PyQt5 - 如何在进度条中添加边距
在本文中,我们将了解如何为进度条设置边距。为了给进度条添加边距,我们必须更改块的样式表代码,即进度条的内部部分(加载条)。
下面是样式表代码。
QProgressBar::chunk
{
background-color: pink;
margin: 5px;
}
下面是实现。
# 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 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 progress bar
bar = QProgressBar(self)
# setting geometry to progress bar
bar.setGeometry(150, 150, 200, 30)
# set value to progress bar
bar.setValue(40)
# setting alignment to center
bar.setAlignment(Qt.AlignCenter)
# setting background color and margin
bar.setStyleSheet("QProgressBar::chunk "
"{"
"background-color: pink;"
"margin: 5px;"
"}")
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
