Struct bevy::window::Window

pub struct Window {

    pub cursor: Cursor,
    pub present_mode: PresentMode,
    pub mode: WindowMode,
    pub position: WindowPosition,
    pub resolution: WindowResolution,
    pub title: String,
    pub name: Option<String>,

    pub resize_constraints: WindowResizeConstraints,

}

The defining Component for window entities, storing information about how it should appear and behave.

Each window corresponds to an entity, and is uniquely identified by the value of their Entity. When the Window component is added to an entity, a new window will be opened. When it is removed or the entity is despawned, the window will close.

The primary window entity (and the corresponding window) is spawned by default by WindowPlugin and is marked with the PrimaryWindow component.

This component is synchronized with winit through bevy_winit: it will reflect the current state of the window and can be modified to change this state.

Example

Because this component is synchronized with winit, it can be used to perform OS-integrated windowing operations. For example, here’s a simple system to change the cursor type:

fn change_cursor(mut windows: Query<&mut Window, With<PrimaryWindow>>) {
    // Query returns one window typically.
    for mut window in windows.iter_mut() {
        window.cursor.icon = CursorIcon::Wait;
    }
}

Fields

cursor: Cursor

The cursor of this window.

present_mode: PresentMode

What presentation mode to give the window.

mode: WindowMode

Which fullscreen or windowing mode should be used.

position: WindowPosition

Where the window should be placed.

resolution: WindowResolution

What resolution the window should have.

title: String

Stores the title of the window.

name: Option<String>

Stores the application ID (on Wayland), WM_CLASS (on X11) or window class name (on Windows) of the window.

For details about application ID conventions, see the Desktop Entry Spec. For details about WM_CLASS, see the X11 Manual Pages. For details about Windows’s window class names, see About Window Classes.

Platform-specific

• Windows: Can only be set while building the window, setting the window’s window class name.
• Wayland: Can only be set while building the window, setting the window’s application ID.
• X11: Can only be set while building the window, setting the window’s WM_CLASS.
• macOS, iOS, Android, and Web: not applicable.

Notes: Changing this field during runtime will have no effect for now.

composite_alpha_mode: CompositeAlphaMode

How the alpha channel of textures should be handled while compositing.

resize_constraints: WindowResizeConstraints

The limits of the window’s logical size (found in its resolution) when resizing.

resizable: bool

Should the window be resizable?

Note: This does not stop the program from fullscreening/setting the size programmatically.

enabled_buttons: EnabledButtons

Specifies which window control buttons should be enabled.

Platform-specific

iOS, Android, and the Web do not have window control buttons.

On some Linux environments these values have no effect.

decorations: bool

Should the window have decorations enabled?

(Decorations are the minimize, maximize, and close buttons on desktop apps)

Platform-specific

iOS, Android, and the Web do not have decorations.

transparent: bool

Should the window be transparent?

Defines whether the background of the window should be transparent.

Platform-specific

• iOS / Android / Web: Unsupported.
• macOS: Not working as expected.

macOS transparent works with winit out of the box, so this issue might be related to: https://github.com/gfx-rs/wgpu/issues/687. You should also set the window composite_alpha_mode to CompositeAlphaMode::PostMultiplied.

focused: bool

Get/set whether the window is focused.

window_level: WindowLevel

Where should the window appear relative to other overlapping window.

Platform-specific

• iOS / Android / Web / Wayland: Unsupported.

canvas: Option<String>

The “html canvas” element selector.

If set, this selector will be used to find a matching html canvas element, rather than creating a new one. Uses the CSS selector format.

This value has no effect on non-web platforms.

prevent_default_event_handling: bool

Whether or not to stop events from propagating out of the canvas element

When true, this will prevent common browser hotkeys like F5, F12, Ctrl+R, tab, etc. from performing their default behavior while the bevy app has focus.

This value has no effect on non-web platforms.

internal: InternalWindowState

Stores internal state that isn’t directly accessible.

ime_enabled: bool

Should the window use Input Method Editor?

If enabled, the window will receive Ime events instead of ReceivedCharacter or KeyboardInput.

IME should be enabled during text input, but not when you expect to get the exact key pressed.

Platform-specific

• iOS / Android / Web: Unsupported.

ime_position: Vec2

Sets location of IME candidate box in client area coordinates relative to the top left.

Platform-specific

• iOS / Android / Web: Unsupported.

window_theme: Option<WindowTheme>

Sets a specific theme for the window.

If None is provided, the window will use the system theme.

Platform-specific

• iOS / Android / Web: Unsupported.

visible: bool

Sets the window’s visibility.

If false, this will hide the window the window completely, it won’t appear on the screen or in the task bar. If true, this will show the window. Note that this doesn’t change its focused or minimized state.

Platform-specific

• Android / Wayland / Web: Unsupported.

Implementations
