difficulty in print("ok") whenever I click anywhere in the APP GUI

I used QT Designer to design a GUI, I then imported the .ui file into my python code via : 

ui_file = QFile(ui_file)
        ui_file.open(QFile.ReadOnly)
        loader = QUiLoader()
        self.window = loader.load(ui_file)
        ui_file.close()

and everything works fine, the GUI does appear and is functional when I run the python code However I am facing difficulties in achieving the functionality: "I want to print("ok") whenever I click on any point on the GUI". here is my code:

import sys
from PySide2.QtUiTools import QUiLoader
from PySide2.QtWidgets import QApplication, QComboBox, QCheckBox, QLabel, QPushButton, QFrame, QAction, QDesktopWidget, QTabWidget, QMainWindow, QWidget
from PySide2.QtCore import QFile, QObject,Qt, QPoint
from PySide2 import QtCore, QtGui

class MyApp(QObject):
    def __init__(self, ui_file, parent=None):
        super(MyApp, self).__init__(parent)
        ui_file = QFile(ui_file)
        ui_file.open(QFile.ReadOnly)
        loader = QUiLoader()
        self.window = loader.load(ui_file)
        ui_file.close()
        self.window.setWindowFlags(QtCore.Qt.FramelessWindowHint)
        self.window.show()

    def mousePressEvent(self, event):    
        print("ok")

if __name__ == '__main__':
    app = QApplication(sys.argv)
    form = MyApp('GUI.ui')
    sys.exit(app.exec_())

here is the UI file: PS. make a new GUI.ui file and edit it with notepad and add the following code and you will have my GUI.ui file:

Solution

  • MyApp not a widget so the mousePressEvent does not exist, and less is the window. So in these cases you should use an event filter:

    import sys
from PySide2 import QtCore, QtWidgets, QtUiTools

class MyApp(QtCore.QObject):
    def __init__(self, ui_file, parent=None):
        super(MyApp, self).__init__(parent)
        ui_file = QtCore.QFile(ui_file)
        if ui_file.open(QtCore.QFile.ReadOnly):
            loader = QtUiTools.QUiLoader()
            self.window = loader.load(ui_file)
            self.window.installEventFilter(self)
            self.window.setWindowFlags(QtCore.Qt.FramelessWindowHint)
            self.window.show()

    def eventFilter(self, obj, event):
        if obj is self.window:
            if event.type() == QtCore.QEvent.MouseButtonPress:
                print("ok")
        return super(MyApp, self).eventFilter(obj, event)

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    form = MyApp('GUI.ui')
    sys.exit(app.exec_())
