a View for (string-)lists. |
46 |
||
47 |
This class can only passively display collections of strings- |
|
48 |
selections, editing, cursors etc. must be done in subclasses. |
|
49 |
see SelectionInListView, TextView etc. |
|
50 |
||
51 |
This code currently handles only fixed-height fonts correctly - |
|
52 |
should be rewritten in some places ... |
|
0 | 53 |
|
38 | 54 |
It can only scroll by full lines vertically (i.e. setting firstLineShown to ~~ 1) |
55 |
which should be changed to have this behavior optionally for smooth scroll. |
|
56 |
||
120 | 57 |
The text is internally kept in the list instance variable, and is supposed to consist |
58 |
of a collection (Ordered- or StringCollection) of line entries. |
|
59 |
Typically, individual entries are either strings or nil (for empty lines). |
|
60 |
However, any object which supports the displayOn: and widthIn: protocol can be |
|
61 |
used - see MultipleColumnListEntry as an example. |
|
62 |
Therefore, ListView (and all subclasses) are prepared to handle non-string entries |
|
63 |
(especially: attributed Text). |
|
64 |
||
65 |
The internal version of the text has tabulators expanded to blanks - when text is exchanged |
|
66 |
with an external medium (i.e. reading/writing files), these are expanded/compressed assuming |
|
67 |
a tab-setting of 8. This is done independent of the users tab setting, which is used |
|
68 |
while the text is edited. Thus, even if the tab setting is multiple of 4's, tabs are |
|
69 |
written in multiples of 8 when the text is saved. Since this is the default on all ascii |
|
70 |
terminals and printers, this assures that the text looks correctly indented when finally printed. |
|
71 |
||
305 | 72 |
Notice: |
73 |
||
74 |
ListView is one of the oldest widget classes in the current system and |
|
75 |
definitely requires some rewrite: |
|
76 |
||
120 | 77 |
Due to historic reasons (ListView implemented scrolling before the general |
78 |
scrolling code in View was added), this one does scrolling different from all other |
|
79 |
views. The general scrolling code (in View) uses the transformation for transparent scrolling. |
|
80 |
Here, the transformation is not used, instead it is done again, by keeping the firstLineShown |
|
81 |
(i.e. vertical offset) and leftOffset (horizontal offset). |
|
82 |
The most annoying consequence of this is, that scrolling is done by lines here, |
|
83 |
while its done in pixels in the View class. Thus, be careful, when changing things |
|
84 |
(better: dont touch it ;-) |
|
85 |
||
305 | 86 |
Also, all controller functionality is completely performed by the listView |
87 |
(and subclasses) itself. It is still possible, to define and set a specialized |
|
88 |
controller, though. I.e. if you like to change the input behavior, define |
|
89 |
a corresponding controller class and intersect the keyXXX/buttonXXX messages |
|
90 |
there. |
|
91 |
||
92 |
This will be totally rewritten ... so dont depend on the internals; especially the scrolling |
|
120 | 93 |
code will be totally removed here and the inherited functionality be used in the next version. |
