Basically, an editField is an editor for a single line text, |

accepting: |
58 |
The opposite way to use editFields is to connect them to a model |
|
59 |
and let the field notify changes to it. |
|
60 |
This notification is called ``accepting''. |
|
61 |
Unless accepted, the models value is not updated from the editFields contents |
|
62 |
this default is the normal operation and way things should work, since most |
|
63 |
uses of editFields are not interested in every individual change |
|
64 |
(i.e. getting each keyStroke when a long number is entered). |
|
65 |
The default behavior is to ``accept'' when either return or a cursorUp/Down |
|
66 |
key is pressed in a field. |
|
67 |
However, the field can setup to accept/not accept on leave, on return |
|
68 |
or on each individual key input. |
|
69 |
See the methods #acceptOnLeave: / #acceptOnReturn: / #immediateAccept. |
|
70 |
||
71 |
In addition, the set of keys which are considered ``leaveKeys'' can be |
|
72 |
specified by #leaveKeys: (in case you need keys other than Return, CursorUp/Down). |
|
73 |
||
74 |
models value vs. field contents: |
|
75 |
Although the field internally keeps its contents as some string object, |
|
76 |
the application may prefer to think of numbers, floats, yes/no values etc. |
|
77 |
To support this, a converter may defined, which is responsible for conversion of |
|
78 |
strings to/from the models domain value. |
|
79 |
If present (i.e. nonNil), the converter is asked to convert a string to the models |
|
80 |
domain with #readValueFrom:aString and vice versa, a value to a string by #printStringFor:. |
|
81 |
The PrintConverter class already provides a number of standard conversions, see the examples. |
|
82 |
To access a converted value directly (i.e. not via the model), use #editValue. |
|
83 |
||
84 |
grouping: |
|
85 |
Individual fields do not know about being included in a group. This must be arranged on the |
|
86 |
outside, by placing multiple fields into an EnterFieldGroup. |
|
87 |
This groupObject keeps a reference to one active field, and forwards input from any other |
|
88 |
field to the active one. Also have a look at the examples for this. |
|
89 |
||
90 |
input completion: |
|
91 |
To support input completion (i.e. filename completion, classname completion etc.), |
|
92 |
a completionBlock can be defined which (if non-nil) is evaluated when the completion-key |
|
93 |
is pressed and its value is taken as the new field-contents. |
|
94 |
The physical completion-key is the Tab key (this one cannot be defined by |
|
95 |
the keyboardTranslation mechanism, since that would disable the Tab-key on regular text views. |
