FlowBoxChild

class FlowBoxChild(**properties: Any)

Superclasses: Widget, InitiallyUnowned, Object

Implemented Interfaces: Accessible, Buildable, ConstraintTarget

GtkFlowBoxChild is the kind of widget that can be added to a GtkFlowBox.

Constructors

class FlowBoxChild

classmethod new() → Widget

Creates a new GtkFlowBoxChild.

This should only be used as a child of a GtkFlowBox.

Methods

class FlowBoxChild

changed() → None

Marks child as changed, causing any state that depends on this to be updated.

This affects sorting and filtering.

Note that calls to this method must be in sync with the data used for the sorting and filtering functions. For instance, if the list is mirroring some external data set, and two children changed in the external data set when you call changed() on the first child, the sort function must only read the new data for the first of the two changed children, otherwise the resorting of the children will be wrong.

This generally means that if you don’t fully control the data model, you have to duplicate the data that affects the sorting and filtering functions into the widgets themselves.

Another alternative is to call invalidate_sort on any model change, but that is more expensive.

get_child() → Widget | None

Gets the child widget of self.

get_index() → int

Gets the current index of the child in its GtkFlowBox container.

is_selected() → bool

Returns whether the child is currently selected in its GtkFlowBox container.

set_child(child: Widget | None = None) → None

Sets the child widget of self.

Parameters:

child – the child widget

Properties

class FlowBoxChild

props.child: Widget

The type of the None singleton.

Signals

class FlowBoxChild.signals

activate() → None

Emitted when the user activates a child widget in a GtkFlowBox.

This can happen either by clicking or double-clicking, or via a keybinding.

This is a keybinding signal, but it can be used by applications for their own purposes.

The default bindings are Space and Enter.

do_activate() → None
