How to disable a DirectButton

Scripting Issues
1

Hi,

I use DirectButton in my application. I saw in the doc there is a ‘disabled’ state, but I didn’t find how to change the button’s state.

Thanks.

hmm… I’m not sure, but you can try either myButton.disableEdit() or myButton.setState…

I already tried these 2 funcs and it didn’t do anything.
The problem with setState is that it doesn’t take any arguments to specify the wanted state, so it’s a little strange.

DirectButton is implemented in Python, which doesn’t have enable/disable state toggle. But it’s C++ class, PGButton, which inherits from PGItem does have this ability.

DB.node().setActive(0)

Actually, the DirectButton class does support the enabled state toggle. It’s set via the ‘state’ member:

button['state'] = DGG.DISABLED
button['state'] = DGG.NORMAL

Thank you, it works.

Somehow I can’t seem to get this to work properly, when I use it like that, changing the word button to my button, or anyword all give errors, and about DGG it says it’s not defined. Could you make a short example please on how to use it when I’d name my button 'start’for example?

Many thanks in advance.

import direct.directbase.DirectStart
from direct.showbase.DirectObject import DirectObject
from direct.gui.DirectGui import *

class ButtonApplication(DirectObject):
  def __init__(self):
    self.b = DirectButton(text = ("Normal",
      "Click", "Over", "Disabled"))
    self.accept("f1", self.enable)
    self.accept("f2", self.disable)

  def enable(self):
    self.b['state'] = DGG.NORMAL

  def disable(self):
    self.b['state'] = DGG.DISABLED 

ba = ButtonApplication()

run()

With F1 and F2 you may enable/disable the button. Hope that helps.

Why so complicated? state=1 enables the button, state=0 disables it. I used it a lot for my menu stuff…
