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.
|
|
31
|
69 |
|
|
38
|
70 |
Whenever the selection changes, an action-block is evaluated, passing the
|
|
|
71 |
current selection as argument.
|
|
|
72 |
Currently, the selection can be nil, aNumber or a collection of numbers;
|
|
|
73 |
this will change to be either nil or a collection, making selection handling
|
|
|
74 |
easier in the future.
|
|
59
|
75 |
The actionBlock is called with the current selection (single number or
|
|
|
76 |
collection of numbers) as argument.
|
|
|
77 |
|
|
|
78 |
Also, to support ST-80 MVC-style use, the model (if nonNil) is notified
|
|
|
79 |
by the change mechanism (performs changeSymbol).
|
|
|
80 |
|
|
|
81 |
Before actually changing the selection, a checkBlock (if non-nil) is evaluated
|
|
|
82 |
and the select-operation is only done if this returns true. This allows
|
|
|
83 |
interception of select, for example to query the user if he/she wants to save
|
|
|
84 |
the old contents before (see uses in SystemBrowser and FileBrowser).
|
|
31
|
85 |
|
|
38
|
86 |
It is also possible to select entries with the keyboard; use the cursor up/
|
|
|
87 |
down keys to select prev/next, Home- and End-keys to select first/last.
|
|
|
88 |
Use the return key to apply the double-click-action to the current selection.
|
|
|
89 |
Also, alphabetic keys will select the next entry starting with that key.
|
|
|
90 |
|
|
|
91 |
The keyboard behavior can be further controlled with the keyActionStyle
|
|
|
92 |
instance variable (see SelectionInListView>>keyActionStyle:).
|
|
|
93 |
|
|
59
|
94 |
Finally, ignoreReselect controls if pressing on an already selected item
|
|
|
95 |
triggers the action or not. For some applications it is useful to allow
|
|
|
96 |
reselects (for example, the SystemBrowsers method-list updates the
|
|
|
97 |
source code in this case).
