When we create a window, by default, it is resizable but with the help of setFixedSize() method we can fix the size of window. But what if we want to resize the window up-to some extent; in order to do this, we have to set the maximum size of the window. We will use setMaximumSize() method.
Syntax : self.setMaximumSize(width, height)
Argument : It takes two argument both integer i.e width and height.
Action performed : It set the maximum size of window.
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") width = 500 height = 400 # setting the maximum size self.setMaximumSize(width, height) # creating a label widget self.label_1 = QLabel("Maximum size", 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()) |
Output :
