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

    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()"

    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?
