TabControl.Multiline 属性

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

获取或设置一个值，该值指示是否可以显示一行以上的选项卡。

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

public bool Multiline { get; set; }

member this.Multiline : bool with get, set

Public Property Multiline As Boolean

属性值

Boolean

如果可以显示一行以上的选项卡，则为 true；否则为 false。 默认值为 false。

示例

下面的代码示例创建一个包含四TabPage个TabControl对象的对象。 属性 Multiline 设置为 true，它显示两行制表符，而不是一行。

using namespace System::Drawing;
using namespace System::Windows::Forms;
public ref class Form1: public Form
{
private:
   TabControl^ tabControl1;
   TabPage^ tabPage1;
   TabPage^ tabPage2;
   TabPage^ tabPage3;
   TabPage^ tabPage4;
   void MyTabs()
   {
      this->tabControl1 = gcnew TabControl;
      this->tabPage1 = gcnew TabPage;
      this->tabPage2 = gcnew TabPage;
      this->tabPage3 = gcnew TabPage;
      this->tabPage4 = gcnew TabPage;
      
      // Allows more than one row of tabs.
      this->tabControl1->Multiline = true;
      this->tabControl1->Padding = Point(22,5);
      array<Control^>^tabControls = {this->tabPage1,this->tabPage2,this->tabPage3,this->tabPage4};
      this->tabControl1->Controls->AddRange( tabControls );
      this->tabControl1->Location = Point(35,25);
      this->tabControl1->Size = System::Drawing::Size( 220, 220 );
      this->tabPage1->Text = "myTabPage1";
      this->tabPage2->Text = "myTabPage2";
      this->tabPage3->Text = "myTabPage3";
      this->tabPage4->Text = "myTabPage4";
      this->Size = System::Drawing::Size( 300, 300 );
      array<Control^>^formControls = {this->tabControl1};
      this->Controls->AddRange( formControls );
   }

        this.tabControl1.Location = new Point(35, 25);
        this.tabControl1.Size = new Size(220, 220);

        Me.Controls.AddRange(New Control() {Me.tabControl1})
    End Sub

    Public Sub New()
        MyTabs()
    End Sub

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

注解

false如果是Multiline，则仅显示一行制表符，即使所有选项卡都不适合可用空间。 但是，在这种情况下，将显示箭头，使用户能够导航到未显示选项卡。

Multiline如果属性设置为Alignmentfalse或属性设置为Left时Right更改为该属性，则Alignment属性将自动重置为 Top。
