Example

This example shows the minimum requirements for painting a rectangle shape.

 L_INT PntInitExample(HWND hWnd)
{
   L_INT nRet;
   pPAINTHANDLE pPaint ;
   HDC          hDC ;
   RECT         rcShapeRect ;

   /* Initiate the Paint toolkit */
   nRet  = L_PntInit ( &pPaint );
   if ( SUCCESS != nRet)
   {
      return nRet ;
   }

   /*Get the device context*/
   hDC = GetDC ( hWnd ) ;

   /* Set the rectangle coordinates with respect to the DC dimensions*/
   SetRect ( &rcShapeRect, 10, 10, 100, 100 ) ;

   /* Use the default properties for the shape to draw a rectangle*/
   nRet = L_PntDrawShapeRectangle ( pPaint, hDC, &rcShapeRect ) ; 
   if(nRet != SUCCESS)
      return nRet;

   /* Release the device context*/
   ReleaseDC ( hWnd, hDC ) ;

   // Free the paint tools handle.
   L_PntFree ( pPaint ) ;
