So I'm trying to write a social networking application using Racket's
GUI toolkit. Most if it is going well, but the tricky thing is that the
user content has rich text (coming from HTML)... a simple message% won't
do, since I need to insert links and text and images and etc, but
luckily the editor% tools seem to be working well enough. I'm doing
something like the following:
(inherit begin-edit-sequence end-edit-sequence
get-max-width find-snip position-location)
(define immutable? #f)
(set! immutable? #t))
(set! immutable? #f))
(define/augment (can-insert? start len)
(define/augment (can-delete? start len)
(define a-frame (new frame% [label "foo"]))
(define ec (new editor-canvas%
[style '(no-scroll no-vscroll)]))
(define a-text (new freezable-text%
(send ec set-editor text)
(send a-text insert "Blah blah blah\n\nblah blah")
(send a-text freeze!)
So now I've got some text that renders okay, it line wraps, etc etc.
The problem is, I want to add a panel with a bunch of these, and I want
each of these "rich text" things to be exactly the height of their
contents. I can't figure out how to do it... either I have
stretchable-text set to #t and I'm stuck with whatever size it scales
to, or I set stretchable-text to #f and the rich text canvas is only a
few pixels high... not enough to see any content.
I'm going to be blitting a "timeline", so the behavior I'd really like
is to have each of these be the appropriate height of their content, and
the panel to have hscroll auto-enabled so that can be scrolled if
I thought about setting the minimum height, but I can't seem to figure
out how to get the value of the full "text contents" height in pixels...
Any ideas? Thanks!
