saveable view [message #336854]

Hi All,

I have implemented a view with actions to modify a model. I am able to
detect changes on my model but I am unable to enable the save button.

In the createPartControl() method, I call this method:

private void hookGlobalActions()
{

getViewSite().getActionBars().setGlobalActionHandler(ActionF actory.SAVE.getId(),
new SaveAction());
}

I can detect changes and make my view in the dirty state but still, my
action button is disabled.

Any idea ?

thx.

Your view should implement ISaveablePart.

A view part already implements this interface. I have overriden
corresponding methods but still, no save action allowed !

As Prakash says, you must implement the methods in ISaveablePart (and
make sure you fire PROP_DIRTY when your view dirty state changes, or no
one will care)

You don't use setGlobalActionHandler(*) since the save action is not
retargetable.

As I said before, changes are detected because I fire PROP_DIRTY but the
save action is not enabled ! Is it possible to enable it into a view ? I
guess it is since I have seen such example like papyrus uml editor into
which models can be edited from the outline view.

What save action? Are you running in the IDE or your own RCP app? In
the IDE, save is managed by org.eclipse.ui.actions.ActionFactory.SAVE

The protocol is simple. If the view is active and returns true from
isDirty() then the save action (provided by the ActionFactory and
registered properly in WorkbenchActionBuilder) is enabled. If the view
is active and its dirty state changes it must fire the PROP_DIRTY, but
it is good form to always fire PROP_DIRTY when changing the dirty state.

Is there any document explaining that ? It does not seem that clear for me !
