Detailed Description

CPOutlineView is a subclass of CPTableView that inherits the row and column format to display hierarchical data. The outlineview adds the ability to expand and collapse items. This is useful for browsing a tree like structure such as directories or a filesystem.

Like the tableview, an outlineview uses a data source to supply its data. For this reason you must implement a couple data source methods (documented in setDataSource:).

Theme states for custom data views are documented in CPTableView.

Definition at line 2 of file CPOutlineView.h.

Method Documentation

◆ addTableColumn:()

- (void) addTableColumn: (CPTableColumn aTableColumn

Adds a new table column to the receiver. If this is the first column added it will automatically be set to the outline column.

Also see -setOutlineTableColumn:.

This behavior deviates from cocoa slightly.
CPTableColumnaTableColumn - The table column to add.

Reimplemented from CPTableView.

Definition at line 1338 of file CPOutlineView.j.

Definition at line 422 of file CPOutlineView.j.

◆ setDataSource:()

- (void) setDataSource: (id <CPOutlineViewDataSource>)  aDataSource

In addition to standard delegation, the outline view also supports data source delegation. This method sets the data source object. Just like the TableView you have CPTableColumns but instead of rows you deal with items.

You must implement these data source methods:

Returns the child item at an index of a given item. if item is nil you should return the appropriate root item.

- (id)outlineView:(CPOutlineView)outlineView child:(CPInteger)index ofItem:(id)item;

Returns YES if the item is expandable, otherwise NO.

- (BOOL)outlineView:(CPOutlineView)outlineView isItemExpandable:(id)item;

Returns the number of child items of a given item. If item is nil you should return the number of top level (root) items.

- (int)outlineView:(CPOutlineView)outlineView numberOfChildrenOfItem:(id)item;

Returns the object value of the item in a given column.

- (id)outlineView:(CPOutlineView)outlineView objectValueForTableColumn:(CPTableColumn)tableColumn byItem:(id)item;

The following methods are optional:


Sets the data object value for an item in a given column. This needs to be implemented if you want inline editing support.

- (void)outlineView:(CPOutlineView)outlineView setObjectValue:(id)object forTableColumn:(CPTableColumn)tableColumn byItem:(id)item;


The outlineview will call this method if you click the table header. You should sort the datasource based off of the new sort descriptors and reload the data

- (void)outlineView:(CPOutlineView)outlineView sortDescriptorsDidChange:(CPArray)oldDescriptors;

Drag and Drop:

In order for the outlineview to receive drops don't forget to first register the tableview for drag types like you do with every other view

Return YES if the operation was successful otherwise return NO. The data source should incorporate the data from the dragging pasteboard in this method implementation. To get this data use the draggingPasteboard method on the CPDraggingInfo object.

- (BOOL)outlineView:(CPOutlineView)outlineView acceptDrop:(id < CPDraggingInfo >)info item:(id)item childIndex:(CPInteger)index;

Return the drag operation (move, copy, etc) that should be performed if a registered drag type is over the tableview The data source can retarget a drop if you want by calling

-(void)setDropItem:(id)anItem dropChildIndex:(int)anIndex;
- (CPDragOperation)outlineView:(CPOutlineView)outlineView validateDrop:(id < CPDraggingInfo >)info proposedItem:(id)item proposedChildIndex:(CPInteger)index;

Returns YES if the drop operation is allowed otherwise NO. This method is invoked by the outlineview after a drag should begin, but before it is started. If you don't want the drag to being return NO. If you want the drag to begin you should return YES and place the drag data on the pboard.

- (BOOL)outlineView:(CPOutlineView)outlineView writeItems:(CPArray)items toPasteboard:(CPPasteboard)pboard;

Definition at line 289 of file CPOutlineView.j.

◆ setDelegate:()

- (void) setDelegate: (id <CPOutlineViewDelegate>)  aDelegate

Sets the delegate for the outlineview.

The following methods can be implemented:

aDelegate- the delegate object you wish to set for the receiver.

User Interaction Notifications:

Called when the user moves a column in the outlineview.

- (void)outlineViewColumnDidMove:(CPNotification)notification;

Called when the user resizes a column in the outlineview.

- (void)outlineViewColumnDidResize:(CPNotification)notification;

Called when the user collapses an item in the outlineview.

- (void)outlineViewItemDidCollapse:(CPNotification)notification;

Called when the user expands an item in the outlineview.

- (void)outlineViewItemDidExpand:(CPNotification)notification;

Called when the user collapses an item in the outlineview, but before the item is actually collapsed.

- (void)outlineViewItemWillCollapse:(CPNotification)notification;

Called when the used expands an item, but before the item is actually expanded.

- (void)outlineViewItemWillExpand:(CPNotification)notification;

Called when the user changes the selection of the outlineview.

- (void)outlineViewSelectionDidChange:(CPNotification)notification;

Called when the user changes the selection of the outlineview, but before the change is made.

- (void)outlineViewSelectionIsChanging:(CPNotification)notification;

Expanding and collapsing items:

Return YES if the item should be given permission to expand, otherwise NO.

- (BOOL)outlineView:(CPOutlineView)outlineView shouldExpandItem:(id)item;

Return YES if the item should be given permission to collapse, otherwise NO.

- (BOOL)outlineView:(CPOutlineView)outlineView shouldCollapseItem:(id)item;


Return YES to allow the selection of tableColumn, otherwise NO.

- (BOOL)outlineView:(CPOutlineView)outlineView shouldSelectTableColumn:(CPTableColumn)tableColumn;

Return YES to allow the selection of an item, otherwise NO.

- (BOOL)outlineView:(CPOutlineView)outlineView shouldSelectItem:(id)item;

Return YES to allow the selection of the outlineview to be changed, otherwise NO.

- (BOOL)selectionShouldChangeInOutlineView:(CPOutlineView)outlineView;

Displaying DataViews:

Called when a dataView is about to be displayed. This gives you the ability to alter the dataView if needed.

- (void)outlineView:(CPOutlineView)outlineView willDisplayView:(id)dataView forTableColumn:(CPTableColumn)tableColumn item:(id)item;


Return YES to allow for editing of a dataview at given item and tableColumn, otherwise NO to prevent the edit.

- (BOOL)outlineView:(CPOutlineView)outlineView shouldEditTableColumn:(CPTableColumn)tableColumn item:(id)item;

Group Items:

Implement this to indicate whether a given item should be rendered using the group item style. Return YES if the item is a group item, otherwise NO.

- (BOOL)outlineView:(CPOutlineView)outlineView isGroupItem:(id)item;

Variable Item Heights

Implement this method to get custom heights of rows based on the item. This delegate method will be passed your 'item' object and expects you to return an integer height.

This should only be implemented if rows will be different heights, if you want to set a height for ALL of your rows see -setRowHeight:
- (int)outlineView:(CPOutlineView)outlineView heightOfRowByItem:(id)anItem;
