EC_FULLSCREEN_LOST

  • 项目

The video renderer is switching out of full-screen mode.

Parameters

  • lParam1
    Zero.
  • lParam2
    Pointer to the IBaseFilter interface that is sending the notification (the Mode X renderer in this case).

Remarks

The full-screen renderer sends this event notification to an application. When the EC_ACTIVATE notification is sent to the filter graph manager upon switching out of full-screen mode, the filter graph manager sends an EC_FULLSCREEN_LOST notification to the controlling application. The application might use this notification to restore the state of a full-screen button, for example. The EC_ACTIVATE notifications are used internally by DirectShow to manage full-screen switching on cues from the video renderers.

For information on how to use this event code, see CBaseFilter::NotifyEvent.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
