Map canvas is a class for displaying all GIS data types on a canvas.
Definition: qgsmapcanvas.h:90
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:73
Represents a raster layer.
Abstract base class for widgets which configure a QgsRasterRenderer.
QgsRasterRendererWidget * currentRenderWidget()
Returns the active render widget.
