So mache ich das zur Laufzeit:
Code:
type
TControlTrick = class(TControl) public property Font; end;
[...]
for i:=0 to frm.ComponentCount-1 do begin
if frm.Components[i] is TControl then begin
if TControlTrick(frm.Components[i]).Font.Name = OldFont then
TControlTrick(frm.Components[i]).Font.Name := NewFont;
end;
end;
