Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie die TickStyleEigenschaften , Minimumund Maximum verwendet und wie das ValueChanged Ereignis behandelt wird. Fügen Sie zum Ausführen des Beispiels den folgenden Code in ein Formular ein, das ein TrackBar Steuerelement namens TrackBar1 und ein TextBox Steuerelement mit dem Namen TextBox1enthält. Rufen Sie die InitializeTrackBar -Methode aus dem Konstruktor oder Load der Ereignisbehandlungsmethode des Formulars auf.

   //Declare a new TrackBar object.
internal:
   System::Windows::Forms::TrackBar^ TrackBar1;

   // Initialize the TrackBar and add it to the form.

      this->TrackBar1 = gcnew System::Windows::Forms::TrackBar;
      TrackBar1->Location = System::Drawing::Point( 75, 30 );
      
      // Set the TickStyle property so there are ticks on both sides
      // of the TrackBar.
      TrackBar1->TickStyle = TickStyle::Both;
      
      // Set the minimum and maximum number of ticks.
      TrackBar1->Minimum = 10;

      // Set the tick frequency to one tick every ten units.

      // Associate the event-handling method with the 
      // ValueChanged event.
