Methods

CalculateAvailableSize(Size)

Calculates the available size for the panel and its children based on the System.Windows.Size passed to the System.Windows.FrameworkElement.MeasureOverride. The positive and negative infinity values are replaced with 0.

Declaration

protected static Size CalculateAvailableSize(Size availableSize)

Parameters

System.Windows.Size availableSize The System.Windows.Size passed to the System.Windows.FrameworkElement.MeasureOverride.

Returns

System.Windows.Size The System.Windows.Size with replaced positive and negative infinity with 0.

CalculateItemSize(Int64)

Calculates the size of an item in pixels based on the period in System.TimeSpan.Ticks that this item represents.

Declaration

protected virtual double CalculateItemSize(long ticks)

Parameters

System.Int64 ticks The period in System.TimeSpan.Ticks that the item represents.

Returns

System.Double The size of the item in pixels.

CalculatePixelsPerTick(Double)

Calculates the number of pixels per tick based on the specified System.Windows.FrameworkElement.Width of the panel.

Declaration

protected virtual double CalculatePixelsPerTick(double size)

Parameters

System.Double size The System.Windows.FrameworkElement.Width of the panel.

Returns

System.Double The number of pixels per tick.

CalculatePixelsPerTick(Double, Int64)

Calculates the number of pixels per tick based on the specified System.Windows.FrameworkElement.Width of the panel and the period in System.TimeSpan.Ticks it visualizes.

Declaration

protected static double CalculatePixelsPerTick(double size, long ticks)

Parameters

System.Double size The System.Windows.FrameworkElement.Width of the panel.

System.Int64 ticks The period in System.TimeSpan.Ticks that the panel visualizes.

Returns

System.Double The number of pixels per tick.

OnSizeChanged(Object, SizeChangedEventArgs)

Called when either the System.Windows.FrameworkElement.ActualHeight or the System.Windows.FrameworkElement.ActualWidth properties change value on this panel.

Declaration

protected virtual void OnSizeChanged(object sender, SizeChangedEventArgs e)

Parameters

System.Object sender The panel where the event handler is attached.

System.Windows.SizeChangedEventArgs e The System.Windows.SizeChangedEventArgs instance containing the event data.

UpdateScroll(Size)

Updates the properties of the panel based on the state of the Slider. This method should be called in System.Windows.FrameworkElement.MeasureOverride before the size of the children of the panel are calculated.

Declaration

protected virtual void UpdateScroll(Size size)

Parameters

System.Windows.Size size The System.Windows.Size passed to the System.Windows.FrameworkElement.MeasureOverride.
