Disabled buttons?

[kpeters]

Hi ~

is it possible to disable buttons? If not, what is an easy way to convey button states to the user?

TIA,
Kai

Disable a button by changing its action facet.
You could show that by changing the color of the button (or other effects):

Code:

  active: does [print "b1 pressed"]    ;; function for active button
  inactive: none                             ;; action for diasbled button

view layout [
    b1: button "B1"
       [active]              ;; default action facet of active
 
    b2: button "b2" [
       b1/action: inactive    ;; set b1 inactive if pressed
       b1/effect/3: 0.0.0    ;; change b1's color gradient effect
       show b1                   ;; rerender b1
   ]
]
