MSEide + MSEgui

Pascal Cross Platform GUI Development System

Version 3.8

MSEide is a Rapid Application Development IDE for platform independent rich GUI applications in the Pascal language.
It comes with its own GUI toolkit called
MSEgui, which ensures programs are portable.
MSEgui has identical look and feel on all supported platforms, the look of the widgets is highly configurable.
The widgetset library is completely written in Pascal and links directly to xlib on Linux and to gdi32 on win32.
MSEgui includes sophisticated DB-access components and DB-aware widgets.
Main goal of development is to provide a
handy, stable and very productive tool for professionals.
MSEide+MSEgui currently runs on i386-linux, i386-win32, x84_64-linux, x86_64-freebsd and arm-linux.


IDE is under GPL, library under modified LGPL like Free Pascal RTL.
