public Radiogroup getRadiogroup()
Radiogroup
that this radio button belongs to.
It is the nearest ancestor Radiogroup
.
In other words, it searches up the parent, parent's parent
and so on for any Radiogroup
instance.
If found this radio belongs the found radiogroup.
If not, this radio itself is a group.
public Radiogroup getRadiogroupApi()
Radiogroup
that this radio button belongs to.
It is the nearest ancestor Radiogroup
.
In other words, it searches up the parent, parent's parent
and so on for any Radiogroup
instance.
If found this radio belongs the found radiogroup.
If not, this radio itself is a group.

public boolean isSelected()
Default: false.
Don't override this. Override Checkbox.isChecked()
instead.
public void setSelected(boolean selected)
Don't override this. Override setChecked(boolean)
instead.
The same as setChecked(boolean)
.

Don't use this method if your application is purely based on ZK's event-driven model.
It is readonly, and it is generated automatically
to be the same as its parent's name (Radiogroup.getName()
).

Note: Component.setParent(org.zkoss.zk.ui.Component)
always calls back Component.insertBefore(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component)
and/or Component.removeChild(org.zkoss.zk.ui.Component)
,
while Component.insertBefore(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component)
and Component.removeChild(org.zkoss.zk.ui.Component)
always calls back Component.setParent(org.zkoss.zk.ui.Component)
,
if the parent is changed. Thus, you don't need to override
both Component.insertBefore(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component)
and Component.setParent(org.zkoss.zk.ui.Component)
, if you want
to customize the behavior.
