-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list,
I have a couple of issues with current racket/gui behavior. I have created the following test-case: #lang racket/gui (define list-editor% (class vertical-panel% (init init-values parent) (super-new (parent parent)) (define (insert-item val) (let* ((v (new vertical-panel% (parent this) )) ;** ; (ins (new button% (parent v) (label "insert"))) ) (new text-field% (parent this) (label "") (init-value val))) ) ; (send this begin-container-sequence) (for ((v init-values)) (insert-item v)) ; (send this end-container-sequence) )) ; end define class (define root (new frame% (label "List Editor"))) (new list-editor% (parent root) (init-values '("1" "2" "3"))) (send root show #t) 1) If you run the program like this, then 3 wide text-fields are created each with lots of empty space on top of it. The empty space shouldn't be there. 2) Now uncomment the first commented line, the one that creates buttons and run again. The texfields are now narrow and instead of empty space there are now buttons. This case seems fine. 3) Now uncomment the begin/end-container-sequence lines and run again. Suddenly the textfields are wide again and there is extra vertical space in between the textfields and buttons. I don't think that begin/end-container-sequence should ever influence the final result, since they are only to prevent flickering due to too frequent on-screen resizing. 4) Finally, it seems that (style '(border)) doesn't work for me when I add it on the line marked ** as a property of the vertical-panel. All this (tested) on Linux.
