Connect to Map signal.

Emitted when widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with [gtk.widget.Widget.visible]) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of [gtk.widget.Widget.unmap].

Parameters

`callback`	signal callback delegate or function to connect `void callback(gtk.widget.Widget widget)` `widget` the instance the signal is connected to (optional)
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
