ToolStripItem.AutoSize 屬性

定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

取得或設定值，指出項目是否會自動調整大小。

public:
 property bool AutoSize { bool get(); void set(bool value); };

public bool AutoSize { get; set; }

member this.AutoSize : bool with get, set

Public Property AutoSize As Boolean

屬性值

Boolean

如果 ToolStripItem 會自動調整大小，則為 true，否則為 false。 預設值是 true。

範例

下列程式碼範例示範如何設定 Text 、 AutoSize 、 Overflow 和 TextDirection 屬性，以及處理 Click 事件。 若要執行此範例，請將下列程式碼貼到表單 ToolStrip 中包含具名 movingToolStrip 的 表單，並在表單的建構函式或 Load 事件處理常式中呼叫 InitializeMovingToolStrip 。

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

將 AutoSize 屬性設定為 true ，讓 ToolStripItem 調整其高度或寬度，視 的方向 ToolStrip 而定，以確保 ToolStripItem 只使用所需的空間量。

ToolStripItem如果 屬性為 ，則 AutoSize 其大小下限。 true 如果您想要 ToolStripItem 小於系統定義的最小大小或大小 ToolStripItem 為零，請將 AutoSize 屬性 false 設定為 。
