TabControl.ImageList Eigenschap

Definitie

Hiermee haalt u de afbeeldingen op of stelt u deze in om weer te geven op de tabbladen van het besturingselement.

public:
 property System::Windows::Forms::ImageList ^ ImageList { System::Windows::Forms::ImageList ^ get(); void set(System::Windows::Forms::ImageList ^ value); };
public System.Windows.Forms.ImageList ImageList { get; set; }
public System.Windows.Forms.ImageList? ImageList { get; set; }
member this.ImageList : System.Windows.Forms.ImageList with get, set
Public Property ImageList As ImageList

Waarde van eigenschap

Een ImageList die de afbeeldingen opgeeft die op de tabbladen moeten worden weergegeven.

Voorbeelden

In het volgende codevoorbeeld wordt een TabControl met één TabPagegemaakt. In dit voorbeeld wordt de ImageList eigenschap gebruikt om afbeeldingen weer te geven uit de verzameling die is gedefinieerd door de ImageList benoemde myImages, op de tabbladen van tabControl1.

using namespace System::Drawing;
using namespace System::ComponentModel;
using namespace System::Windows::Forms;
using namespace System::Resources;
public ref class Form1: public Form
{
public:
   Form1()
   {
      IContainer^ components = gcnew System::ComponentModel::Container;
      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;
      tabPage1->ImageIndex = 0;
      tabPage1->Text = "tabPage1";
      
      // Gets the handle that provides the data of myImages.
      myImages->ImageStream = (dynamic_cast<ImageListStreamer^>(resources->GetObject( "myImages.ImageStream" )));
      
      // Sets properties of myImages. 
      myImages->ColorDepth = ColorDepth::Depth8Bit;
      myImages->ImageSize = System::Drawing::Size( 16, 16 );
      myImages->TransparentColor = Color::Transparent;
      this->Controls->Add( tabControl1 );
   }

Opmerkingen

Als u een afbeelding op een tabblad wilt weergeven, stelt u de ImageIndex eigenschap daarvan TabPagein. De ImageIndex fungeert als de index in de ImageList.
