snapshot_child


Description:

public void snapshot_child (Widget child, Snapshot snapshot)

Snapshot the a child of this.

When a widget receives a call to the snapshot function, it must send synthetic `GtkWidget`Class.snapshot() calls to all children. This function provides a convenient way of doing this. A widget, when it receives a call to its `GtkWidget`Class.snapshot() function, calls snapshot_child once for each child, passing in the snapshot the widget received.

snapshot_child takes care of translating the origin of snapshot, and deciding whether the child needs to be snapshot.

This function does nothing for children that implement `GtkNative`.

Parameters:

this

a `GtkWidget`

child

a child of this

snapshot

Snapshot as passed to the widget. In particular, no calls to translate or other transform calls should have been made.
