Question

我正在开发一个项目，我想为此开发GUI。我用Qt Designer创建了4个不同的UI文件，并用PySide（pyside-uic）将它们转换成python文件。现在，我想创建一个主python文件来连接这些窗口。我的软件结构如下：

1 - 欢迎窗口：按下按钮加载主窗口并关闭欢迎窗口 2 - 主窗口：它有2个按钮可以打开我的第三个和第四个窗口。

我已阅读this post和this one帖子，但我无法完成（我是新手）。

这是我欢迎窗口的代码：

</nav>

这是我的主窗口：

        self.verticalLayout_2 = QtGui.QVBoxLayout(welcome_window)

        self.verticalLayout_2.addWidget(self.welcomeBTN)

        self.retranslateUi(welcome_window)
        QtCore.QObject.connect(self.welcomeBTN, QtCore.SIGNAL("clicked()"), welcome_window.close)
        QtCore.QMetaObject.connectSlotsByName(welcome_window)

    def retranslateUi(self, welcome_window):
        welcome_window.setWindowTitle(QtGui.QApplication.translate("welcome_window", "Welcome", None, QtGui.QApplication.UnicodeUTF8))
        self.welcomeLBL.setText(QtGui.QApplication.translate("welcome_window", "Welcome TO the Software", None, QtGui.QApplication.UnicodeUTF8))
        self.welcomeBTN.setText(QtGui.QApplication.translate("welcome_window", "Enter to Software", None, QtGui.QApplication.UnicodeUTF8))


if __name__ == "__main__":
    import sys
    app = QtGui.QApplication(sys.argv)
    welcome_window = QtGui.QWidget()
    ui = Ui_welcome_window()
    ui.setupUi(welcome_window)
    welcome_window.show()
    sys.exit(app.exec_())

有没有办法在主Python代码中调用这些类？

感谢。

Answer 1

您只需在主文件中导入它们即可：

from first_file import Ui_welcome_window
from second_file import Ui_main_window

然后你可以像往常一样从那里使用它们（注意，未执行2个文件中的if __name__ == "__main__"部分）

制作按钮：

#create the 2 windows
main_window = QtGui.QWidget()
ui = Ui_main_window()
ui.setupUi(main_window)

welcome_window = QtGui.QWidget()
ui2 = Ui_welcome_window()
ui2.setupUi(welcome_window)

ui2.welcomeBTN.clicked.connect(main_window.show)

当您单击welcome_window上的Button时，main_window应为show()。对第3和第4窗口做同样的事情！

问候，MrP01
