-- Simple immediate-mode buttons with (currently) just an onpress1 handler for
-- the left button.
--
-- Buttons can nest in principle, though I haven't actually used that yet.
--
-- Don't rely on the order in which handlers are run. Within any widget, all
-- applicable button handlers will run. If _any_ of them returns true, the
-- event will continue to propagate elsewhere in the widget.
-- draw button and queue up event handlers
function button(State, name, params)
if params.bg then
love.graphics.setColor(params.bg.r, params.bg.g, params.bg.b, params.bg.a)
love.graphics.rectangle('fill', params.x,params.y, params.w,params.h, 5,5)
end
if params.icon then params.icon(params) end
table.insert(State.button_handlers, params)
end
