PyQt5 – 为不可编辑组合框的行编辑部分设置不同的边框颜色
在这篇文章中,我们将看到如何为不可编辑的组合框的行编辑部分设置不同的边框颜色,行编辑是组合框中显示所选项目的部分,它在本质上是可编辑的。为了设置和访问行编辑对象,我们分别使用setLineEdit和lineEdit方法。
为了做到这一点,我们必须做以下工作。
1.创建一个组合框
2.在组合框中添加项目
3.创建一个QLineEdit对象
4.为QLineEdit对象设置不同颜色的边框
5.使行编辑对象不可编辑(只读)
6.在组合框中添加QLineEdit对象
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 check-able combo box object
self.combo_box = QComboBox(self)
# setting geometry of combo box
self.combo_box.setGeometry(200, 150, 150, 80)
# geek list
geek_list = ["Sayian", "Super Sayian", "Super Sayian 2", "Super Sayian B"]
# adding list of items to combo box
self.combo_box.addItems(geek_list)
# creating line edit object
line_edit = QLineEdit()
# setting border to the line edit part
# set different border color
line_edit.setStyleSheet("QLineEdit"
"{"
"border : 5px solid ;"
"border-color : red green blue yellow"
"}")
# making line edit object read only
line_edit.setReadOnly(True)
# adding line edit object to the combo box
self.combo_box.setLineEdit(line_edit)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
