Window Specific Corner Radius

[Reith77]

Hi

I am trying to get only one specific window to have curved radius.

The window has the property QTILE_BAR as shown in the below xprop output

QTILE_BAR(CARDINAL) = 1
_NET_WM_STATE(ATOM) = _NET_WM_STATE_BELOW
_NET_WM_WINDOW_OPACITY(CARDINAL) = 4294967295
_NET_FRAME_EXTENTS(CARDINAL) = 0, 0, 0, 0
QTILE_INTERNAL(CARDINAL) = 1
WM_STATE(WM_STATE):
		window state: Normal
		icon window: 0x0

I am using the corner-radius-rules config to set a corner radius of 10, but it does not work

corner-radius-rules = [ "10:QTILE_BAR:32c = 1" ];

Am I doing something wrong ??

#     "tooltip", "notification", "combo", and "dnd".
#
# Following per window-type options are available: ::
#
#   fade, shadow:::
#     Controls window-type-specific shadow and fade settings.
#
#   opacity:::
#     Controls default opacity of the window type.
#
#   focus:::
#     Controls whether the window of this type is to be always considered focused.
#     (By default, all window types except "normal" and "dialog" has this on.)
#
#   full-shadow:::
#     Controls whether shadow is drawn under the parts of the window that you
#     normally won't be able to see. Useful when the window has parts of it
#     transparent, and you want shadows in those areas.
#
#   clip-shadow-above:::
#     Controls whether shadows that would have been drawn above the window should
#     be clipped. Useful for dock windows that should have no shadow painted on top.
#
#   redir-ignore:::
#     Controls whether this type of windows should cause screen to become
#     redirected again after been unredirected. If you have unredir-if-possible
#     set, and doesn't want certain window to cause unnecessary screen redirection,
#     you can set this to `true`.

[yshui]

I thought @absolutelynothelix fixed that 🤔

[absolutelynothelix]

@yshui, i think that's something other than #1170. but just to make sure: @Reith77, does it work if you set corner-radius to something other than 0, e.g. 1?

[Reith77]

Using corner-radius-rules, it doesn't.

But just setting corner-radius changes for all windows.

I did some further testing, and using class_g for Alacritty allows me to set corner radius for Alacritty alone, but using QTILE_BAR:32c = 1 doesn't seem to work the same way

[absolutelynothelix]

does qtile bar has any other properties you can attach to or the xprop output provided above is everything that it has?

[Reith77]

That is everything xprop outputed

[Reith77]

It is possible to add properties to the bar using python. In fact the QTILE_BAR is a property I added, that can still be used in conditions right ?

[absolutelynothelix]

you're missing the @ character in your condition, i.e. it should be QTILE_BAR@:32c = 1:

       CLIENT/FRAME is a single @ if the window attribute should be be looked up on client window, nothing if on
       frame window;

I tried this just now, it still doesn't work

[absolutelynothelix]

huh, it makes the opacity-rule option work but doesn't make the corner-radius-rules one 🤔

[Reith77]

I would try to attempt to solve the bug, but I have 0 clue how compositors work 😄, if there is something else I can help with please let me know :)

[absolutelynothelix]

oh, it's indeed another corner-radius-rules bug. nonetheless, your condition was wrong.

[Reith77]

oh, it's indeed another corner-radius-rules bug. nonetheless, your condition was wrong.

Yeah, my bad about that. I didn't really understand the terminology in the documentation and messed up the condition. I have corrected the condition now

[absolutelynothelix]

does applying #1178 fix the issue for you?

[Reith77]

Hey,

I messed up testing, will test again and get back to you

[absolutelynothelix]

are you sure that you're starting the picom that you've just built? the built binary is located in build/src, i.e. it's build/src/picom.

[Reith77]

Hey,

Just tested and it works !!!

I was using the wrong branch 🥲

Thank you for the quick fix !! Much appreciated
