In this article we will see how we can adjust the combo box according to the size of item which has maximum size among the item list. By default we use setGeometry method and setSize method to adjust the size but it will not automatically adjust the size according to the item size. In order to adjust the size according to the maximum length item size we use adjustSize method
Syntax : combo_box.adjustSize() Argument : It takes no argument Return : None
Below is the implementation –
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 a combo box widget self.combo_box = QComboBox(self) # setting geometry of combo box self.combo_box.setGeometry(200, 150, 200, 50) # geek list geek_list = ["Sayian", "Super Saiyan", "Super Sayian 2", "Super Sayian Blue"] # making it editable self.combo_box.setEditable(True) # adding list of items to combo box self.combo_box.addItems(geek_list) # adjusting the size according to the maximum sized element self.combo_box.adjustSize()# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
