获取或设置控件的选项卡的大小。

public:
 property System::Drawing::Size ItemSize { System::Drawing::Size get(); void set(System::Drawing::Size value); };

public System.Drawing.Size ItemSize { get; set; }

member this.ItemSize : System.Drawing.Size with get, set

Public Property ItemSize As Size

属性值

Size

Size，它表示选项卡的大小。 默认为自动调整选项卡的大小以适应选项卡上的图标和标签。

例外

ArgumentOutOfRangeException

Size 的宽度或高度小于 0。

示例

下面的代码示例创建一个包含两TabPage个TabControl对象的对象。 若要定义选项卡的维度，请将属性设置为 ItemSize 等于结构 Size 。 在此示例中， Size 定义 90 像素宽和 50 像素高的选项卡。 除非属性 SizeMode 设置为 Fixed 值，否则不能更改选项卡的宽度。

using namespace System::Drawing;
using namespace System::Windows::Forms;
public ref class Form1: public Form
{
private:
   TabControl^ tabControl1;
   TabPage^ tabPage1;
   TabPage^ tabPage2;

public:
   Form1()
   {
      this->tabControl1 = gcnew TabControl;
      this->tabPage1 = gcnew TabPage;
      this->tabPage2 = gcnew TabPage;
      
      // Sizes the tabs of tabControl1.
      this->tabControl1->ItemSize = System::Drawing::Size( 90, 50 );
      
      // Makes the tab width definable. 
      this->tabControl1->SizeMode = TabSizeMode::Fixed;
      array<Control^>^tabControl1Controls = {tabPage1,tabPage2};
      this->tabControl1->Controls->AddRange( tabControl1Controls );
      this->tabControl1->Location = Point(35,25);
      this->tabControl1->Size = System::Drawing::Size( 220, 220 );
      this->Size = System::Drawing::Size( 300, 300 );
      this->Controls->Add( tabControl1 );
   }

};

int main()
{
   Application::Run( gcnew Form1 );
}

using System.Drawing;
using System.Windows.Forms;

public class Form1 : Form
{
    private TabControl tabControl1;
    private TabPage tabPage1;
    private TabPage tabPage2;

    public Form1()
    {
        this.tabControl1 = new TabControl();
        this.tabPage1 = new TabPage();
        this.tabPage2 = new TabPage();
        
        // Sizes the tabs of tabControl1.
        this.tabControl1.ItemSize = new Size(90, 50);

        // Makes the tab width definable. 
        this.tabControl1.SizeMode = TabSizeMode.Fixed;

        this.tabControl1.Controls.AddRange(new Control[] {
            tabPage1, tabPage2});
        this.tabControl1.Location = new Point(35, 25);
        this.tabControl1.Size = new Size(220, 220);

        this.Size = new Size(300, 300);
        this.Controls.Add(tabControl1);
    }

    static void Main() 
    {
        Application.Run(new Form1());
    }
}

Imports System.Drawing
Imports System.Windows.Forms

Public Class Form1
    Inherits Form
    Private tabControl1 As TabControl
    Private tabPage1 As TabPage
    Private tabPage2 As TabPage

    Public Sub New()
        Me.tabControl1 = New TabControl()
        Me.tabPage1 = New TabPage()
        Me.tabPage2 = New TabPage()

        ' Sizes the tabs of tabControl1.
        Me.tabControl1.ItemSize = New Size(90, 50)

        ' Makes the tab width definable. 
        Me.tabControl1.SizeMode = TabSizeMode.Fixed

        Me.tabControl1.Controls.AddRange(New Control() {tabPage1, tabPage2})
        Me.tabControl1.Location = New Point(35, 25)
        Me.tabControl1.Size = New Size(220, 220)

        Me.Size = New Size(300, 300)
        Me.Controls.Add(tabControl1)
    End Sub

    Shared Sub Main()
        Application.Run(New Form1())
    End Sub
End Class

注解

若要更改 Width 属性的属性 ItemSize ， SizeMode 必须将该属性设置为 Fixed。
