## SHOW_CB

Called right after the dialog is showed, hidden, maximized, minimized or restored from minimized/maximized. This callback is called when those actions were performed by the user or programmatically by the application.

### Callback

    int function(Ihandle *ih, int state); [in C]
    ih:show_cb(state: number) -> (ret: number) [in Lua]

ih: identifier of the element that activated the event.
state: indicates which of the following situations generated the event:

> IUP_HIDE (since 3.0)
> IUP_SHOW
> IUP_RESTORE (was minimized or maximized)
> IUP_MINIMIZE
> IUP_MAXIMIZE (since 3.0) (not received in Motif when activated from the maximize button)

Returns: IUP_CLOSE will be processed.
