When the TabStyle is resolved to StateButtons, the tabs are displayed as state buttons where the selected tab is in the pressed state. By default, there is some space between the state button tabs which can be controlled using the InterTabSpacing. As long as there are a few pixels of space between the state button tabs, a perpendicular line separating the tabs will be displayed when this property is set to true (the default value). This can be helpful when the TabButtonStyle is set to a value that displays the unselected tabs as border less state buttons.
