Class Details¶

class Gtk.CustomLayout(**kwargs)¶

Bases:: Gtk.LayoutManager
Abstract:: No
Structure:: Gtk.CustomLayoutClass

Uses closures for size negotiation.

A GtkCustomLayout uses closures matching to the old GtkWidget virtual functions for size negotiation, as a convenience API to ease the porting towards the corresponding GtkLayoutManager virtual functions.

classmethod new(request_mode, measure, allocate)[source]¶

Parameters:

request_mode (Gtk.CustomRequestModeFunc or None) – a function to retrieve the GtkSizeRequestMode of the widget using the layout; the default request mode is Gtk.SizeRequestMode.CONSTANT_SIZE
measure (Gtk.CustomMeasureFunc) – a function to measure the widget using the layout manager
allocate (Gtk.CustomAllocateFunc) – a function to allocate the children of the widget using the layout manager

Returns:

the newly created GtkCustomLayout

Return type:

Gtk.LayoutManager

Creates a new legacy layout manager.

Legacy layout managers map to the old GtkWidget size negotiation virtual functions, and are meant to be used during the transition from layout containers to layout manager delegates.
