org.itsnat.comp .ItsNatList

ItsNatList

public interface ItsNatList extends ItsNatElementComponent(Code)

Is the base interface of list based components.

A generic list component manages a javax.swing.ListModel data list, item values are rendered as markup using a special object, the renderer, and may be optionally edited "in place" using a user defined editor.

Any change to the data model is notified to the component and the markup is rendered again. The data model ever mandates over the markup, any initial markup content (initial child elements) is removed.

This component family is the "componentized" version of org.itsnat.core.domutil.ElementList and follows a similar philosophy.

Method Summary
public ListModel	createDefaultListModel() Creates a data model instance appropriated to this component.
public int	getEditingIndex() Returns the index of the list item being edited. the index of the list item being edited.
public String	getEditorActivatorEvent() Returns the event type used to activate the list item edition process by the user. the event type used to activate the edition.
public ItsNatListCellEditor	getItsNatListCellEditor() Returns the current list item editor.
public ItsNatListCellRenderer	getItsNatListCellRenderer() Returns the current component renderer.
public ItsNatListStructure	getItsNatListStructure() Returns the component structure.
public ItsNatListUI	getItsNatListUI() Returns the user interface manager of this component.
public ListModel	getListModel() Returns the current data model of this component.
public int	getSelectedIndex() Returns the index of the first selected list item.
public int	indexOf(Object obj) Returns the zero based position in the list of the specified value. If the value is repeated returns the first position. Parameters: obj - the object value to search.
public boolean	isEditing() Informs whether a list item value is being edited.
public void	setEditorActivatorEvent(String eventType) Sets the event type used to activate the list item edition process by the user.
public void	setItsNatListCellEditor(ItsNatListCellEditor editor) Sets the list item editor. List item edition works very much the same as label edition (see ItsNatLabel.setItsNatLabelEditor(ItsNatLabelEditor) ). Some differences: The edition process starts programmatically by calling ItsNatList.startEditingAt(int) . The edition takes place inside the list item content element as returned by ItsNatListStructure.getContentElement(ItsNatListintorg.w3c.dom.Element) . The new item value is set to the data model calling `javax.swing.DefaultListModel.setElementAt(Object,int)`, if the data model is not `DefaultListModel` is the programmer responsibility to set the new value to the data model (detecting when the editor stops editing, see `javax.swing.CellEditor.addCellEditorListener(javax.swing.event.CellEditorListener)`). Parameters: editor - the new editor.
public void	setItsNatListCellRenderer(ItsNatListCellRenderer renderer) Sets the component renderer.
public void	setListModel(ListModel dataModel) Changes the data model of this component. Current data model is disconnected from this component, and the new data model is bound to this component, every change is tracked and updates the user interfaces accordingly. If the specified data model is the same instance as the current data model, then is reset, component listener is removed and added again.
public void	setSelectedIndex(int index) Selects the specified list item.
public void	startEditingAt(int index) Used to start programmatically a list item edition process "in place".

Method Detail

createDefaultListModel
public ListModel createDefaultListModel()(Code)
	Creates a data model instance appropriated to this component. This instance is not bound to the component. a new data model instance.

getEditingIndex
public int getEditingIndex()(Code)
	Returns the index of the list item being edited. the index of the list item being edited. -1 if none is being edited.

getEditorActivatorEvent
public String getEditorActivatorEvent()(Code)
	Returns the event type used to activate the list item edition process by the user. the event type used to activate the edition. By default is "dblclick". See Also: ItsNatList.setEditorActivatorEvent(String)

getItsNatListCellEditor
public ItsNatListCellEditor getItsNatListCellEditor()(Code)
	Returns the current list item editor. This object is used to edit in place a list item value. the current editor. By default uses the default editor calling (ItsNatComponentManager.createDefaultItsNatListCellEditor(ItsNatComponent)) with a null parameter. See Also: ItsNatList.setItsNatListCellEditor(ItsNatListCellEditor)

getItsNatListCellRenderer
public ItsNatListCellRenderer getItsNatListCellRenderer()(Code)
	Returns the current component renderer. This renderer converts a list item value to markup. the current renderer. By default uses the default renderer (ItsNatComponentManager.createDefaultItsNatListCellRenderer) See Also: ItsNatList.setItsNatListCellRenderer(ItsNatListCellRenderer)

getItsNatListStructure
public ItsNatListStructure getItsNatListStructure()(Code)
	Returns the component structure. the component structure.

getItsNatListUI
public ItsNatListUI getItsNatListUI()(Code)
	Returns the user interface manager of this component. the user interface manager.

getListModel
public ListModel getListModel()(Code)
	Returns the current data model of this component. the current data model See Also: ItsNatList.setListModel(javax.swing.ListModel)

getSelectedIndex
public int getSelectedIndex()(Code)
	Returns the index of the first selected list item. If the component allows multiple selection returns the first one. index of the first selected list item. -1 if none is selected.

indexOf
public int indexOf(Object obj)(Code)
	Returns the zero based position in the list of the specified value. If the value is repeated returns the first position. Parameters: obj - the object value to search. the zero based position of the value, -1 if not in the list.

isEditing
public boolean isEditing()(Code)
	Informs whether a list item value is being edited. true if a list item value is being edited. See Also: ItsNatList.startEditingAt(int)

setEditorActivatorEvent
public void setEditorActivatorEvent(String eventType)(Code)
	Sets the event type used to activate the list item edition process by the user. Parameters: eventType - the event type used to activate the edition. See Also: ItsNatList.getEditorActivatorEvent() See Also:

setItsNatListCellEditor

public void setItsNatListCellEditor(ItsNatListCellEditor editor)(Code)

Sets the list item editor.

List item edition works very much the same as label edition (see ItsNatLabel.setItsNatLabelEditor(ItsNatLabelEditor) ).

Some differences:

The edition process starts programmatically by calling ItsNatList.startEditingAt(int) .

The edition takes place inside the list item content element as returned by ItsNatListStructure.getContentElement(ItsNatListintorg.w3c.dom.Element) .

The new item value is set to the data model calling javax.swing.DefaultListModel.setElementAt(Object,int), if the data model is not DefaultListModel is the programmer responsibility to set the new value to the data model (detecting when the editor stops editing, see javax.swing.CellEditor.addCellEditorListener(javax.swing.event.CellEditorListener)).

Parameters:
editor - the new editor. May be null (edition disabled).
See Also: ItsNatList.getItsNatListCellEditor()

setItsNatListCellRenderer
public void setItsNatListCellRenderer(ItsNatListCellRenderer renderer)(Code)
	Sets the component renderer. Parameters: renderer - the new renderer. See Also: ItsNatList.getItsNatListCellRenderer() See Also:

setListModel

public void setListModel(ListModel dataModel)(Code)

Changes the data model of this component.

Current data model is disconnected from this component, and the new data model is bound to this component, every change is tracked and updates the user interfaces accordingly.

If the specified data model is the same instance as the current data model, then is reset, component listener is removed and added again. Use this technique if you want to add a data model listener to be executed before the default component listener.
Parameters:
dataModel - the new data model.
See Also: ItsNatList.getListModel()

setSelectedIndex
public void setSelectedIndex(int index)(Code)
	Selects the specified list item. If this component allows multiple selection, the current selection is cleared before. Parameters: index - the index of the item to select

startEditingAt
public void startEditingAt(int index)(Code)
	Used to start programmatically a list item edition process "in place". See Also: ItsNatList.isEditing()
