Public Sub Draw (g As Graphics, pt As Point, index As Integer)

Parameters

g: Graphics

The Graphics to draw on.

pt: Point

The location defined by a Point at which to draw the image.

Examples

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.

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

   // 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++ )
