x:*xwindows* [variable]

a list of all windows including subwindows created and maintained by EusLisp.

x:*xwindow-hash-tab* [variable]

a hash table to look up the xwindow object by its drawable ID. In the event structure obtained by x:nextevent is a window ID, and x:window-main-loop calls x:event-window to know the corresponding xwindow object using this table.

xflush [function]

sends all commands retained in the Xlib command buffer to Xserver. Since Xlib buffers output to Xserver, commands you issued commands to Xserver are not executed immediately. This is necessary to decrease network traffic and the frequency of process switching. To flush the command buffer to see the effects of the commands, use xflush or send :flush message to xwindow objects.

find-xwindow subname [function]

Each xwindow may have name specified at the creation time. Find-xwindow looks in the *xwindows* list and returns a list of windows that have 'subname' as a substring of its name.
