QT Problem

[Omid Givi]

Hi there,

I just found the solution. I have to add all the child widget in one time
while constructing the gridlayout, and then raise the correct one when
needed (clicked). It works!

One said once: 'If you have an implementation problem, just get away from
your desk. Grab a cup of coffee, and think about your vacation!'

well, I just did and it helpt! ;-)
