如何确定X11加载的字体名称?
How to determine the X11 loaded font name?
如果我使用以下方式加载字体:
char *fName = (char *)"*-c-60-iso8859-1";
XFontStruct *font = XLoadQueryFont(disp, fName);
它可以是与通配符名称匹配的几种字体中的任何一种。
如何确定实际加载的全名?
[编辑] 更正了通配符名称以匹配几个:-c-
是 -m-
,没有任何匹配。 [结束]
是字体的XA_FONT
属性
#include <X11/Xlib.h>
#include <X11/Xatom.h>
#include <stdio.h>
#include <stdlib.h>
int main (int argc, char* argv[])
{
Display* d = XOpenDisplay(0);
if (!d)
{
fprintf (stderr, "Oops, can't open display\n");
exit(EXIT_FAILURE);
}
while (*++argv)
{
XFontStruct* f = XLoadQueryFont(d, *argv);
unsigned long ret;
if (f == 0)
printf ("XLoadQueryFont failed for %s!\n", *argv);
else
{
if (!XGetFontProperty(f, XA_FONT, &ret))
printf ("XGetFontProperty(%s, XA_FONT) failed!\n", *argv);
else
printf ("Full name for %s is %s\n", *argv, XGetAtomName(d, (Atom)ret));
}
}
return 0;
}
运行:
$ ./prog r14 9x15bold foo
Full name for r14 is -Misc-Fixed-Medium-R-Normal--14-130-75-75-C-70-JISX0201.1976-0
Full name for 9x15bold is -Misc-Fixed-Bold-R-Normal--15-140-75-75-C-90-ISO8859-1
XLoadQueryFont failed for foo!
