PyQt5 QCalendarWidget – Setting Mouse Move Event
In this article we will see how we can implement the mouse move event for the QCalendarWidget. This event handler, for event event, can be reimplemented in a subclass to receive mouse move events for the widget. If mouse tracking is switched off, mouse move events only occur if a mouse button is pressed while the mouse is being moved. If mouse tracking is switched on, mouse move events occur even if no mouse button is pressed.
Implementation steps:
1. Create a Calendar class that inherits the QCalendarWidget
2. Create alabel to show the updates
3. Override the mouseMoveEvent and set the position to the label
4. Create a Calendar object inside the main window
5. Set various properties to the calendar
Below is the implementation
Python3
# importing libraries from PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGui from PyQt5.QtGui import * from PyQt5.QtCore import * import sys # QCalendarWidget Class class Calendar(QCalendarWidget): # constructor def __init__( self , parent = None ): super (Calendar, self ).__init__(parent) self .setMouseTracking( True ) class Window(QMainWindow): def __init__( self ): super ().__init__() # setting title self .setWindowTitle("Python ") # setting geometry self .setGeometry( 100 , 100 , 650 , 400 ) # calling method self .UiComponents() # showing all the widgets self .show() # method for components def UiComponents( self ): # creating a QCalendarWidget object # as Calendar class inherits QCalendarWidget self .calendar = Calendar( self ) # turing on the mouse tracking self .setMouseTracking( True ) # setting geometry to the calendar self .calendar.setGeometry( 50 , 10 , 250 , 250 ) # setting cursor self .calendar.setCursor(Qt.PointingHandCursor) # creating label to show the properties self .label = QLabel( self ) # setting geometry to the label self .label.setGeometry( 100 , 280 , 250 , 60 ) # making label multi line self .label.setWordWrap( True ) def mouseMoveEvent( self , event): self .label.setText( 'coords: ( % d : % d )' % (event.x(), event.y())) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
