PyQt圆形Spalsh屏幕角

Question

我有一个PyQt5启动屏幕。我想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，它会向启动屏幕内的小部件添加一个圆形边框，而不是启动屏幕本身。我怎么能拐弯呢

这是我的启动屏幕的代码：

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()

好吧，我已经弄明白了。如果启动屏幕只环绕小部件的各个角落，那么我所要做的就是创建一个主Qwidget并将启动屏幕设置为该位置。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()

然而，标签仍有边界。因此，为了禁用该功能，我删除了样式表中的border: 1px solid black，以获得：splash.setStyleSheet(u"border-radius: 33px;")。这一切都解决了

我希望这能帮助其他遇到这个问题的人
