LVectorDialog::DoModalVectorEditLayer

#include "ltwrappr.h"

virtual L_INT LVectorDialog::DoModalVectorEditLayer(hWndParent, pVectorLayer, pbActiveLayer=NULL)

Brings up the Vector Edit Layer dialog. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameters

HWND hWndParent

Handle of the window that owns the dialog.

LVectorLayer * pVectorLayer

Pointer to an LVectorLayer object that references the layer to be edited.

L_BOOL * pbActiveLayer

Pointer to an L_BOOL variable that indicates whether or not to use the active layer. 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, a value obtained from the pVectorLayer and parameter and the LVectorBase object associated with the dialog will be used to initialize the dialog. When this function returns, if this parameter is not NULL, the variable will be updated with the value entered through the dialog.
