How to launch a dialog?

[franz]

How would I launch this new dialog from a button press? Do I have to do it in C++?

Yes. You also need to define behavior for your newly designed dialog, so you'll be making a class that uses the generated header file. Non-modal showing of windows can be done using QWidget::show().

It sounds like I'd also have to send signals from the child window to slots in the main window in C++, and can't do it in QTDesigner.
