[Lazarus] Project conversion Delphi -> FreePascal: success!

[Darius Blaszyk]

Hi Birger,

The list is definitely of interest to me and others! If possible please create patches and add them to the bug tracker. This will help not only future conversions but "ordinary" projects as well.

Regards, Darius

Also all contributors to wiki pages, newsgroups and forums: thanks! Even the smallest pages or postings contained useful information and are a valuable source of information.

It is intended for 2-Dimensional and 3-Dimensional geotechnical analysis of deformation and stability of soil structures, as well as groundwater and heat flow, in geo-engineering applications such as excavation, foundations, embankments and tunnels. (so this is a result viewer, the actual calculations are performed with another application).

During conversion I encountered lots of small issues (Unicode, OpenGL, images with scanline manipulation, generics, anonymous methods, class constants and functions, MDI forms, treeview with custom drawing, Steema TChart, custom controls and more). For most of the encountered issues I created a list with their solution, I'll try to clean it up and see if I can post it somewhere because it might also be helpful for others.
