Voorbeelden

In het volgende codevoorbeeld ziet u hoe u de TickStyle, Minimumen eigenschappen en Maximum hoe u de ValueChanged gebeurtenis kunt afhandelen. Als u het voorbeeld wilt uitvoeren, plakt u de volgende code in een formulier dat een TrackBar besturingselement met de naam TrackBar1 en een besturingselement met de TextBox naam TextBox1bevat. Roep de methode aan vanuit de InitializeTrackBar constructor of Load gebeurtenisafhandelingsmethode van het formulier.

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

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

   {
      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;
      TrackBar1->Maximum = 100;
      
      // Set the tick frequency to one tick every ten units.
      TrackBar1->TickFrequency = 10;
      
      // Associate the event-handling method with the 
      // ValueChanged event.
      TrackBar1->ValueChanged += gcnew System::EventHandler( this, &Form1::TrackBar1_ValueChanged );
      this->Controls->Add( this->TrackBar1 );
   }

   // Handle the TrackBar.ValueChanged event by calculating a value for
   // TextBox1 based on the TrackBar value.  
   void TrackBar1_ValueChanged( Object^ /*sender*/, System::EventArgs^ /*e*/ )
