PyQt5 QCalendarWidget – How to drag and drop it anywhere in the window using mouse
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
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) # 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 ()) |
