Draw reference glyph ↩
This example shows a very simple tool which displays the current glyph in a system font at the bottom of the glyph window.
This is how the code works:
- an observer is added to the
drawevent - when the event is triggered, the tool uses the unicode value of the current glyph to get the corresponding character
- finally, if there is a character for the glyph, text properties (fill, font, font size) are set, and the text placed

# get the current glyph

# define a fill color
color = 0, 0, 0, 0.5
# make sure we have a character
if glyph is not None and glyph.unicode is not None and glyph.unicode < 0xFFFF:
# get character for glyph
t = unichr(glyph.unicode)
# draw reference glyph

stroke(None)
fill(*color)
text(t, (glyph.width + 10, 10))
# turn tool on
