Accessing to frReport component by code

[essence-ciel]

Hello,
Sorry for my bad English.

I'm looking to access frReport components programmatically from a Lazarus form.

I started with this code:

Code: Pascal  [Select][+][-]

1. for I := 0 to frReport1.ComponentCount -1 do
2.       if (frReport1.Components[I] is TGroupHeader) then
3.             frReport1.GroupHeader1.Visible := CheckBox3.Checked;  

   

But it's impossible to access frReport GroupHeader and display/hide the frReport GroupHeader. Ditto for changing the color of the associated Memo.

How can I retrieve the component, the index of it and modify it by code, please?

Windows 11, Lazarus 3.4, Sqlite 3.46.1
