SystemColors Class

Definition

Each property of the SystemColors class is a Color structure that is the color of a Windows display element.

public ref class SystemColors abstract sealed
public ref class SystemColors sealed
public static class SystemColors
public sealed class SystemColors
type SystemColors = class
Public Class SystemColors
Public NotInheritable Class SystemColors
Inheritance
SystemColors

Examples

The following code example demonstrates the Equality operator and the SystemColors class. This example is designed to be used with a Windows Form that contains a button named Button1. Paste the following code into your form and associate the Button1_Click method with the button's Click event.

void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   if ( this->BackColor == SystemColors::ControlDark )
   {
      this->BackColor = SystemColors::Control;
   }
}
private void Button1_Click(System.Object sender, System.EventArgs e)
{

    if (this.BackColor == SystemColors.ControlDark)
    {
        this.BackColor = SystemColors.Control;
    }
}
Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click

    If (Color.op_Equality(Me.BackColor, SystemColors.ControlDark)) Then
        Me.BackColor = SystemColors.Control
    End If
End Sub

Remarks

Better performance is achieved by using the properties of the SystemPens or SystemBrushes classes rather than creating a new pen or brush based on a value from SystemColors. For example, if you wanted to get a brush for the face color of a 3-D element, use the SystemBrushes.Control property because it gets a brush that already exists, whereas calling the SolidBrush constructor with a parameter value of SystemColors.Control will create a new brush.
