EnterFieldGroup controlls the interaction between EnterFields
|
|
|
26 |
enabling next/prev field when a field is left. Instances of
|
|
|
27 |
this class keep track of which field of the group is the currentField
|
|
|
28 |
(i.e. the one getting keyboard input).
|
|
|
29 |
The block accessable as leaveAction is evaluated when the last
|
|
|
30 |
field of the group is left (by cursor-down or cr). Usually this block
|
|
|
31 |
triggers some action on the fields.
