Re: how do i add a tooltip to a column header in a celltable ?

Do you suggest something like this ? It's not firing any event when I move the mouse over ....

Column<myDTO, String> utilisateurVerrouColumn = new Column<myDTO, String>(           
new ClickableTextCell(blablaRender)) {
           
public String getValue(myDTO d) {               
    return "something";
}
                   
protected void onBrowserEvent(Event event) {
    //super.onBrowserEvent(event);

    String eventType = event.getType();
    boolean isMouseover = "mouseover".equals(eventType);
    boolean isMouseout = "mouseout".equals(eventType);

    // Get the event target.
    EventTarget eventTarget = event.getEventTarget();
    if (!Element.is(eventTarget)) {
    return;
    }
   
    switch(DOM.eventGetType(event)) {
        case Event.ONMOUSEOVER:
            Window.alert("Mouseover");
            break;                       
            case Event.ONMOUSEOUT:
            Window.alert("Mouseout");
            break;
        default:
             break;
    }
}

};

thanks for your answer.
I had already explored that onBrowserEvent(...) possibility.

Where do i add that OnBrowserEvent(...) method to exactly ?

You must do a event handler (overwrite onBrowserEvent2), CellTable in gwt 2.3.0 doesn't support events. See this example:

@Override
protected void onBrowserEvent2(Event event) {
super.onBrowserEvent2(event);

String eventType = event.getType();
boolean isMouseover = "mouseover".equals(eventType);
boolean isMouseout = "mouseout".equals(eventType);

// Get the event target.
EventTarget eventTarget = event.getEventTarget();
if (!Element.is(eventTarget)) {
return;
}
final Element target = event.getEventTarget().cast();


You can overwrite this method and can open a tooltip.
