Hi,
I am tying to add some code to my event handler program so that for
example each time "button1" is selected, a new widget-base inluding
some buttons and text is added to my existing widget. Can anybody
please help me how to do that? Is this at all possible?
In this way, each time "button1" is clicked and the new part is added
to the existing widget, it becomes bigger. Same as when we add a new
row to the bottom of a table; but this row has some buttons and text
inside it.
Thank you
b.a

Hi Bennett,
I tried with sensetive and as you said, buttons and other widges don't
work in this way. But now,I got it to work and it is fine up to this
stage. Thanks.
