an editable text-field. Realized by using an EditTextView,
|
|
|
57 |
and forcing its size to 1 line - disabling cursor movement
|
|
|
58 |
in the vertical direction.
|
|
|
59 |
An action (leaveAction) is performed when the field is left
|
|
|
60 |
by either Return or a cursor movement, or if 'accept' is
|
|
|
61 |
performed from the menu.
|
|
121
|
62 |
|
|
|
63 |
Instance variables:
|
|
|
64 |
|
|
|
65 |
leaveAction <Block | nil> if non-nil, this is evaluated with
|
|
|
66 |
the key (#Return, #CursorUp etc.) when
|
|
|
67 |
the field is left via keyboard keys.
|
|
|
68 |
(fieldGroups use this to decide which
|
|
|
69 |
field has to be enabled next)
|
|
|
70 |
|
|
|
71 |
enabled <Boolean> if false, input is ignored.

|
|
|
78 |
a #accept then)
|
|
|
79 |
|
|
|
80 |
tabAction <Block | nil> if non-nil, keyboard input of a tab character
|
|
|
81 |
is not entered into the text, instead this block
|
|
|
82 |
is evaluated.
|
|
|
83 |
|
|
|
84 |
converter <PrintConverter | nil> if non-nil, this is supposed to convert between
|
|
|
