I thinks what your specific documentation are too much general, and a wiki list with several exemples is better.
I begin to convert a little project from DELPHI5 (or DELPHI7) to LAZARUS , but I uses several FREE components (download from TORRY.NET) , as DsfancyButton , GradBtnH , LsFileView28 , and PROLIB18
MANY PROBLEMS :
1) add {$ASMMODE INTEL} because small ASM code with "MOV EAX,ax"
2) type TTextStyle unknown
3) uses WinTypes, WinProcs ==> convert to USES WINDOWS
4) DBTables does not exist in LAZARUS : replace with what ??????
5) several TCreateParams in ERROR !! ===> add USES LCLType
6) several SWITCHS unknown : $SAFEDIVIDE , $L , $Y , $OBJEXPORTALL
7) problem with Ressource File ProConst.R16 in PROLIB18
function SysUtils.GetDiskFreeSpaceEX does not exists ==> you have to built a function with GetDriveIDFromLetter() , DiskSize , DiskFree
9) property CTL3D and ParentCTL3D give me 3 errors : not Published , not Override , READ attempted .... I do not understand why ???
... and so on ....
Can you begin a document with all samples post on the forum ?
Thanks !
