this one is a ListView with a selected line (which is shown highlighted) |
| 38 | 67 |
If multipleSelectionsOk is true, it is also allowed to shift-click multiple |
68 |
entries. |
|
| 63 | 69 |
If toggleSelect is true, clicking toggles (i.e. click on a seleted item |
70 |
will deselect). |
|
| 31 | 71 |
|
| 38 | 72 |
Whenever the selection changes, an action-block is evaluated, passing the |
73 |
current selection as argument. |
|
74 |
Currently, the selection can be nil, aNumber or a collection of numbers; |
|
75 |
this will change to be either nil or a collection, making selection handling |
|
| 70 | 76 |
easier in the future. (this stupid behavior is due to the multiple |
77 |
select feature being added later - the first implementation used to support |
|
78 |
only single selections). |
|
79 |
||
| 59 | 80 |
The actionBlock is called with the current selection (single number or |
81 |
collection of numbers) as argument. |
|
82 |
||
83 |
Also, to support ST-80 MVC-style use, the model (if nonNil) is notified |
|
| 119 | 84 |
by the change mechanism (performs changeMsg). |
| 59 | 85 |
|
| 60 | 86 |
Before actually adding entries to the the selection, a checkBlock (if non-nil) is evaluated |
87 |
passing the number of the entry whch is about to be selected as argument. |
|
88 |
The select change operation is only done if this returns true. This allows |
|
| 59 | 89 |
interception of select, for example to query the user if he/she wants to save |
| 60 | 90 |
the old contents before (see uses in SystemBrowser and FileBrowser), or to |
91 |
disable individual entries. |
|
| 31 | 92 |
|
| 38 | 93 |
It is also possible to select entries with the keyboard; use the cursor up/ |
94 |
down keys to select prev/next, Home- and End-keys to select first/last. |
|
95 |
Use the return key to apply the double-click-action to the current selection. |
|
96 |
Also, alphabetic keys will select the next entry starting with that key. |
|
97 |
||
98 |
The keyboard behavior can be further controlled with the keyActionStyle |
|
99 |
instance variable (see SelectionInListView>>keyActionStyle:). |
|
100 |
||
| 59 | 101 |
Finally, ignoreReselect controls if pressing on an already selected item |
102 |
triggers the action or not. For some applications it is useful to allow |
|
103 |
reselects (for example, the SystemBrowsers method-list updates the |
|
104 |
source code in this case). |
|
| 38 | 105 |
|
| 60 | 106 |
Currently, some limited form of line attributes are supported. These |
107 |
are kept in the instance variable lineAttributes. |
|
108 |
This may change (using mechanisms similar to MultiColListEntry), so |
|
| 63 | 109 |
be prepared. (dont use the listAttributes instvar directly; if possible, |
110 |
use MultiColListEntry or subclasses of it. |
|
| 120 | 111 |
|
| 63 | 112 |
Although currently based on the listAttributes instVar, the implementation of |
| 120 | 113 |
text attributes will be changed in the near future (when Text/DisplayText are |
114 |
available). |
|
115 |
However, the protocol will probably be kept for backward compatibility |
|
116 |
(i.e. use #attributeAt: / #attributeAt:put etc. - at least, these are easy to find |
|
117 |
when migrating to the new attributed text handling). |

SelectionInListView can be used both in the ST/X way, using action blocks |
