Drag and Drop Icons

[static_recharge]

Hey everyone!

So I'm trying to make an add-on that includes various icons being dragabble and dropable, much like how the ingame skill manager works. Basic requirements are: click and drag to new slot, single clicking without dragging will activate the button instead, hovering over the item will enable the outline glow just like the skills window.

I've had a look at the source code for the skill manager but I haven't been able to follow along to get the results that I'm looking for. If anyone can provide even a dumbed down version that I can learn from I would be greatly appreciated.

If anyone needs more clarification, I would set up a grid, like the skill bar, and textures would represet the various "abilities" or items on the bar. These items can be moved around, right clicked for context menus or clicked on to activate their designated item.

Thanks in advance!
