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

public bool HotTrack { get; set; }

Beispiele

Im folgenden Codebeispiel wird ein TabControl mit zwei TabPage -Objekten erstellt. Die HotTrack -Eigenschaft ist auf truefestgelegt, wodurch die Registerkarte TextmyTabPage1 hervorgehoben wird, oder myTabPage2 wenn die Maus über die Registerkarten geht.

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;
      this->tabPage1->Text = "myTabPage1";
      this->tabPage2->Text = "myTabPage2";
      this->Size = System::Drawing::Size( 300, 300 );
      array<Control^>^formControls = {this->tabControl1};
      this->Controls->AddRange( formControls );
   }

Hinweise

Die Farbe, in die die Registerkarte geändert wird, wenn die Maus darauf ist, wird durch die Systemfarben des lokalen Computers bestimmt. Verwenden Sie zum Ändern der Systemfarben Systemsteuerung.
