Re: [Mono-winforms-list] TreeView.TreeViewNodeSorter seem to have no effect
Hey!
This should be fixed in rev 155655 (svn).
Thanks,
Carlos.

I finally managed to figure out under what circumstances the bug
shows. I have a single root node, creatively labeled root. In that
case TreeView ignores the sorter and sorts alphabetically. Here is my
simple Compare() that is supposed to sort nodes in reverse
alphabetical order:
public class SorterClass : System.Collections.IComparer
{
public int Compare(object a, object b)
{
int res = string.Compare(((TreeNode)a).Text,
((TreeNode)b).Text);
res *= -1;
return res;
}
}
And here is a short example that creates TreeView:
invTree = new TreeView();
invTree.Dock = DockStyle.Fill;
invTree.TreeViewNodeSorter = new SorterClass();
Controls.Add(invTree);
TreeNode root = new TreeNode(My root);
invTree.Nodes.Add(root);
for (char c = 'A'; c = 'Z'; c++)
{
TreeNode n = new TreeNode();
n.Text = c.ToString();
n.Name = c.ToString();
for (int i=0; i20; i++)
{
TreeNode inside = new TreeNode(i.ToString());
n.Nodes.Add(inside);
}
root.Nodes.Add(n);
}
invTree.Sort();
Two observed behaviors differ from .net
1) Bug, Setting TreeViewNodeSorter has no effect if there is only one
top level node. (actually it does have an effect of turning on
sorting, just that the Compare() is never called and sorting is done
by a default system function).
2) Different behavior. On Windows under .NET one does not need to
explicitly call Sort(). Nodes are sorted as they are inserted.

Hello,
I have had this problem with both 2.4.2.3 and 2.6.3. Identical code
works on .net side, in mono's TreeView sorting is always alphabetic
and my Compare() never gets called.

Hi,
I'm trying to cure a few last quirks an an application I'm porting
from windows. The problem I'm having is that setting
TreeView.TreeViewNodeSorter seem to have no effect. The nodes gets
sorted alphabetically and Compare() in my IComparer class never gets
called. Any ideas?
Also TreeView seem to be missing [+] and [-] images next to the nodes
that can be expanded and collapsed.

Re: [Mono-winforms-list] TreeView.TreeViewNodeSorter seem to have no effect
Just to clarify, I don't get any error messages either, it just doesn't use the custom IComparer class I specify. Are you able to sort nodes in say reverse alphabetical order? If yes, I will try to cook up a small test case. On Tue, Mar 23, 2010 at 7:03 PM, Carlos Alberto Cortez calberto.cor...@gmail.com wrote: Hey!
