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.
A bar for displaying non-blocking messages to the user.
Contains settings for how a map layer will be labeled.
Base class for any widget that can be shown as a inline panel.
virtual void setDockMode(bool dockMode)
Set the widget in dock mode which tells the widget to emit panel widgets and not open dialogs.
Contains settings which reflect the context in which a symbol (or renderer) widget is shown,...
Represents a vector layer which manages a vector based data sets.
Configuration of a single style within QgsVectorTileBasicLabeling.
Basic labeling configuration for vector tile layers.
Implements a map layer that is dedicated to rendering of vector tiles.
