NAME
XmFontListGetNextFont -- A font list function that allows applications to access the fonts and character sets in a font list
SYNOPSIS
#include <Xm/Xm.h>
Boolean XmFontListGetNextFont(
XmFontContext context,
XmStringCharSet *charset,
XFontStruct **font);
DESCRIPTION
XmFontListGetNextFont accesses the character set and font for the next entry of the font list. The application first uses the XmFontLis-
tInitFontContext routine to create a font list context. The application then calls XmFontListGetNextFont repeatedly with the same context.
Each succeeding call accesses the next element of the font list. When finished, the application calls XmFontListFreeFontContext to free the
allocated font list context.
This routine allocates memory for the character set string that must be freed by the application. The function allocates memory for
charset. The application is responsible for managing the allocated memory. The application can recover the allocated memory by calling
XtFree.
This function is obsolete and exists for compatibility with previous releases. It is replaced by XmFontListNextEntry. If XmFontListGet-
NextFont is passed a context that contains a font set entry, it will return the first font of the font set. The next call to the function
will move to the next entry in the font list.
context Specifies the font list context
charset Specifies a pointer to a character set string; the routine returns the character set for the current font list element
font Specifies a pointer to a pointer to a font structure; the routine returns the font for the current font list element
RETURN
Returns True if the returned values are valid; otherwise, returns False.

NAME
XmFontListNextEntry -- A font list function that returns the next entry in a font list
SYNOPSIS
#include <Xm/Xm.h>
XmFontListEntry XmFontListNextEntry(
XmFontContext context);
DESCRIPTION
XmFontListNextEntry returns the next entry in the font list. The application uses the XmFontListInitFontContext routine to create a font
list context. The first call to XmFontListNextEntry sets the context to the first entry in the font list. The application then calls
XmFontListNextEntry repeatedly with the same context. Each succeeding call accesses the next entry of the font list. When finished, the
application calls XmFontListFreeFontContext to free the allocated font list context.
context Specifies the font list context
RETURN
Returns NULL if the context does not refer to a valid entry or if it is at the end of the font list; otherwise, it returns a font list
entry. If the function does return a font list entry, the font list entry is not a copy. Therefore, the application should not free the
returned font list entry.

We use the debian 4.0 Linux with the wine 1.0. When we run our application on this platform, there is a problem:
The Barcode can't be displayed correctly, but occurs some Garbled. The font we use is “Carolinabar-B39-25F2”. But when we install the wine-0.9.25 instead of wine-1.0, the barcode can... (1 Reply)

Hello,
I am interested in writing a context driven NGram analysis i.e. detecting the frequency of utterance of a given character based on its immediate context i.e. the character which can preced and follow the given entity. In the case of Intial and Final the context would be immediate character... (4 Replies)
