I think you underestimate the power of language barriers.
What exactly is the problem with creating a CPU widget?
What Qt concerns it could be as simple as using a QLabel to display a
percentage of the available cpu, as read out from some system function,
though probably you want to make a graphical view which is a bit more
complex.
I suggest you read up on custom drawn widgets using paintEvent.

Hello Navid,
Since Qt doesn't provide any API to read the CPU usage you would have to
get the data by using native APIs.
Once you have the data in a suitable format, use a widget like
QProgressBar (if you want to display percentage of total CPU load), or a
QTableView (if you want to display the data in a tabular format), or your
own custom widget that displays a graph.

Navid,
If you need a graph widget, take a look at qwt. (Open Source) you can find
them at http://qwt.sourceforge.net It is Qt3 and QT4 compatible and very well
documented.
Kind regards,

Dear Navid Parvini,
best is to use a standard QT widget. e.g. label with % or
a progress bar. If you need a graph you have to draw one.
That is the easy part. More difficult is to find out
what the CPU usage is. That is very OS dependent and you
will find that QT has no solution for you.
I also think we have a 'cultural gap' here.
The way you pose your question is VERY likely to be
interpreted as: "Please design for me a widget which does....."
in the same way as walking up to somebody and say "please give me some money".
I suggest you look at how other people, who do get lots of answers, ask their questions.

Dear All,
I want to get the CPU usage in my code.
Is there any Class in Qt to get it?
I want to get in both Windows and Linux.
Thank you in advance.

As I said before:
"Since Qt doesn't provide any API to read the CPU usage you would have to
get the data by using native APIs."

You had already asked this question on May 8th. There were many answers. What
do you need that you didn't find in the answers?
