Struct nannou::ui::prelude::widget::primitive::line::Line

pub struct Line {
    pub common: CommonBuilder,
    pub start: [f64; 2],
    pub end: [f64; 2],
    pub style: Style,
    pub should_centre_points: bool,
}

A simple, non-interactive widget for drawing a single straight Line.

Fields

common: CommonBuilder

Data necessary and common for all widget builder types.

start: [f64; 2]

The start of the line.

end: [f64; 2]

The end of the line.

style: Style

Unique styling.

should_centre_points: bool

Whether or not the line should be automatically centred to the widget position.

Implementations

impl Line

pub fn styled(start: [f64; 2], end: [f64; 2], style: Style) -> Line

Build a new Line widget with the given style.

pub fn new(start: [f64; 2], end: [f64; 2]) -> Line

Build a new default Line widget.

pub fn abs(start: [f64; 2], end: [f64; 2]) -> Line

Build a new Line whose bounding box is fit to the absolute co-ordinates of the line points.

If you would rather centre the start and end to the middle of the bounding box, use Line::centred instead.

pub fn abs_styled(start: [f64; 2], end: [f64; 2], style: Style) -> Line

The same as Line::abs but with the given style.

pub fn centred(start: [f64; 2], end: [f64; 2]) -> Line

Build a new Line and shift the location of the start and end points so that the centre of their bounding rectangle lies at the position determined by the layout for the Line widget.

This is useful if your points simply describe the line’s angle and magnitude, and you want to position them using conrod’s auto-layout or Positionable methods.

If you would rather centre the bounding box to the points, use Line::abs instead.

pub fn centred_styled(start: [f64; 2], end: [f64; 2], style: Style) -> Line

The same as Line::centred but with the given style.

pub fn thickness(self, thickness: f64) -> Line

The thickness or width of the Line.

Use this instead of Positionable::width for the thickness of the Line, as width and height refer to the dimensions of the bounding rectangle.

pub fn solid(self) -> Line

Make a solid line.

pub fn dashed(self) -> Line

Make a line with a Dashed pattern.

pub fn dotted(self) -> Line

Make a line with a Dotted pattern.

Trait Implementations

impl Copy for Line

impl Debug for Line

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Widget for Line

type State = State

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 = ()

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

pub fn init_state(&self, Generator<'_>) -> <Line as Widget>::State

Return the initial State of the Widget.

pub fn style(&self) -> <Line as Widget>::Style

Return the styling of the widget.

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

Returns either of the following:

pub fn update(
    self,
    args: UpdateArgs<'_, '_, '_, '_, Line>
) -> <Line as Widget>::Event

Update the state of the Line.

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

The default Position for the widget along the x axis.

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

The default Position for the widget along the y axis.

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

The default width for the Widget.

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

The default height of the widget.

pub 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.

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

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

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

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

pub fn no_parent(self) -> Self

Specify that this widget has no parent widgets.

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

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

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

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

pub 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.

pub 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.

pub fn scroll_kids(self) -> Self

Makes the widget’s KidArea scrollable.

pub fn scroll_kids_vertically(self) -> Self

Makes the widget’s KidArea scrollable.

pub fn scroll_kids_horizontally(self) -> Self

Set whether or not the widget’s KidArea is scrollable (the default is false).

pub fn and<F>(self, build: F) -> Self where
    F: FnOnce(Self) -> Self, 

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

pub 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.

pub 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.

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

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

pub fn set(self, id: NodeIndex<u32>, ui_cell: &'a mut UiCell<'b>) -> Self::Event

Note: There should be no need to override this method.
