See bug 661753: TreeNode clones aren't complete, some properties are missing.
This is the code I have so far (in TreeNode.cs):
public virtual object Clone()
{
TreeNode tn = (TreeNode)Activator.CreateInstance
(GetType ());
tn.name = name;
tn.text = text;
tn.image_key = image_key;
tn.image_index = image_index;
tn.selected_image_index = selected_image_index;
tn.selected_image_key = selected_image_key;
tn.state_image_index = state_image_index;
tn.state_image_key = state_image_key;
if (nodes != null) {
foreach (TreeNode child in nodes)
tn.nodes.Add ((TreeNode)child.Clone ());
}
if (context_menu != null) {
tn.context_menu = new ContextMenu();
foreach (MenuItem item in
context_menu.menu_items)
tn.context_menu.menu_items.Add
(item.CloneMenu ());
}
if (context_menu_strip != null) {
tn.context_menu_strip = new ContextMenuStrip();
//foreach (ToolStripItem item in
context_menu_strip.Items)
// tn.context_menu_strip.Items.Add
(item.Clone ());
}
tn.tag = tag;
tn.check = check;
tn.tool_tip_text = tool_tip_text;
if (prop_bag != null)
tn.prop_bag = OwnerDrawPropertyBag.Copy
(prop_bag);
return tn;
}
However, the problem is the commented lines for context_menu_strip: I can't
clone the ToolStripItem objects, as it has no clone method.
So, what would be the best way to clone the ToolStripItem objects? Do I have to
copy each property manually (as in here:
http://blogs.msdn.com/b/jfoscoding/archive/2005/09/28/475177.aspx)? Hopefully
not... If I have to, maybe I should make it an internal method inside
ToolStripItem, so other objects can reuse it...?
Thanks for the help.
PS: the original code used both private fields and public properties, but
mostly private fields, so I homogenized the whole thing and used private fields
everywhere (as I don't think it's necessary to run the property code in this
case). Maybe I should have used public properties instead... *shrugs*
