L_LTANN_API L_INT L_AnnSetAutoCursor(hAutomation, uItem, hCursor)

HANNOBJECT hAutomation;	/* handle to an automation object */
L_UINT uItem;	/* value that specifies the cursor to be displayed */
HCURSOR hCursor;	/* handle to a windows cursor */

Sets one of the cursors associated with automated annotations.

This function is available in the Document and Medical Imaging toolkits.

Parameter	Description
hAutomation	Handle to the annotation automation object.
uItem	Value that specifies the cursor to be displayed on various actions. Possible values are:
	Value	Meaning
	ANNAUTOCURSOR_DEFAULT	[0] Displayed when cursor is over the annotation container, and other action is occuring. The default is the windows predefined cursor IDC_ARROW.
	ANNAUTOCURSOR_DRAWNEW	[1] Displayed when drawing a new annotation (design mode). This is displayed on all tools except for ANNTOOL_SELECT.
	ANNAUTOCURSOR_HANDLE	[2] Displayed in design mode, when cursor is over an annotation handle.

		ANNOBJECT_FREEHANDHOTSPOT
		ANNOBJECT_AUDIO
		ANNOBJECT_VIDEO
		ANNOBJECT_PUSHPIN
	ANNAUTOCURSOR_MOVE	[4] Displayed in design mode, when an annotation is selected and the cursor is over the selected annotation (but not over the annotation handle).
	ANNAUTOCURSOR_SELECT	[5] Displayed in design mode, when hovering over an unselected annotation. The default is the windows predefined cursor IDC_IBEAM.
	ANNAUTOCURSOR_TEXT	[6] Displayed in design mode, when entering text into one of the following text annotations:
		ANNOBJECT_TEXT
		ANNOBJECT_TEXTPOINTER
		ANNOBJECT_RTF
		ANNOBJECT_NOTE
	The default is the windows predefined cursor IDC_IBEAM.
	ANNAUTOCURSOR_WAIT	[7] Displayed during the wait operation. The default is the hourglass.

	ANNAUTOCURSOR_ROTATE_CENTER	[9] Displayed when hovering over rotate center handle. The rotate handles are displayed only after calling L_AnnSetOptions (hAutomation, OPTIONS_NEW_ROTATE).
	The following cursors are displayed only after calling L_AnnSetOptions (hAutomation, OPTIONS_NEW_CURSORS).

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

If hAutomation is NULL, the annotation cursors are changed for all the automation objects that will be created from this point on. It also changes the cursors for the automation objects that have not had their cursors changed (still using defaults).

If hAutomation is not NULL, the hCursor is changed only for the specified automation object. Some programs create a new automation object each time a file is opened. This is especially true for MDI applications. In this case, the hCursor is set only for the current file. If you want this hCursor to be set for all files, you must set the hCursor each time you create a new automation object, or call L_AnnSetAutoCursor with hObject set to NULL.

Internally, a copy is made of hCursor, so the hCursor can be destroyed after calling this fuction.

To retrieve a copy of an annotation cursor, call L_AnnGetAutoCursor.
