Class: QgsMapTip

class qgis.gui.QgsMapTip

Bases: PyQt5.QtWidgets.QWidget

Default constructor

A maptip is a class to display a tip on a map canvas when a mouse is hovered over a feature.

Since QGIS 2.16 a maptip can show full html. QgsMapTip is a QgsWebView, so you can load full HTML/JS/CSS in it.

The code found in the map tips tab is inserted in a inline-block div so the frame can be resized based on the content size.

If no element in the html has a width attribute, the frame will squeeze down to the widest word. To avoid this you can wrap your HTML in a div style=”width:300px” or similar.

JS can be included using the script tag as usual, while CSS files must be linked using link rel=”stylesheet” href=”URL.css” the html specs discourages link rel=”stylesheet” in the body, but all browsers allow it. see https://jakearchibald.com/2016/link-in-body
