Best way to disable a widget?

[Shifty Geezer]

I have a UIToggle script to show/hide a widget that's working fine. However, the controls within that widget are still active even when hidden. I guess disabling the boxcollider is the easiest way to deactivate it, but how does one connect that behaviour in with the Toggle script?

I've found UIWidget.SetActive to en/disable child objects. I've also found UIToggledObjects which en/disables based on toggle, but that does it immediately without waiting for the transitions.

Controls within widgets? Eh? Not sure what you mean there.

NGUITools.SetActive is what should be used to enable/disable objects. Check the "Tabs" example. It enables and disables entire pages of widgets via UIToggles to create a tabbed window.

Yeah, I got SetActive working, but that immediately disables the controls before they can fade.

I have a slider and a scrollview, and only one is active at a time. Pressing a button on one control panel disables the slider and enables the scrollview. These currently fade in/out nicely using UIToggle and smooth transition. I need to apply the NGUITools.SetActive method on completion of the automatically generated fade. That might require a manual fade tween, but I still don't understand how to use the Notify option. Dragging objects only presents a limited set of methods that can be called and I cannot call my own custom methods.

All tweens have an onFinished delegate you can set to your custom function that will do whatever you wish inside, including calling SetActive(false). UIPlayTween also has this option built-in.

How do I get my custom function to appear in the Notify selection box? I've gone over C# and Unity tutes on delegates and looked through the UI code and can't work this out. When I drag a sprite object onto the Notify box, I don't see what makes UISprite.resizeCollider appear as an option but not other functions or custom functions.

[ArenMook]

NGUI's EventDelegate expects a public void FuncName () signature for it to show up in the Notify list. Note the "public", void return type, and no parameters.

[Shifty Geezer]

Yeah, I noticed that. So I added a method in the UISprite.cs script...

1. public void TryThis(){
2.         // an attempt at a delegate function
3.         print ("Delegated!");
4. }

...but it isn't listed.

Hey, it's working!! Do I have to restart Unity or something for it to appear?? Maybe I just didn't notice it in the list?  Anyway, all's good now. Thanks.

You just need to wait for the scripts to re-compile, and it will show up.
