type State = State<<N as Iterator>::Item>

State to be stored within the Uis widget cache.

type Style = Style

Every widget is required to have its own associated Style type. This type is intended to contain high-level styling information for the widget that can be optionally specified by a user of the widget.

type Event = SessionEvents<<N as Iterator>::Item>

The type of event yielded by the widget, returned via the Widget::set function.

fn init_state(
    &self,
    id_gen: Generator<'_>
) -> <Graph<'a, N, E> as Widget>::State

Return the initial State of the Widget.

fn style(&self) -> <Graph<'a, N, E> as Widget>::Style

Return the styling of the widget.

fn update(
    self,
    args: UpdateArgs<'_, '_, '_, '_, Graph<'a, N, E>>
) -> <Graph<'a, N, E> as Widget>::Event

Update our Widget's unique Widget::State via the State wrapper type (the state field within the UpdateArgs).

fn default_x_position(&self, ui: &Ui) -> Position

The default Position for the widget along the x axis.

fn default_y_position(&self, ui: &Ui) -> Position

The default Position for the widget along the y axis.

fn default_x_dimension(&self, ui: &Ui) -> Dimension

The default width for the Widget.

fn default_y_dimension(&self, ui: &Ui) -> Dimension

The default height of the widget.

fn drag_area(
    &self,
    _dim: [f64; 2],
    _style: &Self::Style,
    _theme: &Theme
) -> Option<Rect>

If the widget is draggable, implement this method and return the position and dimensions of the draggable space. The position should be relative to the center of the widget.

fn kid_area(&self, args: KidAreaArgs<'_, Self>) -> KidArea

The area on which child widgets will be placed when using the Place Position methods.

fn is_over(&self) -> fn(&Container, [f64; 2], &Theme) -> IsOver

Returns either of the following:

fn parent(self, parent_id: NodeIndex<u32>) -> Self

Set the parent widget for this Widget by passing the WidgetId of the parent.

fn no_parent(self) -> Self

Specify that this widget has no parent widgets.

fn place_on_kid_area(self, b: bool) -> Self

Set whether or not the Widget should be placed on the kid_area.

fn graphics_for(self, id: NodeIndex<u32>) -> Self

Indicates that the Widget is used as a non-interactive graphical element for some other widget.

fn floating(self, is_floating: bool) -> Self

Set whether or not the widget is floating (the default is false). A typical example of a floating widget would be a pop-up or alert window.

fn crop_kids(self) -> Self

Indicates that all widgets who are children of this widget should be cropped to the kid_area of this widget.

fn scroll_kids(self) -> Self

Makes the widget's KidArea scrollable.

fn scroll_kids_vertically(self) -> Self

Makes the widget's KidArea scrollable.

fn scroll_kids_horizontally(self) -> Self

    F: FnOnce(Self) -> Self, 

A builder method that "lifts" the Widget through the given build function.

fn and_mut<F>(self, mutate: F) -> Self where
    F: FnOnce(&mut Self), 

A builder method that mutates the Widget with the given mutate function.

fn and_if<F>(self, cond: bool, build: F) -> Self where
    F: FnOnce(Self) -> Self, 

A method that conditionally builds the Widget with the given build function.

fn and_then<T, F>(self, maybe: Option<T>, build: F) -> Self where
