LVectorDialog::DoModalVectorCamera

#include "ltwrappr.h"

virtual L_INT LVectorDialog::DoModalVectorCamera(hWndParent=NULL, pCamera=NULL))

HWND hWndParent;	/* handle of the window that owns the dialog */
pVECTORCAMERA pCamera;	/* pointer to a VECTORCAMERA structure */

Brings up the Vector Camera dialog.

Parameter	Description
hWnd	Handle of the window that owns the dialog.
pCamera	Pointer to a VECTORCAMERA structure that contains camera values. The values present in pCamera 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.

Returns

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

Comments

Object selection has no effect on the camera.
