Field Detail

_text

protected java.lang.String _text

The string label that is shown in the list.

_isTextEnabled

protected boolean _isTextEnabled

This should be true if the list's text is drawn as enabled; false otherwise.

_isTextSelectable

protected boolean _isTextSelectable

This should be true if the list's text is selectable; false otherwise. Usually, you should allow the text to be selected even if the label itself is disabled. This at least lets the user know that the selection is acknowledged, but no action is permitted.

_icon

protected javax.swing.Icon _icon

The icon shown with the text. If null, no icon is shown.

_hasCheckBox

protected boolean _hasCheckBox

If true, then the cell renderer should include a checkbox; if false then no checkbox. The checkbox is a a tri-state checkbox. To set the checkbox to the third state call setCheckBoxState(null).

_checkBoxState

protected TriStateBoolean _checkBoxState

If there is a check box, this variable reports its state. If no checkbox, then this variable's value is undefined.

_isCheckBoxEnabled

protected boolean _isCheckBoxEnabled

This should be true if the list's checkbox should have a visual appearance of being enabled.

_isCheckBoxSelectable

protected boolean _isCheckBoxSelectable

This should be true if the list's checkbox is selectable (i.e. if it can be toggled). If false, any attempt to change the checkbox should be ignored.

_isArmed

protected boolean _isArmed

If true, indicates that the check box is partially committed.

_isPressed

protected boolean _isPressed

If true, indicates that the check box should be rendered as being pressed down.

_userObject

protected java.lang.Object _userObject

Can be used to hold additional user information.

_toolTipText

protected java.lang.String _toolTipText

The tooltip to show in the list

_heightAdj

protected int _heightAdj

copyTo

public java.lang.Object copyTo(java.lang.Object target)

Description copied from interface: Copyable

Copies the internal state of this object to the specified copy. If copy is null, then this method should create a new instance of this class and proceed to copy the internal state to the newly created object. Generally, only the persistent state of the object should be copied, but whether or not it is appropriate to copy transient properties is at the discretion of the individual implementor.

Regardless of whether the copy occurs to an existing object or to a newly created object, the return value is object to which this object's state was copied.

There is a standard implementation pattern for the copyTo method that helps avoid problems that arise when a Copyable object is subclassed. The pattern is:

    public Object copyTo( Object target )
    {
      final <this_class> copy =
        target != null ? (<this_class>) target : new <this_class>();
      copyToImpl( copy );
      return copy;
    }

    protected final void copyToImpl( <this_class> copy )
    {
      super.copyToImpl( copy );  //  if necessary
      //  put code here for copying the properties of <this_class>
    }
  

The parameter passed into the copyToImpl method is the same type of this class. The responsibility of copyToImpl is to copy the state of this class through direct access of the fields. The copyToImpl method should not use getters and setters since these may be overridden, causing the state of this class to be incompletely copied.

Specified by:

copyTo in interface Copyable

Parameters:

target - The target object to which the state of this object should be copied. If target is null, then the copyTo method will return a new instance of this class.

Returns:

The object to which the state of this object was copied. If the target was non-null, then the return value is the same as the target object that was passed in; otherwise, the return value is a new instance of this class.

copyToImpl

protected final void copyToImpl(CheckBoxListCellData copy)

setGroupId

public void setGroupId(java.lang.Object groupId)

getGroupId

public java.lang.Object getGroupId()

isGroupTitle

public boolean isGroupTitle()

setGroupTitle

public void setGroupTitle(boolean groupTitle)
