this one is a ListView with a selected line (which is shown highlighted)
|
|
38
|
61 |
If multipleSelectionsOk is true, it is also allowed to shift-click multiple
|
|
|
62 |
entries.
|
|
31
|
63 |
|
|
38
|
64 |
Whenever the selection changes, an action-block is evaluated, passing the
|
|
|
65 |
current selection as argument.
|
|
|
66 |
Currently, the selection can be nil, aNumber or a collection of numbers;
|
|
|
67 |
this will change to be either nil or a collection, making selection handling
|
|
|
68 |
easier in the future.
|
|
31
|
69 |
The actionBlock is called with the current selection as argument.
|
|
|
70 |
|
|
38
|
71 |
It is also possible to select entries with the keyboard; use the cursor up/
|
|
|
72 |
down keys to select prev/next, Home- and End-keys to select first/last.
|
|
|
73 |
Use the return key to apply the double-click-action to the current selection.
|
|
|
74 |
Also, alphabetic keys will select the next entry starting with that key.
|
|
|
75 |
|
|
|
76 |
The keyboard behavior can be further controlled with the keyActionStyle
|
|
|
77 |
instance variable (see SelectionInListView>>keyActionStyle:).
|
|
|

|
|
