Computing: Free Pascal Programming

My Free Pascal GUI Applications.


About the applications on this page.
All downloads on this page are provided free of charge and without any warranty of any kind. You may use them as you like, but if you do so, it's entirely on your own risk! Please, have a look at this Web site's disclaimer for further details.
Also note, that I myself am not really a confirmed Windows programmer. I never made computer science studies and, even if I wrote my first computer programs more than 40(!) years ago, concerning GUI programs, I only began to develop graphical desktop applications in 2016/2017. Thus, the source code on this side is nothing like perfect, sometimes (especially in the older applications) perhaps even "just as you shouldn't do", without the knowledge of all the possibilities, that Lazarus/Free Pascal offers and how to best implement them, also without real care about file size and resources used. On the other side, I think that you can find here lots of inventive and interesting stuff, concerning all kinds of domains. I also could imagine, that people for whom, like for me, informatics is primarily fun, may consider the code on this site, as one between other possibilities to realize a given application, to modify it in order to adapt it to their own needs, to extend the program or to find ideas to realize their own applications.
The programs on this page are GUI (graphical user interface) based applications, running in a desktop window. The executables, available for free download, have been compiled for a Windows 64bit platform. The sources of most of them should be suitable without greater modifications to create binaries for Windows 32bit, Linux or Mac OS. Just recompile them on the platform, where you want to run them. If you just want to run the application, use the icon in the Exec column to download the executable (if it needs supplementary files such as data, these are normally packed with the executable in the .zip download archive). If you are interested in the code or want to recompile the program (to adapt it to your needs or to use it on a different platform), use the icon in the Source column (the download file will be a .zip archive with all relevant files, NOT including any executables). To view the description of the application (including Free Pascal features and screenshots), click the program name in the Program column.

You can use the Search feature in the Help menu to limit the list to a given domain, to group the applications by functionality, to search for an application by specific keywords, or to search for sources, that include a specific Free Pascal feature. You also find there a link, starting a slideshow with the screenshots of all my Free Pascal GUI applications.
