This lets you know we are skipping events in the case you need to do something pro-actively with the GUI

This processes any pending messages.

For each event from the GUI, this needs to call the appropriate event method for the object involved with the event. This needs to create/support the following Locana events for the object related to the frame receiving the event, see Levent for more details.

• :on_mouse_ldn => "when the left mouse button is clicked, levent[:x] and levent[:y] contain the mouse position",
• :on_mouse_lup => "when the left mouse button is released, levent[:x] and levent[:y] contain the mouse position",
• :on_mouse_ldbl => "when the left mouse button is double clicked, levent[:x] and levent[:y] contain the mouse position",
• :on_mouse_rdn => "when the right mouse button is clicked, levent[:x] and levent[:y] contain the mouse position",
• :on_mouse_rup => "when the right mouse button is released, levent[:x] and levent[:y] contain the mouse position",
