i3 wm, hide window title bar

gistfile1.md

deprecated

for_window [class="^.*"] border pixel 1
new_window 1pixel

thanks to deviatorslegacy's comment
Document here: https://i3wm.org/docs/userguide.html#_default_border_style_for_new_windows

New way to do it:

default_border pixel 1
default_floating_border pixel 1

Additionally, I could assign color to border when window focus is changed. https://i3wm.org/docs/userguide.html#_changing_colors

That works on i3 version 4.18 (2020-02-18)!

Thank man!!!

2022 still works :)

Thank you!

Thank You! <3

Thanks my homie

Thanks! ^-^

Thx 👍

Thx!

Is there any way of deleting window titles in stacked and tabbed mode?

very thanks!

Hey, I could notice that only with for_window [class="^.*"] border pixel 1 apps like gedit are getting boards.

Since the v4.21 release, the following snippet does not work anymore:

default_border pixel 1
default_floating_border pixel 1

Switching back to the following snippet worked (even tho it has been categorized as deprecated):

for_window [class="^.*"] border pixel 1

In anticipation of a future update that make another change, I actually put both solutions in my config file, like so:

#Hide window title bar
default_border pixel 1
default_floating_border pixel 1
for_window [class="^.*"] border pixel 1

Hope it helps 😄

Thanks @Antiz96 I came here for this 10 sec after you posted it!

@stuvet I'm glad I could help :)

Amazing I just came here to see it coz suddenly my title bar started to show out of nowhere.!

Solved this problem for me ^^

This was exactly the problem I had. Weird change! Thanks for the insight.

Thx!

Also used only

default_border pixel 1
default_floating_border pixel 1

few apps worked, few didn't
added the
for_window [class="^.*"] border pixel 1
now everything works as expected except applications running in wine.
anyone any idea?

Great stuff, thanks a lot!

Thanks a lot for the fix, @Antiz96 . My latest Fedora 35 update picked up 4.21 and I started seeing borders as well... this got me back to normal.

Thanks!

Not directly. It is possible in a fairly easy manner though.
My solution was to set the font to 0 in ~/.config/i3/config . Then just toggle font on and off with this script (since sometimes I do want the titlebar to be there). You need of course to match the font line with your own:

#!/bin/bash

grep "font pango:Terminus (TTF) Medium" ~/.config/i3/config |grep 0

if [ $? -eq 0 ]; then
  sed -i 's/font pango:Terminus (TTF) Medium 0/font pango:Terminus (TTF) Medium 9/' ~/.config/i3/config
else
  sed -i 's/font pango:Terminus (TTF) Medium 9/font pango:Terminus (TTF) Medium 0/' ~/.config/i3/config
fi

i3-msg reload

This leaves a 4px border (I read in another post which Airblader answered) This can easily be removed from the source code. A super simple patch which I just put inside my patches folder in Gentoo:
/etc/portage/patches/x11-wm/i3-gaps/remove-win-decor.patch :

 int render_deco_height(void) {
-    int deco_height = config.font.height + 4;
+    int deco_height = config.font.height;
     if (config.font.height & 0x01)
         ++deco_height;
     return deco_height;

Thanks @qordaz

In case some of you might want to remove the title bar entirely :

int render_deco_height(void) {
     return 0;
}

That's what I did, not sure if that's how it supposed to be done..
