Flow/wrap text into an irregular shape

Sure. You could calculate a table of left and right char counts on each line, since I guess the field and grc sizes do not change (?). And then place successive chars. You can still use keyDown (semi-pseudo):


on keyDown var
  put var into char nextCharLoc of me
end keyDown


Or something like that.  But you will have to first pad your entire field with spaces. If you take a new field and do this:


put "X" into char 5 of me


The "X" will go into the first char. Same with any additional ones; they will follow the existing text. Such a command will find the correct line:


put "X" into char 5 of line 4 of me


but not the correct char location. If the field is padded, though, it should work fine.

Thanks Craig. It might be simpler to just use a monospaced font, and know
beforehand how many chars will fit each line of text, and wrap accordingly.
