You can obtain
-.Aq class
+.Aq class ,
+.Aq instance
and
.Aq name
by running
and then clicking on the desired window.
In the following example the main window of Firefox was clicked:
.Bd -literal -offset indent
-$ xprop | grep WM_CLASS
+$ xprop | grep -E "^(WM_CLASS|_NET_WM_NAME|WM_NAME)"
WM_CLASS(STRING) = "Navigator", "Firefox"
+WM_NAME(STRING) = "spectrwm - ConformalOpenSource"
+_NET_WM_NAME(UTF8_STRING) = "spectrwm - ConformalOpenSource"
.Ed
.Pp
-Note that grepping for WM_CLASS flips class and name.
+Note that
+.Xr xprop 1
+displays WM_CLASS as:
+.Bd -literal -offset indent
+WM_CLASS(STRING) = "<instance>", "<class>"
+.Ed
In the example above the quirk entry would be:
.Bd -literal -offset indent
quirk[Firefox:Navigator] = FLOAT
.Xr grep 1 :
.Bd -literal -offset indent
$ WINDOWID=`xprop \-root _NET_ACTIVE_WINDOW | grep \-o "0x.*"`
-$ xprop \-id $WINDOWID WM_NAME | grep \-o "\\".*\\""
+$ xprop \-id $WINDOWID _NET_WM_NAME | grep \-o "\\".*\\""
.Ed
.Pp
A window can be focused by sending a _NET_ACTIVE_WINDOW client message
