Now, I was wondering about the window-mwnu-items. In the MCL manual, it
states that the file menu item "Save" is enabled whenever the frontmost
window has a window-save method defined for it, and a subsidiary function
window-needs-saving-p returns true. What I wanted to know is how is
window-needs-saving-p called. How do you tell MCL to check that function
as well as chacking for the window-save method? Do you use the
menu-item-update procedure, or is there something else?
The ccl::save-menu-item-update function is called to enable/disable the
save menu item on the *file-menu*. The function in turn calls
window-needs-saving-p whichb you can specialize for your own windows.
For standard (non-fred) windows, there is no window-needs-saving-p
method. As a result, the save menu item is disabled. All you have to
do is supply a window-needs-saving-p method and a window-save method.
