PyQt5将QMainWindow作为第一个窗口

Question

I am building an application in pyqt, which is called by another application with another graphical interface not built in pyqt. I have a QMainWindow, the problem is that when the boot appears behind the other application, and I do not know how to make it appear with the focus. I try to pass window type in a constructor

Qt_WindowType

But does not work

This is my class

class Foo(QMainWindow):
    def __init__(self, logger):
        super(Foo, self).__init__()
        # more code...
        self.show()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = ScanGui(logger)
    sys.exit(app.exec_())

Thx.

Depending on what you are exactly looking for I'd say to have a look in this flag:

self.setWindowFlags(Qt.WindowStaysOnTopHint)

You can also make use of Modal modality.

SetWindowModality instead of WindowStayOnTopHint, and both modal modes (Qt.WindowModal and Qt.ApplicationModal) permit other applications to be on top of your modal window.
