Methods

ArrangeOverride(Size)

Positions child elements as part of a layout pass.

protected override Size ArrangeOverride(Size finalSize)

Parameters

finalSize Size

The size available to the control.

Returns

Size

The actual size used.

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)

Parameters

e TemplateAppliedEventArgs

The event args.

OnAttachedToVisualTree(VisualTreeAttachmentEventArgs)

Called when the control is added to a rooted visual tree.

protected override void OnAttachedToVisualTree(VisualTreeAttachmentEventArgs e)

Parameters

e VisualTreeAttachmentEventArgs

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.

OnDetachedFromVisualTree(VisualTreeAttachmentEventArgs)

Called when the control is removed from a rooted visual tree.

protected override void OnDetachedFromVisualTree(VisualTreeAttachmentEventArgs e)

Parameters

e VisualTreeAttachmentEventArgs

The event args.

OnKeyDown(KeyEventArgs)

Invoked when an unhandled Avalonia.Input.InputElement.KeyDownEvent reaches an element in its route that is derived from this class. Implement this method to add class handling for this event.

protected override void OnKeyDown(KeyEventArgs e)

Parameters

e KeyEventArgs

Data about the event.

OnPointerCaptureLost(PointerCaptureLostEventArgs)

Invoked when an unhandled Avalonia.Input.InputElement.PointerCaptureLostEvent reaches an element in its route that is derived from this class. Implement this method to add class handling for this event.

protected override void OnPointerCaptureLost(PointerCaptureLostEventArgs e)

Parameters

e PointerCaptureLostEventArgs

Data about the event.

OnPropertyChanged(AvaloniaPropertyChangedEventArgs)

Called when a avalonia property changes on the object.

protected override void OnPropertyChanged(AvaloniaPropertyChangedEventArgs change)

Parameters

change AvaloniaPropertyChangedEventArgs

The property change details.

Events

SegmentChanged

Occurs when the active segment changes.

public event EventHandler<SegmentChangedEventArgs>? SegmentChanged

Event Type

EventHandler<SegmentChangedEventArgs>
