Capabilities include:

  • The ability to query arbitrary windows on Tk's display
  • Access to and control of X cut buffers
  • Bell frequency, volume, and duration control
  • Access to X drawables, including dumping their contents to Tk images
  • Querying and manipulation of the X event queue
  • Reading of window-manager-related window properties
  • Colormap control

These facilities are provided via xop. The intended purpose of the Xop package is to provide certain low-level X11 facilities required by window managers, but the package need not be used in that way.
