Re: [Lazarus] TPageControl OnChange calling issue

If the existing functionality differs from Delphi, i say to keep the existing functionality as the default. After all what is more important? Breaking existing Lazarus users' code or potentially having a Delphi code migration become slightly harder because a project will need to change a property

Re: [Lazarus] TPageControl OnChange calling issue

Then there's the problem with what behavior should be default. If we say LCL is VCL compatible then it is clear, but the more I think about it the more I feel Delphi behavior is just strange. Probably thinking is not appropriate here... The same problem is with TComboBox Style=csDropDownList.

Re: [Lazarus] TPageControl OnChange calling issue

Delphi's developers faced exactly the same dilemma with respect to Windows' behavior. Some of the standard behavior triggering events did not make much sense and they had to decide to keep it as it was or define an improvement. For the most part they kept it as it was. These are not easy
