import sys
from PyQt5.QtWidgets import (QApplication, QWidget, 
    QToolTip, QPushButton)
from PyQt5.QtGui import QFont

class Example(QWidget):

  def __init__(self):
    super().__init__()

    self.initUI()

  def initUI(self):

    QToolTip.setFont(QFont('楷体', 14))

    self.setToolTip(&#39;这是一个 <b>QWidget</b> 控件&#39;)

    btn = QPushButton(&#39;按钮&#39;, self)
    btn.setToolTip(&#39;这是一个 <b>QPushButton</b> 控件&#39;)
    btn.resize(btn.sizeHint())
    btn.move(50, 50)

    self.setGeometry(300, 300, 300, 220)
    self.setWindowTitle(&#39;工具提示&#39;)    
    self.show()

if __name__ == &#39;__main__&#39;:

  app = QApplication(sys.argv)
  ex = Example()
  sys.exit(app.exec_())

In this example, we display tooltips for two PyQt5 controls.

 QToolTip.setFont(QFont('楷体', 14))

This static method sets the font used for tool tips, we use 10px size with italic font

self.setToolTip('This is AQWidget control')

Create a tool tip for this window control. We use the setTooltip() method. We can use rich text format for the displayed text.

btn = QPushButton('按钮', self)
btn.setToolTip(&#39;这是一个 <b>QPushButton</b> 控件&#39;)

We create a button control and set the tooltip of the control.

 btn.resize(btn.sizeHint())
 btn.move(50, 50)

Set the size and position of the button control in the form. The sizeHint() method gives the button a recommended size.
