openbox [--help] [--display DISPLAY] [--id ID] [--root] [--] [PROPERTY ...]
obxprop is a tool for displaying the properties on an x window.
This tool has a similar functionality to xprop, but obxprop allows you to see UTF-8 strings as text.
You may use the --id option to specify a window identifier, otherwise obxprop will allow you to select a window by clicking on it.
Primarily, this tool exists for Openbox users to see the value of the _OB_APP_NAME, _OB_APP_CLASS, _OB_APP_ROLE, and _OB_APP_TYPE properties, which Openbox uses for matching windows against user-defined application rules.
These are the possible options that openbox accepts:
Similar to xprop, you may pass one or more property names to have openbox limit its output to only the properties requested.
openbox (1), openbox-session(1), openbox-gnome-session(1), openbox-kde-session(1).
