|---|---|
VOID ACCUAPI ARTModifyNotify( HIGEAR hIGear, LPVOID lpPrivate, ART_MARK_INDEX hMarkIndex, const LPART_MARK_ATTRIBUTES lpMarkAttr, AT_MODE nReason) { switch (nReason) { case ART_MODIFY_ATTRIBUTES: /* indicate to the user that the highlight */ /* attribute was changed */ if (lpMarkAttr->bHighlighting) MessageBox(HWND_DESKTOP, "The mark is " "highlighted", NULL, MB_OK); } } |
|
Remarks:
 |
In order to use this callback, it must be registered with ART using the function ART_callback_register(). |
Upon entry, nReason is set to a constant indicating what triggered the modification. Your application displays one of the library's standard editing dialog boxes. Here is the list of "reasons" why this callback will be called:
| ART_MODIFY_ATTRIBUTES | One or more attributes have been modified (from the ART_MARK_ATTRIBUTES structure). |
| ART_MODIFY_ANODAT | A named block specific to this type of mark was modified. |
| ART_MODIFY_FILNAM | The filename block was modified. |
| ART_MODIFY_DIB | The embedded DIB was changed. |
| ART_MODIFY_GROUP | The mark's group block was modified. |
| ART_MODIFY_INDEX | The mark's index block was changed. |
| ART_MODIFY_ANTEXT | The orientation or length of text mark have been modified. |
| ART_MODIFY_NAMED_BLOCK | A user-defined named block was modified. |
