I am new to PySide, I want to create a multi-window application. For example, the first window will be login window, and if the login is correct then the login window should hide and the next window should appear.
How can I achieve this?
import sys
from PySide.QtGui import *
from PySide.QtCore import *
import chooseoption
class Form(QDialog):
def __init__(self, parent = None):
super(Form,self).__init__(parent)
self.usernamelabel = QLabel("Username : ")
self.passwordlabel = QLabel("Password : ")
self.username = QLineEdit()
self.password = QLineEdit()
self.okbutton = QPushButton("Login")
self.username.setPlaceholderText("Enter Username Here")
self.password.setPlaceholderText("Enter Password Here")
layout = QGridLayout()
layout.addWidget(self.usernamelabel,0,0)
layout.addWidget(self.passwordlabel,1,0)
layout.addWidget(self.username,0,1)
layout.addWidget(self.password,1,1)
layout.addWidget(self.okbutton)
self.setLayout(layout)
self.usernamelist = ['priyank','stupendo','ayaan']
self.passwordlist = ['priyank','stupendo','ayaan']
self.connect(self.okbutton, SIGNAL("clicked()"),self.loginfunction)
def loginfunction(self):
usernamestatus = False
usernameindex = -1
passwordstatus = False
passwordindex = -1
for currentusername in range(len(self.usernamelist)):
if self.passwordlist[currentusername] == self.username.text():
usernamestatus = True
usernameindex = self.usernamelist.index(self.passwordlist[currentusername])
for currentpassword in range(len(self.passwordlist)):
if self.usernamelist[currentpassword] ==self.password.text():
passwordstatus = True
passwordindex = self.passwordlist.index(self.usernamelist[currentpassword])
if usernamestatus == True and passwordstatus ==True and usernameindex == passwordindex:
w2 = chooseoption.Form1()
w2.show()
else:
self.msgBox = QMessageBox()
self.msgBox.setText("invalid!!!")
self.msgBox.exec_()
app = QApplication(sys.argv)
form = Form()
form.show()
sys.exit(app.exec_())
This is my chooseoption.py file:
import sys
from PySide.QtGui import *
from PySide.QtCore import *
class Form1(QDialog):
def __init__(self, parent = None):
super(Form1,self).__init__(parent)
self.addbutton = QPushButton("Add file in Important list")
self.removebutton = QPushButton("Remove file from Important list")
self.changeaddressbutton = QPushButton("Change Location of Important File")
layout = QHBoxLayout()
layout.addWidget(self.addbutton)
layout.addWidget(self.removebutton)
layout.addWidget(self.changeaddressbutton)
self.setLayout(layout)
The problem with this is that my second window just appears on the screen for a few milliseconds, and then disappears. How can I fix that?
code below creates three windows successively:
from PySide.QtCore import *
from PySide.QtGui import *
import sys
class W1(QWidget):
def __init__(self, parent=None):
super(W1, self).__init__(parent)
self.btn = QPushButton('Click1')
vb = QVBoxLayout()
vb.addWidget(self.btn)
self.setLayout(vb)
self.btn.clicked.connect(self.fireupWindows2)
def fireupWindows2(self):
w2 = W2()
if w2.exec_():
self.w3 = W3()
self.w3.show()
class W2(QDialog):
def __init__(self, parent=None):
super(W2, self).__init__(parent)
self.btn = QPushButton('Click2')
vb = QVBoxLayout()
vb.addWidget(self.btn)
self.setLayout(vb)
self.btn.clicked.connect(self.fireupWindows3)
def fireupWindows3(self):
self.accept()
class W3(QWidget):
def __init__(self, parent=None):
super(W3, self).__init__(parent)
self.resize(300, 300)
self.btn = QLabel('The Last Window')
vb = QVBoxLayout()
vb.addWidget(self.btn)
self.setLayout(vb)
if __name__ == "__main__":
app = QApplication(sys.argv)
w = W1()
w.show()
sys.exit(app.exec_())
Somehow I was able to solve above problem
test.py file:
import sys
from PySide.QtGui import *
from PySide.QtCore import *
import chooseoption
class Form(QDialog):
def __init__(self, parent = None):
super(Form,self).__init__(parent)
self.usernamelabel = QLabel("Username : ")
self.passwordlabel = QLabel("Password : ")
self.username = QLineEdit()
self.password = QLineEdit()
self.okbutton = QPushButton("Login")
self.username.setPlaceholderText("Enter Username Here")
self.password.setPlaceholderText("Enter Password Here")
layout = QGridLayout()
layout.addWidget(self.usernamelabel,0,0)
layout.addWidget(self.passwordlabel,1,0)
layout.addWidget(self.username,0,1)
layout.addWidget(self.password,1,1)
layout.addWidget(self.okbutton)
self.setLayout(layout)
self.usernamelist = ['priyank','stupendo','ayaan']
self.passwordlist = ['priyank','stupendo','ayaan']
self.connect(self.okbutton, SIGNAL("clicked()"),self.loginfunction)
def loginfunction(self):
usernamestatus = False
usernameindex = -1
passwordstatus = False
passwordindex = -1
for currentusername in range(len(self.usernamelist)):
if self.passwordlist[currentusername] == self.username.text():
usernamestatus = True
usernameindex = self.usernamelist.index(self.passwordlist[currentusername])
for currentpassword in range(len(self.passwordlist)):
if self.usernamelist[currentpassword] ==self.password.text():
passwordstatus = True
passwordindex = self.passwordlist.index(self.usernamelist[currentpassword])
if usernamestatus == True and passwordstatus ==True and usernameindex == passwordindex:
self.hide()
w2 = chooseoption.Form1(self)
w2.show()
else:
self.msgBox = QMessageBox()
self.msgBox.setText("Bloody Hacker!!!")
self.msgBox.exec_()
app = QApplication(sys.argv)
form = Form()
form.show()
sys.exit(app.exec_())
and this is a second window :
import sys
from PySide.QtGui import *
from PySide.QtCore import *
class Form1(QDialog):
def __init__(self, parent = None):
super(Form1,self).__init__(parent)
self.addbutton = QPushButton("Add file in Important list")
self.removebutton = QPushButton("Remove file from Important list")
self.changeaddressbutton = QPushButton("Change Location of Important File")
layout = QVBoxLayout()
layout.addWidget(self.addbutton)
layout.addWidget(self.removebutton)
layout.addWidget(self.changeaddressbutton)
self.setLayout(layout)
the important part is to hide the first window and create a object of second window with self as a parameter and then show second window
self.hide()
w2 = chooseoption.Form1(self)
w2.show()

how to change item in every subwindow?
how to change text table in subwindow i want with over 10 subwindow?
Right now your label3 is stored in MainWindow, so when you cycle through your subwindows you just change the latest label. You can store it in each subwindow like this:
import sys
from PyQt5.QtWidgets import *
from PyQt5 import QtWidgets
class MainWindow(QtWidgets.QMainWindow):
count = 0
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.mdi = QMdiArea()
self.setCentralWidget(self.mdi)
bar = self.menuBar()
file = bar.addMenu("Subwindow")
file.addAction("New")
file.addAction("Change Text")
file.triggered[QAction].connect(self.click)
self.setWindowTitle("Multiple window using MDI")
def click(self, action):
print("New sub window")
if action.text() == "New":
MainWindow.count = MainWindow.count + 1
sub = QMdiSubWindow()
sub.setWidget(QTextEdit())
sub.setWindowTitle("subwindow" + str(MainWindow.count))
self.subwindow = self.mdi.addSubWindow(sub)
self.subwindow.show()
# change current subwindow label text
button = QPushButton("Click to change", sub)
button.clicked.connect(lambda: sub.label3.setText('TRUE'))
sub.label3 = QtWidgets.QLabel(sub)
sub.label3.setGeometry(10, 80, 500, 10)
sub.label3.setText('Default')
sub_layout = self.subwindow.layout()
sub_layout.addWidget(sub.label3)
sub_layout.addWidget(button)
if action.text() == "Change Text":
for i in self.mdi.subWindowList():
label1 = QtWidgets.QLabel(i)
label1.setGeometry(10, 50, 500, 10)
label1.setText(str(i))
label1.show()
i.label3.setText('TRUE')
print(i)
def main():
app = QApplication(sys.argv)
ex = MainWindow()
ex.show()
sys.exit(app.exec_())
if __name__ == '__main__':

I do not understand what you tried when writing the following:
class SaveWorker(QtCore.QObject):
progress_update = QtCore.Signal(int)
def save_file(self):
while True:
MyCustomWidget().updateProgressBar()
updateProgressBar requires a value what value are you going through?, on the other hand when using MyCustomWidget() you are creating an object different from the one shown, and no MyCustomWidget object should be created in another thread.
What you have to do is move the heavy task to the save_file method since it will be executed in another thread:
import sys
import threading
from pyface.qt import QtGui, QtCore
X, Y = 5, 4
class SaveWorker(QtCore.QObject):
progressChanged = QtCore.Signal(int)
def save_file(self):
fileList = []
processes = []
_dataSavingPer = 30.0/(X*Y)
progress = 0
for i in range(X*Y):
name = 'file'+str(i+1) + ".txt"
fileList.append(name)
progress += _dataSavingPer
self.progressChanged.emit(progress)
_dataProcessPer = 60.0/(X*Y)
for file in fileList:
process = 'fileProcess'+str(i+1) + ".txt"
processes.append(process)
progress += _dataProcessPer
self.progressChanged.emit(progress)

I m trying to resize a table widget inside a QVBoxlayout which I further add as a row to a QFormlayout in pyqt
I m currently adding a QVboxlayout which contains a table widget inside it as a row in a Qformlayout.
And the main aim is to strecth the Table widget till the end of the application window that it acquires the left over space on the window
Using the below code -
class PGSearchDetails():
def __init__(self,parent=None):
self.widget_pgsd = QWidget()
self.layout_pgsd = QFormLayout()
self.layout_pgsd.setFieldGrowthPolicy(QFormLayout.FieldGrowthPolicy(2|1))
self.PG_Id = QLineEdit()
#rx = QRegExp("^\\D+[!,#,#,$,%,\^,&,*,(,),:,\",{,},?,<,>,|,+,-,~,]")
#rx = QRegExp(" (?!(#,#,$|%|\^|&|*|(|)|:|\"|{|}|?|<|>|\||+|-|~|!))[\\w]+")
str_rx = QRegExp("^[A-Za-z*]{20}(?!##$%^&*():\"\{\}?<>\|+-~!_-)")
adhr_rx = QRegExp("[A-Z0-9]{12}(?!##$%^&*():\"\{\}?<>\|+-~!_)")
val = QRegExpValidator(str_rx)
val3 = QRegExpValidator(adhr_rx)
self.PG_Id.setValidator(val3)
self.LastName = QLineEdit()
self.LastName.setValidator(val)
self.MobNum = QLineEdit()
qint_val = QIntValidator()
qint_val.setTop(10)
self.MobNum.setValidator(qint_val)
self.layout_pgsd.addRow("First Name",self.PG_Id)
self.layout_pgsd.addRow("Last Name",self.LastName)
self.layout_pgsd.addRow("Mobile Number",self.MobNum)
update_layout_pgsd = QHBoxLayout()
layout_test,table = dbv.Search_View(self.getT)
#layout_test.setGeometry(QRect(200,200,50,50))
#table.setMaximumHeight(800)
#table.setGeometry(200,200,200,200)
#table.setGeometry(1,1,1000,600)
table.resize(1000,600)
update_btn_pgsd = QPushButton('Update')
reset_btn_pgsd = QPushButton('Reset')
update_layout_pgsd.addWidget(update_btn_pgsd)
update_layout_pgsd.addWidget(reset_btn_pgsd)
self.layout_pgsd.addRow(update_layout_pgsd)
##Adding the Table Widget to FormLayot
self.layout_pgsd.addRow(layout_test)
update_btn_pgsd.clicked.connect(partial(self.database,table,self.MobNum,
self.LastName))
#self.widget.setLayout(self.layout_pgsd)
def returnLayout(self):
return self.layout_pgsd
def returnWidget(self):
return self.widget_pgsd
def getT(self,linedit):
print("LE--->",linedit.text())
QtableWidget setup ---
def Search_View(self):
print("Inside Search_view")
central_widget = QWidget() # Create a central widget
db_layout = QVBoxLayout()
#col_count = len(self.pg_details.__dict__.keys())
col_count = 3
table = QTableWidget() # Create a table
#central_widget.setGeometry(200,200,150,150)
#table.maximumSize()
#db_layout.setMaximumSize(200)
db_layout.setGeometry(QRect(0,0,100,30))
db_layout.addWidget(table)
##Tried resizing the Table widget but nothing seems to works
table.resize(1000,600)
table.setGeometry(0,2,1000,600)
#central_widget.resize(central_widget.sizeHint())
#central_widget.setColumnWidth(1000,600)
#db_layout.addItem(update_layout)
central_widget.setLayout(db_layout)
print("Geometry H--->",table.geometry().height())
print("Geometry W--->",table.geometry().width())
print("Geometry X--->",table.geometry().x())
print("Geometry Y--->",table.geometry().y())
return central_widget,table
After the resize function, The table geometry changes to 1000,600 but on the screen it is not reflected. On the app screen it remains the same size everytime
Also find the entire code which contains the Tablayouts as well and Stacked widget for individual radio buttons

self.tab1.setLayout(self.central_layout)
def SelectButtonCheck(self,b):
if b.text() == "Search":
if b.isChecked():
print(b.text()+ "is selected")
self.obj_pgsd = pgsd.PGSearchDetails()
layout = self.obj_pgsd.returnLayout()
if self.stack1.layout() is None:
self.stack1.setLayout(layout)
self.stack_widget.setCurrentIndex(0)
def main():
application = QApplication(sys.argv)
main_window = MainTabWindow()
main_window.show()
sys.exit(application.exec_())
if __name__ == '__main__':
main()
I do not seem to understand what is I m missing here
Any pointers would be appreciated.
Also find the working code to execute the above layout setup.

The problem is that QFormLayout makes every time you add a widget using addRow () uses strech, the solution is to use a QVBoxLayout, and in that QVBoxLayout is to pass the QFormLayout and the layout_test.
class PGSearchDetails():
def __init__(self,parent=None):
self.widget_pgsd = QWidget()
self.layout = QVBoxLayout() # <---
self.layout_pgsd = QFormLayout()
self.layout.addLayout(self.layout_pgsd) # <---
self.layout_pgsd.setFieldGrowthPolicy(QFormLayout.FieldGrowthPolicy(2|1))
...
self.layout_pgsd.addRow(update_layout_pgsd)
##Adding the Table Widget to FormLayot
# self.layout_pgsd.addRow(layout_test)
self.layout.addWidget(layout_test) # <---
update_btn_pgsd.clicked.connect(partial(self.database,table,self.MobNum,
self.LastName))
def returnLayout(self):
return self.layout # <---
I am trying to write a code which allows me to present one questions per page (without opening new windows). I wanted to know how i could alter the code below to allow me to do this??
import sys
from PyQt4 import QtCore, QtGui
class StartTest(QtGui.QMainWindow):
def __init__(self, parent=None):
super(StartTest, self).__init__(parent)
self.central_widget = QtGui.QStackedWidget()
self.setCentralWidget(self.central_widget)
QPage = Question(self)
self.central_widget.addWidget(QPage)
self.central_widget.setCurrentWidget(QPage)
class Question(QtGui.QWidget):
def __init__(self, label, parent=None):
super(Question, self).__init__(parent)
label = question1
question = QtGui.QLabel(label)
self.proceed = QtGui.QPushButton('Proceed')
self.Answer = QtGui.QLineEdit(self)
layout = QtGui.QFormLayout()
layout.addRow(question, self.Answer)
layout2 = QtGui.QVBoxLayout()
layout2.addLayout(layout)
layout2.addWidget(self.proceed)
self.setLayout(layout2)
self.proceed.clicked.connect(self.nextQ)
def nextQ(self):
Answer = self.Answer.text()
studentAns.append(Answer)
label = question2
studentAns = []
question1 = 'What is 5+5?'
question2 = 'What is 45+10?'
if __name__ == '__main__':
User = ''
app = QtGui.QApplication([])

This should give you an idea of how to structure your program:

self.stack.addWidget(page)
self.answers = []
def handleSubmit(self, index):
page = self.stack.widget(index)
answer = page.answer.text()
# validate submitted answer...
self.answers.append(answer)
if index < self.stack.count() - 1:
self.stack.setCurrentIndex(index + 1)
class Question(QtGui.QWidget):
def __init__(self, question, parent=None):
super(Question, self).__init__(parent)
self.question = QtGui.QLabel(question, self)
self.answer = QtGui.QLineEdit(self)
self.submit = QtGui.QPushButton('Submit', self)
form = QtGui.QFormLayout()
form.addRow(self.question, self.answer)
layout = QtGui.QVBoxLayout(self)
layout.addLayout(form)
layout.addWidget(self.submit)
if __name__ == '__main__':
User = ''
app = QtGui.QApplication([])
questions = [
'What is 5+5?',
'What is 45+10?',
'What is 28+47?',
'What is 22+13?',
]
window = StartTest(questions)
window.showFullScreen()
app.exec_()
