javax.swing.JTree$DropLocation
A subclass of TransferHandler.DropLocation representing a drop location for a JTree.
A subclass of TransferHandler.DropLocation representing a drop location for a JTree.
get-child-indexclj
(get-child-index this)Returns the index where the dropped data should be inserted with respect to the path returned by getPath().
For drop modes DropMode.USE_SELECTION and DropMode.ON, this index is unimportant (and it will always be -1) as the only interesting data is the path over which the drop operation occurred.
For drop mode DropMode.INSERT, this index indicates the index at which the data should be inserted into the parent path represented by getPath(). -1 indicates that the drop occurred over the parent itself, and in most cases should be treated as inserting into either the beginning or the end of the parent's list of children.
For DropMode.ON_OR_INSERT, this value will be an insert index, as described above, or -1 if the drop occurred over the path itself.
returns: the child index - int
Returns the index where the dropped data should be inserted with respect to the path returned by getPath(). For drop modes DropMode.USE_SELECTION and DropMode.ON, this index is unimportant (and it will always be -1) as the only interesting data is the path over which the drop operation occurred.

For DropMode.ON_OR_INSERT, this value will be an insert index, as described above, or -1 if the drop occurred over the path itself. returns: the child index - `int`
get-pathclj
(get-path this)Returns the path where dropped data should be placed in the tree.
Interpretation of this value depends on the drop mode set on the component. If the drop mode is DropMode.USE_SELECTION or DropMode.ON, the return value is the path in the tree over which the data has been (or will be) dropped. null indicates that the drop is over empty space, not associated with a particular path.
If the drop mode is DropMode.INSERT, the return value refers to the path that should become the parent of the new data, in which case getChildIndex() indicates where the new item should be inserted into this parent path. A null path indicates that no parent path has been determined, which can happen for multiple reasons:
The tree has no model
There is no root in the tree
The root is collapsed
The root is a leaf node
It is up to the developer to decide if and how they wish to handle the null case.
If the drop mode is DropMode.ON_OR_INSERT, getChildIndex can be used to determine whether the drop is on top of the path itself (-1) or the index at which it should be inserted into the path (values other than -1).

returns: the drop path - `javax.swing.tree.TreePath`to-stringclj
(to-string this)Returns a string representation of this drop location. This method is intended to be used for debugging purposes, and the content and format of the returned string may vary between implementations.
returns: a string representation of this drop location - java.lang.String
