Simpler Event Registration - IUIEventHandler, vs. 6 UnityEvents.

[najak3d]

Rather than forcing the more tedious (and computationally/memory intensive) method of registering and deregistering for each event PER control -- i.e. Click, Hovered, Unhovered, Press, Release, Cancel.

Instead each UIControl should have one field, "IUEventHandler EventHandler", as follows:

[FLAGS]
enum GestureTypes : byte  { _None = 0,  Hover = 1,  Unhovered = 2, AllHover = 3, Press = 4, Release = 8, Cancel = 16, Clicked = 32, ALL = 63 }

interface IUEventHandler
{
GestureTypes GesturesHandled {get; }
HandleClick(...)
HandleHover(....)
HandleUnhover(...)
.....
}

Or to make this interface easier to implement, just have 1 main method, as follows:

interface IUEventHandler
{
GestureTypes GesturesHandled {get; }
HandleUIEvent(GestureType gType, args...)
.....
}

Then, hooking up Controls can be "automated" (set in the Prefab itself) or set manually with a single C# line of code.

Then you can decide whether or not have a shared-singleton handler - which acts like a centralized event dispatcher -- OR you can assign individual Handlers to any control, that is specific to that Control, or that Control class/type.

IMO, this would be MUCH better than having 6 separate event handler methods for each control that have to individually be Registered and Removed for each Control Enable/Disable.
