Re: Combo box in GWT2.4?
We need a combination of a drop-down list or list box and a single- line textbox, allowing the user to either type a value directly into the control or choose from the list of existing options(not suggestbox though).

Re: Preventing selection event propagation
Thank you for your suggestions. I tried the solution suggested by Jens.

Re: Preventing selection event propagation

Re: TabLayoutPanel SelectionHandler invoked multiple times
That was exactly the problem.
I had put it inside a function which was invoked every time a tab is
created. Due to this, selection handler was getting added multiple
times.I moved it to the constructor and now it is invoked just once.
Thanks a lot for the guidance.

If you are adding it in onLoad or some function that is calledmultipletime,
that will explain why it is firingmultipletimes. Add
a print statement before the add and check the output.

Any component like SplitLayoutPanel with percentage support

Is there any component like SplitLayoutPanel which has draggable splitter concept along with size in %.
