Summary0025870: TCustomButton.Click is protected
DescriptionTCustomButton.Click is protected in the LCL.
In the VCL, TCustomButton.Click is public.

Seeing that TButton.Click just calls inherited, I think that the best solution is to make TCustomButton.Click public and remove the TButton.Click
Steps To Reproduce1. Drop button on form (Button1).
2. Create function:

Function TForm1.GetCustomButton : TCustomButton;


3. Create OnShow event:

Procedure TForm1.OnShow(Sender : TObject)
  B : TCustomButton;
  if Assigned(B) then

Fails in LCL, works in Delphi

The same change was required for TCustomBitBtn and TTICustomButton but I don't see any problem with it.

I don't know. It is up to you.
This is somewhere between a bug fix and a feature.

@Juha we must discuss such patches on mailing list (and other issues which I marked as possible merging). This is not feature (but changes interface section), but bug (delphi compatibile).
While agreement is that only bug fixes goes to stable fixes this should go there IMO. Please add it to the fixes by yourself.
