This adds a tab
|
|
|
|
andlabs/ui is goofy in the sense that you have to determine
|
|
if the ui.Window already has a tab in it. If it does, then
|
|
you need to add this tab and not run SetChild() on the window
|
|
or instead it replaces the existing tab with the new one
|
|
|
|
I work around this by always sending a Toolkit that is a tab
|
|
once there is one. If you send a Window here, it will replace
|
|
any existing tabs rather than adding a new one
