Added Layer enum that groups
SC_LAYER_BASE
,SC_LAYER_UNDER_TEXT
andSC_LAYER_OVER_TEXT
. Added propertiesSelectionLayer
andCaretLineLayer
in Scintilla control to set the layer of the text selection and the layer of the currently highlighted line whenCaretLineVisible
is set.Note: one thing that I couldn't get around is the default value of
CaretLineLayer
property. While for a newly created control it reportsBase
or0
, the behavior is as ifOverText
(or2
) is selected. This might create confusion but I'm not sure if there is anything to be done as, if there is a bug, that seems to be in the native control side. Perhaps addingCaretLineLayer = Layer.Base
in the constructor might be enough?Fixes #24
