Tab The controlID of the tabitem selected

For Checkbox and Radio controls only the $GUI_CHECKED (1), $GUI_UNCHECKED (4) or $GUI_INDETERMINATE (2) states are returned so the value can be used directly.

For Listview items several states can be returned as $GUI_CHECKED and $GUI_UNCHECKED (only for listview controls with LVS_EX_CHECKBOXES-exstyle and on 'advanced' return) . So use i.e. BitAND(GUICtrlRead($Item, 1),$GUI_CHECKED) to test if the item is checked.

For Treeview items several states can be returned as $GUI_FOCUS, $GUI_EXPAND and $GUI_CHECKED, $GUI_UNCHECKED (only for treeview controls with TVS_CHECKBOXES-style . So use i.e. BitAND(GUICtrlRead($Item),$GUI_CHECKED) to test if the item is checked.
