LVectorDialog::DoModalVectorRotate

#include "ltwrappr.h"

virtual L_INT LVectorDialog::DlgRotate(hWndParent=NULL, pRotation=NULL, pOrigin=NULL)

HWND hWndParent;	/* window handle */
pVECTORPOINT pRotation;	/* pointer to a VECTORPOINT structure */
const pVECTORPOINT pOrigin;	/* pointer to a VECTORPOINT structure */

Brings up the Vector Rotation dialog.

Parameter	Description
hWndParent	Handle of the window that owns the dialog.
pRotation	Pointer to a VECTORPOINT structure that contains rotation values. The values present in pRotation when the function is called are used to initialize the dialog. If this parameter is NULL when the function is called, the values used to initialize the dialog will come from the vector handle. When this function returns, this parameter is updated with the values entered through the dialog.
pOrigin	Pointer to a VECTORPOINT structure that contains the origin of the rotation. (The point about which the rotation occurs.) If pOrigin is not NULL, rotation occurs around this point. If pOrigin is NULL, the center of rotation is the accumulative center of the objects to be rotated.

Returns

SUCCESS	The function was successful.
ERROR_DLG_CANCELED	User clicked the Cancel button.

Comments

If no objects are currently selected in the source vector handle, all of the objects in the vector handle will be rotated in the dialog.

If there are selected objects inside the source vector handle, only those objects will be rotated in the dialog.
