Question

I came across a pyside script demonstrating a frame, and pyside script demonstrating buttons and box layout.

I made a primitive attempt to combine the two scripts, but I can’t get both of the following functions to work at the same time: run_button_app(True) and run_frame_app(True)

One of the functions uses this statement: app_frame = QApplication([])
and the other uses this statement: app1 = QtGui.QApplication(sys.argv)
The tutorials I used did not include material explaining these things. I’ve ordered a book on Pyside and PyQt programming, but it hasn’t arrived yet.

I’m trying to figure out how to use the frame (e.g., to put a couple of frames in window, and put my buttons in one of the frames), but I haven’t been able to figure that out yet, nor where to get info (example? tutorial?) about how to use the frame.

I am a pyside and python newbie.
Any tips (e.g., links to relevant tutorials) would be much appreciated.

Thanks,
Marc

You can’t run two QAplication instances at once,
here some information in this tutorial.

I dont fully understand what are you trying to do, but if you want to add Example widget (with buttons) to FrameTester, you need to create some layout in FrameTester and add Example instance to this layout (there are many tutorials on it).

If you want Example widget to have frame, you need to subclass QFrame:

class Example(QFrame):
    def __init__(self, parent=None):
        super(Example, self).__init__(parent)
        self.setLineWidth(3)
        self.setFrameStyle(QFrame.Box|QFrame.Sunken)  
# ...    

Tip for the future, when you defining some Widget, provide parent argument to __init__ function, so it can be used in other places.
