PyQt5 – 如何为进度条设置文本
在这篇文章中,我们将看到如何为进度条设置文本。当我们创建一个进度条时,只有进度百分比文本是可见的,但我们也可以在上面设置一些文本。下面是普通进度条和带文本的进度条的对比。
为了做到这一点,我们将使用 setFormat 方法,虽然它是用来设置格式的,即百分比指标,但如果我们把普通文本传给它,它将在进度条中显示。
# 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(200, 150, 200, 30)
# set value to progress bar
bar.setValue(70)
# setting text
bar.setFormat('This is progress bar')
# setting alignment to centre
bar.setAlignment(Qt.AlignCenter)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
