Re: emitting a signal for refeshing entries

[Peter Van Osta <pvosta unionbio-eu com>]

John,

Thanks for the information, but will gtk_widget_queue_draw()
cause all subelements in the window like spinbuttons to update if I do 
not capture the "draw" signal ? I use the callbacks for the "expose" 
signal to refresh the values of the spinbuttons, etc.

A parameter can vary form 1 to 100 and I want the spinbutton to show 
this value from this parameter when it changes in the program not only 
by interaction. I now how to set it from within the software, but I 
would like to ahve all callback function that react on "expose" events 
to be activated at once.

Best regards,

Peter Van Osta
