I've committed the ported Gecko source to CCR Subversion and created a wiki page:

http://wiki.lazarus.freepascal.org/GeckoPort

Thanks.

I've expanded the GeckoPort wiki topic:

http://wiki.lazarus.freepascal.org/GeckoPort

I also committed an updated version of the GeckoPort package:

- Replaced BrowseWin sample app with ChromeWin app that works better since it implements all required interfaces.

- Several changes to GeckoChromeWindow.pas

- Now assumes new ObjC-based Cocoa widgetset instead of old PasCocoa-based Cocoa widgetset. The new widgetset does not work as well with Gecko as the old widgetset did (nothing displayed in ChromeWin window), but it's the future so GeckoPort is now using it even though it's very new.

Note that several Linux users have confirmed that an exception is raised in libmozjs.so when libxul.so's XRE_InitEmbedding function is called from nsXRE.pas. If anyone has any ideas on what's wrong, please post them here.

Thanks.

I don't know what those are.

Maybe you could take a look at TGeckoBrowserListener.OnStateChange?

Thanks.

Hi Phil, thanks for reply,

I tried to use OnStateChange, but this event is not accessible from the component TGeckoBrowser (I use the SVN version and makes regular updates). Are you a example ?

Just as I had not found a method GeckoBrowser.Stop/Abort

Sorry, you're beyond my understanding of this. You'll probably need to spend some time with the ported source.

Thanks.

Maybe once you've reached a point where you think you've added most of what you want changed, we can look at merging them into the Lazarus CCR. It appears that you're using Delphi so just remember that changes need to be FPC / Lazarus compatible.

Also, normally you don't post compiled files like .dcu to a Subversion site.

Thanks.

On WindowsXP with FireFox 3.0 i have error on init GeckoBrowser.
I had add code in unit nsInit
function GRE_GetGREPathWithProperties and now all OK.
Code: [Select]
var
  LenS: DWORD;   
  S, sValue: AnsiString; 
...

...
  sValue := 'SOFTWARE\Mozilla\Mozilla Firefox';
  if RegOpenKeyEx(HKEY_LOCAL_MACHINE, PAnsiChar(sValue), 0,
                  KEY_QUERY_VALUE, hRegKey) = ERROR_SUCCESS then
  begin
    SetLength(S, buflen);
    LenS := buflen;
    ok := RegQueryValueExA(hRegKey, PAnsiChar('CurrentVersion'), nil, nil,
        @S[1], @LenS) = ERROR_SUCCESS;
    RegCloseKey(hRegKey);
    if ok then
      begin
        S := PAnsiChar(S);
        sValue := sValue + '\' + S + '\Main';
        LenS := buflen;
        ok := (RegOpenKeyEx(HKEY_LOCAL_MACHINE, PAnsiChar(sValue), 0,
                  KEY_QUERY_VALUE, hRegKey) = ERROR_SUCCESS) and
              (RegQueryValueExA(hRegKey, PAnsiChar('Install Directory'), nil, nil,
                  PByte(buf), @LenS) = ERROR_SUCCESS);
        RegCloseKey(hRegKey);
        if ok then
          begin
            NS_StrLCat(Buf, '\xpcom.dll', BufLen);
            Result := NS_OK;
            Exit;
          end;
      end;
  end;

Thanks. Where did you insert that code in GRE_GetGREPathWithProperties?

The original code I ported did not work with the current version of Firefox, hence why I hardwired the location if the function failed.

In my testing it seems like it stopped working with my Firefox DLL's following a point upgrade, but I haven't tested with the latest point upgrade. What version of Firefox are you using?

If you're planning to distribute an app that uses your user's Firefox DLL's, that might be risky if what I observed is true. By distributing your own xulrunner DLL's below your app, everyone will be using a version that you tested and is known to work correctly.

Thanks.

I insert the code in the end of function before last line
Code: [Select]
Result := NS_ERROR_FAILURE;
Firefox version 3.0.
Now update to 3.5.7 and my app run OK.

If I have time, I'll test here and maybe introduce your changes in the SVN version, although I might check first to see if xulrunner is installed below the app and, if not, then use your approach to use the installed Firefox .dll's. That way if somebody wants to use a local copy of xulrunner, they don't have to change the code to prevent it from using Firefox dll's.

Also, maybe I'll introduce some of the new events and properties (see above).

We haven't been able to get this to work on Linux or OS X yet, so Gecko SDK is not real useful to me yet.

Thanks.

I get a RunError(229) at line
1709 baseWin.Repaint(True);   
of GeckoBrowser while trying to run GBrowser app.
Can anyone tell what this means?

I also failed to run ChromeWin with the same error.

xulrunner is a subfolder of SampleApp folder.
