hi all

initially a window contains a button name as orgin,
if we click the "origin"
a button should be create in table(X,Y)
and again
if we click on the "origin"
second button should be create in the same table(X,Y).
like this we should create 10 to 20 buttons in that table.

and every new created button should have a signal.
EX:
if we click on the 1st button it should print "this is the 1st button".....
....
like that

is there any way to do this.

any help it should be appreciable.

I don't really understand what you want to accomplish, do you want to have a button created and packed where you click?
