A tree control presents information as a hierarchy, with items that may be expanded
|
1998-11-28 08:38:40 -05:00
|
|
|
to show further items. Items in a tree control are referenced by wxTreeItemId handles.
|
1998-05-20 10:25:30 -04:00
|
|
|
|
|
|
|
To intercept events from a tree control, use the event table macros described in \helpref{wxTreeEvent}{wxtreeevent}.

Returns the first child; call \helpref{wxTreeCtrl::GetNextChild}{wxtreectrlgetnextchild} for the next child.
|
|
|
|
|
|
|
|
For this enumeration function you must pass in a `cookie' parameter
|
|
|
|
which is opaque for the application but is necessary for the library
|
|
|
|
to make these functions reentrant (i.e. allow more than one
|
|
|
|
enumeration on one and the same object simultaneously). The cookie passed to
|
|
|
|
GetFirstChild and GetNextChild should be the same.
|
|
|
|
|
|
|
|
Returns 0 if there are no further children.

For this enumeration function you must pass in a `cookie' parameter

which is opaque for the application but is necessary for the library

to make these functions reentrant (i.e. allow more than one
|

|
enumeration on one and the same object simultaneously). The cookie passed to
|
|
|

GetFirstChild and GetNextChild should be the same.

|
|

|
|
|
wxTreeItemData is some (arbitrary) user class associated with some item. The
|
|
|
|
main advantage of having this class (compared to the old untyped interface) is
|
|
|
|
that wxTreeItemData's are destroyed automatically by the tree and, as this
|
|
|
|
class has virtual dtor, it means that the memory will be automatically
|
|
|
|
freed. We don't just use wxObject instead of wxTreeItemData because
|
|
|
|
the size of this class is critical: in any real application, each tree leaf
|
|
|
|
will have wxTreeItemData associated with it and number of leaves may be
|
|
|
|
quite big.
|
|
|
|
|
|
|
|
Because the objects of this class are deleted by the tree, they should
|
|
|
|
always be allocated on the heap.
