Hi,
I am new to python. I am developing an application in python using PyQt4. I want a multipage application. I wrote one code this I need help how can I code when I press the next button on the first page it should go to the next page with different widgets.
import sys
from PyQt4 import QtGui, QtCore
class Window(QtGui.QMainWindow):
def __init__(self):
super(Window, self).__init__()
self.setGeometry(0, 0, 800, 480)
self.setWindowTitle("Femikare")
self.home()
def home(self):
label1 = QtGui.QLabel(self)
label1.setText("Please Select One Product")
label1.setStyleSheet("font: bold 50px;" "color: rgb(255, 0, 127);" "background-color: white;" "qproperty-alignment: AlignCenter;")
label1.resize(800,40)
label1.move(0,0)
#qApp->setStyleSheet("QRadioButton { background-color: white; background-position: center}");
rdoProduct = QtGui.QRadioButton(self)
rdoProduct.setIcon(QtGui.QIcon("images/1.png"))
rdoProduct.setIconSize(QtCore.QSize(180,180))
rdoProduct.productId = "1"
rdoProduct.toggled.connect(self.test)
rdoProduct.resize(200,200)
rdoProduct.move(0,40)
rdoProduct.setStyleSheet('QRadioButton::unchecked{background-color: white; width: 0px; height: 0px;}' 'QRadioButton::checked{background-color: pink; width: 0px; height: 0px;}' 'QRadioButton::indicator{width: 0px; height: 0px;}')

Thank you alfalfa. You provided me a PyQt5 creator snippet but I am writing directly in python so if I can find some example in python itself then it would be great.

Here is an in-code example of using a Stacked-Widget. I used it to help show someone how to keep a button from one page to the next and how to pass information between pages but it has the basics for the usage of a stacked widget

Here is the same example, but with the ui file translated to python. It is generated by uic so you might want to clean it up a bit.

self.ui.setupUi(self)
self.ui.listWidget.itemSelectionChanged.connect(self._pageUpdate)
self.show()
def _pageUpdate(self):
index = self.ui.listWidget.currentRow()
self.ui.stackedWidget.setCurrentIndex(index)
if __name__== '__main__':
app = QtWidgets.QApplication([])
gui = Main()
sys.exit(app.exec_())gui.py

Hello, thank you for your reply it helped me. I wrote my code like this, not exactly but like this structure.
import sys
from PyQt5.QtCore import *
from PyQt5.QtGui import *
class stackedExample(QWidget):
def __init__(self):
super(stackedExample, self).__init__()
self.leftlist = QListWidget ()
self.leftlist.insertItem (0, 'Contact' )
self.leftlist.insertItem (1, 'Personal' )
self.leftlist.insertItem (2, 'Educational' )
self.stack1 = QWidget()
self.stack2 = QWidget()
self.stack3 = QWidget()
self.stack1UI()
self.stack2UI()
self.stack3UI()
self.Stack = QStackedWidget (self)
self.Stack.addWidget (self.stack1)
self.Stack.addWidget (self.stack2)
self.Stack.addWidget (self.stack3)
hbox = QHBoxLayout(self)
hbox.addWidget(self.leftlist)
hbox.addWidget(self.Stack)
self.setLayout(hbox)
self.leftlist.currentRowChanged.connect(self.display)
self.setGeometry(300, 50, 10,10)
self.setWindowTitle('StackedWidget demo')
self.show()
def stack1UI(self):
layout = QFormLayout()
layout.addRow("Name",QLineEdit())
layout.addRow("Address",QLineEdit())
#self.setTabText(0,"Contact Details")
self.stack1.setLayout(layout)
def stack2UI(self):
layout = QFormLayout()
sex = QHBoxLayout()
sex.addWidget(QRadioButton("Male"))
sex.addWidget(QRadioButton("Female"))
layout.addRow(QLabel("Sex"),sex)
layout.addRow("Date of Birth",QLineEdit())
self.stack2.setLayout(layout)
def stack3UI(self):
layout = QHBoxLayout()
layout.addWidget(QLabel("subjects"))
layout.addWidget(QCheckBox("Physics"))
layout.addWidget(QCheckBox("Maths"))
self.stack3.setLayout(layout)
def display(self,i):
self.Stack.setCurrentIndex(i)
def main():
app = QApplication(sys.argv)
ex = stackedExample()
sys.exit(app.exec_())
if __name__ == '__main__':
main()Now I want to pass a variable value from one window to another window so I can use that value there. For example, if I have a variable x = 10 in stack1UI, I want to pass this x value to stack2UI and want to do y = x*10.

Change this :
self.stack1UI()
self.stack2UI()
self.stack3UI()To this:
self.stack1UI(self)
self.stack2UI(self)
self.stack3UI(self)Add this:
def stack1UI(self, parent):
self.Parent = parentThen all you have to do is:
self.Parent.Value = X Or if your Parent needs to adjust its child
self.Stack1.Value = X Those QWidgets would have however been better handled by making each one their own Class
def stack1UI(QWidget):
def __init__(self, parent):
QWidget.__init__(self)
