LVectorDialog::DoModalVectorRender

#include "ltwrappr.h"

virtual L_INT LVectorDialog::DoModalVectorRender(hWndParent=NULL, pnPolygonMode=NULL)

HWND hWndParent;	/* window handle */
L_INT *pnPolygonMode;	/* polygon draw mode */

Brings up the Vector Render Options dialog.

Parameter	Description
hWndParent	Handle of the window that owns the dialog.
pnPolygonMode	Pointer to an L_INT variable that contains a polygon mode value. The value present in the variable when the function is called is used to initialize the dialog. If this parameter is NULL when the function is called, the value used to initialize the dialog will come from the vector handle. When this function returns, if this parameter is not NULL, the variable pointed to by pnPolygonMode is updated with the value entered through the dialog.

Returns

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

Comments

This function lets you change the polygon draw mode. Updating the variables is not affected by whether or not an object is selected.

If the GDI engine is being used, the bUseLights and pColorAmbient variables are not used.
