Which one is required for the start and end in QwtScaleWidget::setBorderDist (int start, int end)?

What is the motivation behind trying to modify the border distances ?

Uwe,
I am learning to use qwt to code something recently. Yesterday when I read some thread in our forum (the picture is cut from that thread)I found this.I am curious about the distance mentioned before.How does it come out? I dived into the codes about QwtPlot, QwtPlotLayout, etc.But I have no idea.And why not extend the backbone to touch the canvas edge?If I want to do that, how?

See: http://qwt.sourceforge.net/class_qwt...b500dc35096d67
F.e. see the spectrogram example.
