GeometryType
The geometry types are used to group Qgis::WkbType in a coarse way.
Definition qgis.h:255
Map canvas is a class for displaying all GIS data types on a canvas.
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.
virtual void syncToLayer(QgsMapLayer *layer)
Reset to original (vector layer) values.
Base class for all map layer types.
Definition qgsmaplayer.h:75
A bar for displaying non-blocking messages to the user.
Symbol selector widget that can be used to select and build a symbol.
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.
