pub struct Obj { /* private fields */ }

Generic LVGL object.

This is the parent object of all widget types. It stores the native LVGL raw pointer.

Trait Implementations

impl Default for Obj

fn default() -> Self

Returns the “default value” for a type.

impl NativeObject for Obj

fn raw(&self) -> LvResult<NonNull<lv_obj_t>>

Provide common way to access to the underlying native object pointer.

impl Widget for Obj

type SpecialEvent = u32

type Part = Part

fn from_raw(raw: NonNull<lv_obj_t>) -> Self

Construct an instance of the object from a raw pointer.

fn add_style(&mut self, part: Self::Part, style: &mut Style) -> LvResult<()>

Adds a Style to a given widget.

fn set_pos(&mut self, x: i16, y: i16) -> LvResult<()>

Sets a widget’s position relative to its parent.

fn set_size(&mut self, w: i16, h: i16) -> LvResult<()>

Sets a widget’s size. Alternatively, use set_width() and set_height().

fn set_width(&mut self, w: u32) -> LvResult<()>

Sets a widget’s width. Alternatively, use set_size().

fn set_height(&mut self, h: u32) -> LvResult<()>

Sets a widget’s height. Alternatively, use set_size().

fn set_align(&mut self, align: Align, x_mod: i32, y_mod: i32) -> LvResult<()>

Sets a widget’s align relative to its parent along with an offset.
