Hi,
Thanks for your answer.
As I have to know exact width of the string, I found that solution :
For every font I use, I calculate the width of a space.
And every time I use XftTextExtents8, I test if the last character of
the string is a space or not.
If it's a space, I add the width of the space to the width of the string.
Cheers,
Lucien

Hi,
i did not see an answer so i will try:
The docu says: "XftTextExtents8 computes the pixel extents of "string" when drawn with
"font". "
IMHO:
the point here is: "pixel extents" i read "find the last pixel"
white space has no pixel so it should be ignored.
In that logic leading spaces get not ignored because they cause an offset.
You expected "string width" what is obviously not the same-

Hello,
I use XftTextExtents8 (display,font,(FcChar8
*)str,strlen(str),&glyphInfo); instruction to compute width of string str
Here are values of glyphInfo.width with following strings:
String glyphInfo.width
-------------------------------------
"e" 9
" e" (leading space) 13
"e " (trailing space) 9
"e e" 22
So it seems thattrailing spaces are not taken into account to compute
string width.
is it a bug ?
