Buttonbar Update or Refresh

[Greg Gammon]

I have a Buttonbar that I need to disable buttons on for certain tasks using a logical value.

Code: Select all

    DEFINE BUTTONBAR oBar OF oWnd _3D 
        DEFINE BUTTON OF oBar NAME 169  ACTION oWnd:end() MESSAGE "Quit" WHEN !lMenuLock
 

When lMenulock is .T., the button gray's out, but when lMenulock is changed to .F., the button does not reactivate.
I have tried oBtn:refresh() etc. but can't make this work.

Thanks for the help!

The easiest solution may be to just do an oBtn:disable()/oBtn:enable() whenever you change lMenuLock.

Yep! I just enable/disable the entire bar: oBar:enable() / oBar:disable()....perfect and simple.
Thanks AGAIN James

Greg,

try also oBar:AEvalWhen().

Enrico,

oBar:AEvalWhen()

What exactly does that do? Does it reevaluate the WHEN clauses for every button on the bar?

Yes, it should do that.
