Create new ButtonGroup class that implements org.apache.pivot.collections.Group
and Iterable<Button>
----------------------------------------------------------------------------------------------------
Key: PIVOT-292
URL: https://issues.apache.org/jira/browse/PIVOT-292
Project: Pivot
Issue Type: Improvement
Components: wtk
Reporter: Greg Brown
Priority: Minor
Fix For: 1.3.1
Move Button.Group out into its own top-level class that implements
org.apache.pivot.collections.Group. Currently, there is no way to enumerate a
group's contents, and it seems like there should be (Swing's ButtonGroup class
does support this).
We'd end up with something along these lines:
ButtonGroup : Group, Iterable<Button> {
add(Button):void
remove(Button):boolean
getSelection():Button
setSelection(Button):void
}
ButtonGroupListener {
selectionChanged(previousSelection:Button):void
}
Button {
...
getGroup():ButtonGroup
setGroup(ButtonGroup):void
}
ButtonGroup#add() and remove() would call Button#setGroup(), and vice versa.
Similarly, ButtonGroup#setSelection() would call Button#setSelected(), and vice
versa. We'd also move the named group dictionary to ButtonGroup.
As part of this change, the existing Button.Group class would be deprecated and
slated for removal in Pivot 1.4.
