There are several properties where this feature would be welcome, eg
tcustomedit.text, tcustomcheckbox.checked, but you can use the following
workaround when necessary:
type
tcustomeditfriend = class(tcustomedit);
...
tcustomeditfriend(edit).edit := 'value';
I agree... And if you are going to use it often, create a local
variable of the 'friend' class so you only need to cast once.
Not a good idea if you have inheritance:
twincontrol
control: twincontrolfriend
tcustomedit
control: tcustomeditfriend
...
tcustomeditfriend.getcontrol
begin
result := inherited control as tcustomeditfriend; // problem here
end;
I write many cross compiler (FPC and Delphi) code and keep breaking
the builds under Delphi due to the differences between LCL and VCL.
Yup. This is exactly my headackes. Cross FPC x Delphi and VCL x LCL
code. Anyway both fpc and lazarus team are doing an exceptional job
regarding compatibility.
