Wow, that was a long time ago! IIRC, you use clearRect() with an appropriate
GC in textDisp.c. Look at styleOfPos() where it returns a FILL_MASK style,
which indicates that we need to blank out to the right hand margin, and how
it's used in drawString(). You can see there how the bground variable in
drawString() picks up the the right color and to use it.
Back in styleOfPos() notice the section (textDisp.c:2184):
if (lineIndex >= lineLen)
style = FILL_MASK;
else if (styleBuf != NULL) {
...
which essentially says "if we are at a line-end we will ignore SH style". To
get line-end fills colored with the SH background, remove the word "else",
and use "style |= " instead of "style = " as follows:
if (lineIndex >= lineLen)
style = FILL_MASK;
if (styleBuf != NULL) { /* ---------------- NOTE: NO ELSE */
/* pick up styleBuf's style value separately */
int styleChar = (unsigned char)BufGetCharacter(styleBuf, pos);
if (styleChar == textD->unfinishedStyle) {
/* encountered "unfinished" style, trigger parsing */
(textD->unfinishedHighlightCB)(textD, pos, textD->highlightCBArg);
styleChar = (unsigned char)BufGetCharacter(styleBuf, pos);
}
style |= styleChar; /* add styleBuf value found to style bitmap */
}
No Xlib required!
Now the question: why?
