_StreamMarkerSetTextColor

[jporkkahtc]

Despite its name this function sets the background to the specified color, not the text.
OK, but it appears to always set the text color to black.


Is there a way to set text color to something else?

I didn't have a problem:

   int ColorIndex=_AllocColor(0xff00,0xff);
   int type=_MarkerTypeAlloc();
   StreamMarkerIndex=_StreamMarkerAdd(0,_nrseek(),2,false,0,type,"message");
   _StreamMarkerSetTextColor(StreamMarkerIndex,ColorIndex);


I noticed that not all _AllocColor() flags are documented (F_INHERIT_COLOR_AND_STYLE,F_INHERIT_FG_COLOR, AND F_INHERIT_BG_COLOR) but from your post issue, these flags are probably not what you want.

HM... so I did make a mistake, but there is still a problem.

Given this SlickC code:
_command void colorize() name_info(',')
{
    "String"

    int ColorIndex=_AllocColor(0xff00,0xff, F_INHERIT_FG_COLOR);
    int type=_MarkerTypeAlloc();
    StreamMarkerIndex=_StreamMarkerAdd(0,_nrseek(),2,false,0,type,"message");
    _StreamMarkerSetTextColor(StreamMarkerIndex,ColorIndex);
}

When you highlight a string or a keyword, the background is red and the text turns green.
When you highlight the function name, then the text stays black as expected.

When you use inherit, you can't know for sure what will happen. All I can say is you might like what it does or you might not. It's a complicated color contrast algorithm. If there isn't enough contrast, it won't inherit the color because it would look really bad.

Interesting about contrast ... What algorithm is used?
(Request: Expose the color contrast function to script)
I used one I found on Wikipedia ... so when highlighting text it will try to pick colors that will be readable.
(That's why I was writing sqrt and cubert functions --- oddly missing from Slick math support).

Is there a way for a script to get notified when the slick colors are changed?
(A call_list macro?)
