Pascal Scripting: Support Classes Reference

Below is the list of support classes that can be used from within the Pascal script. There are also two support objects available: MainForm of type TMainForm and WizardForm of type TWizardForm and one special constant: crHand of type TControl.Cursor. Note: MainForm is only visible if WindowVisible is set to yes.

Note: you may find it useful to also refer to the Delphi Visual Component Library (VCL) Help files by Borland, since the classes below are mostly simple wrappers around the VCL classes Inno Setup uses internally. See http://info.borland.com/techpubs/delphi/ and ftp://ftp.borland.com/pub/delphi/techpubs/delphi3/d3cs.zip.
