QwtSamplingThread usage

[Momergil]

Hello!

I would like to know more about the clas QwtSamplingThread: how do I implement it and if there is an example of it being used. Unfortunately the Detailed Description in Qwt's help file don't say too much.


Thanks,

There is not much to say, beside that it starts a thread calling sample() periodically. The oscilloscope example uses it.

Ok, I'll give a look at the example; should be enough.

Just a small note:

I tried to implement a class with QwtSamplingThread and the periodic sample() wasn't working. I was almost coming here for help when I noticed that in the osciloscope example the run() function was not declared, just sample(), so I did the same and it began to work. So I'l recommend to add this note in the Qwt help files: not to implement run() in order for sample() to work!


Thanks,
