Hi,

And again, if you are thinking of complete pre-made widgets like that ? No, Qt provides the building blocks for that.

For curve representation, you might be interest in the Qwt library

the controls points of the curve can be edited dynamically.
should i use QGraphicsView for this?
thank you

There are several options on how to do that. QGraphicsView / Scene could be an option, also looking at qwt. It all deends on the usage and the requirements.

yeh, i know qwt, is there any other demo except qwt?
thank you

[opengpu]

waiting

pushing the topic up will not help. If someone wants to answer or knows answer, he/she will do it.

Implementing custom widgets is a normal thing in Qt and described in the docs. Or you can also use google.
