    Default QwtLegend orientation on QwtPlot

    I've created a multi-curve QwtPlot with a legend as a child of the canvas at the top, but the legend items are all strung out on a single line across the top of the plot.

    // add a legend
    QwtLegend* legend = new QwtLegend();
    legend->setParent( canvas() );
    insertLegend( legend, QwtPlot::ExternalLegend );

    I'd like to see each item on its own line; i.e. arranged vertically down the left side of the plot.
    Can this be done?

    Qt Code:
    1. QwtDynGridLayout *layout = qobject_cast<QwtDynGridLayout *>( legend->contentsWidget()->layout() );
    2. if ( layout )
    3. layout->setMaxCols( 1 );
    To copy to clipboard, switch view to plain text mode 

  3. The following user says thank you to Uwe for this useful post:
