OnMouseOver does not activate for TabPanel - bug?

[dam1an]

I have a tab panel with tabs (taken from BasicTabPanel example). I want to listen for mouseover event on each panel so that I can display each panel (rather forcing the user to click the tab panel).

I can trigger this event on the TabPanel itself but not on each individual panel. Is this a bug or am I doing something wrong?

Thanks,
Damian



VerticalPanel vp = new VerticalPanel();
vp.setSpacing(10);

TabPanel panel = new TabPanel();
panel.setPlain(true);
panel.setSize(450, 250);

final TabItem normal = new TabItem("Search");
normal.addStyleName("pad-text");
normal.addText("Autocomplete textfield to go in here...");

normal.addListener(Events.OnMouseOver, new Listener<ComponentEvent>() {
public void handleEvent(ComponentEvent be) {
Window.alert("SearchTab Was Selected");
}
});
panel.add(normal);

...

vp.add(panel);
add(vp);
