Gdk.Display.map_keyval

### Method

# Gdk Displaymap_keyval

#### Declaration [src]

    gboolean
    gdk_display_map_keyval (
      GdkDisplay* display,
      guint keyval,
      GdkKeymapKey** keys,
      int* n_keys
    )

#### Description [src]

Obtains a list of keycode/group/level combinations that will generate `keyval`.

Groups and levels are two kinds of keyboard mode; in general, the level determines whether the top or bottom symbol on a key is used, and the group determines whether the left or right symbol is used.

On US keyboards, the shift key changes the keyboard level, and there are no groups. A group switch key might convert a keyboard between Hebrew to English modes, for example.

`GdkEventKey` contains a %group field that indicates the active keyboard group. The level is computed from the modifier mask.

The returned array should be freed with g_free().

#### Parameters

`keyval`

  Type: `guint`

  A keyval, such as %GDK_KEY_a, %GDK_KEY_Up, %GDK_KEY_Return, etc.

`keys`

  Type: An array of `GdkKeymapKey*`

  Return location for an array of `GdkKeymapKey`.

  The argument will be set by the function.
  The length of the array is specified in the `n_keys` argument.
  The caller of the method takes ownership of the returned data, and is responsible for freeing it.

`n_keys`

  Type: `int*`

  Return location for number of elements in returned array.

  The argument will be set by the function.

#### Return value

Type: `gboolean`

`TRUE` if keys were found and returned.
