Hi Lutz,
How can i update an image-label with a new image...?
I trief enable disable refesh etc...
Im unable to get the image refreshed...
Btw..it would be nice if the icon-path would also be a i.e. (read-file ....) action...
instead of reading from disk it reads from text directly..
Regards,
Norman.
This worked for me:
(gs:panel 'ThePanel)
(gs:image-label 'aImage "/local/newLISP128.png")
(gs:toggle-button 'Toggle 'toggle-action "toggle")
(gs:add-to 'ThePanel 'aImage 'Toggle)
(gs:add-to 'TestFrame 'ThePanel)
(gs:set-visible 'TestFrame true)
(define (toggle-action id flag)
(if flag
(gs:set-icon 'aImage "/local/newLISP32.png")
(gs:set-icon 'aImage "/local/newLISP128.png"))
)

Aha oke.. Im just wondering if the set-icon does a refresh of the label
or if the toggle button does this... I tried this yesterday but not with
a toggle button..could not get is working... Ill try it again...
Nope.. the set-icon only does not refresh the image-label...
This is odd...
The problem is.. My image is every 5 seconds different but with
the same name ;-) So i want an update of the image every 5 seconds
without user interaction...

Wait until the 2D graphics stuff is implemented. It gives better control for animating and otherwise handling images.
My example works beccause pressing the toggle button fources a repaint of the window, which fources a repaint of the label. With the 2D stuff you will have repaint behaviour under program control.
The currently implemented facilities aren't really meant for this.
