In this article we will see how we can drag and drop the calendar in the main window. In order to drag the calendar user has to click on the title bar of the calendar and move the cursor to move the calendar and in order to drop just release the cursor.
Implementation steps :
1. Create a Calendar class that inherits the QCalendarWidget
2. Inside the Calendar class override the mouse press and release event inside the events update the move flag
3. Create a main window class
4. Create a Calendar object
5. Set main window mouse tracking enabled
6. Override the mouse move event
7. Inside the mouse move event get the x, y co-ordinates and change the position of calendar according to it
Below is the implementation
# 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)
# overriding the mouse press event
def mousePressEvent( self , QMouseEvent):
# making flag true
window.move_calendar = True
# overriding the mouse release event
def mouseReleaseEvent( self , event):
# making flag false
window.move_calendar = False
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()
# creating amove flag
self .move_calendar = False
# method for components
def UiComponents( self ):
# creating a QCalendarWidget object
# as Calendar class inherits QCalendarWidget
self .calendar = Calendar( self )
# enabling mouse tracking
self .calendar.setMouseTracking( True )
self .setMouseTracking( True )
# setting geometry to the calendar
self .calendar.setGeometry( 50 , 10 , 250 , 250 )
# setting cursor
self .calendar.setCursor(Qt.PointingHandCursor)
# overriding the mouse move event
def mouseMoveEvent( self , event):
# getting x, y co-ordinates
x = event.x()
y = event.y()
# checking the flag
if self .move_calendar:
# moving the calendar
self .calendar.move(x, y)
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
