Layout won`t work at execution pyqt
In pyqt4 designer I created UI and set layouts here is my code generated by
pyuic4
in python:

`
and my main code :
import sys
from PyQt4.QtGui import *
from PyQt4 import QtCore, QtGui, uic
#from PyQt4.QtWidgets import *
from PyQt4.QtCore import *
from do import Ui_Dialog
class MyApp(QtGui.QMainWindow, Ui_Dialog):
def __init__(self, parent = None):
super(self.__class__, self).__init__()
QtGui.QMainWindow.__init__(self, parent)
central_widget = QtGui.QWidget()
self.setCentralWidget(central_widget)
self.ui = Ui_Dialog()
self.ui.setupUi(central_widget)
self.setupUi(self)
self.OK.clicked.connect(lambda: self.handleButton)
QtGui.QMainWindow.__init__(self)
Ui_Dialog.__init__(self)
self.ui.setupUi(self)
def handleButton(self):
nume = ""
prenume = ""
mail = ""
varsta = ""
nume = self.line_nume.text()
prenume = self.line_prenume.text()
mail = self.line_mail.text()
varsta = self.spin.get()
print(nume, prenume, mail)
def initUi(self):
nume = QtGui.QLabel('Nume')
prenume = QtGui.QLabel('Prenume')
review = QtGui.QLabel('Review')
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
window = MyApp()
window.show()
sys.exit(app.exec_())
`
at execution appears a window with button OK on top left and a lineEdit under button, how to fix it ?
Solution
If one of the 5 templates is used you must use the correct widget, in your case I think you have used the Dialog without buttons template, so the widget to use must be QDialog, not QMainWindow, you must also invoke the widget's constructor and call to the setupUi() method of the design:
import sys
from PyQt4 import QtCore, QtGui
from do import Ui_Dialog
class MyApp(QtGui.QDialog, Ui_Dialog):
def __init__(self, parent = None):
QtGui.QDialog.__init__(self, parent)
self.setupUi(self)
self.OK.clicked.connect(self.handleButton)
def handleButton(self):
nume = ""
prenume = ""
mail = ""
varsta = ""
nume = self.line_nume.text()
prenume = self.line_prenume.text()
mail = self.line_mail.text()
varsta = self.spin.value()
print(nume, prenume, mail, varsta)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
window = MyApp()
window.show()
sys.exit(app.exec_())
