PyQT copy text from form1 to form2

Printable View

Dear Friends. I wrote a program that have Form and Form2 called V1. V1 will show after cliked button in Form1.
In V1 I have a LineEdit and button. When i wrote something in LineEdit in V1 I want send this text to LineEdit in Form1.

Code:

from PyQt4 import QtCore, QtGui
from V1 import Ui_V1
 
 
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())
 
 
 
 
# 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))
        self.label_6.setObjectName(_fromUtf8("label_6"))...
 
 
    def retranslateUi(self, Form):
        Form.setWindowTitle(_translate("Form", "Form", None))
        self.label_6.setText(_translate("Form", "<html><head/><body><p><span style=\" font-size:16pt; font-weight:600;\">TYGODNIOWA KONTROLA JAKOSCI</span></p></body></html>", None))
        self.label_8.setText(_translate("Form", "(dd-mm-rrrr)", None))...
 
        self.pushButton_2.clicked.connect(lambda: self.zapis_tyg()) # Do zapisu do tyg formularza
        self.pushButton_5.clicked.connect(lambda: self.openV1())  # v1 window
 
 
    #zapis do pliku formularza tyg
    def zapis_tyg(self): # ZAPIS DO FORMULARZ TYGODNIOWEGO
         s = ""
         seq = (self.comboBox_6.currentText(), ".txt"); # This is sequence of strings. laczenie aby nazywaÅ‚ pliki wzaleznosci od aparatu
         a= s.join( seq )
         text_file = open( a , "a")
         text_file.write(self.lineEdit.text()+ "\t" ) #data
         text_file.write(self.lineEdit_2.text()+ "\t" ) #osoba
         text_file.write(self.comboBox_6.currentText() + "\t" ) #aparat
         text_file.write(self.comboBox.currentText() + "\t" ) #AKCESORIUM
         text_file.write(self.comboBox_2.currentText() + "\t" ) #ZAB ANTYK
         text_file.write(self.comboBox_3.currentText() + "\t" ) #iZO
         text_file.write(self.comboBox_4.currentText() + "\t" )# CENTRQTOR
         text_file.write(self.comboBox_5.currentText() + "\t" )# TELEMETR
         text_file.write(self.textEdit.toPlainText()+ "\n" ) # KOM MECH
         text_file.close()
 
    #function to show a new form
    def openV1(self):
        self.V1Window=QtGui.QMainWindow()
        self.ui= Ui_V1()
        self.ui.setupUi(self.V1Window)
        self.V1Window.show()

I had an error:

'Ui_V1' object has no attribute 'Ui_Form'
Where is the problem?
Thank you

Re: PyQT copy text from form1 to form2

First, this looks like you have edited the generated class instead of just using it.

Second, as Python tells you, your Ui_V1 class does not have any member called Ui_Form.

Re: PyQT copy text from form1 to form2
If you want to access "self.Ui_Form" then you need to initizalize this.

Something like
Code:

self.Ui_Form = Ui_Form()

Re: PyQT copy text from form1 to form2

Ok so I have done it :

Quote:

def wyslij(self):
self.kopiaWindow=QtGui.QMainWindow()
self.Ui_Form=Ui_Form()
self.Ui_Form.lineEdit.text()=self.lineEdit.text()

and i have an error:

Quote:

SyntaxError: can't assign to function call

thanks.

Re: PyQT copy text from form1 to form2

Yes, last line of your new code.

You are trying to assign to the function text()
You probably want to assign to the property text instead.

Re: PyQT copy text from form1 to form2

Either by assiging to the target's text property or by calling the target's setText function.

Re: PyQT copy text from form1 to form2

could you show me an example how to do this?
Thanks

something like this?

Quote:

self.Ui_Form.lineEdit.text(self.lineEdit.text())

Error:

Quote:

AttributeError: 'Ui_Form' object has no attribute 'lineEdit'

This error is showing when I paste V1 class in MainFile.py but when I separate in two files (of course with import V1/Import MainFile)

Quote:

self.Ui_Form=Ui_Form()
NameError: name 'Ui_Form' is not defined

thanks

Maybe you should consider doing a Python tutorial first if you are unclear about assignments or method calls.

No, QLineEdit does not have a method called "text" that also has arguments.
Why would you even try that?

Which is a different error all together, you are trying to access an object that doesn't exist.
Python is sometimes doing things that are automagically correct, but even Python can't magically create objects.
