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.
Base class for all map layer types.
Definition qgsmaplayer.h:76
Master widget for configuration of labeling of a mesh layer.
void auxiliaryFieldCreated()
Emitted when an auxiliary field is created.
Represents a mesh layer supporting display of data on structured or unstructured meshes.
A bar for displaying non-blocking messages to the user.
virtual void setDockMode(bool dockMode)
Set the widget in dock mode which tells the widget to emit panel widgets and not open dialogs.
