Qwt 6.1-rc1 is out too and all I have done so far is buying a book about DocBook.
Concerning the examples: what topics would you like to see that are not covered by the existing ( 6.1 ) examples already ?

Reviewing v6.1 examples now.
In general generic examples that do nothing are not useful in practice for newbies to Qwt. On topic, an example of using Qwt to make a waterfall widget that displays sound captured (from say a jack audio input client) would be an outstandingly practical example for anyone as long as it works.
I completely disagree, examples like simpleplot are exactly what a newbie needs. The complete example has 42 lines of code and shows how easy it is to set up an application with a curve chart. This is the relevant information a user needs to know to get a project started.In general generic examples that do nothing are not useful in practice for newbies to Qwt.
Nothing could be more off topic than this. A waterfall plot qualifies as a demo like the oscilloscope - a cool application showing the power of Qwt, but leaving a newbie completely clueless, when reading the code.On topic, an example of using Qwt to make a waterfall widget that displays sound captured (from say a jack audio input client) would be an outstandingly practical example for anyone as long as it works.
But don't get me wrong: I would like to have a demo for a waterfall plot too, but the problem is the generation of the data:
- examples have to run on all target platforms without external dependencies - nobody installs and runs jack only to see how Qwt works.
- you can't blow up the size of a Qwt tarball with recorded data ( like the cpuplot example does for systems without a proc file system )
That's why in the end examples often end with synthetic data.
So if you have a specification for a waterfall plot and an idea how to generate the data I would be willing to implement such a demo. Also I could imagine to offer a more high level set of widgets - if I would have reasonable specifications - like:
- QwtOscilloscope
- QwtWaterfallPlot
- ...
This is not the first thread about a waterfall example, but unfortunately ideas like this usually die as soon as I'm asking for any type of contribution ...
