In some places the objj_msgSend function is called directly. Most of the times the old slower version is called. This commit will use the never faster version instead.

@class CPOutlineView

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.

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.
|
|
|
|
@section required 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.
|
|
@code - (id)outlineView:(CPOutlineView)outlineView child:(CPInteger)index ofItem:(id)item; @endcode
|
|
|
|
Returns YES if the item is expandable, otherwise NO.
|
|
@code - (BOOL)outlineView:(CPOutlineView)outlineView isItemExpandable:(id)item; @endcode
|
|
|
|
Returns the number of child items of a given item. If item is nil you should return the number of top level (root) items.
|
|
@code - (int)outlineView:(CPOutlineView)outlineView numberOfChildrenOfItem:(id)item; @endcode
|
|
|
|
Returns the object value of the item in a given column.
|
|
@code - (id)outlineView:(CPOutlineView)outlineView objectValueForTableColumn:(CPTableColumn)tableColumn byItem:(id)item; @endcode
|
|
|
|
---------
|
|
|
|
@section optional The following methods are optional:
|
|
|
|
@section editin Editing:
|
|
Sets the data object value for an item in a given column. This needs to be implemented if you want inline editing support.
|
|
@code - (void)outlineView:(CPOutlineView)outlineView setObjectValue:(id)object forTableColumn:(CPTableColumn)tableColumn byItem:(id)item; @endcode
|
|
|
|
|
|
@section sorting Sorting:
|
|
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
|
|
@code - (void)outlineView:(CPOutlineView)outlineView sortDescriptorsDidChange:(CPArray)oldDescriptors; @endcode
|
|
|
|
@section draganddrop Drag and Drop:
|
|
@note 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 @endnote
|
|
|
|
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.
|
|
@code - (BOOL)outlineView:(CPOutlineView)outlineView acceptDrop:(id < CPDraggingInfo >)info item:(id)item childIndex:(CPInteger)index; @endcode
|
|
|
|
|
|
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 <pre>-(void)setDropItem:(id)anItem dropChildIndex:(int)anIndex;</pre>
|
|
@code - (CPDragOperation)outlineView:(CPOutlineView)outlineView validateDrop:(id < CPDraggingInfo >)info proposedItem:(id)item proposedChildIndex:(CPInteger)index; @endcode
|
|
|
|
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.
|
|
@code - (BOOL)outlineView:(CPOutlineView)outlineView writeItems:(CPArray)items toPasteboard:(CPPasteboard)pboard; @endcode
