ToolStripItem.AutoSize 屬性


取得或設定值,指出項目是否會自動調整大小。Gets or sets a value indicating whether the item is automatically sized.

 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


如果 true 會自動調整大小,則為 ToolStripItem,否則為 falsetrue if the ToolStripItem is automatically sized; otherwise, false. 預設值是 trueThe default value is true.


下列程式碼範例示範如何設定 TextAutoSizeOverflowTextDirection 屬性,以及處理 Click 事件。The following code example demonstrates how to set the Text, AutoSize, Overflow, and TextDirection properties, and handle the Click event. 若要執行此範例,請將下列程式碼貼入包含名為 movingToolStripToolStrip 的表單中,並在表單的函式或 Load 事件處理常式中呼叫 InitializeMovingToolStripTo 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 = 
    changeDirectionButton->Overflow = 
    changeDirectionButton->Text = "Change Alignment";
    changeDirectionButton->Click += gcnew EventHandler(this, 

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;
        item->TextDirection = 
        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";

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;
        item.TextDirection = ToolStripTextDirection.Vertical270;
        movingToolStrip.Dock = System.Windows.Forms.DockStyle.Left;

        OrElse item.TextDirection = ToolStripTextDirection.Vertical90 Then

        item.TextDirection = ToolStripTextDirection.Horizontal
        movingToolStrip.Dock = System.Windows.Forms.DockStyle.Top

    End If

End Sub


將 [AutoSize] 屬性設定為 [true],讓 ToolStripItem 調整其高度或寬度(視 ToolStrip的方向而定),以確保 ToolStripItem 只會使用所需的空間量。Set the AutoSize property to true to cause the ToolStripItem to adjust either its height or width, depending on the orientation of the ToolStrip, to ensure that the ToolStripItem uses only the required amount of space.

如果 trueAutoSize 屬性,ToolStripItem 的大小下限。A ToolStripItem has a minimum size if the AutoSize property is true. 如果您想要 ToolStripItem 小於系統定義的大小下限,或 ToolStripItem 的大小為零,請將 AutoSize 屬性設定為 [false]。Set the AutoSize property to false if you want a ToolStripItem to be smaller than the system-defined minimum size or to have a ToolStripItem size of zero.
