Fields

style: Style

Overall window background style (Part::MAIN).

header_color: Color

Background color for the header bar.

title_color: Color

Header title text color.

button_color: Color

Header button background color (Part::ITEMS).

button_text_color: Color

Implementations

impl Window

pub fn new(bounds: Rect, header_height: i32) -> Window

Create a window with the given outer bounds and header height.

Use DEFAULT_HEADER_HEIGHT when no specific height is needed.

pub fn set_title(&mut self, text: &str)

Set the window title displayed in the header bar.

pub fn title(&self) -> &str

Return the current window title.

pub fn add_header_button( &mut self, icon: Option<&str>, width: i32, ) -> WindowButtonId

Append an icon button to the header bar and return its WindowButtonId.

icon is an optional UTF-8 glyph or short string drawn inside the button. width is the button width in pixels.

pub fn last_button_pressed(&mut self) -> Option<WindowButtonId>

Return and clear the most recently activated header button id.

Returns None when no button was pressed since the last poll.

pub fn header_bounds(&self) -> Rect

Return the screen-space rect of the header bar.

pub fn content_bounds(&self) -> Rect

Return the screen-space rect of the content area (below the header).

pub fn set_font(&mut self, font: &'static dyn FontMetrics)

Assign the font used to render this widget (FONT-00 §5); resolves to FONT_6X10 when unset.

pub fn set_header_height(&mut self, h: i32)

Update the header height and recompute content bounds.

Apply the theme to the main style and direct widget-specific part colors.

impl Widget for Window

fn bounds(&self) -> Rect

Return the area this widget occupies relative to its parent.

fn widget_font_mut(&mut self) -> Option<&mut WidgetFont>

Expose this widget’s font slot for cascade-driven font resolution (FONT-05 §5.B).

fn set_bounds(&mut self, bounds: Rect)

Called by the LPAR-10 layout pass to notify this widget of its layout-computed bounds.

fn draw(&self, renderer: &mut dyn Renderer)
