Constructors

SegmentedBar()

Initializes a new instance of the class.

public SegmentedBar()

Properties

IsAnimationEnabled

Whether animation is enabled.

public bool IsAnimationEnabled { get; set; }

Property Value

bool:

The default value is true.

Orientation

The orientation of the control.

public Orientation Orientation { get; set; }

Property Value

Orientation:

The default value is Avalonia.Layout.Orientation.Horizontal.

ScrollButtonTheme

The control theme applied to scroll buttons when overflowed.

public ControlTheme? ScrollButtonTheme { get; set; }

Property Value

ControlTheme

SelectionTemplate

The data template for the element which appears behind the currently selected item.

public IDataTemplate? SelectionTemplate { get; set; }

Property Value

Methods

CreateContainerForItemOverride(object?, int, object?)

Creates or a container that can be used to display an item.

protected override Control CreateContainerForItemOverride(object? item, int index, object? recycleKey)
Parameter Type Description
item object
index int
recycleKey object

Returns

Control

NeedsContainerOverride(object?, int, out object?)

Determines whether the specified item can be its own container.

protected override bool NeedsContainerOverride(object? item, int index, out object? recycleKey)
Parameter Type Description
item object

The item to check.
index int

The index of the item.
recycleKey object

When the method returns, contains a key that can be used to locate a previously recycled container of the correct type, or null if the item cannot be recycled. If the item is its own container then by definition it cannot be recycled, so recycleKey shoud be set to null.

Returns

bool:

true if the item needs a container; otherwise false if the item can itself be used as a container.

OnApplyTemplate(TemplateAppliedEventArgs)

Called when the control's template is applied. In simple terms, this means the method is called just before the control is displayed.

protected override void OnApplyTemplate(TemplateAppliedEventArgs e)
Parameter Type Description
e TemplateAppliedEventArgs

The event args.

OnCreateAutomationPeer()

Returns a new, type-specific Avalonia.Automation.Peers.AutomationPeer implementation for the control.

protected override AutomationPeer OnCreateAutomationPeer()

Returns

AutomationPeer:

The type-specific Avalonia.Automation.Peers.AutomationPeer implementation.

OnKeyDown(KeyEventArgs)

Handles directional navigation within the Avalonia.Controls.ItemsControl.

protected override void OnKeyDown(KeyEventArgs e)
Parameter Type Description
e KeyEventArgs

The key events.

OnLoaded(RoutedEventArgs)

Invoked just before the Avalonia.Controls.Control.Loaded event.

protected override void OnLoaded(RoutedEventArgs e)
Parameter Type Description
e RoutedEventArgs

The event args.

OnTemplateChanged(AvaloniaPropertyChangedEventArgs)

Called when the Avalonia.Controls.Primitives.TemplatedControl.Template property changes.

protected override void OnTemplateChanged(AvaloniaPropertyChangedEventArgs e)
Parameter Type Description
e AvaloniaPropertyChangedEventArgs

The event args.

ToString()

Returns the string representation of this object.

public override string ToString()

Returns

string:

The string representation of this object.
