How to add one window in the item of MultiColumnList

[ogre2012]

in the Demo7 Sample,there is something about TaharezLook/MultiColumnList type window.
first, I showed one image in one item of the MultiColumnList.

Code: Select all

mclbox->setItem(new MyListItem("[colour='FFFF6600']284ms[image='set:TaharezLook image:MouseArrow']"), 2, 4);

But when I add one window in the item, it doesn't show the window. And I am sure of creating the window successfully.

Code: Select all

  mclbox->setItem(new MyListItem("123.320.42.242  [window='Demo7/Window1/Radio1']"), 1, 3);

How to make it sure?
And if we can't add one window in the item, feel that it is a pity.
