Re: TabLayoutPanel,how to catch the mouse click event on tab

You can use either of the BeforeSelectionHandler or SelectionHandler
for the TabLayoutPanel. If you want to perform your operation after
the tab is clicked use the latter

example:

@UiHanlder("myTabPanel")
public void onMyTabClick(SelectionEvent<Integer> event) {

int item = event.getSelectedItem();

//note item holds the tab id. now compare this against the tab's you
have, index starts from zero.

switch(item) {
case tab1 :
break;
case tab2:
break;
}

}

Thanks
