Hi, I know its not the right place to ask for this. Or to create to an Issue for. But since I couldn't actually find any place to ask for help, other than r/UnixPorn. Here I am asking for help. Any kinda help is appreciated. Thanks in advance.

The Problem

in bspwmrc added bspc rule -a re state=floating, so the window should open as Floating right? but it isn't doing that... its still tiled. Did restart bspwmrc, tried restarting OS too.

I thought in the rule.... that re a.k.a the application/executable name was supposed to be <class_name>, so I tried setting the ATOMs below including WM_CLASS.

EWMH [Client App Window] (& other ATOMs)

NOTE: I'm using using xcb & this is what I did...

xcb_icccm_set_wm_class(
    XCB_CONN, xcb_win,
    2, "re"
);

I have set

_NET_WM_STATE: _NET_WM_STATE_MODAL using xcb_ewmh_set_wm_state()
_NET_WM_WINDOW_TYPE: _NET_WM_WINDOW_TYPE_NORMAL using xcb_change_property()
WM_NORMAL_HINTS (using icccm)
WM_CLASS & WM_HINTS (using icccm)
_NET_WM_PID
WM_CLIENT_MACHINE (using icccm)

its been more than 48 hours.... i was totally going insane over this....

THIS WORKS:

[FIXED] UPDATE: "<instance_name>\0""<class_name>" 2 (NULL terminated) strings, first one is <instance_name> and actually the second one is class_name
