Description |
|
uStructSize |
Size of this structure. Use sizeof(ANNHITTESTINFO). |
|
nHandleIndex |
This is the zero-based index of the handle. This field is valid only if puResult of LAnnContainer::HitTest is updated with either ANNHIT_HANDLE or ANNHIT_USER_HANDLE. The default handles and the user handles are maintained internally as separate arrays of handles. This means that there is both a default handle "0" and a user handle "0". This index can be used with other annotation handle functions. |
|
nHandleID |
The unique ID associated with the user handle. The ID can be set with the LAnnXXX::AddUserHandle, LAnnXXX::ChangeUserHandle, or LAnnXXX::EnumerateHandles functions, where LAnnXXX represents the classes that support handles. These classes are as follows: |
