PyQt5 QCommandLinkButton – 为悬停状态设置边框
在本文中,我们将了解如何根据悬停状态为 QCommandLinkButton 设置边框。命令链接按钮是一种特殊类型的按钮,它具有按钮和单选按钮的特性。默认情况下,命令链接按钮没有额外的边框,尽管当它被按下时我们能够看到边框,我们也可以为其设置自定义边框。基本上有两种悬停状态,一种是悬停,即鼠标位于命令链接按钮上,第二种是反悬停状态,即光标不在命令链接按钮上。
为此,我们将为它设置样式表代码,因为我们使用setStyleSheet
方法和命令链接按钮对象,下面是样式表代码
QCommandLinkButton::hover
{
border : 4px solid green;
}
QCommandLinkButton::!hover
{
border : 2px solid red;
}
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, 500, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for components
def UiComponents(self):
# creating a command link button
cl_button = QCommandLinkButton("Press", self)
cl_button.setCheckable(True)
# setting geometry
cl_button.setGeometry(250, 100, 200, 50)
# setting style sheet
# setting border to it for hover and anti hover state
cl_button.setStyleSheet("QCommandLinkButton::hover"
"{"
"border : 4px solid green;"
"}"
"QCommandLinkButton::! hover"
"{"
"border : 2px solid red;"
"}")
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
