Description Podagric 2022-02-01 13:32:08 UTC

STEPS TO REPRODUCE
Just open multiple tabs

OBSERVED RESULT
Kate's window gets so big that it can't be fully maximized, part of it is outside. 
In this screenshot you can see that the minimap is completely out of view: https://i.imgur.com/8GN4RDS.png

EXPECTED RESULT
Should the tabs move in a sort of carousel when the number is too high? That's what happens in other editors.


SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 5.23.90
KDE Frameworks Version: 5.90.0
Qt Version: 5.15.2
Graphics Platform: X11


ADDITIONAL INFORMATION
In addition to not being able to see part of the window, other interface elements are also compromised, such as the file browser. It is too small in size and cannot be expanded.

another problem in this situation is that only a small part of the file name is displayed on the tab, and most of the time this is not enough to correctly identify it

Weird issue. I have around 200 tabs open atm  (running kate master), but things seem to be working as expected and the editor doesn't increase its width based on the number of tabs I have opened. Is this always reproducible?

This is a won't fix I think because if the tab button is small, it can't display a filename that is larger in size than the button itself.

> Is this always reproducible?
Yes always

And after it gets into that state, I have to close several tabs and maximize the window again to get it back to normal.

I'm using the latest version available on archlinux, 21.12.1

Would you mind sharing your exact tabbar configuration? See "Behaviour"

Comment 5 Bug Janitor Service 2022-02-09 09:49:45 UTC

A possibly relevant merge request was started @ https://invent.kde.org/utilities/kate/-/merge_requests/594

Comment 6 Waqar Ahmed 2022-02-09 11:25:25 UTC

Added some improvements to the UI to fix this case, so marking as resolved:

I assume you were using a large limit in the "tabs limit" which caused this issue. To avoid it for the current release you can do 2 things:
- Use unlimited tabs
- Use a smaller limit

With the next release you can "Allow Tab Scrolling" which will prevent this problem.

Also, please consider providing as much detail as possible when reporting a bug. It is often not obvious or not reproducible without knowing more detail.

Comment 7 Podagric 2022-02-09 12:19:57 UTC

Thank you very much, Waqar Ahmed!

In fact, removing the tab limit was what solved the problem.
Sorry for not providing more details about the bug, I didn't because I really had no idea what setting could be causing this.

Here's what the Behavior tab looked like:
