SETADDITIONALSELFORE has no effect without SETSELFORE

[Paul K]

Hi Neil,

I've been working with styling additional selections and ran into an
interesting issue. It seems like SetAdditionalSelFore doesn't seem to have
any effect until a call for SetSelFore is made. Is this a feature? Also,
SetSelFore and SetSelBack set colors for all selections, which does make
sense, but it may be useful to mention this in the documentation for
SetAdditionalSel* methods. Thank you.

Paul.

There are two arguments to SetSelFore which set independent properties: useSelectionForeColour and colour. SetAdditionalSelFore only has a colour argument so is incapable of setting whether or not to use selection foreground colours.

Also, SetSelFore and SetSelBack set colors for all selections, which does make sense, but it may be useful to mention this in the documentation for SetAdditionalSel* methods.

Do you have a proposal for wording?

Maybe something like this (I copied the first sentence without changes):

Modify the appearance of additional selections so that they can be
differentiated from the main selection which has its appearance set with
SCI_SETSELALPHA <http://www.scintilla.org/ScintillaDoc.html#SCI_SETSELALPHA>
,SCI_GETSELALPHA<http://www.scintilla.org/ScintillaDoc.html#SCI_GETSELALPHA>
, SCI_SETSELFORE <http://www.scintilla.org/ScintillaDoc.html#SCI_SETSELFORE>,
and SCI_SETSELBACK<http://www.scintilla.org/ScintillaDoc.html#SCI_SETSELBACK>
. *SCI_SETADDITIONALSELFORE *and *SCI_SETADDITIONALSELBACK* calls have no
effect until SCI_SETSELFORE<http://www.scintilla.org/ScintillaDoc.html#SCI_SETSELFORE>
and SCI_SETSELBACK<http://www.scintilla.org/ScintillaDoc.html#SCI_SETSELBACK> are
called with useSelection*Colour value set to true. Subsequent calls to
SCI_SETSELFORE <http://www.scintilla.org/ScintillaDoc.html#SCI_SETSELFORE>,
and SCI_SETSELBACK<http://www.scintilla.org/ScintillaDoc.html#SCI_SETSELBACK> will
overwrite the values set by SCI_SETADDITIONALSEL* functions.

(I'm not sure if any of this applies to ALPHA calls as well).
