I see.
Same also applies to any onscreen display of scrolling status etc.,
except that it doesn't have the same insertion-point requirement.
Still possible (at least I think)
Highlighter stores something called a range for each line (line as in
textbuffer lines, so scrolling of display does not matter)
They are automatically adjusted if lines are added/inserted/removed
from/to the textbuffer
So you could write a HL, that stores a list of x-positions for each
line, together with the attributes. (If you edit the line itself, you
need to adjust the list)
The highlighter can then return the text, cut into "tokens" (in your
case each continuous group of chars with the same attributes), and
supply the attributes for each token.
By default the "Range" is not freed, when the line is dropped (e.g. if
it is an enum or set, then just the memory is dropped).
But the highlighter allows to override that code, so it can be added.
Depends how interested you are.
I can assist, and help put together the framework, but you'll have to
implement the rest.
It sounds like a lot of work, shoehorning something which isn't really
its forte into Synedit.
Before anything more, I'll drop a note to Cmdline's author (if he's not
in here already) and see if he's got any suggestions.
Otherwise, can anybody say whether are there any stringgrid derivatives
etc. that will do this?
