When we create a window, by default the window size is resizable although, we can use setFixedSize() method to set the fixed size of the window but if we want to set only fix length of height or width only we cant use this method. We want to set one length fixed and other be variable in order to do so we have to use setFixedWidth() method to set fix length of width and setFizedHeight() method to set fix length of height.
Syntax :
self.setFixedWidth(width) self.setFixedHeight(height)Argument : Both take integer as argument. Action performed: setFixedWidth() sets the constant width. setFixedHeight() sets the constant height.
Code for fixed width –
# 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")
width = 500
# setting the fixed width of window
self .setFixedWidth(width)
# creating a label widget
self .label_1 = QLabel("Fixed width", self )
# moving position
self .label_1.move( 0 , 0 )
# setting up the border
self .label_1.setStyleSheet("border : 3px solid black;")
# resizing label
self .label_1.resize( 120 , 80 )
# 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 ())
|
