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.
