Function Documentation

IUP_SDK_API void iupdrvFontGetCharSize	(	Ihandle *	ih,
		int *	charwidth,
		int *	charheight
	)

Retrieve the character size for the selected font. Should be used only to calculate the SIZE attribute.

IUP_SDK_API int iupdrvFontGetStringWidth	(	Ihandle *	ih,
		const char *	str
	)

Retrieve the string width for the selected font.

IUP_SDK_API void iupdrvFontGetMultiLineStringSize	(	Ihandle *	ih,
		const char *	str,
		int *	w,
		int *	h
	)

Retrieve the multi-lined string size for the selected font.
Width is the maximum line width.
Height is charheight*number_of_lines (this will avoid line size variations).

IUP_SDK_API void iupdrvFontGetTextSize	(	const char *	font,
		const char *	str,
		int	len,
		int *	w,
		int *	h
	)

Same as iupdrvFontGetMultiLineStringSize but not associated with a control. Used in IupDraw.

IUP_SDK_API void iupdrvFontGetFontDim	(	const char *	font,
		int *	max_width,
		int *	line_height,
		int *	ascent,
		int *	descent
	)

Returns information about the font.

IUP_SDK_API char* iupdrvGetSystemFont

(

void

)

Returns the System default font.

IUP_SDK_API int iupdrvSetFontAttrib	(	Ihandle *	ih,
		const char *	value
	)

FONT attribute set function.

IUP_SDK_API char* iupGetFontValue

(

Ihandle *

ih

)

Compensates IupMatrix limitation in Get FONT.

IUP_SDK_API int iupGetFontInfo	(	const char *	font,
		char *	typeface,
		int *	size,
		int *	is_bold,
		int *	is_italic,
		int *	is_underline,
		int *	is_strikeout
	)

Parse the font format description. Returns a non zero value if successful.

IUP_SDK_API int iupFontParsePango	(	const char *	value,
		char *	typeface,
		int *	size,
		int *	bold,
		int *	italic,
		int *	underline,
		int *	strikeout
	)

Parse the Pango font format description. Returns a non zero value if successful.

IUP_SDK_API int iupFontParseWin	(	const char *	value,
		char *	typeface,
		int *	size,
		int *	bold,
		int *	italic,
		int *	underline,
		int *	strikeout
	)

Parse the old IUP Windows font format description. Returns a non zero value if successful.

IUP_SDK_API int iupFontParseX	(	const char *	value,
		char *	typeface,
		int *	size,
		int *	bold,
		int *	italic,
		int *	underline,
		int *	strikeout
	)

Parse the X-Windows font format description. Returns a non zero value if successful.
