## Enum DropMode

- java.lang.Object
- - java.lang.Enum<DropMode>
  - - javax.swing.DropMode

- All Implemented Interfaces:
    Serializable, Comparable<DropMode>

      public enum DropMode
      extends Enum<DropMode>

  Drop modes, used to determine the method by which a component tracks and indicates a drop location during drag and drop.
  Since:
    1.6

    Enum Constants
    Enum Constant and 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.

    - #### 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 Detail

    - #### values

          public static DropMode[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (DropMode c : DropMode.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static DropMode valueOf(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name
        `NullPointerException` - if the argument is null
