方法: ToolStrip アプリケーションの色をカスタマイズする

  • [アーティクル]

ToolStripProfessionalRenderer クラスを使用して、カスタマイズした色を使用すると、ToolStrip の外観をカスタマイズできます。

例

次のコード例は、ToolStripProfessionalRenderer を使用してカスタム カラーを実行時に定義する方法を示します。

// This code example demonstrates how to use a ProfessionalRenderer
// to define custom professional colors at runtime.
class Form2 : Form
{
    public Form2()
    {
        // Create a new ToolStrip control.
        ToolStrip ts = new ToolStrip();

        // Populate the ToolStrip control.
        ts.Items.Add("Apples");
        ts.Items.Add("Oranges");
        ts.Items.Add("Pears");
        ts.Items.Add(
            "Change Colors",
            null,
            new EventHandler(ChangeColors_Click));

        // Create a new MenuStrip.
        MenuStrip ms = new MenuStrip();

        // Dock the MenuStrip control to the top of the form.
        ms.Dock = DockStyle.Top;

        // Add the top-level menu items.
        ms.Items.Add("File");
        ms.Items.Add("Edit");
        ms.Items.Add("View");
        ms.Items.Add("Window");

        // Add the ToolStrip to Controls collection.
        this.Controls.Add(ts);

        // Add the MenuStrip control last.
        // This is important for correct placement in the z-order.
        this.Controls.Add(ms);
    }

    // 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 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; } }
}
