Methods

Close()

Closes and destroys the platform window. Called when the abstract window is disposed programmatically rather than through a user-initiated close gesture. The default implementation is a no-op for platforms that do not support imperative close.

public void Close()

GetService(Type)

Gets the service object of the specified type.

public object? GetService(Type serviceType)

Parameters

serviceType Type

An object that specifies the type of service object to get.

Returns

object

A service object of type serviceType.

-or-

null if there is no service object of type serviceType.

Invalidate()

Requests a redraw of the window surface. The platform should trigger a paint or render callback as soon as possible.

public virtual void Invalidate()

OnAnimationFrame(ref FrameEventRef) 

public void OnAnimationFrame(ref FrameEventRef @event)

Parameters

event FrameEventRef

OnMessage(HWND, WindowMessage, WPARAM, LPARAM) 

public int OnMessage(User32.Types.HWND hWnd, User32.WindowMessage uMsg, Types.WPARAM wParam, Types.LPARAM lParam)

Parameters

hWnd User32.Types.HWND
uMsg User32.WindowMessage
wParam Types.WPARAM
lParam Types.LPARAM

Returns

int

OnScrollWheel(ScrollWheelEventRef) 

protected virtual void OnScrollWheel(ScrollWheelEventRef scrollWheelEventRef)

Parameters

Render() 

public void Render()

Show()

Displays the window to the user. This may include making it visible, entering the main loop, or attaching it to the application's view hierarchy, depending on the platform.
