When we create a window in PyQt5, by default, there is no special type of border to it. But we change the style, thickness as well as color of the main window by using setStyleSheet()
method.
Below is how normal border vs styled border looks like
Syntax : self.setStyleSheet(“border : 3px dashed blue;”)
Argument: It takes string as argument.
"border : size_of_border type_of_border color_of_border;"
Action performed : It sets the border style.
Code :
# importing the required libraries from PyQt5.QtCore import * from PyQt5.QtGui import * from PyQt5.QtWidgets import * import sys class Window(QMainWindow): def __init__( self ): super ().__init__() # set the title self .setWindowTitle( "Python" ) # setting geometry self .setGeometry( 100 , 100 , 600 , 400 ) # setting up the style of border self .setStyleSheet( "border : 3px dashed blue;" ) # creating a label widget self .label_1 = QLabel( "new border " , self ) # moving position self .label_1.move( 100 , 100 ) # setting up the border self .label_1.setStyleSheet( "border :3px solid black;" ) # show all the widgets self .show() # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
