PyQt5 – 如何根据项目的大小来调整组合框的大小
在这篇文章中,我们将看到如何根据项目列表中具有最大尺寸的项目的大小来调整组合框。默认情况下,我们使用setGeometry方法和setSize方法来调整大小,但它不会根据项目的大小来自动调整大小。为了根据最大长度的项目尺寸来调整尺寸,我们使用调整尺寸方法
语法: combo_box.adjustsize()
参数: 不需要参数
返回: 无
以下是实现方法
# 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 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 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
