Hi All,

I wish to replicate the zoomer functionality of the qwtplot in my own application but I do not wish to use the entire qwt library due to some performance related issues.

What I have tried to do :

I have taken some of the examples provided with the qwt package containing the zoomer functionality in debug and tried to observe what all is happening after the zoomer object is being created. Somehow I am getting lost somewhere in the middle and have to restart again.

What I want to achieve

I want to reuse only that part of the code (only the classes and methods from qwt library) that are required for the zoomer functionality. Is my approach the only way to do that? Or is there any other faster more efficient way how I can achieve that.
