For instance, I would like to change the text of every Edit.

Code: Pascal  [Select][+][-]
  1. AllEdits.Text := 'The same text';

Yes, you can loop all controls owned by the form:
Code: Pascal  [Select][+][-]
  1.   for i:=0 to Form1.ControlCount-1 do
  2.     if Form1.Controls[i] is TEdit then
  3.       TEdit(Form1.Controls[i]).Text:='new text';
Lazarus 2.1.0 r63881 FPC 3.3.1 r40507 x86_64-linux-qt Chakra, Qt 4.8.7/5.13.2, Plasma 5.17.3
Lazarus 1.8.2 r57369 FPC 3.0.4 i386-win32-win32/win64 Wine 3.21
