Beispiele

Im folgenden Codebeispiel wird ein TabControl mit einem TabPageerstellt. In diesem Beispiel wird die ImageList -Eigenschaft verwendet, um Bilder aus der Auflistung anzuzeigen, die durch den ImageList namen myImagesdefiniert wird, auf den Registerkarten von tabControl1.

using namespace System::Drawing;

public ref class Form1: public Form

      ResourceManager^ resources = gcnew ResourceManager( Form1::typeid );
      TabControl^ tabControl1 = gcnew TabControl;
      TabPage^ tabPage1 = gcnew TabPage;
      
      // Declares and instantiates the ImageList Object*.
      ImageList^ myImages = gcnew ImageList( components );
      tabControl1->Controls->Add( tabPage1 );
      
      // Sets the images in myImages to display on the tabs of tabControl1. 
      tabControl1->ImageList = myImages;
