I am trying to use the various Pf* functions to get information about the
font a widget has set, like a label or text box. I have come across the
following…
If I use…
PtGetResource( ABW_txtNewLine, Pt_ARG_TEXT_FONT, &FontString, 0);
PfQueryFontInfo( FontString, &info);
The info stucture (FontQueryInfo) has a 0 for size, no matter what the size
is set to. For example if I set the font in the widget to 10 point, bold,
(in builder), then query it everything seems set correctly but the size.
The next thing I tried was to use the
FontIDStruct = PfDecomposeStemToID( info.font );
Trying to use FontIDStruct->ulSize, for example, results in a compile error
about an undefined type “__TS_FONT_ID” and a complaint about a forward
declaration of same. Examining the 6.1 and 6.2 include files (Pf.h) I see
that there is a bit of a difference…
IN 6.1 you have defined…
typedef struct _TS_FONT_ID
{ uint32_t ulFlags;
uint32_t ulSize;
uint32_t ulSpare[8];
uchar_t * pucStem;
uchar_t * pucDescription;
uchar_t * pucSpare[2];
} FontID;
Whereas in 6.2…
typedef struct _TS_FONT_ID FontID;
I realize that if I parse out the font name string from the Pt_ARG_TEXT_FONT
resources I can get most of the information, but I figured that if the API
could do it, why waste the effort.
I am using 6.2SE.
Thanks

Yes, this indicates that it is a scalable font.

The structure was never documented for this reason.
You can use routine PfFontSize() to retrieve the point size,
which is available in 6.1 and 6.2 versions.
