PyQt5 - 进度条的彩色边框
在本文中,我们将了解如何为进度条的条创建多色边框。 Bar 是进度条的一部分,表示完整性。
下面是进度条边框与进度条多色条的表示。
为此,我们更改了 CSS 样式表中进度条的每个边框的颜色,下面是边框样式表的代码。
QProgressBar
{
border : 1px solid black;
}
QProgressBar::chunk
{
border :3px solid ;
border-top-color : red;
border-left-color :pink;
border-right-color :green;
border-bottom-color : blue;
}
下面是实现。

class Window(QMainWindow):
def __init__(self):
super().__init__()
# setting title
self.setWindowTitle("Python ")
# setting background color to window
# self.setStyleSheet("background-color : yellow")
# setting geometry
self.setGeometry(100, 100, 600, 400)
# calling method

# showing all the widgets
self.show()
# method for widgets
def UiComponents(self):
# creating progress bar
bar = QProgressBar(self)
# setting geometry to progress bar
bar.setGeometry(200, 100, 200, 30)
# setting the value
value = 70
bar.setValue(value)
# setting alignment to center
bar.setAlignment(Qt.AlignCenter)
# setting border to progress bar
# and setting multi colored border to the bar and color
bar.setStyleSheet("QProgressBar "
"{"
"border : 1px solid black;"
"}"
"QProgressBar::chunk"
"{"
"background-color : yellow;"
"border :3px solid;"
"border-top-color : red;"
"border-left-color :pink;"
"border-right-color :green;"
"border-bottom-color : blue;"
"}"
)
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
