PullDown menu provides the top (always visible) part of these menus.
|
|
|
65 |
It controls display of its menus, which become visible when one of the
|
|
|
66 |
PullDownMenus entries is pressed.

A PullDownMenu itself consists of a single row of labels, which activate
|
|
|
69 |
a pulled menu when clicked. Entries may be empty (i.e. have no menu)
|
|
|
70 |
and empty entries may (optionally) also perform some action when clicked.
|
|
|
71 |
An entries selector is used as the key to define and access submenus
|
|
|
72 |
and (for empty entries:) the selector sent to the receiver of the menu.
