事件類型

範例

以下程式碼範例示範如何設定 Text、 Overflow和 TextDirection 屬性，並處理事件。Click 要執行此範例，請將以下程式碼貼入包含ToolStrip該表單建構子或movingToolStrip事件處理程序中命名InitializeMovingToolStrip與呼叫Load的表單中。

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

事件會 Click 將 傳遞 EventArgs 給事件處理器，因此只會表示點擊發生。 如果你需要更具體的滑鼠資訊（按鈕、點擊次數、滾輪旋轉或位置），可以使用 MouseDown and MouseUp 事件，將 a MouseEventArgs 傳給事件處理器。

雙擊鍵由使用者作業系統的滑鼠設定決定。 使用者可以設定滑鼠按鍵點擊間隔時間，這應該視為雙擊而非兩次點擊。 每當雙擊控制項時，事件 Click 就會被觸發。 例如，若你有兩個事件處理程序，負責 Click 和 DoubleClickFormClick事件，當雙擊表單並呼叫兩個方法時，和DoubleClick事件會被觸發。 如果雙擊項目不支援該 DoubleClick 事件， Click 事件可能會被觸發兩次。
