Check attached file for example package.

What I'm trying to do is to add own custom option page to IDE options
dialog via package. Unfortunately this requires inclusion of ide
package as a requirement. Normally you can't use it for design
packages and trying to install a package which does have it as
requirement shows user a error dialog.

See Martin Friebe's explanation in my bug report at
http://bugs.freepascal.org/view.php?id=24455.

My package needs to access environment options and IDE menus.

See this code snippet:
Code: [Select]procedure THistoryOptionsFrame.WriteSettings(AOptions:
TAbstractIDEOptions);
Var
  EnvOptions : TEnvironmentOptions;
begin
  EnvOptions := TEnvironmentOptions(AOptions);
  If Assigned(EnvOptions) Then Begin

    if rfFiles in FRecentFlagsSet then Begin
      EnvOptions.RecentOpenFiles.Clear;
      MainIDE.SetRecentFilesMenu;
    end;

    if rfProjects in FRecentFlagsSet then Begin
      EnvOptions.RecentProjectFiles.Clear;
      MainIDE.SetRecentProjectFilesMenu;
    end;

    if rfPackage in FRecentFlagsSet then Begin
      EnvOptions.RecentPackageFiles.Clear;
      itmPkgOpenRecent.Clear;
      itmPkgOpenRecent.Enabled := False;
    end;

  end;
end;

So IDEIntf package needs to be modified somehow to allow this kind of
usage. But how?

The Jedi (jcf2) package does that.

Sorry it is about adding an option, or getting EnvironmentOpts?

What do you try to do with recent file entries?

What is the intended feature (as in seen by the user)?

BTW: Even if the ide package would be allowed for design, it would not
work the way you want.

- All packages, that are used by the IDE (includeng yours) are build
before the IDE itself is compiled. (They must be in order to be used)

- So at the time, where your package is build, the IDE sources have
not yet been compiled. They can not be used.

It may have worked in your experiments. But it may be that the package
was build with old ppu files, because the IDE sources were
unchanged... Or not detected to be changed...

Doing both, adding option and modifying EnvironmentOpts when user
selects different commands.

Clearing up all recent files (project and package) and maybe history
lists.

I recommend to ask on the mail list as well. I do not know the IDEIntf
itself that well. You may get additional feedback on the mail list.
