Hi mysota,
I had actually used the "calculatorform" you suggested as a guide for my program
In the example, Items change from within the designer as a result of a user action on an item.

I have a row of 12 "PushButtons" and a row of 12 labels (F1....F12)
The labels on the buttons change as the program progresses.

In my program the user has to click on a button, press a keyboard function key or enter an accelerator letter to do anything.

So, I need to know in my calculatorform.cpp which button was clicked. (function keys and accelerator letters aren't any problem).

I have looked at other examples and i haven't found this condition addressed.

I know this approach is not standard, but neither is my program.
To better understand what I'm trying to do look at "Qcad" . Instead of Icons, I have push buttons across the bottom of the screen to perform the same type of function.

thanks
