Re: More on TileView contrib

Andreas Ecker — 2008-12-01T21:51:04

Hi Matt, congrats, your TileView is really nice. :-) I'd suggest to file "real" bug reports into qooxdoo's Bugzilla. You can easily reference other bugs in there, that either belong to the framework or other contribs you might depend on. Projects in qooxdoo-contrib are "first-class citizens" that are supposed to take advantage of the existing infrastructure (SVN, wiki, etc.). See the wiki code at http://qooxdoo.org/contrib/project#tileview for some handy interwiki links, that you could also add to your TileView homepage if you like: [[ContribReportBug>TileView|Report Bug]] lets you easily enter bugs for your contribution, and is expanded to http://bugzilla.qooxdoo.org/enter_bug.cgi?product=contrib&component=TileView [[ContribShowBugs>TileView|Show Bugs]] searches for any open bugs If you like to read more about interwiki support, see http://qooxdoo.org/documentation/general/wiki_interwiki Hope you like the infrastructure we provide for contributions? We'd like to improve it further, so any feedback and collaboration is appreciated.

Themes - Color variants

Petr Kobalíček — 2008-12-01T20:12:42

Hi list, how is correct way to create color variants for some theme. For example I'm playing with new theme and I want to create two or three color variants. There are several parts (called meta themes in qooxdoo?) of theme that must be overriden: - Colors - this is simplest and shortest, just fill different values - Decorations - I think that in this part I will duplicate everything - Appearance - I think that this is not needed to override, it uses Colors and Decorators Because I'm lazy in duplicating stuff, my idea is this: (function(){ // list of theme descriptions var description = [ // individual items { name: "Blue", colors: { ... } // colors resource: "path_for_resources" } ]; description.forEach(item, function(){ qx.Theme.define("bfly.theme.light." + item.name, { colors: item.colors }); qx.Theme.define("bfly.theme.light." + item.name, { resource : item.resource, ... }); }); }()); ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

Re: New Properties' Validation and Data binding

Petr Kobalíček — 2008-12-01T19:35:52

Hi Guilherme, this is good starting point. I have some small experiences with data validation and I must agree with you. I think that object should be able to be in non-valid state, so validation should be explicit, not implicit. My second idea is, that validation is usually done in control itself or more complex validation is done by server, so implementing validation in properties is, I think, bad step. Example can be situation that something is wrong in the server and you want to fix it. If validation is in properties and server replies you bad value, you can't instantiate the model object. I'm implementing validation by this way: - I have object that I need to validate - I will create validation schema (this can be json schema, or some kind of schema with instantiated objects describing each fields) - Currently my schema uses also widgets, so for example I have TextField, FloatField, ImageField, etc classes that I can instantiate and add all together to some form (not ui object). And finally I can call, form.validate() or validate() on individual items So, validation in models/objects itself will be always limiting factor in some situations that will always happen and extending this can be nightmare for people that wants more control or different approach. Why not to model validation like this ?: Instantiated object or dict {} that holds the data (valid or invalid, don't care) | Validator based on validation schemas | Input/Output And finally user interface can be like this: Instantiated object or dict {} that holds the data (valid or invalid, don't care) | User Interface (usually some kind of form), fields based on validations schemas, field layout based on different ones (grouping, or hand written - more control) Cheers and sorry for my limited English here - Petr 2008/12/1 Guilherme Aiolfi gmail.com>: ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

Hi Matthew, thank you for your work:) Is any chance to use new implementation of heightForWidth before friday ?

Height for Width in layouts working

Andreas Junghans — 2008-12-01T14:21:09

Hi there, Am 01.12.2008 um 14:50 schrieb Matthew Gregory: Sorry, but I don't think this is true. "delete this.array" simply removes the "array" key from the associative array that is referenced by "this". It doesn't really "delete" it (as there may be other references to the object), and it's certainly not slower than assigning it to null. (I suppose you didn't really test the performance of "delete". If you did, I'd be interested in the results.) More comments below. In general, the browser GC cleans up any unreferenced object. Unfortunately, there's one big exception: The GC of Microsoft's Internet Explorer cannot cope with cyclic references between "pure" JavaScript objects and DOM objects. Take a look at this code snippet: var domObject = document.createElement("div"); var jsObject = new Object(); domObject.pointerToJS = jsObject; jsObject.pointerToDOM = domObject; Here you have a cyclic dependency between the div element and jsObject. There are also much more subtle ways that can lead to such a dependency (including closures). The big problem is that IE doesn't free the memory of such cycles - ever! Not even when you leave the current page. (At least this is true for IE up to version 7 - don't know about 8.) This is enough if you don't store any DOM references (directly or indirectly) in the array. The "array" key itself is still held in memory (a simple string). If you want to get rid of it, use "delete this.array", but that's not necessary if you reuse the same key later on. Not necessary (except to clean up DOM references). As long as no DOM references are involved, you don't even need to set this.array to null. If the object referenced by "this" falls out of scope and isn't referenced from anywhere anymore, it's cleaned up automatically (including the array property).

You could use "delete this.array" to free the memory instantly, it is much slower than assigning it to null and waiting for the GC though.

Re: scroller won't put up scroll bars

Kenny Tilton — 2008-12-01T13:43:36

Thx, Alexander. I was using a Scroll widget but there were no scroll bars displayed because it thought the contents were not too big to fit in the scroll pane. The Firebug inspector confirmed the Scroll's understanding. The problem was that an ascendant Grow layout was dynamically modifying the height of the too-large widget (an embed.HTML in fact). Examination of the relevant code suggests only min/maxHeight are respected under a Grow layout, and that is how I worked around the problem. cheers, ken

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 ?
