PyQt5标签 – 为阴影设置颜色
在这篇文章中,我们将看到如何为标签设置阴影的颜色,当我们为标签创建阴影时,它默认为黑色,尽管我们可以为它设置颜色。
为了给标签的阴影设置颜色,可以使用setColor方法。
语法: shadow.setColor(color_object)
这里shadow是QGraphicsDropShadowEffect对象。
参数: 它以颜色对象为参数,例如Qt.green。
返回: 无
下面是实现方法
# 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 background color of window
# self.setStyleSheet("background-color : black;")
# 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 label
label = QLabel("Label", self)
# setting alignment
label.setAlignment(Qt.AlignCenter)
# setting geometry to the label
label.setGeometry(200, 100, 150, 60)
# setting border
label.setStyleSheet("border : 8px solid black")
# creating a QGraphicsDropShadowEffect object
shadow = QGraphicsDropShadowEffect()
# setting blur radius
shadow.setBlurRadius(20)
# setting border color
shadow.setColor(Qt.green)
# adding shadow to the label
label.setGraphicsEffect(shadow)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
