PyQt5 标签 - 访问阴影颜色
在本文中,我们将看到如何访问标签的阴影颜色,当我们为标签创建阴影时,默认情况下它是黑色的,尽管我们可以借助setColor
方法来设置它的颜色。
In order to access the shadow color of label with the help of color
method
Syntax : shadow.color()
Here shadow is the QGraphicsDropShadowEffect object
Argument : It takes no argument
Return : It returns QColor object
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 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)
# creating label to show the color
result = QLabel(self)
# setting geometry
result.setGeometry(100, 200, 350, 30)
# getting shadow color
shadow_color = shadow.color()
# showing text through label
result.setText("Shadow color : " + str(shadow_color))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
