View Full Version : pixel distance of gaps in scaleWidget

1st November 2008, 10:17
Hi every one.

My project - is multiplot widget. I choose to place them in QScrollview and separate yLeft sclale of plots to another QScrollview, which is placed left form main scrollview (it is done to cover cases then we move horizontal scrollbar and left scales will not be visible).

Right now I'm setting scaldivs and scaledraws of scalewidget from plot's scales. Sizes of separate scaleWidgets and corresponding plot's leftscale are match. But I don't know sizes of blank spaces between which are above leftscale and below. On picture below this gaps are inside of black sqares.

I don't is it a good and simple method to work with many plots. May be expert users of Qwt can suggest me better method.

Very big thanks for your answers!

The methods you are looking for might be QwtScaleWidget::startBoderDist/endBorderDist or QwtScaleDraw::getBorderDistHint().

In the end Qwt is not very comfortable for aligning plot widgets, but it could help to have a look at the plotmatrix example from SVN trunk ( = 5.2 ).
