How can I figure out which framework was used for build desktop application's (Zoom) UI?

Question

I would like to know which framework was used to build Zoom(windows & mac)'s UI.

Is that possible somehow? Would decompiling help?

Zoom's desktop application

Answer 1

You can download Zoom's Linux client and choose Other Linux OS from the drop down menu. Then run the following command in a Linux terminal:

$ tar -xf zoom_x86_64.tar.xz

The execution of the command results in a directory called zoom being created and when you list it's contents using this command:

$ ls zoom

You get the following output:

As you can see, a lot of the filenames start with libQt5 or Qt, so I would assume, that the framework used to develop the Linux desktop client is the Qt Framework. And because the Linux client and the Windows client share the same user interface, they are probably both using Qt.
