TabControl.HotTrack 屬性

定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

取得或設定值，指出當滑鼠超過控件時，控件的索引標籤是否在外觀上變更。

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

public bool HotTrack { get; set; }

member this.HotTrack : bool with get, set

Public Property HotTrack As Boolean

屬性值

Boolean

當滑鼠經過索引標籤時，如果索引標籤在外觀上變更，true;否則，false。 預設值為 false。

範例

下列程式代碼範例會建立具有兩個 TabPage 物件的 TabControl。 HotTrack 屬性設定為 [true]，以醒目提示滑鼠在索引標籤上方時，索引標籤 TextmyTabPage1 或 myTabPage2。

using namespace System::Drawing;
using namespace System::Windows::Forms;
public ref class Form1: public Form
{
private:
   TabControl^ tabControl1;
   TabPage^ tabPage1;
   TabPage^ tabPage2;
   void MyTabs()
   {
      this->tabControl1 = gcnew TabControl;
      this->tabPage1 = gcnew TabPage;
      this->tabPage2 = gcnew TabPage;
      array<Control^>^tabControls = {this->tabPage1,this->tabPage2};
      this->tabControl1->Controls->AddRange( tabControls );
      this->tabControl1->Padding = Point(15,10);
      this->tabControl1->Location = Point(35,25);
      this->tabControl1->Size = System::Drawing::Size( 220, 220 );
      
      // Highlights TabPage::Text when the mouse passes over tabs.
      this->tabControl1->HotTrack = true;

備註

當滑鼠停留在索引標籤上方時，索引標籤所變更的色彩取決於本機計算機的系統色彩。 若要變更系統色彩，請使用 [控制面板]。
