PullDown menu provides the top (always visible) part of these menus. |
56 |
It controls display of its menus, which become visible when one of the |
|
57 |
PullDownMenus entries is pressed. |
|
| 0 | 58 |
|
| 128 | 59 |
A PullDownMenu itself consists of a single row of labels, which activate |
60 |
a pulled menu when clicked. Entries may be empty (i.e. have no menu) |
|
61 |
and empty entries may (optionally) also perform some action when clicked. |
|
62 |
An entries selector is used as the key to define and access submenus |
|
63 |
and (for empty entries:) the selector sent to the receiver of the menu. |
