Actually, the problem with Windows API only arises in 32-bit Windows because there are multiple calling conventions in that case and the one needed to invoke Windows API functions is generally different from the one a Fortran compiler uses. This problem does not exist in 64-bit Windows because there is only one calling convention there. In fact, the problem could be overcome in 32-bit Windows with C interoperability but the vendors have not chosen to make that a workable solution. Now, if cross-platform means also to other platforms than Windows, then it goes without saying that extensive usage of Windows API functions is a really bad idea. -- write(*,*) transfer((/17.392111325966148d0,6.5794487871554595D-85, & 6.0134700243160014d-154/),(/'x'/)); end

IIRC Lahey compilers come with an introductory version of Winteracter. That is a professional, cross platform product. Silverfrost FTN95 comes with its own gigantic runtime library. It essentially handles the GUI by sending character strings to a terminal driver. There are some low cost / free solutions. DISLIN has widgets for GUI, but I've not used that package. JAPI uses JAVA but is no longer being developed. GrWin is windows sepcific but supports a large number of languages. There is WxWidgets but it is Windows specific and does not have Fortran interfaces. > If you have a Fortran program and want to give it a graphical user > interface, you are better off writing that in a language like Java or C++ > and making it communicate with your Fortran backend, e.g. using command > line arguments or, better yet, files.

On Win32 I sometimes create a Fortran DLL and attach its functions to Excel OR its subroutines to VBA or Delphi. It also depends on the libraries available with your compiler. You can do fairly low level, C style Windows GUI programming in the DVF/CVF/IVF family. Or there are some simplified calls like MessageBox or QuickWin. --- Elliot

If it helps, I have posted some notes on using DISLIN to make a GUI for Fortran. DISLIN provides only a limited selection of widgets, but it has the advantage that it works on Windows (R) and Linux. http://www.star.le.ac.uk/~cgp/dislinGUI.html -- Clive Page

WxWidgets supports several platforms other than Windows but it is C++ specific with bindings for many languages (but Fortran is not one): http://en.wikipedia.org/wiki/WxWidgets Lynn
From: steve on 5 Jul 2010 19:33 > There is WxWidgets but it is Windows specific You may want to check the wxwidget home page before making this statement. "wxWidgets is a C++ library that lets developers create applications for Windows, OS X, Linux and UNIX on 32-bit and 64-bit architectures as well as several mobile platforms including Windows Mobile, iPhone SDK and embedded GTK+." -- steve
