public G9ComboBoxModel(Object[] items)

Constructs a G9ComboBoxModel object initialized with an array of objects.

Parameters:

items - an array of Object objects

Parameters:

v - a Vector object

Method Detail

addElement

public void addElement(Object anObject)

If this is a sorted combo box, and the added object is not null, and the added object is first in the sorted sequence, the added item is selected. If the specified object equals an object already present in the list, it is put just before the element in the list.

Specified by:

addElement in interface MutableComboBoxModel

Overrides:

addElement in class DefaultComboBoxModel

addElements

public void addElements(Collection<? extends Object> items)

Adds a collection of elements to the combo box model.

Parameters:

items - the collection of items to add.

isSorted

public boolean isSorted()

Returns the isSorted property

Returns:

true if elements in this combo are sorted.

setSorted

public void setSorted(boolean isSorted)

Sets the isSorted property. If set to true the elements in this combo is sorted.

Parameters:

compare

public int compare(Object o1,
                   Object o2)

Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

Note that null is considered the smalles possible value. The comparison is done by TypeTool.compareTo(Object, Object), ensuring a locale dependent comparison of Strings. Enumerations are compared using the title.

Specified by:

compare in interface Comparator<Object>

Parameters:

o1 - the first object to be compared

o2 - the second object to be compared

Returns:

a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

removeAllElements

Overrides:

removeAllElements in class DefaultComboBoxModel

removeElement

public void removeElement(Object anObject)

Specified by:

removeElement in interface MutableComboBoxModel

Overrides:

removeElement in class DefaultComboBoxModel

removeElementAt

public void removeElementAt(int index)

Specified by:

removeElementAt in interface MutableComboBoxModel

Overrides:

removeElementAt in class DefaultComboBoxModel
