Tabbed dockable windows

[Thomas Klaus]

Hi,

We are using dockable windows in Visio created with C#. Now we want to
add two dockable Windows as tabbed dockable Windows (not side by
side). Programmatically we didn't get that to work. Is there a
solution for this problem?

Here is the code section we are using to create a dockable window:

--snip
this.visAttributeExplorer =
VisioApplication.Instance.ActiveWindow.Windows.Add(
ResourceHelper.GetStringValue(Constants.KEYS_PM_ATTRIBUTEEXPLORER),
Visio.tagVisWindowStates.visWSDockedRight |
Visio.tagVisWindowStates.visWSVisible,
Visio.tagVisWinTypes.visAnchorBarAddon,
0, 0, 250, 400, null, null, null);
this.windowId = this.visAttributeExplorer.ID;
int parent = this.visAttributeExplorer.WindowHandle32;

IntPtr child = this.attributeExplorerForm.Handle;
SetWindowLong(child, GWL_STYLE, WS_CHILD | WS_VISIBLE);
SetParent(child, parent);
// move twice to avoid refresh problems
MoveWindow(child, 0, 0, 100, 100, true);
MoveWindow(child, 0, 0, 250, 400, true);
--snip

If we are doing this twice, the two dockable windows are always side
by side.

Any help would be greatly appreciated.

Thanks,
Thomas Klaus
