hi, i am trying to rewrite a mind-mapping program (kdissert/semantik) in drscheme and then make it more flexible. <br> what
the application will need is a canvas with a lot of boxes with text in
them and edges connecting the boxes. occasionally i will need an
text-editor snip, to create a new box of text or edit an existing one.
and, the boxes of text need to be draggable.
<br> MrEd, right now has two types of editors - text and pastebox, and
both dont seem to support drawing operations. I am writing to ask if
anyone has implemented a canvas editor so far. or maybe, there is some
other way to implement this functionality? i tried drawing a
text-editor snip directly onto the dc of a canvas using draw, but that
didn't seem to work.
