[wxhaskell-users] on event := doesn't work after cycling through windows

[minh t. <no...@gm...>]

hi all,

i've something like this

WX.set tFrame [    layout   :=3D fill $ widget tCanvas
                 , on paintRaw :=3D display renderingFunc tCanvas
                 , on (charKey 'p') :=3D putChar 'p'
                 ]

where the tCanvas is an OpenGL canvas.

the window is open, the opengl rendering is done. when I hit the 'p'
key, it displays it on the console, it's fine.

but if I left (by clicking on another window (not a wx one)) the
opengl window and go back to my wx opengl window, hitting the 'p' key
doesn't do anything.

why ? what must I do to correct that ?

thanks a lot,
vo minh thu
