範例

下列程式碼範例示範如何設定 TextOverflowTextDirection 屬性,以及處理 Click 事件。The following code example demonstrates how to set the Text, Overflow, and TextDirection properties, and handle the Click event. 若要執行這個範例,請將下列程式碼貼入表單 ToolStrip 中, movingToolStripInitializeMovingToolStrip 在表單的函式或 Load 事件處理常式中包含指名的和呼叫。To run this example, paste the following code into a form that contains a ToolStrip named movingToolStrip and call InitializeMovingToolStrip in the form's constructor or Load event handler.

ToolStripButton^ changeDirectionButton;

void InitializeMovingToolStrip()
{
    changeDirectionButton = gcnew ToolStripButton;
    movingToolStrip->AutoSize = true;
    movingToolStrip->RenderMode = ToolStripRenderMode::System;
    changeDirectionButton->TextDirection = 
        ToolStripTextDirection::Vertical270;
    changeDirectionButton->Overflow = 
        ToolStripItemOverflow::Never;
    changeDirectionButton->Text = "Change Alignment";
    movingToolStrip->Items->Add(changeDirectionButton);
    changeDirectionButton->Click += gcnew EventHandler(this, 
        &Form1::changeDirectionButtonClick);
}

void changeDirectionButtonClick(Object^ sender, EventArgs^ e)
{
    ToolStripItem^ item = (ToolStripItem^) sender;
    if ((item->TextDirection == ToolStripTextDirection::Vertical270) 
        || (item->TextDirection == ToolStripTextDirection::Vertical90))
    {
        item->TextDirection = ToolStripTextDirection::Horizontal;
        movingToolStrip->Raft = RaftingSides::Top;
    }
    else
    {
        item->TextDirection = 
            ToolStripTextDirection::Vertical270;
        movingToolStrip->Raft = RaftingSides::Left;
    }
}


internal ToolStripButton changeDirectionButton;

private void InitializeMovingToolStrip()
{
    movingToolStrip = new ToolStrip();

    changeDirectionButton = new ToolStripButton();

    movingToolStrip.AutoSize = true;
    movingToolStrip.RenderMode = ToolStripRenderMode.System;

    changeDirectionButton.TextDirection = ToolStripTextDirection.Vertical270;
    changeDirectionButton.Overflow = ToolStripItemOverflow.Never;
    changeDirectionButton.Text = "Change Alignment";
        movingToolStrip.Items.Add(changeDirectionButton);
}

private void changeDirectionButton_Click(object sender, EventArgs e)
{

    ToolStripItem item = (ToolStripItem)sender;

    if (item.TextDirection == ToolStripTextDirection.Vertical270 || item.TextDirection == ToolStripTextDirection.Vertical90)
    {
        item.TextDirection = ToolStripTextDirection.Horizontal;
        movingToolStrip.Dock = System.Windows.Forms.DockStyle.Top;
    }
    else
    {
        item.TextDirection = ToolStripTextDirection.Vertical270;
        movingToolStrip.Dock = System.Windows.Forms.DockStyle.Left;
    }
}
Friend WithEvents changeDirectionButton As ToolStripButton

Private Sub InitializeMovingToolStrip()
    changeDirectionButton = New ToolStripButton()

    movingToolStrip.AutoSize = True
    movingToolStrip.RenderMode = ToolStripRenderMode.System

    changeDirectionButton.TextDirection = ToolStripTextDirection.Vertical270
    changeDirectionButton.Overflow = ToolStripItemOverflow.Never
    changeDirectionButton.Text = "Change Alignment"
    movingToolStrip.Items.Add(changeDirectionButton)
End Sub


Public Sub changeDirectionButton_Click(ByVal sender As Object, _
    ByVal e As EventArgs) Handles changeDirectionButton.Click

    Dim item As ToolStripItem = CType(sender, ToolStripItem)

    If item.TextDirection = ToolStripTextDirection.Vertical270 _
        OrElse item.TextDirection = ToolStripTextDirection.Vertical90 Then

        item.TextDirection = ToolStripTextDirection.Horizontal
        movingToolStrip.Dock = System.Windows.Forms.DockStyle.Top
    Else
        item.TextDirection = ToolStripTextDirection.Vertical270
        movingToolStrip.Dock = System.Windows.Forms.DockStyle.Left
    End If

End Sub

備註

Overflow在堆疊版面配置中使用屬性。Use the Overflow property in stack layouts. 在 flow 和資料表版面配置中, ToolStrip 不會轉譯溢位按鈕,因此 Overflow 會忽略屬性。In flow and table layouts, the ToolStrip overflow button is not rendered, and therefore the Overflow property is ignored.
