操作說明：定義停駐之 ToolStrip 控制項的疊置順序

  • 發行項

若要使用停駐將 ToolStrip 控制項正確地定位，您必須依照表單的疊置順序，將控制項正確地定位。

範例

下列程式碼範例示範如何指定疊置順序，以排列 ToolStrip 控制項和停駐的 MenuStrip 控制項。

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);
}

Class Form2
   Inherits Form
   
   Public Sub New()
      ' Create a new ToolStrip control.
      Dim ts As New ToolStrip()
      
      ' Populate the ToolStrip control.
      ts.Items.Add("Apples")
      ts.Items.Add("Oranges")
      ts.Items.Add("Pears")
      ts.Items.Add("Change Colors", Nothing, New EventHandler(AddressOf ChangeColors_Click))
      
      ' Create a new MenuStrip.
      Dim ms As 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.
      Me.Controls.Add(ts)
      
      ' Add the MenuStrip control last.
      ' This is important for correct placement in the z-order.
      Me.Controls.Add(ms)
    End Sub
   
   ' 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
End Class

堆疊順序取決於 ToolStrip 和 MenuStrip 的順序

控制項會新增至表單的 Controls 集合。

// 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);

' Add the ToolStrip to Controls collection.
Me.Controls.Add(ts)

' Add the MenuStrip control last.
' This is important for correct placement in the z-order.
Me.Controls.Add(ms)

將對 Add 方法的這些呼叫順序反轉，並檢視配置上的效果。
