In addition to the -functions provided by <a href="qmemarray.html">TQMemArray</a>, TQPointArray provides some -point-specific functions. -<p> For convenient reading and writing of the point data use -setPoints(), <a href="#putPoints">putPoints</a>(), <a href="#point">point</a>(), and <a href="#setPoint">setPoint</a>(). -<p> For geometry operations use <a href="#boundingRect">boundingRect</a>() and <a href="#translate">translate</a>(). There -is also the <a href="qwmatrix.html#map">TQWMatrix::map</a>() function for more general -transformations of TQPointArrays. You can also create arcs and -ellipses with <a href="#makeArc">makeArc</a>() and <a href="#makeEllipse">makeEllipse</a>(). -<p> Among others, TQPointArray is used by <a href="qpainter.html#drawLineSegments">TQPainter::drawLineSegments</a>(), -<a href="qpainter.html#drawPolyline">TQPainter::drawPolyline</a>(), <a href="qpainter.html#drawPolygon">TQPainter::drawPolygon</a>() and -<a href="qpainter.html#drawCubicBezier">TQPainter::drawCubicBezier</a>(). -<p> Note that because this class is a TQMemArray, copying an array and -modifying the copy modifies the original as well, i.e. a <a href="shclass.html#shallow-copy">shallow copy</a>.
