This topic provides information about Automatización de la interfaz de usuario support for the Slider control type. In Automatización de la interfaz de usuario, a control type is a set of conditions that a control must meet in order to use the ControlTypeProperty property. The conditions include specific guidelines for Automatización de la interfaz de usuario tree structure, Automatización de la interfaz de usuario property values and control types.

The Slider control is a composite control with buttons that enable a user with a mouse to set a numerical range or select from a set of items.

The following sections define the required Automatización de la interfaz de usuario tree structure, properties, control patterns, and events for the Slider control type. The Automatización de la interfaz de usuario requirements apply to all slider controls, whether Windows Presentation Foundation (WPF), Win32, or formularios Windows Forms.

Required UI Automation Tree Structure

The following table depicts the Control View and the Content View of the Automatización de la interfaz de usuario tree that pertains to slider controls and describes what can be contained in each view. For more information on the Automatización de la interfaz de usuario tree, see UI Automation Tree Overview.

Control View	Content View
Slider Button (2 or 4) Thumb (only 1) List Item (2 or more)	Slider List Item (2 or more)

Required UI Automation Properties

The following table lists the Automatización de la interfaz de usuario properties whose value or definition is especially relevant to the Slider control type. For more information on Automatización de la interfaz de usuario properties, see UI Automation Properties for Clients.

Automatización de la interfaz de usuario Property	Value	Notes
AutomationIdProperty()	See notes.	The value of this property needs to be unique across all controls in an application.
BoundingRectangleProperty	See notes.	The outermost rectangle that contains the whole control.
ClickablePointProperty	See notes	The majority of slider controls must raise the NoClickablePointException because the entire bounding rectangle of the slider control is occupied by child controls.
IsKeyboardFocusableProperty	See notes.	If the control can receive keyboard focus, it must support this property.
NameProperty	See notes.	The name of the edit control is typically generated from a static text label. If there is not a static text label, a property value for Name must be assigned by the application developer. The Name property should never contain the textual contents of the edit control.
LabeledByProperty	See notes.	If there is a static text label associated with the control, then this property must expose a reference to that control. If the text control is a subcomponent of another control, it will not have a LabeledBy property set.
ControlTypeProperty	Slider	This value is the same for all interfaz de usuario frameworks.
LocalizedControlTypeProperty	"slider"	Localized string corresponding to the Edit Control Type.
IsContentElementProperty	True	The edit control is always included in the content view of the Automatización de la interfaz de usuario tree.
IsControlElementProperty	True	The edit control is always included in the control view of the Automatización de la interfaz de usuario tree.

Required UI Automation Control Patterns

The following table lists the Automatización de la interfaz de usuario control patterns required to be supported by all slider controls. For more information on control patterns, see Información general acerca de los patrones de control de automatización de la interfaz de usuario.

Control Pattern/Control Pattern Property	Support/Value	Notes
ISelectionProvider	Depends	Depends on whether contents are discrete values
IRangeValueProvider	Depends	Depends on whether contents can be set within numerical range.

Required UI Automation Events

The following table lists the Automatización de la interfaz de usuario events required to be supported by all slider controls.

For more information on events, see UI Automation Events Overview.

Automatización de la interfaz de usuario Event	Support	Notes
InvalidatedEvent	Depends	None
BoundingRectangleProperty	Required	None
IsOffscreenProperty	Required	None
IsEnabledProperty	Required	None
ValueProperty	Depends	None
AutomationFocusChangedEvent	Required	None
