- CStLayerOriginSetter
-
- This class is used to set the layer origin temporarily. For example, if you are dragging and
- dropping and want the origin to be changed to the item you're dragging, you would do (in
- CHTMLView):
-
-
- do stuff with old origin
- {
- CStOriginSetter setLayerOrigin(this, in_layer);
- do your dragging stuff with new origin
- }
- do other stuff with old origin
-
- This class thus handles any exceptions, etc. that are done while doing stuff with the new
- origin.
-
- NOTE: This class should never be subclassed.
