v7.0
Determines the availability of the File menu functions for a
text editor widget control (siControlTextEditor).
By default, if you display the toolbar (explicitly set the siUIToolbar attribute to
true), every function (entry) in the menu will be enabled. However,
you can disable the loading and saving functions by setting the
siUICapability
attribute to one of these values.
Note: Using these values does not affect the Edit menu at all nor
does it change the availability of the rest of the File menu
functions (Recent Files, Preferences, and Print).
