PyQt5 – 进度条的isTextVisible()方法
当我们创建一个进度条时,默认百分比是可见的。尽管我们可以通过setTextVisible方法来改变文本的可见状态。 isTextVisible方法用于检查进度条中文本的可见状态。
语法: bar.isTextVisible()
参数: 它不需要参数。
返回: 它返回bool,如果文本是可见的,则为真,如果文本是不可见的,则为假。
下面是它的实现。
# importing libraries

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 text visibility to false
bar.setTextVisible(False)
# getting the visibility status
visible = bar.isTextVisible()
# creating label to print visibility status
label = QLabel("Text visibility status = " + str(visible), self)
# adjusting the size of label
label.adjustSize()
# moving the label
label.move(160, 200)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
