[Insight-users] How to handle x, y, w and h of a rectangle with the mouse with vtk?

[Cary lorey]

thank you for your reply, I tried this example but I have not found a
solution to recover the parameters : x, y, length and width of the
widgetborder.
I actually need these parameters (x,y,h,w)because I have a method to detect
a region of interest with the mouse handling and need x, y, h, w of the
widgetboder.

have you an idea please ?thank you
