KActionSelector Class Reference

from PyKDE4.kdeui import *

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 QListWidget.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 QListWidget methods on lbSelected().

This way, you can use your own QListWidgetItem 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 availableListWidget() and selectedListWidget().

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()

movedDown	(	QListWidgetItem	item
	)

Emitted when an item is moved downwards in the "selected" listbox.

Signal syntax:: QObject.connect(source, SIGNAL("movedDown(QListWidgetItem*)"), target_slot)

movedUp	(	QListWidgetItem	item
	)

Emitted when an item is moved upwards in the "selected" listbox.

Signal syntax:: QObject.connect(source, SIGNAL("movedUp(QListWidgetItem*)"), target_slot)

Method Documentation

__init__	(	self,
		QWidget	parent=0
	)

__init__	(	self,
		KActionSelector	a0
	)

KActionSelector.InsertionPolicy availableInsertionPolicy ( self )

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

QString availableLabel ( self )

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

QListWidget availableListWidget ( self )

Returns:: The QListWidget holding the available actions

bool eventFilter	(	self,
		QObject	a0,
		QEvent	a1
	)

Reimplemented for internal reasons.

keyPressEvent	(	self,
		QKeyEvent	a0
	)

Reimplamented for internal reasons.

bool keyboardEnabled ( self )

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.

@sa setKeyboardEnabled()

bool moveOnDoubleClick ( self )

Returns:: Whether moveOnDoubleClcik is enabled.

If enabled, an item in any listbox will be moved to the other one whenever doubleclicked. This feature is enabled by default. @sa setMoveOnDoubleClick()

polish ( self )

Reimplemented for internal reasons. (calls setButtonsEnabled())

KActionSelector.InsertionPolicy selectedInsertionPolicy ( self )

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

QString selectedLabel ( self )

Returns:: the label of the selected items listbox.

QListWidget selectedListWidget ( self )

Returns:: The QListWidget holding the selected actions

setAvailableInsertionPolicy	(	self,
		KActionSelector.InsertionPolicy	policy
	)

Sets the insertion policy for the available listbox. See also InsertionPolicy, availableInsertionPolicy().

setAvailableLabel	(	self,
		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.

setButtonIcon	(	self,
		QString	icon,
		KActionSelector.MoveButton	button
	)

		QIcon	iconset,
		KActionSelector.MoveButton	button
	)

Sets the iconset for button button to iconset. You can use this method to et a costum icon set. Either created by QIconSet, or use the application instance of KIconLoader (recommended).
