DropMode (Java SE 19 & JDK 19) (original) (raw)

All Implemented Interfaces:

[Serializable](../../../java.base/java/io/Serializable.html "interface in java.io"), [Comparable](../../../java.base/java/lang/Comparable.html "interface in java.lang")<[DropMode](DropMode.html "enum class in javax.swing")>, [Constable](../../../java.base/java/lang/constant/Constable.html "interface in java.lang.constant")

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
The drop location should be tracked in terms of the position where new data should be inserted.
The drop location should be tracked in terms of the column index where new columns should be inserted to accommodate the dropped data.
The drop location should be tracked in terms of the row index where new rows should be inserted to accommodate the dropped data.
The drop location should be tracked in terms of the index of existing items.
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.
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.
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.
A component's own internal selection mechanism (or caret for text components) should be used to track the drop location.

• Method Summary

Returns the enum constant of this class with the specified name.
[values](#values%28%29)()
Returns an array containing the constants of this enum class, in the order they are declared.

• 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

  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

  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](../../../java.base/java/lang/IllegalArgumentException.html "class in java.lang") - if this enum class has no constant with the specified name
  [NullPointerException](../../../java.base/java/lang/NullPointerException.html "class in java.lang") - if the argument is null
