Additional methods on WindowAttributes that are specific to Windows.

Required Methods§

source

fn with_owner_window(self, parent: HWND) -> Self

Set an owner to the window to be created. Can be used to create a dialog box, for example. This only works when WindowAttributes::with_parent_window isn’t called or set to None. Can be used in combination with WindowExtWindows::set_enable(false) on the owner window to create a modal dialog box.

From MSDN:

An owned window is always above its owner in the z-order.
The system automatically destroys an owned window when its owner is destroyed.
An owned window is hidden when its owner is minimized.

For more information, see https://docs.microsoft.com/en-us/windows/win32/winmsg/window-features#owned-windows

source

fn with_menu(self, menu: HMENU) -> Self

Sets a menu on the window to be created.

Parent and menu are mutually exclusive; a child window cannot have a menu!

The menu must have been manually created beforehand with [CreateMenu] or similar.

Note: Dark mode cannot be supported for win32 menus, it’s simply not possible to change how the menus look. If you use this, it is recommended that you combine it with with_theme(Some(Theme::Light)) to avoid a jarring effect. [CreateMenu]: #only-available-on-windows

source

fn with_taskbar_icon(self, taskbar_icon: Option<Icon>) -> Self

This sets ICON_BIG. A good ceiling here is 256x256.

source

fn with_no_redirection_bitmap(self, flag: bool) -> Self

This sets WS_EX_NOREDIRECTIONBITMAP.

source

fn with_drag_and_drop(self, flag: bool) -> Self

Enables or disables drag and drop support (enabled by default). Will interfere with other crates that use multi-threaded COM API (CoInitializeEx with COINIT_MULTITHREADED instead of COINIT_APARTMENTTHREADED) on the same thread. Note that winit may still attempt to initialize COM API regardless of this option. Currently only fullscreen mode does that, but there may be more in the future. If you need COM API with COINIT_MULTITHREADED you must initialize it before calling any winit functions. See https://docs.microsoft.com/en-us/windows/win32/api/objbase/nf-objbase-coinitialize#remarks for more information.
