unable to write in textbox/text area

2009-12-11T03:23:35Z

I have embedded Xulrunner into my native application. The webpage
opens up in xulrunner browser and renders the html page correctly.
However the browser is not letting me to enter text into the text
fields or text area. Is there anything specific required for letting
the user enter text.

You could try looking through nsContentUtils.h/cpp for places that push
JSContexts and do likewise...

Sorry, I'm not going to write the code right now.

I don't believe there's a good way to do this in C++. Certainly not if
you plan to modify the rules.

Hi Boris,
Thank you for your answer. I have to tell that I'm not familiar with
things like JSContext, nsIJSContextStack yet. I tried to push current
JSContext on the stack, but no success. Could you please provide some
advice more in detail please? I don't know how to retrieve document's
JSContext. The Gecko version is lower then 1.9.2 unfortunately.

What I'm trying to do is to retrieve all stylesheets, change it and
set this new value. I just want to edit the document's CSS. If there's
some better way to achieve this, please let me know. Probably I didn't
choose the right way.

Thank you!

Re: Does anyone know the work-around for this gtkmozembed focus issue?

2009-12-09T20:25:06Z

I just found the workaround method:

In widget/src/gtk2/nsWindow.cpp, change the following line (line No. 2887
for 1.9.1):
if (!gFocusWindow && containerWindow) {
to
if (containerWindow) {

I also found another bug in 1.9.2 (
https://bugzilla.mozilla.org/show_bug.cgi?id=533245) that clicking a
focusable element in an embedded browser window can't make the element
focused. I also found the workaround (the above workaround is not needed),
please see in the bug report if you are interested.

Xianzhu

How to Embed Intro? ( Any help would be greatly appreciated)

2009-12-09T12:59:52Z

Hey All,

I'm needing assistance getting started. I've looked at Mozilla docs
which I will continue to do and am grateful to have, however from an SDK
API standpoint, I was hoping to find something more like.

To Embed do the following:

1. Download xulrunner-XXX or Firefox-XXX source (whats the difference?)
a) To build for embedding purposes, .mozconfig should be?
b) How to install ( e.g. make install or equiv which puts libs?)

2. When compiling include:
a) Which switches (e.g. -DMOZILLA_INTERNAL_API -DMOZ_XUL )
b) Which headers to include ( normally, but I think I got this )

3. When Linking:
a) Which libs (e.g. -lxul , but I don't see a libxul.a or dylib)

4. Sample/minimal Hello World (helpful, but I can use the more
complicated apps that embed mozilla, which makes it more complicated to
focus on what is necessary. But now I'm using Camino as a guide )

5. And Any gotchas would be nice, but I live without.

Instead what I get at times when I thinking I'm getting somewhere, is a
document that read "Warning: This document is out of date. You should
instead build XULRunner and use it for all new embedding..." as found in
document titled "Roll your own browser - An embedding HowTo", which
appeared to be what I wanted, as apposed to the XUL doc which wants to
write XUL script, which is not the kind of embedding I want, etc.

Basically, I desire a C/C++ Unix/X11 gecko embed, without using say
MozEmbed Gtk or the like, which 0on't expose all the API features.

Any help would be greatly appreciated, answers or references to valid
docs that have them, meanwhile I'll be poking around still. Many Thanks!

Re: nsIWebBrowser and GtkMozEmbed

2009-12-08T06:29:56Z

Ok, found the problem. Seems there's an additional step to bind the glue
correctly.

I couldn't find any documentation on this. Aside from the
GTKEmbedGlueStartup() call, you also need to call
GTKEmbedGlueStartupInternal().

Embedding Gecko/XULRunner for ARM Environment.

2009-12-08T03:07:29Z

Hi,

Can I build Gecko/XULRunner for ARM Environment? If yes, can anybody
let me know the process in detail?

The following are the contents of the "mozconfig" file that I'm using
-
------------------------------------------------------------------------------------------------------
CROSS_COMPILE=1
mk_add_options MOZ_CO_PROJECT=xulrunner
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/obj-xulrunner

ac_add_options --disable-javaxpcom
# with Windows XP support
# ac_add_options --with-windows-version=600
--host=i686
--target=arm
-------------------------------------------------------------------------------------------------------

But, after I build the Mozilla Sources and then go to the Directory
"obj-xulrunner/embedding/config/" and run make there, it comes up with
the following error -
----------------------------------------------------------------------------------------------------------------------
d:/Projects/mozilla-1.9.2/obj-xulrunner/config/nsinstall -t ../../dist/
bin/mfcem
bed.exe ../../dist/Embed
nsinstall: ..\..\dist\bin\mfcembed.exe: No such file or directory

Somebody please help, as I stand in a crossroad, from where I can't
move further.

You're calling this from C++, and presumably without JS on the stack,
and therefore end up failing the security check GetCSSRules does. Had
you checked the return value you would have known at least that you were
failing a security check...

You may be able to work around this by pushing the document's JSContext
on the JS context stack, though if that context can be running script in
your situation and if that script is not same-origin with the stylesheet
(or heck, if the document is not same-origin with the stylesheet) you
won't get the rules.

If this is Gecko 1.9.2 or later, you can probably use
pushContextPrincipal on the security manager to push a new jscontext and
the stylesheet's principal; that would guarantee things to work.

Getting the CSS rules collection

2009-12-07T09:15:00Z

Hi,

I'm trying to get the collection of CSS rules of certain document.
Following is the source code I try to use to retrieve those rules.

nsCOMPtr<nsIInterfaceRequestor> requestor;
this->GetInterfaceRequestor(getter_AddRefs(requestor));
nsCOMPtr<nsIDOMDocument> document = do_GetInterface(requestor);

nsCOMPtr<nsIDOMDocumentStyle> doc = do_QueryInterface(document);
if (doc)
{
nsCOMPtr<nsIDOMStyleSheetList> sheets;
nsresult rv = doc->GetStyleSheets(getter_AddRefs(sheets));

PRUint32 length;
sheets->GetLength(&length);
for (PRUint32 i = 0; i < length; ++i)
{
nsCOMPtr<nsIDOMStyleSheet> sheet;
sheets->Item(i, getter_AddRefs(sheet));
nsCOMPtr<nsIDOMCSSStyleSheet> cssSheet = do_QueryInterface(sheet);

if (cssSheet)
{
nsCOMPtr<nsIDOMCSSRuleList> rules;
cssSheet->GetCssRules(getter_AddRefs(rules));

if (rules)//this will be false!!!
{
PRUint32 rulesLength;
rv = rules->GetLength(&rulesLength);

for (PRUint32 j = 0; j < rulesLength; j++)
{
nsCOMPtr<nsIDOMCSSRule> rule;
rules->Item(j, getter_AddRefs(rule));

nsAutoString ruleText;
rule->GetCssText(ruleText);
}
}
}
}
}

it doesn't pass the 'if (rules)' condition and I wasn't able to find
out what's wrong. If you were able to help, it would be really great.
Thank you in advance!

martin

nsIWebBrowser and GtkMozEmbed

2009-12-07T07:27:01Z

Hey Guys,

Running into a runtime issue with GtkMozEmbed. When I call
gtk_moz_embed_get_nsIWebBrowser, I'm getting a segfault with a stack
trace that's pointing to NULL.

(gdb) bt
#0 0x00000000 in ?? ()
#1 0x0807b91f in mozilla_purge_history (embed=0x80d5810 [GtkMozEmbed],
full_purge=1) at mozilla.c:292
#2 0x08066e9d in moz_embed_uri_open (moz_embed=0x80d5810 [GtkMozEmbed],
uri=
0x87522d0 "http://localhost/main_menu.php") at moz_embed.c:336

290 if (embed != NULL && GTK_IS_MOZ_EMBED (embed)) {
291 gtk_moz_embed_get_nsIWebBrowser (GTK_MOZ_EMBED(embed),
292 &browser);
293 //getter_AddRefs(browser));
294 }

I've tried with getter_AddRefs based on browser being declared as
nsCOMPtr<nsIWebBrowser> browser;

And above with browser declared as
nsIWebBrowser *browser;

Behaves the same way in both instances. This would seem to be a runtime
issue. I'm using XPCOM_GLUE and attempted to follow the standalone glue
model.

Does anyone have any tips. I can't see what could be wrong. I've
verified that the 'embed' parameter is valid and is a GtkMozEmbed
object. I can follow the stack through some of the marshalling code with
GDB.

If I step into the call to gtk_moz_emed_get_nsIWebBrowser, I can see it
going into
GType gtk_moz_embed_get_type(void). The static GType varaible in there
is not 0, so it steps down to the return part of the function. Stepping
on the return call takes me to
GTypeInstance* g_type_check_instance_cast (GTypeInstance *type_instance,
GType iface_type).
In there I can see that type_instance is GtkMozEmbed

(gdb) print type_instance
$1 = 0x80d5810 [GtkMozEmbed]

In the gtype.c code it performs a few checks and then if check variable
is TRUE, it returns type_instance. This the point where it fails and I
get a segfault in 0x0000000

This to me points to some sort of runtime late binding issue.

Does anyone know the work-around for this gtkmozembed focus issue?

2009-12-06T20:58:15Z

Hi,

We encountered a bug of gtkmozembed that it can't correctly transfer
focus between two embedded browsers in one window. We submitted the
bug report (https://bugzilla.mozilla.org/show_bug.cgi?id=490447) half
a year ago, but we still haven't the solution. I have tried to
discover the cause, but the focus logic is too complex to me.

Has anyone encountered the same issue, and knows the work-around?

Thanks,

download UI

2009-12-04T12:27:16Z

I am embedding xulrunner in Eclipse SWT browser. When download a file, the
progress window is display and it is not resizable. How do I make it
resizable like in Firefox?

Also, when the download completes, I got the download complete alert box
popup ( not sliding out from bottom right corner like Firefox 3.5.x ), and
the alert box is big and not able to resize either.

Would appreciate any help!

I'm using NS_DECL_ISUPPORTS in the header, but as you sais, I didn't
implement these methods.

I want to test if webprogresslistener is that I need.
I want to execute some javascript in the html page after load it
completly, and if is it possible, send with javascript a message to my
gtk embedded browser application to close the browser and destroy the
gtk window.

What is the best way to do this?

Indeed, we removed NS_STATIC_CAST and recommend that people just use
static_cast<type>() directly.

This code is definitely incorrect. You've declared a
nsCOMPtr<MyBrowserProgressListener> ml; but you haven't actually *created* a
MyBrowserProgressListener. Did you perhaps mean:

nsCOMPtr<MyBrowserProgressListener> ml = new MyBrowserProgresListener();

Then you try to get a weak reference to your listener. I'm not sure why
you're trying to do this, but your MyBrowserProgressListener class doesn't
implement nsISupportsWeakReference and so do_GetWeakReference will
undoubtedly fail, leaving `listener` null. The typical and recommended way
to implement nsISupportsWeakReference is to inherit from
nsSupportsWeakReference and make sure your QueryInterface implementation

With all the to'ing and fro'ing I ended up forgetting to make sure that
the xpcomglue linking was passed after the .o files.

Now I've got a proper working reference, I'll see if I can get my main

I've updated the http://slaine.org/files/testgtkembed.tar.bz2 file with
the tweak so it should be usable if anyones interested in playing with it.

AddWebBrowserListener fails (NS_ERROR_INVALID_POINTER)

2009-12-02T04:01:54Z

Hi,

I created a C++ class called MyBrowserProgressListener. This class
implements the nsIWebProgressListener interface. When I run the application
the AddWebBrowserListener fails. I returns 0x80004003
(NS_ERROR_INVALID_POINTER)

I defined the NS_STATIC_CAST in main.cpp code because isn't defined in
nscore.h. [#define NS_STATIC_CAST(__type, __ptr) static_cast< __type
>(__ptr)]
I included the "nsIWeakReference.h" and "nsIWeakReferenceUtils.h" headers
because without them the compiler returns: do_GetWakReference was not
declared in this scope.

Issues migrating GtkMozEmbed app to gecko 1.9

2009-12-01T09:06:31Z

Hey Guys,

I've emailed about this before but the project never really went
anywhere. It's in full swing now and I'm not having much of a fun time.
Basically, we've got a Gtk application on Linux that's been using
GtkMozEmbed since pre Mozilla 1.0 days. It's used as a fullscreen
browser for the UI on a touchscreen device.

I'm currently porting from using FireFox 2.0 on an older Fedora Core
platform to FireFox 3.5.5(xulrunner 1.9.1) on Fedora12.

I'd like some pointers on how to build the TestGtkEmbed.cpp file outside
the scope of the xulrunner/ path. I think the compiler and linker
changes are the key to my problems, so if I could get that side of
things working properly then I'd have a good platform to figure out why
my code isn't working.

1) I've replicated the API calls from TestGtkEmbed.cpp for the new GRE
and XPCOMGlue changes
2) I've used the pkg_config --cflags and --libs values from
"mozilla-gtkmozembed-embedding", which gives me
pkg-config --libs mozilla-gtkmozembed-embedding
-L/usr/lib/xulrunner-sdk-1.9.1/lib -lxpcomglue -lplds4 -lplc4 -lnspr4
-lpthread -ldl
3) At runtime, I'm segfaulting in gtk_moz_embed_new()

Found xpcom path [/usr/lib/xulrunner-1.9.1/libxpcom.so]
Setting profile to [/home/glen]

Program received signal SIGSEGV, Segmentation fault.

How to close gtk window after execute all javascript code

2009-12-01T09:02:32Z

Hi,

I embedded Gecko in a GTK application. It opens pages containing javascript
code. For example, they have some timers and make changes after load the
page.

I wan't to close the gtk window when the page ends executing all.
I thought that I could close the window with "window.close()" javascript
function and get the event implementing niWebProgressListener interface or
other interface, but the "window.close()" javascript function doesn't close
the window because it's the main broser window.

How can I inform to gecko that a page has finished executing all and is
ready to be closed?

Firstly, sorry for repeat the same post many times, I thought there
was problems because the message didn't appear some time after send
it.
I resolve the javascript problem. I saw that nsIWebBrowserChrome is
the key.

Yes; you can either watch for pageshow events or onLocationChange
notifications, depending on how you want to handle anchor scrolling on
the same page.

Note that this won't limit itself to links; it'll include scripted
location sets, form submissions, etc. If you need to restrict
specifically to link clicks for some reason you might have to figure out
how to do that.

Re: notify when event handling is complete

Thanks Boris.

Is there a way for me to know if clicking a link, caused a NEW page load?

e.g. <a href="http://google.com">
google</a>.. when I click this link, is there a notifier that tells me that
a NEW page load occured?

So if the link click starts an animation that moves every 10ms after
that point.... when do you want to be notified?

There isn't one, since the concept of "complete" is not exactly
well-defined here.

notify when event handling is complete

2009-11-27T09:23:08Z

I am working on embedding Gecko..

Question: when a user clicks on a LINK (anchor node), I want to know when
the processing of the request is complete. i.e. if the link just updates the
existing page with content, then I would like to know when the update is
complete.. so that when I retrieve the DOM, I see the updated content..
Right now, I just sleep for a minute and then parse the DOM. Most of the
time this works, but I would like to know if there is a notifier that I
could use.

e.g. In the code below, clicking on "Populate", adds innerHTML to "div1"...
I want to be notified when the processing of clicking on anchor is done, so
that I can retrieve the DOM. I tried looking at the code but didn't see
anything that would do this. I saw nsIDocumentObserver::BeginLoad() and
EndLoad() and BeginUpdate() and EndUpdate()... Could someone point me to the
right direction.. thanks

<html>
<body>
<div id=div1>
</div>

<script>

function populate()
{
var div1 = document.getElementById('div1')

div1.innerHTML = "<b>POPULATED</b>"

}

</script>

<a href="javascript:populate()">Populate</a><br>
</body>

</html>

How to get X11 Window Id?

2009-11-26T05:57:21Z

Hi All,

Need to write an XPCOM which returns X11 window id for the current
window. The entire problem is to save window thumbnail to some file to
pass it to some external application (a window manager actually). So, to
identify the saved thumbnail I would like to name the file as winid.png.
Is it possible to do that in JavaScript or in C++?

Respectfully,
Michael

Problems with javascript in embedded browser

2009-11-26T02:50:04Z

I've a Linux C++ application with mozilla browser embedded.
The embedded browser shows the google page well.
I made a simple page with some javascript code, to do a test. The page has a
table with a text and the javascript changes the text with an image. If I
open the page with firefox it shows fine, but the embedded browser only
shows the text. Embedded browser supports javascript as firefox, in't it?
What's the problem?

Here is the source code:

<html>
<head><title>TESTING</title>
<script src="buildTable.js" type="text/javascript"></script>
</head>
<body bgColor="yellow" onload="buildTable();">
<table id="myTable" border="2" width="400" height="400"><tr><td><span>
TEXT </span></td</tr><table/>

</body>
</html>

// And this is the code of buildTable.js file:
function buildTable(){
var build = '<tr><td><img src="food020.jpg" width="100"
height="100"></img></td></tr>';
document.all.myTable.innerHTML=build;
}

I saw where is the problem, but now I've other problem. I downloaded
xulrunner1.9.1.4 and installed it following the instructions, but
Fedora installed an older version of xulrunner (1.0.15) in other path
(/usr/lib/xulrunner-1.9). I change the path in the code and now the
embedded browser appears. Thank you very much.

No, you'll need to actually debug the problem.
