Question

I can’t seem to slide to a new, not-rendered-yet widget added to a DeckLayoutPanel, no matter what I try.

It appears without the slide transition if it’s never been rendered before.

However, when I do showWidget(…) back and forward to the new widget, then the slide transition works fine.

Has anybody been able to slide to a not-rendered-yet widget in DeckLayoutPanel? If so how?

I need this functionality.

You can use the scheduleDeferred comand. This will make sure that your slide command is executed, when the widget is actually shown.

It defers some code until after the browser redraws the page (if needed) and pending events are processed (that is after the mouseup and click if this is done in mousedown)

Usage:

Scheduler.get().scheduleDeferred(new ScheduledCommand() {     
  @Override 
  public void execute() {        
    Scheduler.get().scheduleDeferred(/*Your silider comand*/); // reschedule 
  } 
});
