ShellBrowser.TJamSystemImageList

The TJamSystemImageList component provides the icons of the Windows shell in from of a Delphi ImageList descendant.

ShellBrowser_TJamSystemImageList
Syntax
Pascal
TJamSystemImageList = class(TCustomImageList);

Use this component to get access to the system image list of Windows. This can be useful if you want to display shell related information in a Delphi TListView or TTreeView. Then just place a TJamSystemImageList component on your form and assign it to the Images property of the TTreeView of TListView. Use the Size property to switch between small and large icons. GetIndexFromExtension 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 somewhere on a TCanvas or to retrieve it as bitmap.

The following example will retrieve the large icon associated with Word documents as bitmap:

var index : Integer;
    bitmap: TBitmap;
begin
  index := SystemImageList.GetIndexFromExtension('doc');
  bitmap:= TBitmap.Create;
  SystemImageList.GetBitmap(index, bitmap);
end;
