how to rename or change icon to a uitreenode , I try jtree.setEditable(true), but the name can not be modified

I am using uitree in a MATLAB-GUI, too. Can you give me an explanation, how it is possible to modify the content of “handles” in the ExpandFcn of uitree. I always have the problem, that the changings are visible when I am in the function call – afterwards they are deleted. Is there a possibility to make changes outside the original GUIDE-Callbacks?

Thank you & best regards
Paul

@Yair: Thank you very much for your answer!
In my MATLAB-GUI I have a pushbutton for opening a new file. In the Callback of this pushbutton I am using the following code:

% --- Executes on button press in open_pb.
function open_pb_Callback(hObject, eventdata, handles)
% hObject    handle to open_pb (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
[filename,pathname]=uigetfile('*.mat', 'File zum Laden auswählen');
a=[pathname,filename];
data = load(a);
name = fieldnames(data);

handles.data = cell(2,1);
handles.data{1} = data;

handles.root = uitreenode('v0', filename, filename, [], false);
handles.tree = uitree('v0', hObject,'Root', handles.root,'ExpandFcn', @(obj, ev)myExpfcn4(obj, ev, hObject, handles));

% Update handles structure
guidata(hObject, handles);

When I execute this pushbutton, I get the following error message:

Error using uitree_deprecated
Unrecognized parameter.

Error in uitree (line 102)
	[tree, container] = uitree_deprecated(varargin{2:end});

Have you got an idea what is my principal problem?

Thank you very much for your response.

Best regards,

@Sebastian – did you try to simple create a new uitreenode for the new file and then set the tree’s Root property to this new node?

I am using the uitree inside a MATLAB GUI. Basically I want to browse in .mat-files (simulation results). Until now I am able generate a uitree, but I am not able to delete it and load another .mat-file. Can you help me how it is possible to use uitrees for different .mat-files?

Thank you very much,
Sebastian

My code example for the generation of a uitree:

import javax.swing.*;
warning('off', 'MATLAB:hg:JavaSetHGProperty');

[filename,pathname]=uigetfile('*.mat', 'File zum Laden auswählen');
a=[pathname,filename];
data = load(a);
name = fieldnames(data);

handles.data = cell(2,1);
handles.data{1} = data;

handles.root = uitreenode('v0', filename, filename, [], false);
handles.tree = uitree('v0', hObject,'Root', handles.root,'ExpandFcn', @(obj, ev)myExpfcn4(obj, ev, hObject, handles));
set(handles.tree, 'Units', 'normalized', 'position', [0 0 0.25 1]);
set(handles.tree, 'NodeWillExpandCallback', @(obj, ev) nodeWillExpand_cb4(obj, ev, hObject, handles));
set(handles.tree, 'NodeSelectedCallback', @(obj, ev)nodeSelected_cb4(obj, ev, hObject, handles));

handles.t = handles.tree.Tree;
set(handles.t, 'MousePressedCallback', @mouse_cb);

warning('on', 'MATLAB:hg:JavaSetHGProperty');

I don’t think there is a simple answer. If you wish me to investigate this (for a consulting fee) then send me an email.

I mean if I go as per your example document http://undocumentedmatlab.com/blog/customizing-uitree-nodes-2 , I want checkbox only for the ‘child node’ and options below it and not the node where its written ‘file A’ and ‘file B’. Is it possible. If so, please suggest me the code for it
