Return the layer most recently selected by the user.

This is the layer that any non-tool-driven commands should operate on, in the case where this view is the "current" one.

If the user has selected the view itself more recently than any of the layers on it, this function will return 0, and any non-tool-driven layer commands should be deactivated while this view is current. It will also return 0 if there are no layers in the view.

Note that, unlike getInteractionLayer(), this could return an invisible (dormant) layer.

virtual Layer* View::getTopLayer ( ) [inline, virtual, inherited]

Return the "top" layer in the view, whether visible or dormant.

This is the same as getLayer(getLayerCount()-1) if there is at least one layer, and 0 otherwise.

For most purposes involving interaction or commands, you probably want either getInteractionLayer() or getSelectedLayer() instead.
