示例1: resetAxes
void SequenceDialog::resetAxes(bool keep_lower)
{
if (!info_->sainfo()) return;
QCustomPlot *sp = ui->sequencePlot;
// Allow space for labels on the top and port numbers on the left.
double top_pos = min_top_, left_pos = min_left_;
if (keep_lower) {
top_pos = sp->yAxis->range().lower;
left_pos = sp->xAxis2->range().lower;
}
double range_span = sp->viewport().width() / sequence_w_;
sp->xAxis2->setRange(left_pos, range_span + left_pos);
range_span = sp->axisRect()->height() / (one_em_ * 1.5);
sp->yAxis->setRange(top_pos, range_span + top_pos);
double rmin = sp->xAxis2->range().size() / 2;
ui->horizontalScrollBar->setRange((rmin - 0.5) * 100, (info_->sainfo()->num_nodes - 0.5 - rmin) * 100);
xAxisChanged(sp->xAxis2->range());
ui->horizontalScrollBar->setValue(ui->horizontalScrollBar->minimum()); // Shouldn't be needed.
rmin = (sp->yAxis->range().size() / 2);
ui->verticalScrollBar->setRange((rmin - 1.0) * 100, (num_items_ - 0.5 - rmin) * 100);
yAxisChanged(sp->yAxis->range());
// It would be exceedingly handy if we could do one or both of the
// following:
// - Position an axis label above its axis inline with the tick labels.
// - Anchor a QCPItemText to one of the corners of a QCPAxis.
// Neither of those appear to be possible, so we first call replot in
// order to lay out our X axes, place our labels, the call replot again.
sp->replot(QCustomPlot::rpQueued);
QRect axis_rect = sp->axisRect()->rect();
key_text_->position->setCoords(axis_rect.left()

- sp->yAxis->tickLabelPadding()
- sp->yAxis->offset(),
