PyQt5 – 为组合框设置工具提示
在这篇文章中,我们将看到如何为组合框设置工具提示。工具提示基本上是当鼠标悬停在组合框部件上时出现的提示,为了给组合框设置工具提示,我们使用setToolTip方法。
注意: 工具提示只在鼠标悬停在组合框上时可见,而不是在下拉视图中。
语法: combo_box.setToolTip(tip)
参数: 它使用字符串作为参数
返回 :无
以下是实现方法
# 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 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)
# tool tip
tip = "Sayian Tip"
# setting tool tip to the combo box
self.combo_box.setToolTip(tip)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
