Problem migrating from 0.8.3 to 1.0 beta

2009-11-25T23:13:03Z

Hi there.

I try to migrate from 0.8.3 to the new 1.0 beta. I follow the instructions described here:

http://qooxdoo.org/documentation/1.0/migration_guide_from_08

But when I run ./generate migrate I get the following:

"Nothing to do. Your application is up to date!"

I've just replaced the old content in my Qooxdoo folder with the new, so I assume no paths need to be changed?

Thanks a lot! :)

generate all?

>From the qooxdoo doc:

> Just be aware (as mentioned on that page) that all of them need a generate.py build first in their respective directories.

I always wondered if there is there a reason why no single command
exists to generate *all* the example and demo code instead of having
to run generate.py in every directory.

Re: We just launched beta of the iRequest live webapp

2009-11-25T17:27:54Z

Hi, guys!

We added a http://irequestlive.com/posts/6 cool new feature that allows
importing songs from iTunes (by copy-pasting them from iTunes to browser).

We are planning on posting some code snippets sometime next week (mainly
focused on efficient rails <-> qooxdoo integration), but you can ask
question here, I'll be glad to answer.

By the way, Google Chrome seems to replace <Tab> characters with spaces on
paste. I wonder why they do that?

Cheers,
Gleb

Re: How to extend a class from which I need to access private variables (in the correct way...)

2009-11-25T15:57:25Z

here is my problem. I need to extend TabView.js in a very simple way, actually just to allow tabs to go either at the left (current behavior) or at the right of the tab bar. So what I did was extending TabView and adding the following function:

This code is almost identical to the add function in the original class. Now this worked quite well in development, but in production I realized that private variable access is strictly enforced via a scrambling of the variable names, so the build version of the application was totally failing. I know I can turn off this scrambling but I would prefer not to, just for this case. Besides, just copying that code and modifying it is not good (bad practice). I should be overriding a much smaller section of the code.

So my question is simple, how can I extend the class and still do what I need? Currently my workaround was to change all the private variables to protected ones in the base class. That works, but in long term that's not OK as i dont want to maintain patches against upstream version. I would rather cooperate now with upstream to know what can be done on this case. I am ready to provide patches etc, but I would like to find a way that's acceptable to the Qooxdoo base team (upstream) and my own needs. That could involve refactoring the code to make overriding specific methods more easier, if you are OK with that.

This is interesting. I _think_ you should be able to do it with a mixin, but I have a feeling that the generator is going to mess with variable obscuration too early for it to take effect. Hopefully I'm wrong. Give the following untested code a try. Create a mixin and add your addSpecial method to TabView rather than extending TabView with your own class.

qx.Mixin.define("custom.MTabView",
{
methods :
{
    addSpecial : function(page, right)
    {
      ...
    }
}
});

Then in your application, include this mixin before your first use of TabView:

qx.Class.include(qx.ui.tabview.TabView, custom.MTabView);

Now every time you instantiate a qx.ui.tabview.TabView object, it will have the addSpecial() method too.

Good luck! :-)

How to extend a class from which I need to access private variables (in the correct way...)

2009-11-25T15:14:22Z

Hi guys,

here is my problem. I need to extend TabView.js in a very simple way, actually just to allow tabs to go either at the left (current behavior) or at the right of the tab bar. So what I did was extending TabView and adding the following function:

        addSpecial: function(page, right)
        {
            if (qx.core.Variant.isSet("qx.debug", "on"))
            {
                if (!(page instanceof qx.ui.tabview.Page))
                {
                    throw new Error("Incompatible child for TabView: " + page);
                }
            }

            var button = page.getButton();
            var bar = this.getChildControl("bar");
            var pane = this.getChildControl("pane");

            // Exclude page
            page.exclude();

            // ******** Different code ************ //
            if (right)
            {
                bar.add(button);
            }
            else
            {
                bar.addBefore(button, this.spacer);
            }
            // ******** End of different code ************ //

            pane.add(page);

            // Register button
            this.__radioGroup.add(button);

            // Add state to page
            page.addState(this.__barPositionToState[this.getBarPosition()]);

            // Update states
            page.addState("lastTab");
            var children = this.getChildren();
            if (children[0] == page)
            {
                page.addState("firstTab");
            }
            else
            {
                children[children.length - 2].removeState("lastTab");
            }

            page.addListener("close", this._onPageClose, this);
        },

This code is almost identical to the add function in the original class. Now this worked quite well in development, but in production I realized that private variable access is strictly enforced via a scrambling of the variable names, so the build version of the application was totally failing. I know I can turn off this scrambling but I would prefer not to, just for this case. Besides, just copying that code and modifying it is not good (bad practice).

I am looking for suggestions on how it could work for both of us, is there an official policy on this maybe?

Looking forward to your reply,

Jean-Noel

PS: and to be honest I have not only TabView.js but also other classes from which I extend and suffering the same exact problem.

Re: Internet Explorer: "A script on this page slows down IE..." when quiting application

Sigh. Yet more IE speed issue. I imagine that your application is QUITE large if destruction is taking that incredibly long.

You might consider using the close() method and doing some of the destruction progressively using qx.ui.progressive.Progressive and its FunctionCaller renderer. An example of using that is in the demobrowser:

http://demo.qooxdoo.org/devel/demobrowser/index.html#progressive~ProgressiveLoader.html

Although this demo is showing Progressive and the FunctionCaller renderer being used as a progressive loader, it can just as easily be used as a progressive unloader. Your difficulty will be in figuring out what and in what order to destroy. That task, however, is left as an exercise for the reader. :-)

the bug is in ... 3110 ... I'm glad to contribute the renderer, to

Re: error with generator.py

[qooxdoo-devel] Context menu T,

This comes up from time to time on the board. Is it possible for some step in the "generate" script to detect a framework upgrade and perform the distclean step automagically?

Just a thought,

Gene

Maybe there is something I have to change in my conf files in order to use the HEAD version?

Hi Tobias,

the canvas cell renderer is really cool. Please file a bug for the
missing event (if possible with a patch). Maybe we can even include the
canvas renderer into the framework.

Best Fabian

BTW
The charts you are drawing right now could be easily implemented with
normal HTML but I guess you have fancier charts in mind :-)

Hello Burak,

We plan to have the API consistent among all 1.x releases. But as you sure
know, improving things means sometimes changing the API. But we always have
the old API available and working (at least we plan to).

Moving the 1.0 release to some later point is currently no option. There are
not only the io things "not perfect" in the framework. So waiting for all
stuff to be the way we like it could take some time (years).

The whole table is a point we need to discuss here in the team. We planed to
build a new table on the virtual widgets infrastructure which has not
happened jet. So we first need to get our plans and roadmap for the upcoming
year ready to tell you how much time we can invest in the "old" table. If
you think that renaming of the table namespaces are a good idea, you can
file a bug report but as i said, i don't know if we have time to fix it
soon.

The topic of remote models is sure on our list but in the context of data
binding. There is already a bug for that
(http://bugzilla.qooxdoo.org/show_bug.cgi?id=2993) which will be addressed
soon (at least I hope so).

Best,
Martin

Re: rpc in qooxdoo

Hello Burak,

I think you are making valid points for real business applications involving
sensitive data. However, I wonder how many times a javascript client will be
used for such applications. In the traditional HTML model, the client will
only expose data that the server feels safe enough to expose - all other
data remains on the (middleware) server. But I don't know enough about these
issues - the data I am dealing with (bibliographic data) is not really
sensitive - no need to encrypt anything except passwords.

What I would propose, however, concerning your SOAP contribution, is to
reorganize the contribution structure according to the new contribution
skeleton, i.e., separationg library code from demo application,. Also, I
would propose to put the backend in a dedicated directory (I use "services"
for the PHP and Python jsonrpc servers on the same level as the "source"
directory). I think this would make including and using your contrib much
easier.

Best,

Christian

i agree. i'd vote for postponing the 1.0 release for this reason, if

hi christian,

having authentication as part of the transport as a standard will let us
put the authentication implementation inside the core library -- saving
some developer time, thus lowering the cost of qooxdoo adoption.

having integrity and confidentiality as part of the transport is a
direct result of the routability property. SSL/TLS only works between
two points. if your message is supposed to be traveling through multiple
nodes, you need to encrypt the message itself -- tunneling it as
plaintext through an encrypted tunnel won't be enough. it's just like ip
vs ipsec.

i think you're somewhat right for authorization and audit
implementations, but authentication, along with integrity and
confidentiality of the communication between the client and the server
are common requirements. i think those requirements can only be
implemented using a well-defined sequences of cryptographic operations.
so why not define a standard, implement them in the core library and
save everybody else the hassle?

burak

I've thought of using that, it feels kinda messy but it looks like it's the only option so far so if I don't find a better solution I'll probably end up using that.. And then I'm gonna have to think of a way to have drag-and-drop-able "panels" so the components can be rearranged.

virtual Table / widget margin or cell padding

2009-11-24T23:53:29Z

Good morning,

I got another question regarding the virtual table.
How am I able to set a cell padding for each cell of my table (or a default
margin for each widget)? I'm using the virtual scroller with a
qx.ui.virtual.layer.WidgetCellSpan containing mostly label, textfield and
button widgets.

TIA, Daniel

You don't have to give me the code, you can just tell me what components I need to use.

The best way to explain the interface is that it looks like an IDE--a good way to explain it to fellow developers--with a single toolbar on top with drag-and-drop-able "panels" on the sides (there will be 3 columns)... It's really just like an IDE.

I tried using a Pane and it was going well, that is until I tried adding the 3rd column, that's when it blew in my face.

I really appreciate any help you can give me.

See http://demo.qooxdoo.org/devel/demobrowser/index.html#virtual~Pane_Column.html for a demo with the js code. It has 3 columns, maybe it's what you want :)

cheers,

Hoi Martin,

have you seen how it winks out of existance as you scrol the table
and comes back when you resize it vertically ? quite odd. I have
verified that my canvas painting code does not get activated the
whole time, so it must be something triggered by the scrolling
action of the table ... maybe some css tricks ? any ideas ?

The event you mentioned in your mail yesterday does not realy help
since it is fired BEFORE inerHTML gets changed ... I had to
subclass qx.ui.table.pane.Pane and do a

_scrollContent : function(rowOffset) {
this.base(arguments, rowOffset);
this.fireEvent("paneUpdated");
},

_updateAllRows : function() {
this.base(arguments);
this.fireEvent("paneUpdated");
}

with this I can then trigger the painting ... I guess it would be
nice to have this included in the normal pane.

cheers
tobi

Re: this reference

Hi Michael,

if you pass function pointers, you will loos the context (as you do in the
listener of the button). JavaScript offers a way of setting the context my
using the call method of functions:
guiMethod :function(method) {
method.call(this.server, this);
},
The first argument is the context and all following parameter will be
available as parameter in the called method.
Best,
Martin

Hi tobi,

I really like the canvas element on the table. :) I thought of a chart the
first time you mentioned your idea of the canvas in the table. Pretty nice!

Best,
Martin

IDE-like Interface

2009-11-24T21:08:33Z

Hello,

I'm really new to qooxdoo, as a matter of fact, this is my first project using qooxdoo.

The interface is quite simple and I'm sure creating is wouldn't take long, it's just that the API is still confusing me a bit, even with going through the API reference and the demos.

You don't have to give me the code, you can just tell me what components I need to use.

How to enable profiling

2009-11-24T20:59:01Z

Hi

From http://qooxdoo.org/documentation/0.8/profiling
>> How to enable the Profiler

>> Basically set the variant qx.aspects to on and be sure to include the class qx.dev.Profile. The class should be included before other classes.

So how exactly does one do this?.. I've been able to avoid the generator up until now.

I thought the profiler might help me find the clunky parts of my app. I've tried to dynamically build a user form that comprises of nested sub forms each with their own controller and model... generating that on a data reload can lock up the browser for 10 seconds... ouch! Maybe plain and simple is the way to go - hopefully the profiler can shed light as to where all the time is going.
