Hi Lutz,
How do I change the "PRESSED or TOGGLE" color on a button?
Its currently always the color from the look-and-feel default. (it seems)
small remark ->
Toggle-button is unable to handle "" for an empty button text whereas
button does... for toggle-button the text is always "..." when using "".
Bug ->
There is a bug in toggle-button... the code below
shows me sometimed garbage in the text when using "" instead of " ".
That is together with the gs:set-size... odd...
execute this code, and then without the gs:set-font..
On linux i see garbage as text..
sometimes this hapens and sometimes not?? odd to
reproduce...
(gs:init)
(gs:set-look-and-feel "javax.swing.plaf.metal.MetalLookAndFeel")
(gs:frame 'F1 200 200 500 500 "test")
(gs:set-grid-layout 'F1 1 1 1 1 )
(gs:panel 'BP)
(gs:set-background 'BP 0 0 0)
(dotimes (x leds)
(set 'b (sym (append "B" (string x))))
(gs:toggle-button b 'nix "" true)
(gs:set-font b "Sans Serif" "1" )
(gs:set-background b 0 0 0)
(gs:set-foreground b 1 1 1 )
(gs:set-size b 70 70)
(gs:add-to 'BP b))
(gs:add-to 'F1 'BP)
(gs:set-visible 'F1 true)

The Toggle-button Text bug is a string int mixup!
when using font size "1" instead of 1 its going wrong...
also the pressed-state color probably cant be changed when using the JAVA look-and-feels...
For linux you can though change the MOTIF look and feel colors from the Motif config file on Linux....!
For the GTK Metal etc.. it wont work probably... i think...

Yes, look-and-feel deafults seem always to overwrite the toggle-button color, nothing we can do :-( But you could try to set an icon on a toggle-botton using gs:set-icon and gs:set-pressed-icon. Or you could use image buttons and keep track of a toggle state yourself.

As mentioned yesterday for set-text in gs:frame, empty strings cannot be used (not to be fixed soon) use empty spaces inside the string when doing gs:set-text or specifying text in general. Do not use ever empty strings or text in widgets use " " a space embedded in quotes instead.

There should be a 'properties' file somewhere in your Java installation where you might be able to change these things.

To allow empty strings "" in the GU server interface the behavior of the newLISP function base64-enc has to be changed. Currently base64-enc returns "" when fed "" it should return "====" instead, which will be decoded as "" by base64-dec. This change will not happen until 9.1.9.
