public:
ImageList()

The following table shows initial property values for an instance of ImageList.

Item

Description

ColorDepth

In the .NET Framework version 1.0, the default is Depth4Bit. In the .NET Framework version 1.1 or later, the default is Depth8Bit.

ImageSize

The default is a Size object with a height and width of 16 by 16.

TransparentColor

The default value is Transparent.

The following code example demonstrates constructing an ImageList, adding images to the Images property, setting the ImageSize property, and using the Draw method. To run this example, place it in a form containing a button named Button1. The example assumes the existence of FeatherTexture.bmp and Gone Fishing.bmp at c:\Windows\. Change the example accordingly if the bitmaps do not exist on your system, or exist at another location.

internal:
   System::Windows::Forms::ImageList^ ImageList1;

private:

   // Create an ImageList Object, populate it, and display
   // the images it contains.
   void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {

      // Construct the ImageList.
      ImageList1 = gcnew ImageList;

      // Set the ImageSize property to a larger size 
      // (the default is 16 x 16).
      ImageList1->ImageSize = System::Drawing::Size( 112, 112 );

      // Add two images to the list.
      ImageList1->Images->Add( Image::FromFile( "c:\\windows\\FeatherTexture.bmp" ) );
      ImageList1->Images->Add( Image::FromFile( "C:\\windows\\Gone Fishing.bmp" ) );

      // Get a Graphics object from the form's handle.
      Graphics^ theGraphics = Graphics::FromHwnd( this->Handle );

      // Loop through the images in the list, drawing each image.
      for ( int count = 0; count < ImageList1->Images->Count; count++ )
      {
         ImageList1->Draw( theGraphics, Point(85,85), count );

         // Call Application.DoEvents to force a repaint of the form.
         Application::DoEvents();

         // Call the Sleep method to allow the user to see the image.
         System::Threading::Thread::Sleep( 1000 );

      }
   }
