- ## Enum Constant Summary

  Enum Constants
  Enum Constant
  Description
  `INSERT`
  The drop location should be tracked in terms of the position where new data should be inserted.
  `INSERT_COLS`
  The drop location should be tracked in terms of the column index where new columns should be inserted to accommodate the dropped data.
  `INSERT_ROWS`
  The drop location should be tracked in terms of the row index where new rows should be inserted to accommodate the dropped data.
  `ON`
  The drop location should be tracked in terms of the index of existing items.
  `ON_OR_INSERT`
  This mode is a combination of `ON` and `INSERT`, specifying that data can be dropped on existing items, or in insert locations as specified by `INSERT`.
  `ON_OR_INSERT_COLS`
  This mode is a combination of `ON` and `INSERT_COLS`, specifying that data can be dropped on existing items, or as insert columns as specified by `INSERT_COLS`.
  `ON_OR_INSERT_ROWS`
  This mode is a combination of `ON` and `INSERT_ROWS`, specifying that data can be dropped on existing items, or as insert rows as specified by `INSERT_ROWS`.
  `USE_SELECTION`
  A component's own internal selection mechanism (or caret for text components) should be used to track the drop location.

- ## Enum Constant Details

  - ### USE_SELECTION

    public static final DropMode USE_SELECTION
    A component's own internal selection mechanism (or caret for text components) should be used to track the drop location.

  - ### ON

    public static final DropMode ON
    The drop location should be tracked in terms of the index of existing items. Useful for dropping on items in tables, lists, and trees.

  - ### INSERT

    public static final DropMode INSERT
    The drop location should be tracked in terms of the position where new data should be inserted. For components that manage a list of items (list and tree for example), the drop location should indicate the index where new data should be inserted. For text components the location should represent a position between characters. For components that manage tabular data (table for example), the drop location should indicate where to insert new rows, columns, or both, to accommodate the dropped data.

  - ### INSERT_ROWS

    public static final DropMode INSERT_ROWS
    The drop location should be tracked in terms of the row index where new rows should be inserted to accommodate the dropped data. This is useful for components that manage tabular data.

  - ### INSERT_COLS

    public static final DropMode INSERT_COLS
    The drop location should be tracked in terms of the column index where new columns should be inserted to accommodate the dropped data. This is useful for components that manage tabular data.

  - ### ON_OR_INSERT

    public static final DropMode ON_OR_INSERT
    This mode is a combination of `ON` and `INSERT`, specifying that data can be dropped on existing items, or in insert locations as specified by `INSERT`.

  - ### ON_OR_INSERT_ROWS

    public static final DropMode ON_OR_INSERT_ROWS
    This mode is a combination of `ON` and `INSERT_ROWS`, specifying that data can be dropped on existing items, or as insert rows as specified by `INSERT_ROWS`.

  - ### ON_OR_INSERT_COLS

    public static final DropMode ON_OR_INSERT_COLS
    This mode is a combination of `ON` and `INSERT_COLS`, specifying that data can be dropped on existing items, or as insert columns as specified by `INSERT_COLS`.

- ## Method Details

  - ### values

    public static DropMode[] values()
    Returns an array containing the constants of this enum class, in the order they are declared.
    Returns:
      an array containing the constants of this enum class, in the order they are declared

  - ### valueOf

    public static DropMode valueOf(String name)
    Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
    Parameters:
      `name` - the name of the enum constant to be returned.
    Returns:
      the enum constant with the specified name
    Throws:
      `IllegalArgumentException` - if this enum class has no constant with the specified name
      `NullPointerException` - if the argument is null
