Map canvas is a class for displaying all GIS data types on a canvas.
Definition: qgsmapcanvas.h:86
A panel widget that can be shown in the map style dock.
virtual void apply()=0
Called when changes to the layer need to be made.
A bar for displaying non-blocking messages to the user.
Definition: qgsmessagebar.h:61
Base class for any widget that can be shown as a inline panel.
Definition of map rendering of a subset of vector tile data.
The default vector tile renderer implementation.
Implements a map layer that is dedicated to rendering of vector tiles.
GeometryType
The geometry types are used to group QgsWkbTypes::Type in a coarse way.
