find-or-make-application-window

Arguments: name make-function &rest args

Returns a window that is intended as a non-modal window for an application. If the window has previously been created by calling find-or-make-application-window or add-application-window and it has not been closed, then the existing window is returned. Otherwise make-function is called to create the window, and that new window is returned.

This function calls find-application-window to find an existing matching window if any. It will pass name as the key argument to find-application-window, and pass the current process as the subkey argument, and t as the always argument.

name is an arbitrary symbol for identifying the window. No two windows that are made with find-or-make-application-window or find-or-make-pop-up-window should use the same name.

make-function should be the name of a function that takes args as its argument list, and which makes and returns a window whose name is name.

See also find-application-window, add-application-window, and remove-application-window.
