Constructor Details

RmaJList

public RmaJList(Vector<? extends E> listData)

Construct a JList that displays the elements in the specified Vector.

RmaJList

public RmaJList()

Constructs a JList with an empty model.

RmaJList

public RmaJList(ListModel<E> dataModel)

Construct a JList that displays the elements in the specified, non-null model.

RmaJList

public RmaJList(E[] listData)

Construct a JList that displays the elements in the specified array.

Method Details

clearPerformed

public void clearPerformed()

Specified by:

clearPerformed in interface FormManagementListener

createKeyListener

protected KeyListener createKeyListener()

Creates the key listener for handling type-ahead. Returns an instance of BasicComboBoxUI$KeyHandler.

createDefaultKeySelectionManager

protected RmaJList.KeySelectionManager createDefaultKeySelectionManager()

Returns an instance of the default key-selection manager.

Returns:

the KeySelectionManager currently used by the list

selectWithKeyChar

public boolean selectWithKeyChar(char keyChar)

Selects the list item that correponds to the specified keyboard character and returns true, if there is an item corresponding to that character. Otherwise, returns false.

Parameters:

keyChar - a char, typically this is a keyboard key typed by the user

isNavigationKey

protected boolean isNavigationKey(int keyCode)

Returns whether or not the supplied keyCode maps to a key that is used for navigation. This is used for optimizing key input by only passing non- navigation keys to the type-ahead mechanism. Subclasses should override this if they change the navigation keys.

setIsEditable

public void setIsEditable(boolean b)

Specified by:

setIsEditable in interface EditableComponent

setModified

public void setModified(boolean b)

Specified by:

setModified in interface Modifiable

isModified

public boolean isModified()

Specified by:

isModified in interface Modifiable

getItemCount

public int getItemCount()

get the number of items in the List

Returns:

the number of items.

See Also:

• ListModel.getSize()

getValueAt

public E getValueAt(int idx)

get the Value in the list at index idx

Parameters:

idx - the index to get the value at

Returns:

the value at idx or null if idx isn't a valid index
