More events and states for fabric.Control

[hamzawain7]

I want to render buttons slightly differently on Hover and Active state. I think that is not achievable with current api.

My proposition is to add mouseOverHandler, mouseOutHandler functions and isActive property

Why using fabricjs for things like buttons? does it make sense?

Anyway you already have mouseenter and mouseleave events ( i can't remember the exact names right now, but are in the docs and events demo )

Sorry i meant i want to render the controls slightly differently on hover/active states. By button i meant a hovering delete button for an item like in your demo (http://fabricjs.com/custom-control-render).

There isn't any mouseenter/mouseleave event in the control.class (would be nice to have those). I tried using the existing provided mousedown and mouseup for detecting whether a control was active but that can't be used as mouseup doesn't fire if mouse is outside the control

Sorry for not replying for a long time, in the hover event, there is always a reference to the control currently hovered, is the same reference we use to change the cursor style.
Object.__corner keep the value of the hovered control.
At that point you can change control properties to look different.
