Constructor Detail

DefaultSelectable

public DefaultSelectable(java.lang.Object object)

Creates CheckBoxListElement with an actual object. In the case of CheckBoxList, instead of add the object directly to ListModel, you should wrap it in CheckBoxListElement and add CheckBoxListElement into ListModel.

Sets the actual element.

Parameters:

object -

isSelected

public boolean isSelected()

Gets the selected status.

Specified by:

isSelected in interface Selectable

Returns:

true if it is selected. Otherwise, false.

setEnabled

public void setEnabled(boolean enabled)

Enabled selection change. Enabled false doesn't mean selected is false. If it is selected before, setEnable(false) won't make selected become false. In the other word, setEnabled won't change the the value of isSelected().

Specified by:

setEnabled in interface Selectable

Parameters:

isEnabled

public boolean isEnabled()

Checks if selection change is allowed.

Specified by:

isEnabled in interface Selectable

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides to consider the toString() of object only. From outside point of view, this class should behave just like object itself. That's why we override toString.
