macOS Finder column view modify width of active column

[foxs]

Is there a way in any language written for OSX (Applescript, C++, etc.) where I can access the function (adjust column width) in the context menu, when you right click on the two lines at the bottom of the Scrollbar in Finders Column View (AXMenu->AXMenuItem)? Same happens if you double click on the two lines.

Because, what I want to do is somehow get a shortcut on this function for »super-fast- finder-workflows«

thanks

Is there no answer or does no one know?

I explored this extensively a couple years back, but unfortunately there was no way to do it programmatically. I tried to do it by simulating mouse events, and it works OK, but not 100%...

How do you detect where to double click with the mouse?
Because basically it should expand the column where im currently
active in. That would probably be the optimal case.


Thanks

trying to push again. It has to be possible somehow!

If you can find a way to access the NSApplication, NSApplicationDelegate, or NSWindow, this is trivial. I feel like there's probably a fairly easy, hack for scanning through memory and finding the address. Then you just use introspection through the subviews until you find the column view and modify the relevant properties.

Alternatively, if Finder allows plugins, it may already let you know about the NSWindow.

It looks like Finder doesn't allow plugins, but other people have explored the methods that I was describing:

Some of those answers look pretty good to me.
