Namespace: DevExpress.Xpf.Gauges

Assembly: DevExpress.Xpf.Gauges.v21.2.dll

NuGet Package: DevExpress.Wpf.Gauges

Declaration

C#

public SymbolLength(
    SymbolLengthType type,
    double length
)

VB.NET

Public Sub New(
    type As SymbolLengthType,
    length As Double
)

Parameters

Name	Type	Description
type	SymbolLengthType	A SymbolLengthType enumeration value that specifies the type of a symbol length. This value is assigned to the SymbolLength.Type property.
length	Double	A Double value that specifies the symbol length. This value is assigned to either the SymbolLength.FixedLength or SymbolLength.ProportionalLength property, depending on the value passed as the type parameter.

Example

This example demonstrates how to specify the width and height of digital gauge symbols in fixed and proportional values.

For this, it is necessary to create an instance of the SymbolLength structure with required values and then assign it to the SymbolViewBase.Height and SymbolViewBase.Width properties.

In this example, the symbol length can be set either in fixed or proportional values depending on which of the buttons has been clicked.

View Example

MainWindow.xaml.cs

// Specify fixed values for symbol height and width.
SymbolLength newWidth = new SymbolLength(SymbolLengthType.Fixed, 44);
matrixView.Width = newWidth;
SymbolLength newHeight = new SymbolLength(SymbolLengthType.Fixed, 50);
matrixView.Height = newHeight;
// Specify proportional values for symbol height and width.
SymbolLength newWidth = new SymbolLength(SymbolLengthType.Proportional, 2);
matrixView.Width = newWidth;
SymbolLength newHeight = new SymbolLength(SymbolLengthType.Proportional, 5);
matrixView.Height = newHeight;

MainWindow.xaml.vb

' Specify fixed values for symbol height and width.
Dim newWidth As New SymbolLength(SymbolLengthType.Fixed, 44)
matrixView.Width = newWidth
Dim newHeight As New SymbolLength(SymbolLengthType.Fixed, 50)
matrixView.Height = newHeight
' Specify proportional values for symbol height and width.
Dim newWidth As New SymbolLength(SymbolLengthType.Proportional, 2)
matrixView.Width = newWidth
Dim newHeight As New SymbolLength(SymbolLengthType.Proportional, 5)
matrixView.Height = newHeight
