PyQt5 - 设置组合框的帮助文本
在本文中,我们将看到我们如何将帮助文本设置到组合框,帮助文本主要用于告诉程序员参考链接等紧急信息,程序员将帮助文本设置到组合框,以便当其他程序员遇到困难时在理解组合框时,他/她可以从帮助文本中获得帮助。
为了将帮助文本设置到组合框,我们使用setWhatsThis
方法。
Syntax : combo_box.setWhatsThis(help)
Argument : It takes string as argument
Return : None
下面是实现
# importing libraries

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 a combo box widget
self.combo_box = QComboBox(self)
# setting geometry of combo box
self.combo_box.setGeometry(200, 150, 150, 30)
# geek list
geek_list = ["Sayian", "Super Sayian"]
# making it editable
self.combo_box.setEditable(True)
# adding list of items to combo box
self.combo_box.addItems(geek_list)
# help text
help = "Sayian Help text"
# setting help text to the combo box
self.combo_box.setWhatsThis(help)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
