js : release an associative array : rely on GC ?

Jean-Baptiste BRIAUD -- Novlog — 2008-12-01T13:11:19

Hi, I'm using at several places what I called an associative array : this.array[key] = value; I would like to be sure I release memory used by the array. Would you advice me to rely on garbage collector or should I do something special ? Various solution : 1. this.array = null; // Is is enought ? 2. Browse the array and apply for each member array[i] = null; then do 1. 3. Something else ?

More on TileView contrib

Matthew Gregory — 2008-12-01T12:42:38

Hi All, A few people asked for some images/demos of my TileView widget. I've started the documentation on http://qooxdoo.org/contrib/project/tileview and there is also a demo online at http://qooxdoo.org/contrib/project/tileview that shows the TileView widget and how it can also be used with the standard List and ListItem. Enjoy!

theme sharing ?

Petr Kobalíček — 2008-12-01T00:24:03

Hi list, I have been started working on theme for our application. I thought that I will never do that, because application look is usually not important for me. Another reason was that I very liked theme in qooxdoo 0.7. After 0.8 release I started to use modern theme, it looks "modern", but rendering this theme is too much slow to us so we switched to Classic. My experiences with Classis theme is that it looks worse than Classic in 0.7, so modifications started :) Now, I have probably larger part done, I created some simple gradient background, switched colors to blue/orange style (probably very like office xp) and I'm quite happy with it. Reason for this post is that I want to know if it has some sense to sharing the theme, or all people are tuning own themes for their apps. Screenshot is provided as attachment. And small note about it: It's theme with lightweight 'web' design and performance is much better than 'Classic' one. Cheers - Petr -------------------------------------------------------------

scroller won't put up scroll bars

Kenny Tilton — 2008-11-30T04:08:09

I have a Label with rich=true holding a load of HTML in a smaller Scroll but I am not getting scroll bars. The _getContentHeightForWidth dutifully reports a height of 879 but strangely getHeight on the label returns null -- perhaps it has yet to be computed cuz I am printing all this just after assembling the scroller and label and inserting them in a tab page. Inspecting the element in firebug I see a height of 65 from the embedded DIV up through the Scroll, qx inserted contents included. The tab page in question has a Grow layout, and I could see in Firebug that as I resized the firbug pane the sizes change to reflect the sapce available above. (Cool!) [Note: I just got scrollbars to appear by specifying (not shown below) a minheight along with the allowGrowY. This was just a desperation hack to learn what I could learn. It would seem i need a better way than allowGrowY to fight off the Grow layout on the page, but Scroll is documented as having a layout that cannot be altered.] Code looks

Selenium

Jean-Baptiste BRIAUD -- Novlog — 2008-11-29T17:20:03

Hi, I read that Selenium is the test system used by qooxdoo team. Anyone was able to use it on Mac ? If yes, witch one : SeleniumIDE, Selenium core or Selenium RC ? I had very bad experience with any of them but I'd like to use it since this is the only one I know witch use real browser for testing.

IE 6 element.offsetParent

CSBrown — 2008-11-27T19:40:15

I'm using Qooxdoo 0.8 and have a situation in IE6 where line 190 of qx.dom.Hierarchy throws an 'Unspecified error' This appears to be happening when rendering a SelectBox for the first time although there are several containers around the select box that are also being rendered for the first time. Following a web search I found several references to IE6 and apparently 7 throwing an unspecified error when offsetParent is null. If I change the code in Hierarchy.js lines 190 - 192 to the following, the error is successfully hidden and the widgets are rendered correctly. try { if (!element.offsetParent) { return false; } } catch (e) { return false; } I've not seen the error occur in Firefox. Thanks, Chris

knowing which calls to listen for

metaperl — 2008-11-26T20:15:41

I am trying to make use of the tree widget: http://demo.qooxdoo.org/0.8.x/apiviewer/#qx.ui.tree However, I am aware that a working tree will need to have certain listeners added to it, such as 'changeSelection' and 'dblclick' My questions: - where would all the listeners for a tree be documented? - where is the API for .addListener() documented? I'm guessing it's way up in the object hierarchy.

some general queries in 0.8

Gaurav Jauhri — 2008-11-26T16:59:01

hi, I have a class A extending the splitpane("horizontal") this.add(abc,0); abc another clas extending VBOX this.add(xyz,1); now xyz is another class which extends splitpane("vertical"); since i have already given the flex value 1, so it should occupy all the right part of the class A. But it is not showing the expected, is there is any way to set the width of the right side of the splitpane to 100%.

Fix table height in visible row

Jean-Baptiste BRIAUD -- Novlog — 2008-11-26T14:53:13

Hi, I'd like to fix a table height so a given number of row is always visible. For example, the table will have 10 visible rows, whatever the number of row is in real. So, if less than 10 row are in the model, there will be blank space after the last row, else, a scrollbar will be there or even better, the scroll bar will always be there. Is there a way to do that ? Thanks !

alignX property of VBox - not working

Amit Rana — 2008-11-26T14:15:55

Hi, I am using Qooxdoo v0.8 SDK. When I try to set the alignX property for my conatiner (layout VBox), it gives me an error : Assertion error! The property 'alignX' is not supported by the box layout!: Called assert with 'false' I checked in API, and alignX is indeed a property of VBox. I also checked in the SDK library class of VBox and got the code as : this.assert(name === "flex" || name === "height", "The property '"+name+"' is not supported by the box layout!"); My code snipet is : this._myBar = new abc.myBarClass(); //extend : qx.ui.container.Composite and has qx.ui.layout.HBox layout this.add(this._filterBar, {alignX: "right"}); // extend : qx.ui.container.Composite and has qx.ui.layout.VBox layout Basically, I am trying to add a container (this._myBar) into another container (with VBox layout). Can someone point me the error here ? Regards

cannot get HBox to render

Hello, I got the 'Hello World' example working. Then I tried to replace var doc = this.getRoot(); with the code in the Image demo http://demo.qooxdoo.org/current/demobrowser/#widget~Image.html that creates an HBox: var layout = new qx.ui.layout.HBox(); layout.setSpacing(20); var doc = new qx.ui.container.Composite(layout); this.getRoot().add(doc, {left:20,top:20}); but nothing is rendered and no errors are thrown in the Console.

Icon (images) and memory footprint

Jean-Baptiste BRIAUD -- Novlog — 2008-11-25T18:15:53

Hi, I'm trying to manage memory footprint for all that icons on screen where 80% could be the same shared instance of Image. I just realize I can't set the image instance on tabview.Page, on Image itself ... the API appears to always be the URL string. I think that with the possibility to set the image instance directly I'll be fine, is there a way to do that ? Otherwise, how then can I (simply) ensure my icons are singleton ?

Can a widget listen for a property change event?

Patrick Paskvan — 2008-11-25T19:05:55

Hello List, I have a simple question that I'm quite sure was answered on the list in the past, but I am unable to find the answer in the archives. The question is: can a qooxdoo widget listen for a custom property data change event? In our case, a property is expected to be an array and it names a change event "changeData". Elsewhere in the same class a SelectBox is created and to it a listener for the "changeData" event is added. The handler for the event would be a generic handler that would use e.getTarget() to get a reference to the widget for which the handler was called and e.getData() would return the new data contained in the property. The handler could then go on to populate the select box. Something is wrong with my premise or implementation, though. A warning is thrown when the event listener is added to the select box: "There is no event handler for the event 'changeData' on target 'qx.ui.form.SelectBox[blah]" We're using 0.8. At the risk of being too verbose, here is an untested code

Demo browser bom/Clip is broken using IE7

Helder Magalhães — 2008-11-25T17:53:31

While browsing through the Demo browser, I stumbled across a minor potential issue: resetting the clip [1] failed using Internet Explorer 7. Worked fine using Firefox 3. I tried checking using current trunk version but the build failed for some obscure reason (sounds like development has temporarily broke the trunk). Sorry if this is a duplicate report or a false alarm (already fixed in trunk) but I'd prefer sending it instead of getting lost within my TODO list... ;-) Hope this helps, Helder Magalhães [1] http://demo.qooxdoo.org/current/demobrowser/#bom~Clip.html

Flash Objects in a Window Qx 0.8

MootCycle — 2008-11-24T20:50:00

I just wanted to make a quick post on how to get Flash objects into a qx.ui.window.Window. No one has asked this question, but it wasn't immediately obvious to me and I wanted to make a post here in case someone else has the same issue in the future. Here's some code: var doc = this.getRoot(); var window = new qx.ui.window.Window("Window"); window.setLayout(new qx.ui.layout.Canvas()); doc.add(window, {top: 400, left: 400}); var layout = new qx.ui.layout.Basic(); var container = new qx.ui.container.Composite(layout); container.setHeight(500); container.setWidth(600); window.add(container, {top: 5, left: 80}); window.addListener("appear", function() { var domElement = container.getContentElement().getDomElement(); var flash = qx.bom.Flash.create(domElement, "Flash.swf", "flashMovie"); }); window.show(); With qx.bom.Flash.create() the DOM element has to exist (the window has to be shown) before the method can be called. -Dan

Application Integration

Markus Wolf — 2008-11-24T17:21:16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, I'm new to qooxdoo and want to integrate it into our existing application. The docs are good so far and I managed to create a simple example with integration as stated on the website docs. But.... We have existing html files which are served by a java application server and a uri naming scheme like this: The main file: http://somehost/survey//index.html All resource files: http://somehost/survey/resource//path/to/resource.js The problem with the qooxdoo integration is that the uris for the .js files are based on the url of the current document. Therefore we could not integrate it in our application. Is there a way around this? It would be good to give the user/developer an option to decide to load the required files (at least for a release build) with script statements (should only require .js and -0.js I guess). Can anyone give me a hint on this problem? Thanks Markus Wolf - -- NMMN - New Media Markets & Networks GmbH G
