Undo "No border" in KDE

Question

I alt-clicked on a window's title bar and removed the bar by clicking "No border" but now I have no accessible means to restore that window's title bar. Is there a way to open KWin for that specific window? What are my options for restoring the window's border? (Plasma 5, if it's version-specific.)

Focus window:

Alt+F3 ⇒ "more actions" ⇒ uncheck "no border"

Check in Systemsettings > Application Style > Window Decorations

there should be an option to set borders.

or edit the following config file: ~/.config/kwinrc

look for the line: BorderlessMaximizedWindows=true

and either change it to false or comment it out.

Neither of these apply to me. I'm also on Plasma 5. There's no option to set borders, and the line in kwinrc already doesn't exist. – chreekat Jun 29 '18 at 13:47
this setting is non-existent in Plasma 5 – Sajuuk Aug 13 '21 at 13:05
I can clearly hear the voice of a colleague now, he's always around when there's a problem with linux that requires this kind of solution, while in another OS you just press a button. Luckily I've solved with Janghou's answer...and his voice went away :-D – funder7 Jul 29 '22 at 22:31

press Alt+F3 on window with focus:

choose menu item(s): more actions > [deselect] 'no borders'

You should get a message dialog when you 'hide border' that reads something like ... blah, blah. use Alt+F3 to show menu allowing you to do the above with your mouse.

If you are Not getting the message do this (utf-8 editor!): Edit file: ~/.kde4(.kde)/share/config/kwin_dialogsrc Change or Add the Line(s):

[Notification Messages]
altf3warning=true

Save, Done. (no restart necessary)

The first half of your answer duplicates Janghou’s answer. – Scott - Слава Україні Jul 08 '20 at 03:27

I needed to do the same thing, but I didn't find anything relevant in ~/.config/kwinrc.

I found the application-specific settings in ~/.config/kwinrulesrc. I removed them with Vim, and restarted kwin_x11, and restored the border on the program I had previously removed the border from.
