Hello again good people,
My editor extends GraphicalEditorWithPalette and I also use a toolbar of
supported actions. Some of my actions run certain tests on my models in the
editor, and therefore I wish to cause some of the actions (such as adding
new nodes, connections or deleting them) both from the palette and the
toolbar - to be disabled during those tests (and enabled when the tests are
done). In other words, what is the best way to cause my editor to be
"read-only" at certain times ?
Thanks in advance,
Dj Shark

Hello again Eric,
Thanks for the tips, I did manage to disable/enable the needed actions in
the toolbar, however I still face two problems:
1. During the mentioned tests, I wish to cause my whole Graphical Editor to
be "read-only" -> no Drag n' drop allowed and no modifying the current
editparts (like changing their location or size), what method should be
called (possibly from the graphical editor itself) to acheive this ?
2. I did manage to "reach" the pallete - but I can only get the tool
entries, and not the tools themselves - I tried all the methods that exist
in the tool entries classes (like setVisable, or
setUserModificationPermission) but the tools themselves are still enabled (I
can create new nodes and connections).
Perhaps if I were to be able to force my graphical editor to be "read-only",
then the tools themselves wouldn't work. Or maybe there is a way to get the
tool from the tool entry ?
Thanks again for all your help,
Dj Shark

Maybe you could do this centrally by extending EditDomain to have
isReadOnly(), and add the necessary checks everywhere.
Or by telling the CommandStack not to execute any commands.

You can disable the entire SWT Control by calling Control.setEnabled(false).
I'm just wondering, if you are running a test, why do expect someone to be
clicking the mouse?

Hello Randy,
Unfortunately, extending EditDomain is not an option.
In addition, since I do not see any public method in class CommandStack that
allows me to disable the commands (like: canExecute(false)) - I assume your
solution is the same principle as the solution of extending EditDomain, and
therefore it too isn't an option.
Regarding Control.setEnabled(false) - I tried that doing the following from
my graphical editor: I get the editor's graphical viewer, from it I get the
control and to that control I do disable.
It works fine (it "freezes" the entire canvas area); Though, I am a little
greedy: Is there a way to disable all editing actions/tools, but still allow
those which are non-editing such as the scroll pane to be active ? Or even
allow the user to select any of the nodes and connections - but not change
any of their properties like size, location, etc. Or delete them, or copy &
paste, etc. ?
Btw, Even after the "freeze" I'm still able to use my outline for
navigation - which is desired, since it's a non-editing action...
Regarding the tests -> These tests are actions on a special bar that "my
client" can run when he or she wants to. I assume I have an adversary
client, who may wish to delibrately try to edit whilst running the tests,
thus causing instability or worse...(Example: a test that checks if all
nodes are alligned - the test is run in animation (You see the editor
highlight each node it passes - this shows that test's progress), if the
user can still move the nodes while the test progresses, then that test is
useless. On the other hand, I do want the user to
see the animation (and not just progress bar...).
Thanks for all the help,
Dj Shark

Test could add itself as a listener to the CommandStack. If the user does
anything, the test will be notified of the change. I don't think you can do
any better, given the presence of popup menus, toolbar actions, and key
accelerators.
