[PyQt] Re: [Matplotlib-users] Strange issue when using Matplotlib with PyQt4

[Lukas Hetzenecker]

Hm.. I added a resize() after the show():

class Plot_tab(QTabWidget, tab):
    def __init__(self):
        super(Plot_tab, self).__init__()
        self.setupUi(self)

        self.show()
        self.resize(self.size().width()+1, self.size().height()+1)
        self.resize(self.size().width()-1, self.size().height()-1)

if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)

    plot_t = Plot_tab()

    sys.exit(app.exec_())


Now it works, but I really want to know why..?
Is there a way to avoid this ugly workaround?

Thanks,
Lukas
