      this->tabPage1 = gcnew TabPage;
      this->tabPage2 = gcnew TabPage;
      this->tabPage3 = gcnew TabPage;
      
      // Positions tabs on the left side of tabControl1.
      this->tabControl1->Alignment = System::Windows::Forms::TabAlignment::Left;
      array<Control^>^tabControls = {this->tabPage1,this->tabPage2,this->tabPage3};
      this->tabControl1->Controls->AddRange( tabControls );
      this->tabControl1->Location = Point(16,24);
      this->tabControl1->SelectedIndex = 0;

注解

当属性 Alignment 设置为 Left 或 Right自动 Multiline 设置为 true该属性时。

将属性FlatButtons设置为Appearance时，仅当属性设置为Top此类Alignment时，它才会显示。 否则，该 Appearance 属性显示为设置为 Buttons 值。

将属性Buttons设置为 Appearance 时，还必须将属性Top设置为Alignment使按钮正确显示。

备注

将属性Buttons设置为Appearance时，还必须将属性Top设置为Alignment使选项卡页内容正确显示。 此外，当启用视觉样式并且属性 Alignment 设置为非 Top值时，选项卡内容可能无法正确呈现。
