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 that presents list using item_fn for each new 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_node_list
  Creates a node that is implemented as a closure that matches over UiNodeOp and delegates to multiple children nodes in a list.
• match_node_typed
  Like match_node, but does not change the child type when build with dyn_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.
• widget_state_get_state
  Helper for declaring state getter properties that are controlled by values in the widget state map.
• widget_state_is_state
  Helper for declaring state properties that are controlled by values in the widget state map.
• with_context_blend
  Helper for declaring widgets that are recontextualized to take in some of the context of an original parent.
• with_context_local
  Helper for declaring nodes that sets a context local value.
• with_context_local_init
  Helper for declaring nodes that sets a context local value generated on init.
• with_context_var
  Helper for declaring properties that sets a context var.
• with_context_var_init
  Helper for declaring properties that sets a context var to a value generated on init.
• with_index_len_node
  Helper for a property that gets the index of the widget in the parent panel and the number of children.
• with_index_node
  Helper for a property that gets the index of the widget in the parent panel.
• with_rev_index_node
  Helper for a property that gets the reverse index of the widget in the parent panel.
• with_widget_state
  Helper for declaring properties that set the widget state.
• with_widget_state_modify
  Helper for declaring properties that set the widget state with a custom closure.
