WARNING: This feature is not supported in MATLAB
and the API and functionality may change in a future release.
UITREENODE(Value, Description, Icon, Leaf)
creates a tree node object for the uitree with the specified
properties. All properties must be specified for the successful
creation of a node object.
Value can be a string or handle represented by this node.
Description is a string which is used to identify the node.
Icon can be a qualified pathname to an image to be used as an icon
for this node. It may be set to [] to use default icons.
Leaf can be true or false to denote whether this node has children.
Example:
t = uitree('Root', 'D:\')
%Creates a uitree widget in a figure window with which acts as a
%directory browser with the D: drive as the root node.
surf(peaks)
f = figure
t = uitree(f, 'Root', 0)
%Creates a uitree object in the specified figure window which acts as
%a MATLAB hierarchy browser with the MATLAB root (0) as the root node.
root = uitreenode('S:\', 'S', [], false);
t = uitree('Root', root, 'ExpandFcn', @myExpfcn, ...
'SelectionChangeFcn', 'disp(''Selection Changed'')');
%Creates a uitree object with the specified root node and a custom
%function to return child nodes for any given node. The function
%myExpfcn is a user defined m-file in the MATLAB path.
% This function should be added to the path

try
count = 0;
ch = dir(value);
for i=1:length(ch)
if (any(strcmp(ch(i).name, {'.', '..', ''})) == 0)
