Methods

CoerceAllProperties()

Requests all coerced properties to be coerced.

protected virtual void CoerceAllProperties()

MeasureOverride(Size)

Measures the control and its child elements as part of a layout pass.

protected override Size MeasureOverride(Size availableSize)
Parameter Type Description
availableSize Size

The size available to the control.

Returns

Size:

The desired size for the control.

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.

ToString()

Returns the string representation of this object.

public override string ToString()

Returns

string:

The string representation of this object.
