Re: Problem with forms and radio buttons

2009-11-11T01:24:42Z

Hello Derrell,

All model properties don't have the fallback to its value. What is clear is,
that we need to supply a possibility to specify a different model than its
value. But I don't know if we need a fallback to the value / label. All
other widgets not having the model property use the value so you don't run
into that problem.

The only widgets with the model property which could have that fallback are:

qx.ui.form.RadioButton
qx.ui.menu.RadioButton
qx.ui.form.CheckBox
qx.ui.toolbar.RadioButton

qx.ui.form.ListItem
qx.ui.tree.AbstractTreeItem

The first group could have its value as fallback. So you get 'true' or
'false' as model if no model is specified. But how do we know that no model
is specified? Perhaps someone would like to have null as model? Imagine a
set of radio boxes with the first one showing "no thanks" or anything like
that.
The same is true for the second group where it becomes the label instead of
the value.
What do you think? I'm not sure which situation is worse. Either you can not
specify null as model or you have no fallback!

Regards,
Martin

table tutorial for beginners

2009-11-11T00:40:31Z

I'm using qx for a while, but since now I didn't need to use the table widget.
I red the API for table: http://demo.qooxdoo.org/0.8.x/apiviewer/#qx.ui.table, but I didn't really understand, how to work with this widget.
Unfortunately the link in API to the qx wiki is broken, so now I don't have a clue where to begin.
Do you know about a table widget tutorial for beginners somewhere.

My goal is shortly the following.
I would like to make three tables with different datas.
They could be simple tables (not remote).
They have to have three columns: first with checkboxes, second with name, third with ID.
The checkboxes aren't always visible, only in certain circumstances.
I have cache the click on a checkbox separatelly from a click on a name or id.
When checkboxes are visible I would like to make possibility to filter the table rows: all, checked, unchecked.

Any help would be appreciated.
Thanks.

Qooxdoo eclipse namespace

2009-11-11T00:06:10Z

Hello,

I have a problem with qooxdoo or eclipse.
I want to use eclipse as IDE for qooxdoo development.
I use QXDT and added the qooxdoo library to my eclipse project.
but if I type qx.ui. and press ctrl+space I get the message "no default/template proposals" - "no completions available".

Could you tell me please how I can use the autocompletion?

Thanks

Re: Data binding questions

2009-11-10T23:56:36Z

Hello Jean-Noël,

sorry for the late answer. Part of the qooxdoo team including me has been on
the JSConf in Berlin over the weekend so we had our weekend on monday and
thursday. Thats why i havent answered jet.

The controller does not have any method for modifying bindings because the
idea of using a controller is not to know anything about the bindings. So I
tried to keep the whole single value binding stuff out of the sight of the
controller user.
I think the code you are looking for would look something like this:

controller.setModel(null);
controller.setTarget(null);

That should remove all bindings from the model and the target including all
listener.

Best,
Martin

If you just want to remove all fonts, why take care of the binding. This
should be the problem of the controller. ;) So just use the last line and
the list will be empty.

2) You can achieve that by using two bindings. Lets say object A has the
data array stored in property a. Now you can set up a single value binding
like this:
A.bind("a", listController, "model");
The list controller takes care of the given model and the single value
binding takes care of setting the model. Thats the most elegant way to do it
i think.

What did I do wrong to cause this error?

Hi,

I'm trying to use the properties defined in Qooxdoo (0.8.3), but the following code:
properties: {

mode: {

init: "mode1",

check: ["mode1", "mode2"],

event: "changeMode"

},

...

does not raise any error when I try to assign the string "test" to the property (or any other).

I tried with an integer property, trying to assign a string to it, and I still had no error.

Did I miss something?

Re: Odd error after clearing child widgets in a composite

Did you see my other email?
Try using .destroy() instead of .dispose(). This way the widgets will be
completely removed from the array you are refering to.

That is correct. setWidth() is setting the *preferred* width. You can require that the width be exactly what you want with setMinWidth() and setMaxWidth().

Thanks, that worked. What bugs me is that the same ratio given to the field's flex property and table's column resizing gives rise to different widths and that too not a subtle difference. I guess it's ok, since we can always align them using this technique :)

This seems like a qooxdoo error to me. Is it? Or am I doing something wrong?

Hi skar,

maybe I'm missing something here, but wouldn't it be best to dynamically 
set the text field width to the actual table column width? This worked 
for me, after removing the flex setting for field_encapsulator:

        tcm.addListener("widthChanged", function(e) {
          var col = e.getData().col;
          var newWidth = e.getData().newWidth;
          this.field_container.getChildren()[col].setWidth(newWidth);
        }, this);

Thanks for the snippet. However, the fields and the columns don't align now too. It seems setting the width is only a guidance and the field container's children grow further. For eg, in my laptop, the width is 1280.

APP.table.getBounds() Object left=0 top=43 width=1240 height=439
APP.field_container.getBounds() Object left=0 top=10 width=1240 height=23
tcm.getColumnWidth(0) 586
APP.field_container.getChildren()[0].getBounds() Object left=0 top=0 width=597 height=23
APP.field_container.getChildren()[0].getWidth() 586

As seen above, the first field's width is set equal to 586, the same as the table's first column, however, it occupies 597 px.

Any idea why the flex property for the fields don't give the same width as the table's resize behavior, though both have the same ratio?

cheers,
skar.

That may be a little too late since it's undone, but here are our results for a
~400 classes application when using the file TreeLoader.py of r20582 and
sticking with the 0.8.3 release for the other files.

./generate.py build (no cache) - 0.8.3 release:

real 1m47.422s
user 1m44.002s
sys 0m1.792s

Memory usage: ~50 MB

./generate.py build (no cache) - r20582:

real 2m19.662s
user 2m17.909s
sys 0m1.612s

Memory usage: ~550 MB

====================================================

./generate.py source (no cache) - 0.8.3 release:

real 0m38.235s
user 0m37.466s
sys 0m0.680s

Memory usage: ~46 MB

./generate.py source (no cache) - r20582:

real 0m40.432s
user 0m39.554s
sys 0m0.720s

Memory usage: up to 280 MB

The new version was always slower and used more memory.

Thanks for trying to improve the build speed :)

Re: Odd error after clearing child widgets in a composite

2009-11-10T03:20:10Z

Try using .destroy() instead of .dispose().

IIRC destroy() will basically remove the widget from it's parent and the
dispose it. Without removing it from the parent first you leave a
reference to it behind which is what I think is causing your error.

Re: doubt about layout

2009-11-10T03:16:28Z

Hi skar,

maybe I'm missing something here, but wouldn't it be best to dynamically
set the text field width to the actual table column width? This worked
for me, after removing the flex setting for field_encapsulator:

tcm.addListener("widthChanged", function(e) {
var col = e.getData().col;
var newWidth = e.getData().newWidth;
this.field_container.getChildren()[col].setWidth(newWidth);
}, this);

Regards,
Daniel

Odd error after clearing child widgets in a composite

2009-11-10T03:08:48Z

Hi.

I have this container:

var layout = new qx.ui.layout.Grid(4, 4);
layout.setColumnFlex(1, 1);
layout.setColumnFlex(4, 1);
layout.setColumnMinWidth(3, 20);
this.__fieldsContainer = new qx.ui.container.Composite(layout);

At some point, I add widgets to it. Later on, I try to remove them, in order to add fresh controls to it, like this:

var children = container.getChildren();
while(children.length > 0)
children[children.length - 1].dispose();

The removal works without problems. However, later on, when executing the same code I executed earlier on to fill the container, I get an odd error with a stack trace comming from deep within qooxdoo itself:

Line 10748 of linked script http://localhost/folder/script/myapp.js
if(C==null||r==null){throw new Error("The layout properties 'row' and 'column' must be defined!");
Line 11046 of linked script http://localhost/folder/script/myapp.js

function(){if(!self.__callback){return a.apply(this,arguments);
... Line 1495 of linked script http://localhost/folder/script/myapp.js
function(event){return a.call(self||this,event||window.event);

The code which adds the new controls is executed in the same thread as the code clearing the container, and finishes OK. The error happens later on, when the rendering happens, it seems, so I cannot trace the error back into my code. Unfortunately, this time I also don't have time to run the source build with test data to see what happens.

Any ideas?

Re: use codepress into qooxdoo

2009-11-10T03:05:24Z

Hello ,

Thank for your help

I think I have solved the problem so:

var doc = this.getRoot();
iframeName = "pippo";
var html ="prova.html";

this.iframe = new qx.ui.embed.Iframe()
this.iframe.setSource(html);

doc.add(this.iframe, {
left: 100,
top: 50,
right : 20,
bottom : 20
});

I included prova.html into directory ....\source\ prova.html of my
application

Regards
Antonino

You are usually better off just storing a reference to each widget than
trying to progmatically find it in a child array or similar.

Hello Cristian,

Thanks for your help

I think I have solved the problem.

Re: Generator Memory Usage

2009-11-10T02:38:32Z

You're right, there's something inherently weird about this patch. My own measurements do not match with my initial figures (using a different platform, though). I undid it in trunk (r20591). BTW, your figures look strange too (e.g. build times are *bigger* with cache than without - if this were true the whole cache would be worthless).

Thanks to all for testing anyway.

No, updating tool/ to trunk alone wouldn't work, as there are depenpendencies into the framework (concerning part loading). But it's even simpler: You can simply update the file tool/pylib/generator/code/TreeLoader.py to its trunk version. This change is compatible with the 0.8.3 release.

Let us know how it works.
For a skeleton app:

My "./generate.py source" has reduced from taking 5-6 secs to 3.03 secs or thereabouts. But my build time has gone from the same 5-6 secs to around 11-12 secs. I'm on trunk 20583. Both the times are with the cache available. With no cache, the times are almost the same for both source and build at around 100-120 secs.

Also I couldn't see any memory usage around 500 MB. Without cache, source and build took around 100 MB RSZ and VSZ was only a little higher. With cache, source was around 16-20 MB and build took around 36-40 MB. So memory usage isn't a problem for me, nor should it be for anyone else.

For my app:

Memory usage is the same for both my project as well as a skeleton app. Time for source and build also the same around 100-120 secs without cache. With cache, times are bigger at around 5 secs for source and 13 secs for build. So bigger project takes longer times, but memory consumption stays the same.

If you can quicken the build time also, it'd be awesome :)

cheers,
skar.

doubt about layout

2009-11-10T01:39:20Z

Hi,

I've got a table with n columns and also a corresponding no.of text
fields above the table. I want the input fields to align horizontally
with the table's columns. Also, I want the alignment to stay even if the
browser is resized or if the container size is set to a fixed size
instead of occupying all the browser space.

When I assign a flex value of 48% to each of the fields and also to the
columns, the size taken by the two aren't equal. And the save button
takes more than 4% of the horizontal space.

The sample code is as follows:

calling components

2009-11-09T12:07:10Z

I'm sure this has been answered many times before, but I haven't had luck finding a related post.

Q: What is/are the best ways for identifying and calling qooxdoo components anywhere from within a qooxdoo application? For example, if I'm inside a an event handling function and I want to call a button or adjust a contentpane? I was originally looking for something like getRoot().getChildren().

Thanks!

Re: pass a functions name to a class

good idea. i'll make it this way. thanks.

Re: pass a functions name to a class

2009-11-09T05:20:57Z

As a small optimization you could replace this:

construct: function(currFn) {
this.addListener("click", function(e) {
currFn(e);
});
});

with this:

construct: function(currFn) {
this.addListener("click", currFn);
});

thx
I'm going to try it immediately

Re: pass a functions name to a class

2009-11-09T04:50:30Z

Hi Sikd,

yes, you can pass the reference from the function. Your example is
nearly correct, only the bracket are sometimes wrong:

<code>
var currentFunction = qx.myFunctions.myFunction1; // <- no bracket necessary
var myButton1 = new qx.myButton(currentFunction);

var currentFunction = qx.myFunctions.myFunction2; // <- no bracket necessary
var myButton2 = new qx.myButton(currentFunction);
</code>

In the constructor you can call the function like:

<code>
construct: function(currFn) {
