Returns the [Popup] node instance if one has been set already with [method set_popup]. [b]Warning:[/b] This is a required internal node, removing and freeing it may cause a crash.

Returns [code]true[/code] if the tab at index [code]tab_idx[/code] is hidden. If set on a [Popup] node instance, a popup menu icon appears in the top-right corner of the [TabContainer] (setting it to [code]null[/code] will make it go away). Clicking it will expand the [Popup] node. If [code]disabled[/code] is [code]true[/code], disables the tab at index [code]tab_idx[/code], making it non-interactable.

Setting this to [code]-1[/code] will disable rearranging between [TabContainer]s. If [code]true[/code], tabs are visible. If [code]false[/code], tabs' content and titles are hidden. If [code]true[/code], children [Control] nodes that are hidden have their minimum size take into account in the total, instead of only the currently visible one.
