[C++知识库]PyQt窗口阴影

PyQt窗口阴影

两种方式

• 贴图片
• 代码画

贴图

这个写的挺好
PyQt制造窗口阴影，想说爱你不容易

代码画

话不多说, 直接贴代码

from PyQt5.QtGui import QFont, QPainterPath, QPainter, QColor, QBrush, QPen

# 注意不要将窗口背景设置透明
# self.setAttribute(Qt.WA_TranslucentBackground, True)

class MyWindow(object):
	def __init__(self):
		pass
		
	def paintEvent(self, event):
	    m = 5
	    path = QPainterPath()
	    path.setFillRule(Qt.WindingFill)
	    path.addRect(m, m, self.width() - m * 2, self.height() - m * 2)
	    painter = QPainter(self)
	    painter.fillPath(path, QBrush(Qt.white))
	    color = QColor(111, 111, 111, 30)
	    for i in range(m):
	        path = QPainterPath()
	        path.setFillRule(Qt.WindingFill)
	        path.addRoundedRect(m - i, m - i, self.width() - (m - i) * 2, self.height() - (m - i) * 2, 1, 1)
	        Alpha_value = int(67 - math.sqrt(i) * 30)
	        color.setAlpha(Alpha_value)
	        painter.setPen(QPen(color, 1, Qt.SolidLine))
	        painter.drawRoundedRect(QRect(m - i, m - i, self.width() - (m - i) * 2, self.height() - (m - i) * 2), 0, 0)
