This item has no description.

Published property colorbackground: colorty read getcolorbackground write setcolorbackground stored iscolorbackgroundstored default cl_default;

Fill color of the glyph cells, not including extraspace. Ignored (forced to transparent) while shadow_color or gloss_color is not cl_none.

Published property shadow_color: colorty read getshadow_color write setshadow_color stored isshadow_colorstored default cl_none;

Color of the glyph shadow, drawn offset by shadow_shiftx and shadow_shifty. When not cl_none, the text is drawn in two passes (shadow, then glyph) and colorbackground is ignored.

Published property width: integer read getwidth write setwidth stored iswidthstored default 0;

This item has no description.

Published property extraspace: integer read getextraspace write setextraspace stored isextraspacestored default 0;

Vertical space, in pixels, between the glyph cells of adjacent text rows. Negative values cause the cells to overlap.

Published property style: fontstylesty read getstyle write setstyle stored isstylestored default [];

This item has no description.

Published property name: string read getname write setname stored isnamestored;

This item has no description.

Published property charset: string read getcharset write setcharset stored ischarsetstored;

Changes the font to the nearest one containing the given encoding. No change is made if no font matches the requested encoding. Do not set this away from its default (iso10646, i.e. Unicode) in normal use: MSEgui's internal text representation is UCS2, and iso10646 is the only encoding compatible with it.

Published property options: fontoptionsty read getoptions write setoptions stored isoptionsstored default [];

Selects the font by category rather than by name: foo_helvetica (sans), foo_roman (serif), foo_script and foo_decorative choose the nearest font in that category; foo_fixed/foo_proportional choose the nearest mono/proportionally spaced font. A foo_* selection overrides one made with name; if it fails, the nearest sans font is used. foo_antialiased/foo_nonantialiased are Linux-only and toggle Xft antialiasing.

Published property xscale: real read getxscale write setxscale stored isxscalestored;

Published property localprops: fontlocalpropsty read flocalprops write setlocalprops;
