PyQt 圆形闪屏角

Question

我有一个 PyQt5 启动画面。我想要做的是绕过闪屏本身的角落。但是，当我尝试splash.setStyleSheet(u"border: 1px solid black; border-radius: 10px;") 时，它会为初始屏幕内部的小部件添加圆形边框，而不是初始屏幕本身。我怎么能拐弯抹角。

这是我的启动画面的代码：

splash_pix = QtGui.QPixmap('con.png')

splash = QtWidgets.QSplashScreen(splash_pix, Qt.WindowStaysOnTopHint | Qt.FramelessWindowHint | Qt.WindowStaysOnTopHint)
splash.resize(700, 700)
splash.setStyleSheet(u"background-color: rgb(71, 71, 71); border: 1px solid black; border-radius: 10px;")
qtRectangle = splash.frameGeometry()
centerPoint = QtWidgets.QDesktopWidget().availableGeometry().center()
qtRectangle.moveCenter(centerPoint)
splash.move(qtRectangle.topLeft())
# adding progress bar
progressBar = QtWidgets.QProgressBar(splash)
progressBar.setGeometry(QtCore.QRect(0, 390, 571, 23))
progressBar.setStyleSheet(u"QProgressBar{\n"
"\n"
"background-color: rgb(98, 114, 164);\n"
"color: rgb(200, 200, 200);\n"
"border-style: none;\n"
"border-radius: 10px;\n"
"text-align: center;\n"
"}\n"
"\n"
"QProgressBar::chunk{\n"
"\n"
"   border-radius: 10px;\n"
"   background-color: qlineargradient(spread:pad, x1:0, y1:0, x2:0.943182, y2:0, stop:0 rgba(254, 121, 199, 255), stop:1 rgba(170, 85, 255, 255));\n"
"}")


lodingLbl = QtWidgets.QLabel(splash)

loding_font = QFont()
loding_font.setPointSize(14)
loding_font.setFamily(u"Franklin Gothic Medium")

lodingLbl.setFont(loding_font)
lodingLbl.setStyleSheet("color : rgb(200, 200, 200)")

lodingLbl.setText("STARTING PROGRAM")

lodingLbl.setAlignment(Qt.AlignCenter)


splashLoadingLayout = QtWidgets.QVBoxLayout()
splashLoadingLayout.addStretch()
splashLoadingLayout.addWidget(lodingLbl)
splashLoadingLayout.addWidget(progressBar)
splashLoadingLayout.addStretch()
splashLoadingLayout.setAlignment(Qt.AlignVCenter)

progressBar.setTextVisible(False)

splash.setLayout(splashLoadingLayout)

splash.setMask(splash_pix.mask())

splash.show()

好的，我想通了。如果启动画面只围绕小部件的角落，那么我所要做的就是创建一个主 Qwidget 并将启动画面设置为那个。然后，我可以使用splash.setAttribute(Qt.WA_TranslucentBackground) 将背景设置为透明。

所以，我编辑的只是：

splashLoadingLayout = QtWidgets.QVBoxLayout()
splashLoadingLayout.addStretch()
splashLoadingLayout.addWidget(lodingLbl)
splashLoadingLayout.addWidget(progressBar)
splashLoadingLayout.addStretch()
splashLoadingLayout.setAlignment(Qt.AlignVCenter)

progressBar.setTextVisible(False)

newWid = QtWidgets.QWidget()

newWid.setLayout(splashLoadingLayout)

splashPermLayout = QtWidgets.QVBoxLayout()
splashPermLayout.addWidget(newWid)

splash.setLayout(splashPermLayout)

splash.setMask(splash_pix.mask())

splash.show()

但是，标签仍然会有边框。所以，为了禁用它，我在样式表中删除了border: 1px solid black 给我：splash.setStyleSheet(u"border-radius: 33px;")。这解决了一切

我希望这对所有遇到此问题的人有所帮助！
