PyQt5标签 – 设置阴影的垂直偏移量
在这篇文章中,我们将看到如何设置标签阴影的垂直偏移量,偏移量基本上是标签的阴影和标签之间的距离,默认偏移量为8,尽管我们可以随时改变它。
为了达到这个目的,我们使用setYOffset方法
语法: shadow.setYOffset(n)
这里shadow是QGraphicsDropShadowEffect对象。
参数: 它接受浮动值作为参数。
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 Yoffset
shadow.setYOffset(100.5)
# 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())
