IInkCollector::get_AutoRedraw method (msinkaut.h)
Gets or sets a value that specifies whether an ink collector repaints the ink when the window is invalidated.
This property is read/write.
Syntax
HRESULT get_AutoRedraw(
VARIANT_BOOL *AutoRedraw
);
Parameters
AutoRedraw
Return value
None
Remarks
If VARIANT_TRUE, the ink collector repaints the ink when the window is invalidated. For example, if you minimize the window and then restore it, the ink is automatically redrawn. If VARIANT_FALSE, the ink collector does not repaint the ink when the window is invalidated. For example, if you minimize the window and then restore it, the ink disappears from the screen.
When AutoRedraw is VARIANT_FALSE, the ink appears while inking unless the DynamicRendering property is false.
When your application is performing custom rendering or when your application is sensitive to painting issues, you can handle the repainting yourself and set the AutoRedraw property to VARIANT_FALSE for the InkCollector object, the InkOverlay object, or the InkPicture control. Use the events in the following table to handle the repainting.
| Object or Control | Event |
|---|---|
| InkCollector Object | The underlying controls Invalidated and Paint events. |
| InkOverlay Object | The underlying controls Invalidated and Paint events. |
| InkPicture Control | InkPicture controls inherited Invalidated and Paint events. |
