Hi all,
I want to allow the users of my Eclipse 3.0 code editor to set the text
background.
For example, set the background to black and simulate a console/terminal
style.
Someone, in this newsgroup, previously suggested setting
AbstractTextEditor.PREFERENCE_COLOR_BACKGROUND via the IPreferenceStore.
This does work - just a little too much ;-) Every single editor (presumably
all those that derive from AbstractTextEditor) now have the colour I
specified in the preference store.
What I would like is, for my particular editor (which subclasses
org.eclipse.ui.editors.text.TextEditor) to have it's own background colour
that doesn't "overflow" into any other types of editor (all instances of
*my* editor can have this color, I just dont want the JDT/etc.. to use it!).
Q: Is this possible?
- If so, any hints?
I'm thinking that it might be a case of accessing the underlying SWT
widget(s) and manipulating their properties... but I can't find any obvious
route down to them (probably for a good reason).
Cheers,
Jack

Simply provide your own, private preference store in your text editor
implementation, and set the preference just in there, instead of using
the EditorsUI.getPreferenceStore

The problem with this is that your own preference store must provide all
other preferences that AbstractTextEditor also looks from the
EditorsUI's preference store, no?
May be one should write desired pref values into the EditorsUI.

I think I found the solution.
Please http://www.eclipse.org/articles/Article-Preferences/preferen ces.htm
(See the section "Propagating Values With IPropertyChangeListener".)
Listen for the property changes in your pref settings. This means your
editor must install such listener. Once you get the change event, your
editor simple get the source viewer, which, in turns, can call
getControl() that returns a StyledText, then do a
StyledText.setBackgound(Color).

Here is how:
Basically, override the texteditor's createPartControl()...(Make sure to
call super.createPartControl() then do your stuff!) At the end, before
exiting the method, call
getSourceViewer().getStyledText().setBackground(Color yourColor). That is.
The AbstractTextEditor reads a lot of preferences from the
EditorsPluin's preference store. It's not a good idea to give it a new
preference store unless you are able to provide all the other
preferences as well.
The above solution works well.

You can use a org.eclipse.ui.texteditor.ChainedPreferenceStore to create
an aggregated view of multiple preference stores. Pass your custom
store as the first one in order to shadow the one from EditorsUI:
IPreferenceStore yourPluginPreferences= ...;
IPreferenceStore editorPrefs= EditorsUI.getPreferenceStore();
IPreferenceStore[] stores= { yourPluginPreferences, editorPrefs };
IPreferenceStore combined= new ChainedPreferenceStore(stores);
Now reading from 'combined' will return the preference found in your own
store if present, and will otherwise read through to the editor preferences.
