How to make modal widget wait for input after it is shown.

[cuiqimeng]

I have a QWidget derived object, and "setWindowModality(Qt::WindowModal)" to it.
Then I call "show()", however, the process did not get blocked there, although the widget is modal indeed.

What I want is, how to make it work like "CDialog:: DoModal()" in MFC, the process will not go further until the dialog is dismissed.

maybe you need to call exec instead of show

It seems QWidget doesn't have "exec()" :(

[hashb]

according to QT document,
Qt::WindowModal only makes sense for windows,so you can use isWindow () to check whether it is a window not not, if not , show will not block

How about deriving from QDialog rather than QWidget?
