Though it is possible to solve the first problem, this problem may make the wrapper very com 

plex. Thus, I decided to modify the original source and leave the wrapper simple, instead of

writing a complete wrapper. However, if

XGCValues.font

is set and

XCreateGC()

is called, it

is needed to avoid

XCreateGC

to fail because of null font specification. Thus I wrote a wrapper

of

XCreateGC

.

To solve the second problem, I wrote a wrapper of

XFontSet

which has structure members of

ascent

and

descent

. Thus all wrapper functions are related to this wrapper structure.

To solve the third problem, I wrote a wrapper of

XCreateFontSet()

. This part can be used for

many X clients which are already internationalized using fontset related functions, because these

softwares have the same problem. Explanation on this problem and solution will be supplied in

other section.

13.4.3 Usage of the wrapper

Replace the following structure and functions. You can use replacement faculty of your text editor.

  XFontStruct  > QuasiXFontStruct

  XLoadQueryFont()  > QuasiXLoadQueryFont()

  XFreeFont()  > QuasiXFreeFont()

  XTextExtents()  > QuasiXTextExtents()

  XTextWidth()  > QuasiXTextWidth()

  XGetWMIconName()  > QuasiXGetWMIconName()

  XGetWMName()  > QuasiXGetWMName()

  XFetchName()  > QuasiXFetchName()

  XGetIconName()  > QuasiXGetIconName()

  XChangeGC()  > QuasiXChangeGC()

  XCreateGC()  > QuasiXCreateGC()

The following two wrapper functions need an additional parameter.

  XDrawString(Display *d, Window w, GC gc, int x, int y, const char *string, int len)  > QuasiX 

DrawString(Display *d, Window w, QuasiXFontStruct *q, GC gc, int x, int y, char *string, int

len)
