[WIN] RE: Win32lib: setting cursor in RichEdit

Matt,

I don't think I quite understand.

Do you mean load a file into the editor (RTF formatted, like I'm doing now)
and onKeyPress, pull all the data out as getRichText, use the cursor
position  from getIndex( RE ) with that position in the getRichText data,
colorize the data bounded by spaces left and right and reload as RTF? That's
a mighty big bunch of data to be moving around. Won't it take time? But it
sounds like it will work. For the IDE there is not that much data in the
editor at a time but for projecting the method into a general purpose
editor, one never knows how much there will be.

I appreciate your ideas.

Judith
