nanogui: Thread: to receive event only from a YES NO window

Hi all,

I use nano-x with a touchscreen on an eCos and NIOSII platform.
I have to display some YES NO window which cover partially the screen.
I would like to receive events only from these YES NO buttons or from that window but not from other visible buttons/windows.
I don't see how I can do that with a touchscreen or a mouse. 
GrSetFocus() seems only for the keyboard events. 

Could someone help me?
Thanks

I found this : http://sourceforge.net/projects/tinywidgets/

let me know if / how it works for you.

I'm not an expert, but I think you (without using widgets) can easily
use GR_EVENT_BUTTON to get a "mouse click"  location from the touch
screen and calculate from the coordinates what this means.

Again, I am no expert in nano-X, but I suppose this tis what widgets are
made for.

I suppose there are widgets sets that can be used with nano-X. Please
let me know what you find !

I found a way using the Input only window.
Before creating the dialog window I create an Input window which covers entirely the screen and will deactivate the actions on the buttons not covered by the dialog window. Then I create the dialog window. 
I don't select any events for the Input window.
and I select the MOUSE events for the dialog window.

My platform is eCos NIOSII Lcd 640*480 Touch panel.
