PyQt5 - 为 ComboBox 的 lineedit 部分添加边框
在本文中,我们将看到如何为组合框的行编辑部分设置边框。行编辑部分是组合框显示所选项目的部分,它本质上是可编辑的。为了设置和访问行编辑对象,我们分别使用setLineEdit
和lineEdit
方法。下面是普通组合框与行编辑部分有边框的组合框的表示。
In order to do this, follow these steps –
1. Create a combo box
2. Add item to the combo box
3. Create a QLineEdit object
4. Set border to the QLineEdit object
5. Add QLineEdit object to the combo box
句法 :
# creating line edit object
line_edit = QLineEdit()
# setting border to the line edit
line_edit.setStyleSheet("QLineEdit"
"{"
"border : 2px solid green;"
"}")
# adding line edit object to the combo box
self.combo_box.setLineEdit(line_edit)
下面是实现
# 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 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
line_edit.setStyleSheet("QLineEdit"
"{"
"border : 2px solid green;"
"}")
# 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 :
