List all fonts matching hints. Returns an array of FXFontDesc objects.
Return an FXFont instance, initialized from a font description.
| a: | an application instance [FXApp] |
| fontDesc: | a font description [FXFontDesc] |
Return an FXFont instance initialized with the given face name, size in points (pixels), weight, slant, character set encoding, set width, and hints. The font name may be comprised of a family name and optional foundry name enclosed in square brackets, for example, "helvetica [bitstream]".
| a: | an application instance [FXApp] |
| face: | font face name [String] |
| size: | requested font size, in points [Integer] |
| weight: | requested font weight [Integer] |
| encoding: | requested font encoding [Integer] |
| setWidth: | requested font set width [Integer] |
| hints: | font construction hints for font matching algorithm [Integer] |
Construct a font with given font description of the form:
fontname [ "[" foundry "]" ] ["," size ["," weight ["," slant ["," setwidth ["," encoding ["," hints]]]]]]
For example:
"helvetica [bitstream],12,bold,i,normal,iso8859-1,0"
Typically, at least the font name, and size must be given for normal font matching. As a special case, raw X11 fonts can also be passed, for example:
"9x15bold"
Finally, an old FOX 1.0 style font string may be passed as well:
"[helvetica] 90 700 1 1 0 0"
Return true if font has glyph for ch. Here, ch can either be an ordinal value, e.g.
aFont.hasChar?(?a)
or a string of length one (i.e. a single character), e.g.
aFont.hasChar?('a')
Returns the left-side bearing (the distance from the origin to the leftmost pixel in the character) for ch.
