ImplementsListModel<T>, MultipleSelectionListModel<T>
Known subtypesContactsModel
Default implementation of the list model based on a List of elements.
The list model is an observable set of objects that com.codename1.ui.List uses to pull
the data to display.

Method details
getItemAt
public T getItemAt(int index)Returns the item at the given offset
Parameters
indexint- an index into this list
Returns
the item at the specified index
getSize
public int getSize()Returns the number of items in the list
Returns
the number of items in the list
getSelectedIndex
public int getSelectedIndex()Returns the selected list offset
Returns
the selected list index
setSelectedIndex
public void setSelectedIndex(int index)Sets the selected list offset can be set to -1 to clear selection
Parameters
indexint- an index into this list
addItem
public void addItem(T item)Adds the specified item to the end of this list.
An optional operation for mutable lists, it can throw an unsupported operation
exception if a list model is not mutable.
Parameters
itemT- the item to be added
setItem
public void setItem(int index, T item)Change the item at the given index
Parameters
indexint- the offset for the item
itemT- the value to set
addItemAtIndex
public void addItemAtIndex(T item, int index)Adding an item to list at given index
Parameters
itemT- the item to add
indexint- the index position in the list
removeItem
public void removeItem(int index)Removes the item at the specified position in this list.
Parameters
indexint- the index of the item to removed
removeAll
public void removeAll()Removes all elements from the model
addDataChangedListener
public void addDataChangedListener(DataChangedListener l)Invoked to indicate interest in future change events
Parameters
lDataChangedListener- a data changed listener
removeDataChangedListener
public void removeDataChangedListener(DataChangedListener l)Invoked to indicate no further interest in future change events
Parameters
lDataChangedListener- a data changed listener
fireDataChangedEvent
protected void fireDataChangedEvent(int status, int index)Broadcast a change event to all listeners
Parameters
statusint- the status of the event
indexint- the index changed
addSelectionListener
public void addSelectionListener(SelectionListener l)Invoked to indicate interest in future selection events
Parameters
lSelectionListener- a selection listener
removeSelectionListener
public void removeSelectionListener(SelectionListener l)Invoked to indicate no further interest in future selection events
Parameters
lSelectionListener- a selection listener
getList
public List<T> getList()Returns the internal list of items which makes traversal using iterators easier.
Returns
the list, notice that you shouldn’t modify it
addSelectedIndices
public void addSelectedIndices(int... indices)Adds indices to set of selected indices.
Parameters
indicesint...- Indices to add to selected indices.
removeSelectedIndices
public void removeSelectedIndices(int... indices)Removes indices from the set of selected indices.
Parameters
indicesint...- Indices to remove from selected indices.
getSelectedIndices
public int[] getSelectedIndices()Gets the selected indices in this model. Indices should be returned
in increasing order with no duplicates.
Returns
Selected indices in increasing order with no duplicates. If there
are no selected indices, then this will return a zero-length array.
setSelectedIndices
public void setSelectedIndices(int... indices)For use with multi-selection mode. Sets the selected indices in this model.
Note: This may fire multiple selectionChange events. For each “deselected” index, it will fire an event with the (oldIndex, newIndex) being (index, -1) (i.e. selected index changes from the index to -1. And for each newly selected index, it will fire the event with (oldIndex, newIndex) being (-1, index).
Parameters
indicesint...- The indices to select.
Throws
IllegalArgumentException- If
#isMultiSelectionMode()is false, and indices length is greater than 1.
isMultiSelectionMode
public boolean isMultiSelectionMode()Checks to see if this list model is in multi-selection mode.
Returns
the multiSelectionMode
setMultiSelectionMode
public void setMultiSelectionMode(boolean multiSelectionMode)Enables or disables multi-selection mode.
Parameters
multiSelectionModeboolean- the multiSelectionMode to set
