Struct zaplib_components::Background

pub struct Background { /* private fields */ }

Implementations

impl Background

pub fn set_color(&mut self, cx: &mut Cx, color: Vec4)

pub fn with_draw_depth(self, draw_depth: f32) -> Self

pub fn with_radius(self, radius: f32) -> Self

pub fn begin_draw(
    &mut self,
    cx: &mut Cx,
    width: Width,
    height: Height,
    color: Vec4
)

Calls Self::draw without having to pass in a [Rect] immediately. We will overwrite the coordinates in the shader directly in Background::end_draw. This is useful for if you need to draw a quad in the background, since in that case you have to draw the quad first before drawing the content (otherwise it would sit on top of the content!), but you might not know the dimensions yet. In Background::end_draw we get the dimensions of the content from Cx::end_row and set this directly using Area::get_first_mut.

pub fn end_draw(&mut self, cx: &mut Cx)

See Background::begin_draw.

pub fn area(&self) -> Area

Get the Area.

pub fn set_area(&mut self, area: Area)

Manually set the Area.

pub fn draw(&mut self, cx: &mut Cx, rect: Rect, color: Vec4)

Draw the background.

pub fn draw_with_scroll_sticky(&mut self, cx: &mut Cx, rect: Rect, color: Vec4)

Draw the background, but make it sticky with respect to scrolling. Not typically recommended.

Trait Implementations

impl Default for Background

fn default() -> Background

Returns the “default value” for a type.
