lua mouse event handler

Question

I'd like to create an event handler in lua which can detect and locate mouse clicks (and ideally wheel movements) within a window, but can't find any way of doing it. Is there any way of doing it in lua, or would it be possible to create a hook somehow?

Events don't have to be reacted to immediately, so if there were some way of creating a table of mouse events which could subsequently be read from that would be fine.

I'm on ubuntu 14.04, and have Python available (if that helps). Thanks David

Not sure exactly what your requirements are, but there's a few options.

By far the easiest would be to use would be LOVE -- technically it's a sort of game framework that hosts Lua scripts but it displays a window and you can handle the events inside of the Lua runtime. Code to accomplish this would be roughly:

function love.mousepressed(x, y, button)
  -- do stuff here
end

More difficult but more Lua-centric might be something like wxLua which should allow you to create and manage a native window against the wxWidgets library (N.B. I have never gotten this to compile and run on OS X)

There's a number of bindings like wxLua to other GUI frameworks. There's a complete list over at the lua-users wiki.
