class KisGroupLayer
 

Detailed Description

Abstract class that represents the concept of a Layer in Chalk.

This is not related to the paint devices: this is merely an abstraction of how layers can be stacked and rendered differently. Regarding the previous-, first-, next- and lastChild() calls, first means that it the layer is at the top of the group in the layerlist, using next will iterate to the bottom to last, whereas previous will go up to first again.
