<descr>
<p>
<var>ReadOnly</var> is a <var>Boolean</var> property which indicates whether
the text for the <var>TTreeNode</var> instances in Items can be edited in the
control. When ReadOnly is set to <b>False</b>, the <var>BeginEditing</var>
method is <b>not</b> called when the <b>F2</b> key is pressed, or when the Left
mouse button is double clicked. The default value for the property is
<b>True</b>.
</p>
<p>
The property value is <b>True</b> when <var>tvoReadOnly</var> has been
included in the <var>Options</var> for the control. Setting a new value for
the property causes tvoReadOnly to be included in or excluded from the values
in Options. Changing the value to <b>False</b> causes the
<var>EndEditing</var> method to be called.
</p>
<p>
The ReadOnly property was changed to <b>True</b> because the shell tree view
does not automatically propagate changes to a tree node caption to the file
system. The previous behavior was confusing because the user was able to rename
a node but had to notice that the change was not persistent without additional
code.
</p>
<p>
Applications using the shell controls only for selecting files and folders are
not affected. In "file-manager" application types, however, the ReadOnly
property must be changed explicitely to <b>False</b> so that the user can edit
items/nodes again.

<short>
Disables editing of list items on the shell control when set to <b>True</b>.
</short>
<descr>
<p>
<var>ReadOnly</var> is a <var>Boolean</var> property used to enable or
disable editing of captions for list items at run-time. When ReadOnly is set
to <b>True</b>, the editor for the control cannot be activated using a mouse
double Click or by pressing the F2 function key.
</p>
<p>
The default value for the property is <b>True</b>, and indicates that item
editing is not allowed.
</p>
<p>
ReadOnly is one of the TListViewProperty values included in the
TListViewProperties set type and exchanged with the widgetset class. The
property value is read from and written to the TCustomTreeview widgetset
class instance when its handle is valid. Changing the value for the property
causes the widgetset class to be updated with the new value.
</p>
<p>
The ReadOnly property was changed to <b>True</b> because the shell list view
does not automatically propagate changes in a list item to the file system. The
previous behavior was confusing because the user was able to modify a list item
but had to notice that the change was not persistent without additional code.
</p>
