Varolan bir python3 ve Qt4 kullanarak yeni bir pencere aramaya çalışıyorum.Varolan bir pencereden yeni PyQt4 pencereleri nasıl oluşturulur?
Qt Designer (ana uygulama ve bir diğeri) kullanarak iki pencere oluşturdum ve Qt Designer tarafından oluşturulan .ui dosyalarını .py komut dosyalarına dönüştürdüm - ancak yeni pencereler oluşturamıyorum ana uygulamadan.
bunu yaparken çalıştı:############### MAIN APPLICATION SCRIPT ################
from PyQt4 import QtCore, QtGui
import v2
try:
_fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
_fromUtf8 = lambda s: s
class Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName(_fromUtf8("Form"))
Form.resize(194, 101)
self.button1 = QtGui.QPushButton(Form)
self.button1.setGeometry(QtCore.QRect(50, 30, 99, 23))
self.button1.setObjectName(_fromUtf8("button1"))
self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
Form.setWindowTitle(QtGui.QApplication.translate("Form", "Form", None, QtGui.QApplication.UnicodeUTF8))
self.button1.setText(QtGui.QApplication.translate("Form", "Ventana", None, QtGui.QApplication.UnicodeUTF8))
self.button1.connect(self.button1, QtCore.SIGNAL(_fromUtf8("clicked()")), self.mbutton1)
def mbutton1(self):
v2.main()
if __name__ == "__main__":
import sys
app = QtGui.QApplication(sys.argv)
Form = QtGui.QWidget()
ui = Ui_Form()
ui.setupUi(Form)
Form.show()
sys.exit(app.exec_())

Ama bu hata mesajı alıyorum:
