Esempio

Nell'esempio di codice seguente viene illustrato come eseguire l'override del OnRenderToolStripBackground metodo per disegnare una sfumatura in background di un ToolStrip controllo. Questo esempio di codice fa parte di un esempio più grande fornito per la ToolStripRenderer classe.

// This method renders the GridStrip control's background.
protected override void OnRenderToolStripBackground(
    ToolStripRenderEventArgs e)
{
    base.OnRenderToolStripBackground(e);

    // This late initialization is a workaround. The gradient
    // depends on the bounds of the GridStrip control. The bounds 
    // are dependent on the layout engine, which hasn't fully
    // performed layout by the time the Initialize method runs.
    if (this.backgroundBrush == null)
    {
        this.backgroundBrush = new LinearGradientBrush(
           e.ToolStrip.ClientRectangle,
           SystemColors.ControlLightLight,
           SystemColors.ControlDark,
           90,
           true);
    }

    // Paint the GridStrip control's background.
    e.Graphics.FillRectangle(
        this.backgroundBrush, 
        e.AffectedBounds);
}

' This method renders the GridStrip control's background.
Protected Overrides Sub OnRenderToolStripBackground(e As ToolStripRenderEventArgs)
   MyBase.OnRenderToolStripBackground(e)
   
   ' This late initialization is a workaround. The gradient
   ' depends on the bounds of the GridStrip control. The bounds 
   ' are dependent on the layout engine, which hasn't fully
   ' performed layout by the time the Initialize method runs.
   If Me.backgroundBrush Is Nothing Then
      Me.backgroundBrush = New LinearGradientBrush(e.ToolStrip.ClientRectangle, SystemColors.ControlLightLight, SystemColors.ControlDark, 90, True)
   End If
   
   ' Paint the GridStrip control's background.
   e.Graphics.FillRectangle(Me.backgroundBrush, e.AffectedBounds)
  End Sub
