Method Detail

nodeInserted

default void nodeInserted(TreeView treeView,
                          Sequence.Tree.Path path,
                          int index)

Called when a node has been inserted into the tree view.

Parameters:

treeView - The source of this event.

path - The path to the branch where the node was inserted.

index - The index of the newly inserted node within the branch.

nodesRemoved

default void nodesRemoved(TreeView treeView,
                          Sequence.Tree.Path path,
                          int index,
                          int count)

Called when nodes have been removed from the tree view.

Parameters:

treeView - The source of this event.

path - The path to the branch where the node(s) were removed.

index - The index to the first removed node within the branch.

count - The number of nodes that were removed, or -1 if all nodes were removed.

nodeUpdated

default void nodeUpdated(TreeView treeView,
                         Sequence.Tree.Path path,
                         int index)

Called when a node in the tree view has been updated.

Parameters:

treeView - The source of this event.

path - Path to the branch that is the parent of the updated node.

index - Index of the updated node within the branch.

nodesCleared

default void nodesCleared(TreeView treeView,
                          Sequence.Tree.Path path)

Called when the nodes in a branch have been cleared.

Parameters:

treeView - The source of this event.

path - Path to the branch where the nodes were cleared.

nodesSorted

default void nodesSorted(TreeView treeView,
                         Sequence.Tree.Path path)

Called when the nodes in a branch have been sorted.

Parameters:

treeView - The source of this event.

path - Path to the branch where the nodes were sorted.
