PyQt5 – 如何使可编辑的组合框的文本居中对齐
在这篇文章中,我们将看到如何将组合框的文本居中对齐。默认情况下,组合框的文本是左对齐的,而且组合框本身没有任何对齐方法。
为了 使文本居中对齐,我们必须做以下工作–
1.创建一个组合框
2.使组合框可编辑(可选)
3.从组合框中制作行编辑对象
4.对准行编辑的中心
语法: 用于创建行编辑并设置其对齐方式
# getting the line edit of combo box
line_edit = self.combo_box.lineEdit()
# setting line edit alignment to the center
line_edit.setAlignment(Qt.AlignCenter)
以下是执行情况
# 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, 150, 30)
# geek list
geek_list = ["Sayian", "Super Saiyan", "Super Sayian 2", "Super Sayian B"]
# making it editable
self.combo_box.setEditable(True)
# adding list of items to combo box
self.combo_box.addItems(geek_list)
# getting the line edit of combo box
line_edit = self.combo_box.lineEdit()
# setting line edit alignment to the center
line_edit.setAlignment(Qt.AlignCenter)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
