTable extends FlexTable implements
HasMouseOutHandlers {
private HandlerManager manager = new HandlerManager(this);
public BocaJrsTable(){
super();
addDomHandler(new MouseOutHandler() {
@Override
public void onMouseOut(MouseOutEvent event) {
fireEvent(event);
}
}, MouseOutEvent.getType());
}
@Override
public HandlerRegistration addMouseOutHandler(MouseOutHandler
handler) {
return manager.addHandler(MouseOutEvent.getType(), handler);
}
@Override
public void fireEvent(GwtEvent? event) {
manager.fireEvent(event);
}
}
Good luck !

Re: How can I add a MouseOutHandler to a FlexTable cell?
Thanks for the example - I have to support 1.5 and 1.6 - so I am still coding to the old event model... But it's nice to see looking inside HandlerManager that they defer editing of the handler list while the event it firing. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
