Description

Any toolbar object may be disabled, by setting its enabled slot to nil. Disabling a toolbar or toolbar component prevents the user from interacting with any buttons contained in it.

All toolbar objects may also have an enabled-function specified. This is called whenever update-toolbar is called. If it returns t, the toolbar object will be enabled; if it returns nil, the object will be disabled.

Notes

The function enabled-function should not display a dialog or do anything that may cause the system to hang. In general this means interacting with anything outside the Lisp image, including files, databases and so on.
