This section lists the filter graph notifications that a renderer can send.
| Event notification | Description |
|---|---|
| EC_ACTIVATE | Sent by video renderers in full-screen rendering mode for each WM_ACTIVATEAPP message received. |
| EC_COMPLETE | Sent by renderers after all data has been rendered. |
| EC_DISPLAY_CHANGED | Sent by video renderers when a display format changes. |
| EC_PALETTE_CHANGED | Sent whenever a video renderer detects a palette change in the stream. |
| EC_REPAINT | Sent by stopped or paused video renderers when a WM_PAINT message is received and there is no data to display. This causes the filter graph manager to generate a frame to paint to the display. |
| EC_USERABORT | Sent by video renderers to signal a closure that the user requested (for example, a user closing the video window). |
| EC_VIDEO_SIZE_CHANGED | Sent by video renderers whenever a change in native video size is detected. |
| EC_WINDOW_DESTROYED | Sent by video renderers when the filter is removed or destroyed so that resources that depend on window focus can be passed to other filters. |
