Question

我刚刚开始使用Python编程，就像几周前一样。几天后，我开始使用一些PyQt教程，现在我遇到了一些问题。

所以我有一个带有菜单栏的窗口。就像Windows资源管理器一样，例如“文件”，子菜单带“退出”。

我想要的是每个按钮在窗口中显示不同的文本。就这样。所以现在当我点击一个按钮时，它会转到def并在交互式Python shell上打印一些内容。

def button1(self):
    print('Button clicked.')

但我想要的是它在窗口中显示tekst。

如果需要，填写完整的代码

    def close_application(self):
    # deze method wordt toegepast op de 1e instance, in dit geval self.
        choice = QMessageBox.question(self, 'message',
                                        "Nooo! R u sure?", QMessageBox.Yes |
                                        QMessageBox.No, QMessageBox.No)

        if choice == QMessageBox.Yes:
            print('quit application')
            sys.exit()
        else:
            pass

    def intermaris_algemeen(self):
        print('Button clicked.')



    def run():
    app = QApplication(sys.argv)
    Gui = window()
    sys.exit(app.exec_())

    run()

Answer 1

替换print('Button clicked.') 与self.label.setText('Button clicked.') 然后点击“按钮点击”。文本将出现而不是'Dit is het control center van Andre Jochemsen';

单击按钮后显示文本的PyQt
