Couple of years ago we released a wxWidgets Form designer for Borland C++ Builder
. Last week we released a similar Form Designer for Delphi.
wxForms for Delphi is an integrated form designer plugin for Borland/CodeGear Delphi and a Pascal wrapper for wxWidgets that helps you to create cross platform applications for Windows and Mac OSX using single source base.
wxForms code from Delphi can be compiled in Mac OSX without much change using FreePascal/Lazarus.
wxForms allows you to use all of Delphi's powerful Form Designer/ Editor features (Form Alignment, Object inspector, Component Palette etc ) to quickly create Cross platform applications. Components can be easily customized by modifying their properties in the object inspector.
