Methods in javax.swing.tree with parameters of type MutableTreeNode
Modifier and Type
Method
Description
`void`
DefaultMutableTreeNode.`add(MutableTreeNode newChild)`
Removes `newChild` from its parent and makes it a child of this node by adding it to the end of this node's child array.
`void`
DefaultMutableTreeNode.`insert(MutableTreeNode newChild, int childIndex)`
Removes `newChild` from its present parent (if it has a parent), sets the child's parent to this node, and then adds the child to this node's child array at index `childIndex`.
`void`
MutableTreeNode.`insert(MutableTreeNode child, int index)`
Adds `child` to the receiver at `index`.
`void`
DefaultTreeModel.`insertNodeInto(MutableTreeNode newChild, MutableTreeNode parent, int index)`
Invoked this to insert newChild at location index in parents children.
`void`
DefaultMutableTreeNode.`remove(MutableTreeNode aChild)`
Removes `aChild` from this node's child array, giving it a null parent.
`void`
MutableTreeNode.`remove(MutableTreeNode node)`
Removes `node` from the receiver.
`void`
DefaultTreeModel.`removeNodeFromParent(MutableTreeNode node)`
Message this to remove node from its parent.
`void`
DefaultMutableTreeNode.`setParent(MutableTreeNode newParent)`
Sets this node's parent to `newParent` but does not change the parent's child array.
`void`
MutableTreeNode.`setParent(MutableTreeNode newParent)`
Sets the parent of the receiver to `newParent`.
