Menentukan kelas ProfessionalColorTable Kustom

Gradien kustom didefinisikan di CustomProfessionalColors kelas .

// This class defines the gradient colors for
// the MenuStrip and the ToolStrip.
class CustomProfessionalColors : ProfessionalColorTable
{
    public override Color ToolStripGradientBegin
    { get { return Color.BlueViolet; } }

    public override Color ToolStripGradientMiddle
    { get { return Color.CadetBlue; } }

    public override Color ToolStripGradientEnd
    { get { return Color.CornflowerBlue; } }

    public override Color MenuStripGradientBegin
    { get { return Color.Salmon; } }

    public override Color MenuStripGradientEnd
    { get { return Color.OrangeRed; } }
}

' This class defines the gradient colors for 
' the MenuStrip and the ToolStrip.
Class CustomProfessionalColors
   Inherits ProfessionalColorTable
   
   Public Overrides ReadOnly Property ToolStripGradientBegin() As Color
      Get
         Return Color.BlueViolet
      End Get 
   End Property
   
   Public Overrides ReadOnly Property ToolStripGradientMiddle() As Color
      Get
         Return Color.CadetBlue
      End Get 
   End Property
   
   Public Overrides ReadOnly Property ToolStripGradientEnd() As Color
      Get
         Return Color.CornflowerBlue
      End Get 
   End Property
   
   Public Overrides ReadOnly Property MenuStripGradientBegin() As Color
      Get
         Return Color.Salmon
      End Get 
   End Property
   
   Public Overrides ReadOnly Property MenuStripGradientEnd() As Color
      Get
         Return Color.OrangeRed
      End Get
    End Property

End Class

Menetapkan Perender Kustom

Buat baru ToolStripProfessionalRenderer dengan CustomProfessionalColors kelas , dan tetapkan ke ToolStripManager.Renderer properti .

// This event handler is invoked when the "Change colors"
// ToolStripItem is clicked. It assigns the Renderer
// property for the ToolStrip control.
void ChangeColors_Click(object sender, EventArgs e)
{
    ToolStripManager.Renderer =
        new ToolStripProfessionalRenderer(new CustomProfessionalColors());
}

' This event handler is invoked when the "Change colors"
' ToolStripItem is clicked. It assigns the Renderer
' property for the ToolStrip control.
 Sub ChangeColors_Click(ByVal sender As Object, ByVal e As EventArgs)
     ToolStripManager.Renderer = New ToolStripProfessionalRenderer(New CustomProfessionalColors())
 End Sub
