PyQt5 - 将工具提示持续时间设置为状态栏
在本文中,我们将了解如何设置工具提示持续时间。我们可以使用setToolTip
方法对状态栏对象进行工具提示,但默认情况下,工具提示不会在一段时间后自动消失。我们可以通过使用状态栏对象的setToolTipDuration
方法来设置这个消失时间。
Syntax : self.statusBar().setToolTipDuration(ms)
Argument : It take integer as argument which represent milliseconds
Action performed : It set time duration to tool tip of status bar.
代码 :
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
import sys
class Window(QMainWindow):
def __init__(self):
super().__init__()
# set the title
self.setWindowTitle("Python")
# setting the geometry of window
self.setGeometry(60, 60, 600, 400)
# setting status bar message
self.statusBar().showMessage("This is status bar")
# setting border
self.statusBar().setStyleSheet("border :3px solid black;")
# setting tool tip for status bar
self.statusBar().setToolTip("Hello ! from status bar")
# setting tool tip duration
self.statusBar().setToolTipDuration(500)
# creating a label widget
self.label_1 = QLabel("status bar", self)
# moving position
self.label_1.move(100, 100)
# setting up the border
self.label_1.setStyleSheet("border :1px solid blue;")
# resizing label
self.label_1.adjustSize()
# show all the widgets
self.show()
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
此工具提示将在 500 毫秒后消失,即 5 秒
