【中文标题】文本从 LineEdit1 (Form1) 到 LineEdit2 (Form2)_Python, PyQt【英文标题】：Text from LineEdit1 (Form1) to LineEdit2 (Form2)_ Python, PyQt 【发布时间】：2016-09-30 12:49:34 【问题描述】：我在主窗口中使用 LineEdit11 和 button1 创建了 MainWindow。我还使用 LineEdit 和按钮 2 创建了 V1 Form 2。
当我单击 Button1 时，Form 2 将显示。我在 lineEdit 中写了一个文本，我想通过单击 Button2 将文本传输到 form1 中的 LineEdit11。如何连接它们？
Python 3.5、PyQT 4
提前谢谢你
好的，所以我在 V1 课上写
def wyslij(self):
self.lineEdit.setText(self.Ui_Form.lineEdit_11.text())
我得到错误：
'Ui_V1' 对象没有属性 'Ui_Form' 当然，我将 V1 类添加到 Ui_Form 中。 V1是第二个窗口，Ui_Form是主窗口。
这是一个完整的代码：
from PyQt4 import QtCore, QtGui
from V1 import Ui_V1
from V2 import Ui_V2
from V3 import Ui_V3
try:
_fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
def _fromUtf8(s):
return s
try:
_encoding = QtGui.QApplication.UnicodeUTF8
def _translate(context, text, disambig):
return QtGui.QApplication.translate(context, text, disambig, _encoding)
except AttributeError:
def _translate(context, text, disambig):
return QtGui.QApplication.translate(context, text, disambig)
# V1 window
class Ui_V1(object):
def setupUi(self, V1):
V1.setObjectName(_fromUtf8("V1"))
V1.resize(400, 300)
self.label = QtGui.QLabel(V1)
...
self.pushButton.setText(_translate("V1", "Wyslij", None))
self.pushButton_2.setText(_translate("V1", "Wyslij", None))
self.pushButton.clicked.connect(lambda: self.wyslij())
def wyslij(self):
self.lineEdit.setText(self.Ui_Form.lineEdit_11.text())
# V2 okno
class Ui_V2(object):
def setupUi(self, V2):
V2.setObjectName(_fromUtf8("V2"))
V2.resize(400, 300)
self.label_4 = QtGui.QLabel(V2)
...
self.pushButton.setText(_translate("V2", "Wyslij", None))
self.label.setText(_translate("V2", "V2", None))
self.label_3.setText(_translate("V2", "A", None))
self.pushButton_2.setText(_translate("V2", "Wyslij", None))
# V3 okno
class Ui_V3(object):
def setupUi(self, V3):
V3.setObjectName(_fromUtf8("V3"))
V3.resize(400, 300)
self.label_4 = QtGui.QLabel(V3)
...
self.pushButton.setText(_translate("V3", "Wyslij", None))
self.label.setText(_translate("V3", "V3", None))
self.label_3.setText(_translate("V3", "A", None))
self.pushButton_2.setText(_translate("V3", "Wyslij", None))
# Main window!
class Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName(_fromUtf8("Form"))
Form.resize(728, 601)
Form.setMinimumSize(QtCore.QSize(728, 601))
self.label_6 = QtGui.QLabel(Form)
self.label_6.setGeometry(QtCore.QRect(169, 3, 401, 41))

def openV1(self):
self.V1Window=QtGui.QMainWindow()
self.ui= Ui_V1()
self.ui.setupUi(self.V1Window)
self.V1Window.show()
def openV2(self):
self.V2Window=QtGui.QMainWindow()
self.ui= Ui_V2()
self.ui.setupUi(self.V2Window)
self.V2Window.show()
def openV3(self):
self.V3Window=QtGui.QMainWindow()
self.ui= Ui_V3()
self.ui.setupUi(self.V3Window)
self.V3Window.show()
还有这条线：
def wyslij(self):
self.lineEdit.setText(self.Ui_Form.lineEdit_11.text())
不能正常工作。
【问题讨论】：
如果你想要一个好的答案，你应该展示一些来 【参考方案1】：没有任何代码，最简单的方法（但不是最好的）就是这样的：
def on_button2_click(self):
self.form2.lineEdit2.setText(self.lineEdit1.text())
