Options controlling the behavior of a native window.

Only a single native window is currently supported.

Fields

always_on_top: bool

Sets whether or not the window will always be on top of other windows.

maximized: bool

Show window in maximized mode

decorated: bool

On desktop: add window decorations (i.e. a frame around your app)? If false it will be difficult to move and resize the app.

drag_and_drop_support: bool

On Windows: enable drag and drop support. Default is false to avoid issues with crates such as cpal which will hang when combined with drag-and-drop. See https://github.com/rust-windowing/winit/issues/1255.

icon_data: Option<IconData>

The application icon, e.g. in the Windows task bar etc.

initial_window_pos: Option<Pos2>

The initial (inner) position of the native window in points (logical pixels).

initial_window_size: Option<Vec2>

The initial inner size of the native window in points (logical pixels).

min_window_size: Option<Vec2>

The minimum inner window size

max_window_size: Option<Vec2>

The maximum inner window size

resizable: bool

Should the app window be resizable?

transparent: bool

On desktop: make the window transparent. You control the transparency with App::clear_color(). You should avoid having a egui::CentralPanel, or make sure its frame is also transparent.
