implements the tabs-view component of a noteBook.
|
|
|
44 |
May also be used on its own (without a surrounding noteBook).
|
|
|
45 |
|
|
|
46 |
The functionality is basically the same as provided by a
|
|
|
47 |
PopUpList or SelectionInListView, in that a valueHolder
|
|
|
48 |
gets a value assigned corresponding to the selected tab
|
|
|
49 |
from a list of possible tabs.
