title: How to set up Avalon docking manager to resize like VS?
body: <p>I am using Avalon in my WPF app.  I want a window similar to that of Visual Studio, Tools on the left, then the documents in the middle and the Properties on the right.  I managed to do that with this code:</p>
  
  <pre><code>&lt;Window x:Class="WpfApplication1.Window1"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:ad="clr-namespace:AvalonDock;assembly=AvalonDock"
          xmlns:local="clr-namespace:WpfApplication1"
      Title="Window1" Height="600" Width="800"&gt;
      &lt;Grid&gt;
          &lt;ad:DockingManager x:Name="dockManager" RenderTransformOrigin="0,0"&gt;
              &lt;ad:ResizingPanel Orientation="Vertical"&gt;
                  &lt;ad:ResizingPanel Orientation="Horizontal" &gt;
                      &lt;ad:DockablePane&gt;
                          &lt;ad:DockableContent Title="Toolbox" Width="100"&gt;
                              &lt;TextBox /&gt;
                          &lt;/ad:DockableContent&gt;
                      &lt;/ad:DockablePane&gt;
                      &lt;ad:DocumentPane x:Name="documentsHost" OverridesDefaultStyle="True"&gt;
                          &lt;ad:DocumentContent Title="File1.doc"&gt;
                              &lt;RichTextBox/&gt;
                          &lt;/ad:DocumentContent &gt;
                          &lt;ad:DocumentContent Title="File2.doc"&gt;
                              &lt;RichTextBox/&gt;
                          &lt;/ad:DocumentContent &gt;
                      &lt;/ad:DocumentPane&gt;
                      &lt;ad:DockablePane&gt;
                          &lt;ad:DockableContent Title="Project Explorer"&gt;
                              &lt;TextBox /&gt;
                          &lt;/ad:DockableContent&gt;
                      &lt;/ad:DockablePane&gt;
                  &lt;/ad:ResizingPanel&gt;
                  &lt;ad:DockablePane&gt;
                      &lt;ad:DockableContent Title="Output"&gt;
                          &lt;TextBox /&gt;
                      &lt;/ad:DockableContent&gt;
                  &lt;/ad:DockablePane&gt;
              &lt;/ad:ResizingPanel&gt;
          &lt;/ad:DockingManager&gt;
      &lt;/Grid&gt;
  &lt;/Window&gt;

  <p>The problem is that when I resize any of them, they all resize to keep their proportion.  This is not what I want, I want it to be like VS where just the document window in the middle resizes with.</p>
  
  <p>I would appreciate any help since I have been fighting with this for a few days now :(</p>
