PyQt4在.py文件之间共享QLineEdit变量
[英]PyQt4 sharing QLineEdit variable across .py files
问题描述
我想将Login.py中的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，可根据需要从其他文件中导入类。
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”按钮添加数据以访问数据库
请在下面查看这3个主要文件的代码。
Login.py

问题出在您的设计中，您不应认为每个文件都是一个不同的程序，它实际上只是一个。
另一个建议是您不要修改QtDesigner生成的代码，如果您想在GUI中修改某些内容，也将擦除上面所有内容，例如，如果您有设计，例如Login.py，则也不需要这样做：
class Ui_Logged(object):
def setupUi(self, MainWindow):
[...]
然后，您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)
[...]
那么在您的情况下，您必须是该类的Page1()成员，并在调用WW()时显示它，您不应仅打开它就创建它
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()
对于每个插槽，您必须在Page1()执行相同的操作。 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，如果有这种逻辑，就可以很容易地从slot()调用QComboBox：
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)
我尝试订购您的代码，也许有导入问题，但我认为它们应该很小，以便您可以修复它们，运行文件main.py。 完整的代码可以在以下链接中找到。
