## Detailed Description

A widget for selecting and arranging actions/objects.

This widget allows the user to select from a set of objects and arrange the order of the selected ones using two list boxes labeled "Available" and "Used" with horizontal arrows in between to move selected objects between the two, and vertical arrows on the right to arrange the order of the selected objects.

The widget moves objects to the other listbox when doubleclicked if the property moveOnDoubleClick is set to true (default). See moveOnDoubleClick() and setMoveOnDoubleClick().

The user control the widget using the keyboard if enabled (default), see keyboardEnabled.

Note that this may conflist with keyboard selection in the selected list box, if you set that to anything else than QListBox::Single (which is the default).

To use it, simply construct an instance and then add items to the two listboxes, available through lbAvailable() and lbSelected(). Whenever you want, you can retrieve the selected options using QListBox methods on lbSelected().

This way, you can use your own QListBoxItem class, allowing you to easily store object data in those.

When an item is moved to a listbox, it is placed below the current item of that listbox.

Standard arrow icons are used, but you can use icons of your own choice if desired, see setButtonIcon(). It is also possible to set tooltips and whatsthis help for the buttons. See setButtonTooltip() and setButtonWhatsThis().

To set whatsthis or tooltips for the listboxes, access them through availableListbox() and selectedListBox().

All the moving buttons are automatically set enabled as expected.

Signals are sent each time an item is moved, allowing you to follow the users actions if you need to. See addedToSelection(), removedFromSelection(), movedUp() and movedDown()

## Member Enumeration Documentation

enum KActionSelector::MoveButton

| This enum indentifies the moving buttons. Definition at line 108 of file kactionselector.h.

enum KActionSelector::ButtonIconSize

| This enum identifies the icon sizes, used for the move buttons. The values correspond to the following pixel sizes: SmallIcon - the return value of IconSize( KIcon::Small ), the user defined size of a small icon in KDE. This is the default setting. Small - 16px Medium - 22px Large - 32px XLarge - 48px Definition at line 125 of file kactionselector.h.

enum KActionSelector::InsertionPolicy

| This enum defines policies for where to insert moved items in a listbox. The following policies are currently defined: BelowCurrent - The item is inserted below the listbox' currentItem() or at the end if there is no curent item. Sorted - The listbox is sort()ed after one or more items are inserted. AtTop - The item is inserted at index 0 in the listbox. AtBottom - The item is inserted at the end of the listbox. See also: availableInsertionPolicy(), setAvailableInsertionPolicy(), selectedInsertionPolicy(), setSelectedInsertionPolicy(). Definition at line 145 of file kactionselector.h.

## Member Function Documentation

QListBox * KActionSelector::availableListBox | ( |  | ) | const

| Returns: The QListBox holding the available actions Definition at line 128 of file kactionselector.cpp.

QListBox * KActionSelector::selectedListBox | ( |  | ) | const

| Returns: The QListBox holding the selected actions Definition at line 133 of file kactionselector.cpp.

bool KActionSelector::moveOnDoubleClick | ( |  | ) | const

| Returns: Wheather moveOnDoubleClcik is enabled. If enabled, an item in any listbox will be moved to the other one whenever doubleclicked. See also: setMoveOnDoubleClick()

void KActionSelector::setMoveOnDoubleClick | ( | bool | enable | ) |

| Sets moveOnDoubleClick to `enable`. See also: moveOnDoubleClick() Definition at line 244 of file kactionselector.cpp.

bool KActionSelector::keyboardEnabled | ( |  | ) | const

| Returns: Weather keyboard control is enabled. When Keyboard control is enabled, the widget will react to the following keyboard actions: CTRL + Right - simulate clicking the add button CTRL + Left - simulate clicking the remove button CTRL + Up - simulate clicking the up button CTRL + Down - simulate clicking the down button Additionally, pressing RETURN or ENTER on one of the list boxes will cause the current item of that listbox to be moved to the other listbox. The keyboard actions are enabled by default. See also: setKeyboardEnabled()

void KActionSelector::setKeyboardEnabled | ( | bool | enable | ) |

| Sets the keyboard enabled depending on `enable`. See also: keyboardEnabled() Definition at line 254 of file kactionselector.cpp.

QString KActionSelector::availableLabel | ( |  | ) | const

| Returns: The text of the label for the available items listbox.

void KActionSelector::setAvailableLabel | ( | const QString & | text | ) |

| Sets the label for the available items listbox to `text`. Note that this label has the listbox as its buddy, so that if you have a single ampersand in the text, the following character will become the accellerator to focus te listbox. Definition at line 264 of file kactionselector.cpp.

QString KActionSelector::selectedLabel | ( |  | ) | const

| Returns: the label of the selected items listbox.

void KActionSelector::setSelectedLabel | ( | const QString & | text | ) |

| Sets the label for the selected items listbox to `text`. Note that this label has the listbox as its buddy, so that if you have a single ampersand in the text, the following character will become the accellerator to focus te listbox. Definition at line 274 of file kactionselector.cpp.

ButtonIconSize KActionSelector::buttonIconSize | ( |  | ) | const

| Returns: the current ButtonIconSize.

void KActionSelector::setButtonIconSize | ( | ButtonIconSize | size | ) |

| Sets the button icon size. See ButtonIconSize for the possible values and their pixel meaning. Definition at line 284 of file kactionselector.cpp.

InsertionPolicy KActionSelector::availableInsertionPolicy | ( |  | ) | const

| Returns: The current insertion policy for the available listbox. The default policy for the available listbox is Sorted. See also InsertionPolicy, setAvailableInsertionPolicy().

void KActionSelector::setAvailableInsertionPolicy | ( | InsertionPolicy | policy | ) |

| Sets the insertion policy for the available listbox. See also InsertionPolicy, availableInsertionPolicy(). Definition at line 296 of file kactionselector.cpp.

InsertionPolicy KActionSelector::selectedInsertionPolicy | ( |  | ) | const

| Returns: The current insertion policy for the selected listbox. The default policy for the selected listbox is BelowCurrent. See also InsertionPolicy, setSelectedInsertionPolicy().

void KActionSelector::setButtonIconSet | ( | const QIconSet & | iconset,
|  | MoveButton | button
