TextEditor [message #212971]

Hi,

I am extending from org.eclipse.ui.editors.text.TextEditor.
At any time the user needs to save the contents afetr making changes the
user presses save in the appropriate menu.
Before the actual save I wish to intervene and make some checks.

Q1) How do I get the content that corresponds to what is being displayed
in the editor(- thats the text I need to validate before it actually gets
saved)?

I presume I must do all this inside the doSave(IProgressMonitor monitor)
method.

Q2) Should I use the documentProvider?How exactly?

TextEditor yourEditor;

IDocument document=
yourEditor.getDocumentProvider()
.getDocument(yourEditor.getEditorInput());

then, look at the document.

Well if you implement a DocumentProvider you can override

DocumentProvider.doSave(IProgressMonitor monitor, Object element,
IDocument document, boolean overwrite)

and then perform validation there.

To implement just take a look at what the sample editor does. (
Basically
just subclass FileInputDocumentProvider. )

The make sure you go through the document provider when you
open,save,close documents.

If you want to make sure that if multiple editors open the same file they
use the
same document instance you will want to make sure your document provider
is
a singleton. To do this you will want to declare it as an extension and
then
make sure you only access it through the DocumentProviderRegistry.

Thanks that worked. I am now displaying a messagebox wherein I am giving
the user a warning and allowing the user to save if the user insists.

Q1) What are these methods meant for-"createStatusControl,
doRevertToSaved, sanityCheckState, updatePartControl, updateStatusField,
validateState, updateState, safelySanityCheckState,
handleExceptionOnSave"?

Q2) I am not using these methods should I? Am I missing out on something?

Read the Javadoc.

Read the Javadoc and find out it applies to your code.
