Edit readonly files [message #509932]

I've made a plugin with a custom editor (extends TextEditor).
When I open a readonly-file in this editor, and alter something, a messagebox comes up asking: "File is read-only. Do you wish to make it writable" ... I always click on "No" ... from that time on nothing can be altered in the editor.

How can I get rid of this messagebox and always have the editor in read-only mode when I open a read-only file ?

Did you or anyone else find a solution?

Thanks a lot!
Best regards

No I got no reaction at all ... a bit irritating as this is www.eclipse.org

The message comes from the default file modification validator which is
used for unshared files. The easiest way to change this for your editor
is to use overwrite
org.eclipse.ui.texteditor.AbstractTextEditor.validateState(I EditorInput)
and not call validateState(...) on the extension. Note that you should
only override the case where the file's project is not shared since for
those cases you probably want the validation done by the repository
provider.

Hi,

I'm at the point implementing this ... so I coded beneath in the editor (which extends AbstractDecoratedTextEditor) :

@Override
protected void validateState(IEditorInput newInput)
{
MessageDialog.openInformation(
null,
"validateState", //$NON-NLS-1$
"in"); //$NON-NLS-1$ //$NON-NLS-2$ //$NON-NLS-3$

}

Now everytime I change something (f.e. type 'A') in the editor, or save it, I get the messagedialog ... so that's good.

I know how to check if the editted-file is read-only.

But now, how do I prevent that something is changed in the editor(text) (f.e. after typing the 'A') when I'm in validateState ?

Thx.

I am new to eclipse world, I was using Carbide, which is based on eclipse. I was thinking of creating an extension for it.

Please let me know if there is any way where I can create an extension/plugin so that when I open a file which is readonly, I can handle it instead of the default behaviour? In my case, I should convert the file from readonly to writable, but should also mark it as edited by a source depot tool.

Kindly tell me if this can be done.

Thanks,
Kiran

Google is your friend.

You might try vogella.de for help in writing your first plug-in.
