Bug 227638 Tree with SWT.VIRTUAL not working
Reported: 2008-04-17 15:51:09 | Status: resolved wontfix

The WPF TreeView widget does not virutalize its items like ListView can/does. We use OnRender to send our SetData event that tells the user to populate the SWT TreeItem or TableItem. Because WPF TreeView widget does not use a virtualized panel to layout it's children, all of the the children are rendered at the same time, regardless of whether they are visible or not.
