LVectorDialog::DoModalVectorNewLayer

#include "ltwrappr.h"

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

Brings up the Vector New 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. If this parameter is not NULL, the object pointed to by pVectorLayer will be updated with the newly added layer structure. If this parameter is NULL, the dialog is initialized using default values. When the function returns, pVectorLayer will not be updated with the newly added layer, since pVectorLayer is NULL.

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 default value (TRUE) is 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.

Returns

Value Meaning

Example

This example will call the DoModalVectorNewLayer() dialog, and return the selected values.
It will not allow creation of duplicate layers.

L_INT LVectorDialog__DoModalVectorNewLayerExample(HWND hWnd, LVectorBase *pVector) 
{ 
   L_INT          nRet; 
   LVectorDialog  VectorDlg; 
 
   VectorDlg.SetVector (pVector); 
   VectorDlg.EnableAutoProcess (); 
 
   VectorDlg.EnableNoDuplicate (); 
 
   L_BOOL bActiveLayer = TRUE; 
   LVectorLayer VectorLayer; 
 
   nRet = VectorDlg.DoModalVectorNewLayer(hWnd, &VectorLayer, &bActiveLayer); 
   if (nRet == SUCCESS) 
   { 
      L_TCHAR szMsg[200]; 
      VECTORLAYERDESC Desc; 
      VectorLayer.GetLayerDesc (&Desc); 
      wsprintf(szMsg, TEXT("New Layer\nName[%s]\nVisible[%d]\nLocked[%d]"), 
               Desc.szName, 
               Desc.bVisible, 
               Desc.bLocked 
               ); 
      MessageBox(hWnd, szMsg, TEXT(""), MB_OK); 
   } 
   else 
      return nRet; 
 
   return SUCCESS; 
}
