7.6.3 Hatched Brushes..................................................................................

A hatch brush is one that uses a drawn pattern to regularly fill an area. Microsoft

Windows provides 6 preset patterns for such a brush. To create a hatched brush, you can

use the following constructor:

CBrush(int nIndex, COLORREF crColor);

If you had declared a CBrush variable using the default constructor, you can call the

CreateHatchBrush() member function to initialize it. The syntax of this method is:

BOOL CreateHatchBrush(int nIndex, COLORREF crColor);

In both cases, the nIndex argument specifies the hatch pattern that must be used to fill the

area. The possible values to use are HS_BDIAGONAL, HS_CROSS, HS_DIAGCROSS,

HS_FDIAGONAL, HS_HORIZONTAL, or HS_VERTICAL.

The crColor argument specifies the color applied on the drawn pattern.

Here is an example:

void CExoView::OnDraw(CDC* pDC)

{

CExoDoc* pDoc = GetDocument();

ASSERT_VALID(pDoc);

CBrush brBDiagonal(HS_BDIAGONAL, RGB(0, 0, 255));

CBrush brCross;

CBrush brDiagCross(HS_DIAGCROSS, RGB(0, 128, 0));

CBrush brFDiagonal;

CBrush brHorizontal(HS_HORIZONTAL, RGB(255, 128, 0));

CBrush brVertical;

CBrush *pBrush;
