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

 QToolTip.setFont(QFont(&#39;楷体&#39;, 14))

Copy after login

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

Copy after login

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

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

Copy after login

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