TJamSystemImageList

The TJamSystemImageList component provides access to the system image list of Windows, enabling you to display shell-related information in a Delphi TListView, TreeView, or similar controls supporting ImageLists.

Simply place the component on your form and assign it to the Images property of the TListView or TTreeView. Use the Size property to switch between small and large icons. GetIndexFromExtension and GetIndexFromFileName will return the icon number for a given extension or filename. Use the Draw and GetBitmap methods of Delphi`s TCustomImageList component to draw an icon on a TCanvas or to retrieve it as bitmap.

The TJamSystemImageList is used in the disk space management software TreeSize to include the Windows system images.
