xulrunner and java

2010-01-06T15:22:13Z

Hi,
I'd like to create a framework to use xulrunner as the view of a java
application.
The idea of the framework is :
- install xulrunner if necessary (So that the application based on the
framework will run on any plateform, without the need of a pre installed
xulrunner)
- embed a web server like jetty (To be abble to comunicate from a xul

Dynamic nodes insertion & rendering issue (scrollbar)

2010-01-06T13:34:45Z

Hi all,
I'm inserting dynamically elements into my xul document with JQuery,
and it's working quite well.
Quite well because if the content is bigger than the container height,
the renderer don't show a scrollbar.
1. I load an iframe with an empty (almost) xul document
<?xml version="1.0" encoding="iso-8859-1"?>

Problem solved.
I actually had the finger on it: the dll was the problem.
If other people have this kind of problem here is what worked for me:
Just set the Visual Studio project to statically link runtime libraries (/MT
option): under C/C++ project settings, by default "Multithreaded library
(/MD)" is selected. Set it to Mutithreaded (/MT) only. This statically links

Hello,
I am new to XUL application development, and by reading a few tutorials I
now have a working application using an XPCOM component. I tested the
application under different windows XP environments, and could test the
component, but when trying with a windows 2000 version, I got the following
error:

Ipc or message back to js/xpcom from an external process

2009-12-30T04:49:34Z

Hi Guys,
Is there a way to get the ipc or a simple message from external
process to the js/xpcom app? Rightnow, I am relying on file io - which
is inefficeint.
Searching around, I found some pointers from 2007 - did anything
change or added for the inter process communication - either ipc/
socket?
I have something like below.

Saving preferences in a editable tree

2009-12-29T09:26:10Z

I am trying to implement an editable tree in which I am trying save
the preference string every time the user makes a change to the tree
using the 'onsynctopreference' event handler.
However, when I remove an element from the tree, this event handler
doesn't get called and I am manually saving the preference string.

Time permitting, will try and reproduce the problem in a small sample.
Real code is better than pseudo code.

Glad it is working finally. If you want to know why it didn't work,
share the pseudo code, might get some pointers.

nope.
I'm using setInterval.
Tried creating and sending a mousemove event and that din't work.
Finally, added an additional invalidate() to the callback (the
invalidate[Cell,Row,Range] were inside a function that was called from
the callback) and that seems to have solved the problem although I
don't understand why it works now and why it din't work earlier.

Does single invalidateRow work ok - w/o setTimeout? Explicitly calling
invalidateRow?
If above is true, try setInterval - which is slight different
implementation. If single invalidateRow itself is not working then you
have a different issue to deal with.
On the other question, I just checked on the threads, I don't think

Are you suggesting to remove the tree and insert it back? That sounds
very inefficient.
The tree data is maintained outside of the DOM by an object
implementing nsITreeView.
That is my question. The invalidate method on the tree's box object is
not forcing a redraw.
Yes, but again the invalidateRange and invalidateRow methods are not

This might work for you.

Just redraw the complete tree every 5secs. If there are lot of nodes
that you need to worry about, then maintain a cache which have the
value changed and only remove /redraw them.
