View Full Version : How to communicate between two forms

7th April 2009, 08:54
Hi friends,

I am trying to do a C IDE using QT 3.3 . Can I communicate between two forms. I want to send a signal to one form when user clicked a pushbutton in other form. If that is not possible can I connect the destruction of one form to other form . What i meant is that a function should exicute in one form when other form is destroyed. I think I have given enough details (my english is not that good). Hope anyone can help me.

create two seperate classes that accesses these forms..in the destructor of one class, call the function u r looking to execute..

Thanks talk2amulya for the quick reply.. but I didnt understand what you are saying . What I understood that I have to create two more classes (I already have two , one for each form). Each of these new classes can access both the parent classes. So totally I have 4 classes and I have to work with my new classes rather than the old two. Is my reasoning is correct ?

Note : In the meantime I somewhat achieved my needs using an extern variable(flag is the correct word) and a QTimer which checks for these flag every 0.1 seconds. Not good c++ style of thinking but it seems to be working..
