Create a timeline GUI with possibility of zoom and mouse interaction

Mindful

Dear all, I would like to use PyQt5 to create a timeline just like the one in the figure below. I found it here: https://forum.qt.io/topic/113795/designing-a-custom-timeline-with-mouse-interaction. Is it possible? Unfortunately I am a noob, so I don't know where to start. Any suggestions are welcome

Hi,

You should start with the right part first.

What data are you going to work on ?

@SGaist I'm looking for a code that, with some modifications, could fit well with the project, for example this sequencer: https://github.com/scottwn/sequencer. Unfortunately if I had to start from scratch with the project I would not know how to do it

As suggested in my other thread, kdenlive can be a good source of inspiration.

@SGaist Yup! it seems great to me, thanks a lot for the tip! I saw that it was written in C ++. Do you know if there is something like this written exclusively in Python?

SGaist

I am not aware of such an application in Python (does not mean it does not exists).

Note that translating Qt code from C++ to Python is not the hardest thing to do.

Depending on your need and time, you might want to create Python bindings to reuse existing classes.

@SGaist Everything clear. These days I will try to do some tests with the codes. Thank you so much for the important tips, you have been very kind!
