Base class for renderer settings widgets
|
|
|
|
WORKFLOW:
|
|
- open renderer dialog with some RENDERER (never null!)
|
|
- find out which widget to use
|
|
- instantiate it and set in stacked widget
|
|
- on any change of renderer type, create some default (dummy?) version and change the stacked widget
|
|
- when clicked OK/Apply, get the renderer from active widget and clone it for the layer
