Re: single/atomic setter for group properties?

Petr Kobalíček — 2008-12-03T21:34:34

Hi Martin, I don't know if property system is good for drawing pixels. Isn't there a simplest way ? For example you can create method drawPixel(x, y) that will do what you need. Maybe I not understand your question and core developers will help you much more:) Cheers - Petr 2008/12/3 Lars Martin itemis.de>: ------------------------------------------------------------------------- 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=/

single/atomic setter for group properties?

Lars Martin — 2008-12-03T21:26:58

Hi, I newly subscribed the list because I'm currently developing a RAP custom widget and I do have some problems with the JavaScript counterpart of my Java implementation. This question is regarding qooxdoos property system. I'm sure I missed some important points. My RAP widget passes an int[] named "pixel" to qooxdoo and the property system automatically call "setX" and "setY" to set the members from incoming int[] as below: properties : { x : { apply : "_drawPixel", init : null }, y : { apply : "_drawPixel", init : null }, pixel : { check : "Array", group : [ "x", "y" ] } }, members : { _drawPixel : function(value, old) { // draw a pixel at [x,y] }, ... } My question is: how can I ensure a single or atomic setter for grouped properties? If I want to draw a point at [x,y] how can I ensure that the _drawPixel method is called only once. Better said: is called only when property x AND y is initialized? Is there something like? pixel : { check : "Array", group :

request.setFormField question

Jean-Baptiste BRIAUD -- Novlog — 2008-12-03T20:53:51

Hi, I'm using io.request.setFormField to pass couple of key/value to the backend. It work fine for simple value like name of a person. Now, I have to pass the equivalent of an HTML multiple select, how do I use (encode ?) that using the request ? Should I use setFormField method ? If yes, what is the convention for the key (vId) or the value (vValue) ?

Re: Creating a printable page

Hi Stefan, I thought of doing something like that but that would require duplicating some logic on the backend (in C++) which is already on the browser side (in javascript) to generate the report. I am most likely going to be going that route in the future but I was hoping to avoid doing this initially as it would require more time than I really have to work on this app. Thanks Eric On 12/3/2008 11:24 AM, Stefan Volbers wrote: results. in afraid ------------------------------------------------------------------------- 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=/

[PATCH] Minor documentation issues in Remote table model

Helder Magalhães — 2008-12-03T17:17:45

Few minor documentation fixes for legacy branch: * Introduction paragraph slightly rewritten * Idea was to make the somehow confuse text a bit more but of course this is arguable * Typo: "asynchroniously" --> "asynchronously" (fixed during paragraph rework) * Typo: "resently" --> "recently" * Apparently deceiving information: "clearCacheOnRemove" property * "If false the rows are removed"... --> "If true the rows are removed"... * I've looked into the code before changing this but please confirm if I missed something * Typo: "removeRow" method * "Removes a rows from the model." --> "Removes a row from the model." http://www.nabble.com/file/p20817355/Remote-FewDocumentationIssues.patch Remote-FewDocumentationIssues.patch Although this was created from the legacy (0.7.x) branch, just checked that the trunk also shares this code, although I haven't attempted to apply the patch there (it may not apply cleanly to the trunk, specially because folder structure is different). Hope this helps,

Re: Creating a printable page

Stefan Volbers — 2008-12-03T16:24:47

Hi Eric, not quite the same thing but somewhat comparable: having to produce a printable report out of my qooxdoo app, I have an event listener on a clickable button which opens an external native browser window with the location of a (PHP-) script like var reportbutton = new qx.ui.form.Button("Create report"); reportbutton.addListener("execute", function() { var url = "http://" + location.host + reportpath + "report.php?target=" + target; window.open(url, "_blank"); }, this); This in turn (mis-)uses my RPC classes to retrieve the database information needed in the report and thus creates a PDF from the results. So I'm creating the external page not with qooxdoo, but with PHP, and the result is not HTML, but PDF. Nonetheless I get printable results in an external page. I am sure anything similar could be achieved with any server scripting language like Perl or Java or Ruby or whatever. If you definitely need to create the page with qooxdoo means, I'm afraid I can't help you there - I a

Re: No fancy table structure in qooxdoo?

Kenny Tilton — 2008-12-03T11:21:03

Thx, Jean-Baptiste. Hmmm. I forgot to mention that this table has a Remote data model behind it, so I need the table to automatically map from JSON data to table cells where I can specify variable numbers of rows/columns. Or punt and have the data model serve HTML as data to a one-column table with an HTML Cell renderer. But you have given me an hybrid idea: JSON data, custom cell renderer to build a grid... ah, maybe not: looks like the only candidate is Abstract and that wants me to generate HTML and qx.HTML does not do tables. Send in the long snapper. :) cheers, kenny ------------------------------------------------------------------------- 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: Events - stopPropogation() not working as it should

Fabian Jakobs — 2008-12-03T10:59:09

Hi Amit, First of all "stopPropagation" is only supposed to be used in events, which bubble up the widget hierarchy, like mouse and key events. Many events like property change or selection events don't bubble. "changeSelected" is one of those non bubbling events. Even if it was bubbling, "stopPropagation()" would not do what you describe. Even if you call it, it will run all event listeners on the current event target. Only event target up the widget hierarchy will be skipped. This is how "stopPropagation()" works natively in the browser as well. Quote from the W3C event spec: "Any event handler may choose to prevent further event propagation by calling the stopPropagation method of the Event interface. If any EventListener calls this method, all additional EventListeners on the current EventTarget will be triggered but bubbling will cease at that level. Only one call to stopPropagation is required to prevent further

Events - stopPropogation() not working as it should

Amit Rana — 2008-12-03T09:43:13

Hi, I am using the "changeSelected" event on qx.ui.tabview.TabView. Now, when I write e.stopPropagation(); in my event listener function, Firebug gives an error stating : Assertion error! Cannot stop propagation on a non bubbling event: changeSelected: Called assertTrue with 'false' I made my event as a bubbling event as e.setBubbles(true); and then called e.stopPropagation();. Now, I don't get any error but my event lister gets called twice. My tabview initially has 2 tabs - Actual and dummy. The eventlistener is set on Tabview and the Actual tab is selected by default. When the dummy tab is clicked, my eventlistener checks which tab is clicked (based on page label). If dummy is clicked, it deletes the dummy tab, adds a new tab and then inserts dummy to its end (functionality similar to that in IE7). If I write e.stopPropagation(), I get the desired functionality but with errors in Firebug. If I don't write e.stopPropagation() or I write e.setBubbles(true); e.stopPropagation();, then on click

Re: Retrieving Properties "check" value

Alexander Back — 2008-12-03T08:51:43

Hi Guilherme, my first answer fast obviously too fast. There is a possibility to get the value of the "check" key. This --snip-- qx.ui.basic.Label.$$properties.content.check --snip-- will the value of the "check" key of the "content" property of the label class. One thing is important: the "$$properties" is attached at the class not at the instance of a label. If you want to get the value having an instance you need to use --snip-- myLabelInstance.constructor.$$properties.content.check --snip-- since the class is accessible through the "constructor" key of the instance. cheers, Alex Alexander Back wrote: ------------------------------------------------------------------------- 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=/

Alexander Back — 2008-12-03T08:31:49

Hi Guilherme, Guilherme Aiolfi wrote: The "check" value of a property gets transformed into a check within the setter of the property. So there is no possibility to get the type the property accepts - as least I do not know about one. For example the setter of the "content" property at "qx.ui.basic.Label" will incorporate the following --snip-- var msg = "Invalid incoming value for property 'content' of class 'qx.ui.basic.Label'"; if (value !== null) { if (!(qx.core.Assert.assertString(value, msg) || true)) { prop.error(this, 5, "content", "set", value); } } --snip-- if the check will have the value "String".

No fancy table structure in qooxdoo?

Kenny Tilton — 2008-12-03T04:46:03

Straight HTML tables (and other JS frameworks) allow one to have a little fun and get away from straight columns/rows. For example, a single data cell can take up two columns and three rows, while the other fields on those three rows all just use a row each (but may vary in how many columns are used (columns just being a specified width). Picture a photoID alongside a grid of personal information. It seems I can do that with a one-column table and an HTML cell renderer, but I thought I would check to make sure I was not missing something in qooxdoo. cheers, kenny

Re: New Properties' Validation and Data binding

Petr Kobalíček — 2008-12-02T17:54:45

Hi Martin, yes, you are right that I talkem mainly about form validation:) Explanation: Form validation is very similar to model validation for me. In form its probably everything that is changeable in model, so if you want to validate something, you will do it in the form (or some external validator) and you set validated data to the model. What I'm talking about server side validation is fact, that in some cases, valid model in the client can be non-valid on the server. Let me explain it: - In ajax applications you are usually working with some data. Model is usually table and instance of model is usually row, connections between data is usually created using selectbox, listbox and similar widgets. Imagine that you have selected valid category for the product and that category was deleted by somebody else. When saving data to the server, it should be able to tell you where is the problem and in client you should be able to load new category data. - This was example from my life, it's rare, but it's pos
