@Jan - I’m willing to bet that the solution for 6.5 is simply a variant of the Matlab 6 syntax. Try to run the following command in Matlab 6.5 to check whether the getOpenDocuments() method was renamed:

methodsview('com.mathworks.ide.editor.EditorApplication')

This does not work on my Matlab 6.5.1, WinXP SP3, JavaVM 1.3.1_01

% So here's the workaround for Matlab 6:
openDocs = com.mathworks.ide.editor.EditorApplication.getOpenDocuments;

There is no getOpenDocuments method for the EditorApplication.
The solution is trivial: Do not use Matlab 6.5… Thanks, Jan

For anyone interested, Jan Simon has just posted a few more useful things that can be done using the Editor handle:

Bring the editor to front:

jEditor.toFront;

Is the editor active currently:

jEditor.isActive;

Perform an action whenever the user activate the editor:

set(jEditor, 'WindowGainFocusCallback', 'disp(''Editor activated'')')

Or the usual function handle callback style.

See further properties:

get(jEditor)

and

methods(jEditor, '-full')

My editor window is docked and that stops title being the ‘Editor - ‘… form. I wanted to get the active document so I could invoke a command to open the directory of the current editor’s file.

Thanks to Aurélien I discovered the following to get the current editor’s file path:

d = com.mathworks.mlservices.MLEditorServices;
fName = d.builtinGetActiveDocument;
path=fileparts(fName.toCharArray');

@Aurélien, in MATLAB >= R2009b you can try

editorservices.closeGroup

And to leave the group up and just close all the open editors

e=editorservices.getAll; e.close

For more about the “less undocumented” way to access the editor, see my new post:

Ruben - that was a hard question that kept me digging for hours. I discovered (via the FindJObj utility) that the bookmarks are displayed in a panel called ‘ExecutionArrowDisplay’ of class com.mathworks.mde.editor.ExecutionArrowDisplay$ExecutionPanel. I do not know whether the list of bookmarks are contained within this object, although I suspect they are. In any case, I did not find a method to programmatically retrieve this list since the ExecutionPanel object does not expose any method to do so.

So, the only way I could find is to loop over all the editor’s open files, and invoke the editor’s default action for (which is the ‘next-bookmark’ action reported by the EditorMacro utility) in a loop until you detect coming back to an earlier line number. It’s ugly, but it should work. The reverse, setting bookmarks, could be done in a similar fashion, using the ‘toggle-bookmark’ action.

I think it could be a great File Exchange utility. Care to try it? If you get stuck I can help out.

Do you know how can I find the bookmarks in the editor? I would like to get all bookmarks and save them on closing Matlab, so that on reopening, they could be restored.
Thx

To close all M-files in the editor, I use:

 
com.mathworks.mlservices.MLEditorServices.closeAll
