Accessing TPen

You can access TPen through an HPEN or as a LOGPEN structure.

To get an HPEN from a TPen object, use the HPEN() operator with the TPen object as the parameter. The HPEN() operator is almost never explicitly invoked.

HPEN GetHPen(TPen& pen)
{
 return pen;
}

This code automatically invokes the HPEN() conversion operator to cast the TPen object to the correct type.

To convert a TPen object to a LOGPEN structure, use the TPen::GetObject function:

bool GetLogPen(LOGPEN far& logPen)
{
 TPen pen(TColor::LtMagenta, 10);
 return pen.GetObject(logPen);
}

The following example shows how to use a pen with a TDC to draw a line: void

TPenDemo::DrawLine(TDC& dc, const TPoint& point, TColor& color)
{
 TPen BrushPen(color, PenSize);
 dc.SelectObject(BrushPen);
 dc.LineTo(point);
}
