Functions

bind_state

Helper for declaring state properties that are controlled by a variable.

bind_state_init

Helper for declaring state properties that are controlled by a variable.

border_node

Creates a border node that delegates rendering to a border_visual and manages the border_offsets coordinating with the other borders of the widget.

event_state

Helper for declaring state properties that depend on a single event.

event_state2

Helper for declaring state properties that depend on two other event states.

event_state3

Helper for declaring state properties that depend on three other event states.

event_state4

Helper for declaring state properties that depend on four other event states.

extend_widget

Create a widget node that wraps the widget with any number of other non-widget nodes and still delegates with_context to the widget.

fill_node

Transforms and clips the content node according with the default widget border align behavior.

interactive_node

Create a node that controls interaction for all widgets inside node.

list_presenter

Node list that presents list using item_fn for each new list item.

list_presenter_from_iter

Node list that presents list using item_fn for each list item.

match_node

Creates a node that is implemented as a closure that matches over UiNodeOp and delegates to another child node.

match_node_leaf

Creates a node that is implemented as a closure that matches over UiNodeOp and does not delegate to any child node.

match_widget

Creates a widget that is implemented as a closure that matches over UiNodeOp and delegates to another child widget.

presenter

Node that presents data using wgt_fn.

presenter_opt

Node that presents data using wgt_fn if data is available, otherwise presents nil.
