NAME

XkbResizeKeyType − Change the number of levels in a key type

SYNOPSIS

Status XkbResizeKeyType

(XkbDescPtr xkb, int type_ndx, int map_count,

Bool want_preserve, int new_num_lvls);

ARGUMENTS

− xkb

keyboard description containing client map to update

− type_ndx

index in xkb->map->types of type to change

− map_count

total # of map entries needed for the type

− want_preserve

True => list of preserved modifiers is necessary

− new_num_lvls

new max # of levels for type

DESCRIPTION

XkbResizeKeyType changes the type specified by xkb->map->types[type_ndx], and reallocates the symbols and actions bound to all keys that use the type, if necessary. XkbResizeKeyType updates only the local copy of the types in xkb; to update the server’s copy for the physical device, use XkbSetMap or XkbChangeMap after calling XkbResizeKeyType.

The map_count parameter specifies the total number of map entries needed for the type, and can be zero or greater. If map_count is zero, XkbResizeKeyType frees the existing map and preserve entries for the type if they exist and sets them to NULL.

The want_preserve parameter specifies whether a preserve list for the key should be created. If want_preserve is True, the preserve list with map_count entries is allocated or reallocated if it already exists. Otherwise, if want_preserve is False, the preserve field is freed if necessary and set to NULL.

The new_num_lvls parameter specifies the new maximum number of shift levels for the type and is used to calculate and resize the symbols and actions bound to all keys that use the type.

If type_ndx does not specify a legal type, new_num_lvls is less than 1, or the map_count is less than zero, XkbResizeKeyType returns BadValue. If XkbResizeKeyType encounters any problems with allocation, it returns BadAlloc. Otherwise, it returns Success.

RETURN VALUES

Success

The XkbResizeKeyType function returns Success if type_ndx specifies a legal type, new_num_lvls is greater than zero and map_count is positive.

DIAGNOSTICS

	BadAlloc		Unable to allocate storage
	BadValue		An argument is out of range
