Strange things, that there isn't in v.5.0.2 (windows version):
* message from console: procedure set-icon method in frame%: no clause matching
1 argument: (object:bitmap% ...) earlier it was possible and there is no
change in the help about this
* In DrRacket's console shift+home combination is returns the cursor to the
start of line and not to the start of editable area, as it was before
* I wrote a little code for testing strange behavior of tab-panel%:
--- start of file
#lang racket/gui
(define (make-editor) (new (class pasteboard% (super-new)
(define/override (on-default-event event) (when (send event
button-down? 'any) (display (list (send event get-x) (send event
get-y))))))))
(define (testing make-tab? tab-in-vp? make-canvas? canvas-in-tab?) (let*
([frame (new frame% [label "Testing 5.0.99.900"] [min-width 300] [min-height
200])] [vp (new vertical-panel% [parent frame])] [tabs (and
make-tab? (new tab-panel% [parent (if
tab-in-vp? vp frame)] [choices '("the first"
"the second" "the third")]))]) (when make-canvas? (new editor-canvas%
[parent (if (and tabs canvas-in-tab?) tabs vp)] [editor
(make-editor)])) (send* frame (center 'both) (show #t))))
--- end of file
Now, let's try it:
(testing #t #f #f #f), (testing #t #t #f #f) -> Ok(testing #t #f #t #f),
(testing #t #t #t #f) -> not pretty, but it is clear (in the sense, as in
previous versions)(testing #t #t #t #t), (testing #t #f #t #t) -> 1. Tabs
disappeared. 2. Appear empty space under canvas. It seems, canvas should be
moved down by a distance of the height of tabs 3. Click mouse on the canvas
has an effect only in upper part (where must be tabs).(testing #f #f #t #f) ->
canvas is Ok.
