#region equivalent in C++Builder? Similar way to group code?

Question

I was wondering if there is an equivalent to Visual Studio's #regions in RAD Studio.

We use Delphi and C++builder IDEs where I work and I would love to be able to use something like regions.

My coworkers and I have yet to find an equivalent way of grouping code... do you know of any?

Answer 1

You can apply a special {$REGION 'Region Name'} directive to mark a "named" collapsible regions in the code editor.

To mark code as a region, surround it with the REGION and ENDREGION directives. You may include a caption that will be displayed when the code is folded and hidden.

Here's an exampe of the two (nested) regions:

{$REGION 'Iterate Panels'}
for j := 0 to StatusBar1.Panels.Count - 1 do
begin
  x := x + StatusBar1.Panels[j].Width;
  {$REGION 'Inner if Region'}
  if mpt.X < x then
  begin
    panel := j;
    Break;
  end;
  {$ENDREGION}
end;
{$ENDREGION}

To fold or unfold a region, click on the [+] (if expanded) or [-] (if collapsed) marker left to the $region directive. This will look:
