示例1: drawCanvas
//! Redraw grid, curves, and markers. The draw code
// does not clear clipRegion prior to painting.
// \param p painter used for drawing
void QwtPlot::drawCanvas(QPainter *p)
{
QwtDiMap map[axisCnt];
for ( int axis = 0; axis < axisCnt; axis++ )
map[axis] = canvasMap(axis);
QRect rect = d_canvas->contentsRect();
//
// draw grid
//
if ( d_grid.enabled() &&
axisEnabled( d_grid.xAxis() ) &&
axisEnabled( d_grid.yAxis() ) )
{

//
// draw curves
//
QIntDictIterator<QwtPlotCurve> itc(*d_curves);
