Struct rstubs::device::cga::Window

pub struct Window {
    cursor: (u8, u8),
    hw_cursor: bool,
    rect: Rect,
    pub style: Attribute,
}

The screen represents the cga screen or a part of it.

This class provides an interface to access the screen in text mode (also known as CGA mode), with access directly on the hardware level, i.e. the video memory and the I/O ports of the graphics card.

There can be multiple screes to different areas of the cga. However, only one of them should control the hw_cursor at the same time.

Fields

cursor: (u8, u8)

Cursor position

hw_cursor: bool

If the hardware cursor should be used

rect: Rect

Size of the screen

style: Attribute

Style

Implementations

impl Window

pub const fn whole() -> Window

Create a window filling the whole screen.

pub const fn new(rect: Rect) -> Window

Create a window with the given bounds.

pub const fn with_hw_cursor(self) -> Self

Configure the window to use the hardware cursor.

pub const fn with_style(self, attr: Attribute) -> Self

Configures the screen to use the given style.

pub fn clear(&mut self)

Clear the whole screen.

pub fn fill(&mut self, cell: Cell)

Fill the whole screen with the given character.

pub fn set_cursor(&mut self, pos: (u8, u8))

Move the cursor to pos

pub fn get_cursor(&mut self) -> (u8, u8)

Returns the cursor position.

fn set(&mut self, pos: (u8, u8), cell: Cell)

Trait Implementations

impl Debug for Window

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

Formats the value using the given formatter.

impl Write for Window

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>
