I want to get MsgBox after button click. I try to use PyQt5 for it. I make windows form with one button:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(800, 600)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(320, 330, 251, 51))
self.pushButton.setObjectName("PushButton")
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 21))
self.menubar.setObjectName("menubar")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.pushButton.setText(_translate("MainWindow", "PushButton"))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
Then I try to enter button clicked function:
def buttonClicked(self):
msg = QMessageBox()
msg.setText("This is a message box")
But it doesn't work at all. How should I spent my problem?
Try it:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(800, 600)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(320, 330, 251, 51))
self.pushButton.setObjectName("PushButton")
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 21))
self.menubar.setObjectName("menubar")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.pushButton.setText(_translate("MainWindow", "PushButton"))
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self):
super().__init__()
self.setupUi(self)
self.pushButton.clicked.connect(self.buttonClicked) # +++
def buttonClicked(self):
msg = QtWidgets.QMessageBox.information(
self,
'Information',
'This is a message box')
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())
You have done well to create the QMessageBox but not shown them, so a possible solution is to use the exec_() method:
def buttonClicked(self):
msg = QMessageBox()
msg.setText("This is a message box")
msg.exec_()

So am testing a bit with MDI area, the problem is that when I try to Open a Subwindow inside the MDI this happens.
Any way to make the Little Subwindow bigger enough to be readble?
Am doing Everything inside an only test file.

You have to resize the QMdiSubWindow:
def Open(self):
sw = self.mdiArea.addSubWindow(self.subwindow)
self.subwindow.show()
sw.resize(640, 480)

I have 3 programs here, and I have a problem in running those 3 programs because I want it to be all imported to the main file and connected to each other after clicking the buttons on each window. My problem here is that after I have reached the 2nd window, when I click the button there then it doesn't proceed to the last window but instead the window crashes. What would I change in my program so that it will not crash?

This question already has an answer here:
PyQT: how to open new window
(1 answer)
Closed 3 years ago.
I want, from my Index.py page, to open several times the page Form.py.
For the moment when i try to open Form a second time the first Form page closes.
There is my Index.py code :
from PyQt5 import QtCore, QtGui, QtWidgets
from Form import Ui_FormWindow
class Ui_MainWindow(object):
#The function to open the Form.py
def open(self):
self.window = QtWidgets.QMainWindow()
self.ui = Ui_FormWindow()
self.ui.setupUi(self.window)
self.window.show()
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(800, 600)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(230, 180, 93, 28))
self.pushButton.setObjectName("pushButton")
self.pushButton.clicked.connect(self.open)
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 26))
self.menubar.setObjectName("menubar")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.pushButton.setText(_translate("MainWindow", "PushButton"))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
And here is the page i want to open several times, Form.py :
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_FormWindow(object):
def setupUi(self, FormWindow):
FormWindow.setObjectName("FormWindow")
FormWindow.resize(800, 600)
self.centralwidget = QtWidgets.QWidget(FormWindow)
self.centralwidget.setObjectName("centralwidget")
self.lineEdit = QtWidgets.QLineEdit(self.centralwidget)
self.lineEdit.setGeometry(QtCore.QRect(250, 190, 113, 22))
self.lineEdit.setObjectName("lineEdit")
FormWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(FormWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 26))
self.menubar.setObjectName("menubar")
FormWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(FormWindow)
self.statusbar.setObjectName("statusbar")
FormWindow.setStatusBar(self.statusbar)
self.retranslateUi(FormWindow)
QtCore.QMetaObject.connectSlotsByName(FormWindow)
def retranslateUi(self, FormWindow):
_translate = QtCore.QCoreApplication.translate
FormWindow.setWindowTitle(_translate("FormWindow", "FormWindow"))
self.lineEdit.setText(_translate("FormWindow", "Page to open"))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
FormWindow = QtWidgets.QMainWindow()
ui = Ui_FormWindow()
ui.setupUi(FormWindow)
FormWindow.show()
sys.exit(app.exec_())
I checked this answer but i don't understand how to make it work in my code.
I also edited my question in order to be a minimal reproducible example but my english is not perfect and i fear to not understand perfectly what i read on the mre tutotial so sorry
I haven't done QT stuff in a while but could it be the fact that you're instancing QtWidgets.QMainWindow again? That'd be my first guess.
