Added MessageBox for error report. 31 Jul 2000. Added the macros GTMENUITEM_USERDATA and GTMENU_USERDATA. 19 Aug 2000. Added functions and procedures with array of const. For use with fpc 1.0. They are in systemvartags. 11 Nov 2002. Added the defines use_amiga_smartlink and use_auto_openlib. 13 Jan 2003. Update for AmigaOS 3.9. Changed startup code for the unit. 01 Feb 2003. Changed integer > smallint, cardinal > longword. 09 Feb 2003. nils.sjoholm@mailbox.swipnet.se } {$I useamigasmartlink.inc} {$ifdef use_amiga_smartlink} {$smartlink on} {$endif use_amiga_smartlink} unit gadtools; INTERFACE uses exec, intuition, graphics, utility; {------------------------------------------------------------------------} { The kinds (almost classes) of gadgets in the toolkit.
