Cumulus

About

This is a Delphi port of the infamous "WP-Cumulus" WordPress plugin, originally an ActionScript flash project written by Roy Tanck.

It allows you to load your data from an XML document, displaying contained tags and/or categories by placing them on a rotating sphere, and allowing these tags to be clicked.

Usage

procedure TfrmCumulus.FormShow(Sender: TObject);
var
  MyXML : IXMLDocument;
begin
  TagCloud := TTagCloud.Create(Self);
  TagCloud.Parent := Self;
  TagCloud.OnNavigateToURL := NavigateToURLHandler;

  TagCloud.Align := alClient;

  TagCloud.TagsColor := $ffffff;
  TagCloud.BackgroundColor := $333333;
  TagCloud.TransparentMode := False;
  TagCloud.RotationSpeed := 100;
  TagCloud.EvenlyDistributedTags := True;
  TagCloud.DisplayMode := dmTags;

  try
    MyXML := LoadXMLDocument('tagcloud.xml');
    TagCloud.Initialize(MyXML);
  except
    ShowMessage('Failed while attempting to load XML file.');
  end;
end;

Caveat

Having entities defined in XML files should be avoided. Since while they are being loaded, they will cause an exception to be raised of class type EDOMParseError, with the message Reference to undefined entity xyz.
