PlotPicker: TrackerText Position

[Uwe]

Overloading drawTracker is the correct idea. Start with this code:

void YourPicker::drawTracker( QPainter *painter ) const
{
    const QRect textRect = trackerRect( painter->font() );
    if ( !textRect.isEmpty() )
    {
        QwtText label = trackerText( trackerPosition() );
        if ( !label.isEmpty() )
            label.draw( painter, textRect );
    }
}

void YourPicker::drawTracker( QPainter *painter ) const
{
    const QRect textRect = trackerRect( painter->font() );
    if ( !textRect.isEmpty() )
    {
        QwtText label = trackerText( trackerPosition() );
        if ( !label.isEmpty() )
            label.draw( painter, textRect );
    }
}

To copy to clipboard, switch view to plain text mode
