Add the following function before the OnOpen function definition: |
L_VOID OnShapeDlg ( HWND hWnd, pPAINTHANDLE pPaint ){PAINTSHAPE shape ;PAINTDLGSHAPEINFO ShapeDlgInfo ;L_INT nRet ;RECT rcRect;HDC hdcTest;hdcTest = GetDC (hWnd);L_PntGetProperty ( pPaint, PAINT_GROUP_SHAPE, &shape ) ;ShapeDlgInfo.dwFlags = PAINT_DLG_SHAPE_SHOWALL ;ShapeDlgInfo.pszTitle = TEXT("Shape Properties");ShapeDlgInfo.nBackgroundStyle = shape.nBackgroundStyle ;ShapeDlgInfo.crBackgroundColor = shape.crBackgroundColor ;ShapeDlgInfo.ppszBackgroundTileBitmap = NULL ;ShapeDlgInfo.uBackgroundTileBitmapCount = 0 ;ShapeDlgInfo.nActiveBackgroundTileBitmapItem = -1 ;ShapeDlgInfo.nBorderStyle = shape.nBorderStyle ;ShapeDlgInfo.nBorderBrushStyle = shape.nBorderBrushStyle ;ShapeDlgInfo.crBorderColor = shape.crBorderColor ;ShapeDlgInfo.ppszBorderTileBitmap = NULL ;ShapeDlgInfo.uBorderTileBitmapCount = 0 ;ShapeDlgInfo.nActiveBorderTileBitmapItem = -1 ;ShapeDlgInfo.nBorderWidth = shape.nBorderWidth ;ShapeDlgInfo.nBorderEndCap = shape.nBorderEndCap ;ShapeDlgInfo.nGradientStyle = shape.nGradientStyle ;ShapeDlgInfo.crGradientStartColor = shape.crGradientStartColor ;ShapeDlgInfo.crGradientEndColor = shape.crGradientEndColor ;ShapeDlgInfo.uGradientSteps = shape.uGradientSteps ;ShapeDlgInfo.nRoundRectEllipseWidth = shape.nRoundRectEllipseWidth ;ShapeDlgInfo.nRoundRectEllipseHeight = shape.nRoundRectEllipseHeight ;ShapeDlgInfo.nOpacity = shape.nOpacity ;ShapeDlgInfo.ppszPaperTexture = NULL ;ShapeDlgInfo.uPaperTextureCount = 0 ;ShapeDlgInfo.nActivePaperTextureItem = -1 ;nRet = L_PntDlgShape ( hWnd, &ShapeDlgInfo ) ;if ( SUCCESS == nRet ){shape.nSize = sizeof ( PAINTSHAPE ) ;shape.dwMask = PSF_ALL ;shape.nBackgroundStyle = ShapeDlgInfo.nBackgroundStyle ;shape.crBackgroundColor = ShapeDlgInfo.crBackgroundColor ;shape.pBackgroundTileBitmap = NULL ;shape.nBorderStyle = ShapeDlgInfo.nBorderStyle ;shape.nBorderBrushStyle = ShapeDlgInfo.nBorderBrushStyle ;shape.crBorderColor = ShapeDlgInfo.crBorderColor ;shape.hBorderTileBitmap = NULL ;shape.nBorderWidth = ShapeDlgInfo.nBorderWidth ;shape.nBorderEndCap = ShapeDlgInfo.nBorderEndCap ;shape.nGradientStyle = ShapeDlgInfo.nGradientStyle ;shape.crGradientStartColor = ShapeDlgInfo.crGradientStartColor ;shape.crGradientEndColor = ShapeDlgInfo.crGradientEndColor ;shape.uGradientSteps = ShapeDlgInfo.uGradientSteps ;shape.nRoundRectEllipseWidth = ShapeDlgInfo.nRoundRectEllipseWidth ;shape.nRoundRectEllipseHeight = ShapeDlgInfo.nRoundRectEllipseHeight ;shape.nOpacity = ShapeDlgInfo.nOpacity ;shape.pTexture = NULL ;L_PntSetProperty ( pPaint, PAINT_GROUP_SHAPE, &shape ) ;// now draw something to see the results of the dialog settingsSetRect(&rcRect, 10, 10, 100, 100);L_PntDrawShapeRectangle(pPaint, hdcTest, &rcRect);}}
