Description

uStructSize

Size of this structure. Use sizeof(ANNHANDLEINFO)

nType

Type of handle. Possible values are:

Value

Meaning

ANNHANDLETYPE_DEFAULT_HANDLE

A default annotation handle.

ANNHANDLETYPE_USER_HANDLE

A user-defined annotation handle.

ANNHANDLETYPE_ROTATE_HANDLE

A rotate annotation handle.

nID

Unique identifier of the annotation handle. If nType is ANNHANDLETYPE_ROTATE_HANDLE, then nID specifies if this is a center rotate handle (ROTATE_HANDLE_CENTER_ID) or a gripper rotate handle (ROTATE_HANDLE_GRIPPER_ID).

nIndex

This is the index of the user handle of the privately maintained array of user handles. Use nIndex with ChangeUserHandle or DeleteUserHandle functions of the LAnnAudioClip, LAnnButton, LAnnCrossProduct, LAnnCurve, LAnnCurveClosed, LAnnEllipse, LAnnEncrypt, LAnnFreehand, LAnnFreehandHotSpot, LAnnHilite, LAnnHotSpot, LAnnLine, LAnnNote, LAnnPolygon, LAnnPoint, LAnnPolyline, LAnnPolyRuler, LAnnProtractor, LAnnPointer, LAnnPushPin, LAnnRedact, LAnnRectangle, LAnnRTF, LAnnRuler, LAnnStamp, LAnnText, LAnnTextPointer, LAnnToolBar, LAnnVideo classes. This is only valid if the type of the handle is ANNHANDLETYPE_DEFAULT_HANDLE.

ptLocationContainer

The location of the handle in container coordinates. Container coordinates are typically the same dimensions of the underlying bitmap, and are independent of zooming and scrolling.

ptLocationClient

The location of the handle in client coordinates. Client coordinates factor in the current zoom factor, and the horizontal and vertical scrolling.

bVisible

Value that indicates whether the handle is visible. Possible values are:

Value

Meaning

TRUE

The handle is visible.

FALSE

The handle is invisible.

crPen

A COLORREF value that represents the color of the pen used to draw the user handle (the outline of the handle).

crFill

A COLORREF value that represents the color used to fill the user handle.

nShape

A value that indicates the shape of the handle. Possible values are:

Value

Meaning

ANNHANDLE_SHAPE_SQUARE

The shape of the user handle is square

ANNHANDLE_SHAPE_CIRCLE

The shape of the user handle is a circle

hCursor

Handle to a cursor. This is the cursor that appears when the mouse hovers over the user handle. If this value is zero, then a default cursor will appear.

nTotalHandles

The total number of annotation object handles. This includes both the default annotation handles and the user-defined annotation handles.

nReserved

Reserved for future use. Must set this field to zero.
