如何在Eclipse工具栏中启用保存操作？

Question

I am working under Eclipse plug-in development. I have implemented two view parts to view and change some objects. Each view part implements ISaveablePart to save modified objects and enable save button on toolbar.

The problem is: when I select my objects in Project Explorer , Save button isn't enabled, only Save All is enabled.

So I'd like to know is there any ability to enable Save button in this case?

You must first implement ISaveablePart , as you have mentioned above.

You have to fire an event (see IWorkbenchPartConstants.PROP_DIRTY ), which will in turn ask your editor whether it's dirty ( ISaveablePart#isDirty() ). If the answer is true , then the save button will be enabled.

See FormEditor#editorDirtyStateChanged() for an example.
