How to show disable state of UIButton?

cocos2d-x C++
#1

I made some ui with CocoStudio 1.1.0.0.
and load it into Scene.
when i set uiButtonInstance->setEnable(false),
it disappear on screen, instead of showing disable state.

I found comment of UIWidget.setEnabled on cpp source says…

“true if the widget is enabled, widget may be touched and visible, false if the widget is disabled, widget cannot be touched and hidden.”

if so, when disable state is shown?

disable (bool containChildren=false)

Where is the method “->disable()” ?
I have the same problem with @volzh.

Is there any property with the meaning of “DISABLE” in common scence ?

Is it setBright() this makes no sense but may work for you…

In my UI for dynamic buttons I find ->removeFromParent() works well!

I only want to help you improve.

why setEnable false is not working ? and setBright is working? is it intended?

#15

Thanks for the setBright solution although this makes no sense at all!

There’s no disable(), it’s setEnabled(boolean).setBright(boolean)just changes the visual sprite basically.setEnabledcalledsetBright` anyway, so you don’t need to double up on that’.

I’ve got a related question, is it possible to disable a button but still have it swallow touches, as in if you disable a button, have the touch not touch the thing thats behind it? button->setSwallowTouches(true) doesn’t seem to do it, neither does button->setTouchEnabled(true) nor did button->setPropagateTouchEvents(false).

Looking at the source, Widget::onTouchBegan returns false before checking anything other than isVisible or isEnabled, so maybe I can’t without subclassing.

I have used setBright(false) when showing the disabled state of the Button. Basically button activates power-up and I need to add logic such that button remains disabled while power-up is on cooldown.
But there is a weird issue. When setBright(false) is called for first time, the button disappears from HUD . After cooldown gets over, button becomes visible again. Now if I activate the power-up, then setBright(false) works as intended and button becomes greyed and not invisible.

How do I fix this ?

I don’t really understand your problem. Do you have a selected texture?

#19

I do, do i follow this topic? I’m in the same situation, though i see this is quite old

I have a set texture but the button keeps the same image

solved. I forgot to add .png.

Yes it very well seems naive but we all make mistakes
