Hi

Suppose i have w (a QWidget) and W (a QMainWindow).
This means i have a w.h+w.cpp+w.ui and W.h, W.cpp and W.ui, as well as the rest of the project files.

How can i use the w widget as the W central widget, as well as keep changing from w to other similar widgets (... x, y, z , ...)?
Does this apply to QDialogs instead of QWidgets as well?

Summarizing, i want to write several QDialogs or QWidgets and show them inside a QMainWindow, one at a time, in it's central widget.

Thanks
