Question

指出：

我开始学习pyqt并通过qt desiger使用pyqt4。我打算做一些测试项目并将其导出为.py文件。可悲的是，当我运行脚本时没有显示任何内容，我想这是因为脚本没有.show()命令所以所有内容都“打印”在内存中但它永远不会显示。可悲的是，我无法弄清楚应该把它放在哪里让事情发挥作用。

代码：

Answer 1

如果你想使用导出为python文件的Qt Designer文件，你应该导入该文件，然后你可以按如下方式使用它：

from yourfilename import Ui_MainWindow

ui = Ui_MainWindow()
ui.setupUi()  # needed to setup the ui you defined in the designer
ui.show()

您还可以使用自己的子类扩展Ui_MainWindow类。在这种情况下，您需要调用类似self.setupUi(self)的内容。

Answer 2

你应该可以将它添加到你的班级：

class Ui_MainWindow(object):
    def __init__(self):
        self.setupUi()
        self.show()

当在下面的语句中初始化类时，将调用此方法。此代码应低于您的所有代码。

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    window = Ui_MainWindow()
    sys.exit(app.exec_())

执行脚本时会自动调用此方法。

pyqt，qt designer .show（）;无法弄清楚如何展示我的gui
