Login.py

Question

我想在login.py中将self.user = QtGui.QLineEdit（MainWindow）变量传递给ingooi.py中的officer = str（self.tocomb.currentText（））

我的3个GUI窗口

我的程序包含各种文件，我可以根据需要从其他文件导入类。

3个主要文件包括：

Login.py（用户登录的我的登录窗口）
page22.py（用户选择输入/查看数据）
ingooi.py（用户输入数据然后通过提交将数据添加到访问数据库按钮

请参阅以下3个主要文件的代码。

    import sys
    app = QtGui.QApplication(sys.argv)
    MainWindow = QtGui.QMainWindow()
    ui = Ui_NextPage()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

问题在于你的设计，你不应该认为每个文件都是不同的程序，它实际上只有一个。

另一个建议是你不要修改QtDesigner生成的代码，如果你想在GUI中修改某些内容就会删除以上内容，这也是不必要的，例如你有一个设计，例如Login.py ：

class Ui_Logged(object):
    def setupUi(self, MainWindow):
      [...]

然后你必须创建另一个实现逻辑的类

class Login(QtGui.QMainWindow, Login.Ui_Logged):
    def __init__(self, *args, **kwargs):
        QtGui.QMainWindow.__init__(self, *args, **kwargs)
        self.setupUi(self)
        [...]

然后在你的情况下，你必须Page1()成员，并在你致电WW()时显示它，你不应该只是打开它

class Login(QtGui.QMainWindow, Login.Ui_Logged):
    def __init__(self, *args, **kwargs):
        QtGui.QMainWindow.__init__(self, *args, **kwargs)
        self.setupUi(self)
        self.Login_button.clicked(self.slot1)
        self.window = Page1()

    def WW(self):
        self.window.show()
        self.hide()

你需要在每个插槽的Page1()中做同样的事情。 NextPage()是实现Ui_NextPage()

逻辑的类

class Page1(QtGui.QMainWindow, Page22.Ui_Page1)
    def __init__(self, *args, **kwargs):
        QtGui.QMainWindow.__init__(self, *args, **kwargs)
        self.setupUi(self)
        self.pushButton.clicked.connect(self.dataenter)
        self.pushButton_2.clicked.connect(self.dataview)
        self.pushButton_3.clicked.connect(self.Taview)
        self.pushButton_4.clicked.connect(self.exit)
        self.nextPage = NextPage()

    def dataenter(self):
        self.nextPage.show()  

        [...]

因此，如果我们有这个逻辑，那么从slot()调用来访问QComboBox很容易：

def slot1(self):
    uName = self.user.text()
    uPass = self.password.text()
    combo = self.window.nextPage.tocomb
    items = [combo.itemText(i) for i in range(combo.count())]
    if uName not in items:
        combo.addItem(uName)
    combo.setCurrentTex(uName)

我试图订购你的代码，可能有导入问题，但我认为它们应该是最小的，所以你可以修复它们，运行文件main.py.完整的代码可以在以下link找到。
