dynamic Button captions?

[bhnh]

Anyone know if there's a way to change the caption on a Button when it's pressed? I'm thinking of a Boolean-type situation, where clicking the Button alternates the Boolean state between true and false. So the caption would read "Click for true" or "Click for false" depending on the Boolean state. Many thanks.

Problem solved...

(
rollout test "test" (

button pressthis "Press for true"

on pressthis pressed do
(
   text1 = pressthis.text
   if text1 == "Press for true" then
   (
      pressthis.text = "Press for false"
   )
   else pressthis.text = "Press for true"
)
)
createdialog test
)

You can also toggle a boolean value rather than testing for the text - text tests are very slow in comparison to a boolean test.

I posted an example of just that (changing a button caption) not long ago, but I cant remember which thread it was in.

Jeezum! Just goes to show how closely I pay attention :roll: . Before seeing your edit I tried this, with success...

rollout test "test"
(
    button btn "Apples"
    local bState = false
    
    on btn pressed do
    (
        bState = not bState
        if bState == true then btn.caption = "Oranges"\
        else btn.caption = "Apples"
    )
)
createDialog test 200 50

Thanks, Steve!

Hehe - easy done Bruce. 🙂

Btw, you don't need the "= True" - it's a boolean value so just " if bState" (or "if not bState") is sufficient 😉

Cool. Thanks. I'm making such an effort to keep MXS syntax separated from ActionScript syntax in my head, I tend to overlook instances where they're the same.

I suppose this is obvious, but I just realized this method can also make labels dynamic...

rollout test "Dynamic Label"
(
    label lbl "Apples"
    button btn "Comparison"
    local Lstate = false
    
    on btn pressed do
    (
    Lstate = not Lstate
    if Lstate then lbl.text = "Oranges" else lbl.text = "Apples"
    )

)

createDialog test

Yep. You should be able to change any property that you can access, so you can enable/disable another button or group of items, reset the position of a progressbar, even move items around on the rollout (confusing for the user, but fun 😄 ), add items to drop-down lists - anything really which depends on a "what state am I in" type test.
