使一个窗口出现在另一个窗口的上方，禁止访问其他窗口，直到单击按钮

Question

Python 2.7, PyQt4.8.5

I want to have a main app window and then a second pop up window to display com port settings. This window should always be on top of the parent window until either the ok or the cancel button is clicked; closing the child window. (sort of like a required answer ie cant process until you choose the settings from the child window)

Is there a Python Qt command to do this?

Apologies if this has been asked/answered before, my search returned nothing useful.

Answer 1

You want a modal dialog. For example:

dialog = QInputDialog()
dialog.exec_()

You can either implement your own dialog widget (by subclassing QDialog ) or use one of the several available.
