virtual L_INT LAnnHotSpot::EnumHandleCallBack(hObject, pHandleInfo)

Processes each annotation object from the LAnnHotSpot::EnumerateHandles function. This function is available in the Document/Medical Toolkits.

Returns

Comments

The LAnnHotSpot::EnumerateHandles function calls your callback function for each handle of a single annotation object.

The pHandleInfo structure can be used to obtain detailed information about an annotation object handle. It can also be used to change some (but not all) of the properties of a user handle. All properties of an annotation object handle can be changed EXCEPT the location. The properties of a node that can be changed with this function are:

• ID

• Visibility

• Pen color

• Fill color

• Shape

• Cursor

To change the location of a user-defined node, use LAnnHotSpot::ChangeUserHandle.

To change the properties of an annotation object handle, set the corresponding field in the pHandleInfo structure, and return SUCCESS_CHANGED. To leave the handle properties unchanged, return SUCCESS_UNCHANGED.

To enable the LAnnHotSpot::EnumHandleCallBack you must call LBase::EnableCallBack before calling LAnnHotSpot::EnumerateHandles function.

For more information, refer to the documentation for ANNHANDLEINFO.
