hello -
i'm trying to create a plugin that will display a lock image icon if
the file is in read-only mode. i've got that working ok, however i'm a
bit stuck trying to figure out how to monitor when the Read Only
attribute is changed so i can fire a label change event.
can anyone point me in the right direction?
thx!!!

thx for the response!
would there be any way to tell that those attributes changed at all?
i wrote a plug-in that will display a lock image over top of a file if it is
read-only (i got tired of typing and not seeing any text :) and even added
a context menu option to toggle the read-only status.
the above works well for all instances, except when someone changes the
read-only attribute thru the properties dialog.
so when i get down to it, i guess i want to know if it's possible to fire off
a call to my plugin's decorator to cause a refresh (short of trying to find
that chunk of eclipse code and "hacking" it).
thx again!

Sorry, it's not possible. The read only state of each file is not
stored in memory, and there is no filesystem notification when that
attribute changes. The platform core doesn't even know when this state
changes.
