In this article we will see how we can get color effect object of the label by default there is no color effect to the label although we can create color effect then add it to the label with the help of setGraphicsEffect
method.
In order to do this we have to do the following –
1. Create a label
2. Set geometry to the label
3. Create a QGraphicsColorizeEffect object
4. Add this object to the label with the help of setGraphicsEffect method
5. Get the opacity object with the help of graphicsEffect method
Note : This object have same properties of the original object
Syntax :
# creating a color effect color_effect = QGraphicsColorizeEffect() # adding color effect to the label label.setGraphicsEffect(color_effect) # getting the color object object = label.graphicsEffect()
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
class Window(QMainWindow):
def __init__( self ):
super ().__init__()
# setting title
self .setWindowTitle( "Python " )
# setting geometry
self .setGeometry( 100 , 100 , 600 , 400 )
# calling method
self .UiComponents()
# showing all the widgets
self .show()
# method for widgets
def UiComponents( self ):
# creating label
label = QLabel( "Label" , self )
# setting geometry to the label
label.setGeometry( 200 , 100 , 150 , 60 )
# setting alignment to the label
label.setAlignment(Qt.AlignCenter)
# setting font
label.setFont(QFont( 'Arial' , 15 ))
# setting style sheet of the label
label.setStyleSheet( "QLabel"
"{"
"border : 2px solid green;"
"background : lightgreen;"
"}" )
# creating a color effect
self .color_effect = QGraphicsColorizeEffect()
# adding color effect to the label
label.setGraphicsEffect( self .color_effect)
# result label
result = QLabel( self )
# setting geometry of the result label
result.setGeometry( 200 , 200 , 300 , 30 )
# getting the color object
object = label.graphicsEffect()
# setting text to the result label
result.setText( str ( object ))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
