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 : [ "x", "y" ], apply : "_drawPixel" } Any help is appreciated.

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) ? Thanks ! ------------------------------------------------------------------------- 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, Helder Magalhães

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 clicking dummy tab, 2 tabs get added instead of 1 (ie. eventListener gets called twice), which I don't want. Here is a snippet of my code : this._tabView.addListener("changeSelected",this._choosePage,this); //in class constructor _choosePage: function(e){ //member function var tabView = e.getTarget(); var pg = tabView.getSelected(); alert(pg.getLabel()); if(pg.getLabel()== ""){ //if dummy tab is clicked this._dummytab(); //deleting dummy tab and add a new tab e.setBubbles(true); //Writing this line prevents the Firebug error but calls the eventListener twice and causes 2 tabs to get added instead of 1 e.stopPropagation(); // Writing just this without above line adds just 1 tab (desired) but causes Firebug error this._tabView.addListener("changeSelected",this._choosePage,this); //since listener was removed } } _dummytab: function(){ this._tabView.removeListener("changeSelected",this._choosePage,this); //else tabView.remove() calls the eventListener _choosePage() again this._tabView.remove(targetPage); this._addtab(); //adds a new tab and then dummy tab } ------------------------------------------------------------------------- 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=/

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

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=/

Height for Width in layouts working

Fabian Jakobs — 2008-12-01T16:43:20

Hi, I just want to let you know the I just implemented "height for width" in layouts. This is the last missing piece to get the FlowLayout fully functional. Chris, I have updated your FlowLayout contrib to make use of this feature. Its still basic but I'm sure you can easily add the missing features now. Best Fabian

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.

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.

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 like this: processConceptResults: function (e) { var ctab = this.conceptTab; ctab.setEnabled(true); var lbl = new qx.ui.basic.Label().set({ rich: true, allowGrowY: false, content: e.getContent() }); var scroller = new qx.ui.container.Scroll().set({height:200}); scroller.add(lbl); ctab.add(scroller); this.tabView.setSelected(ctab); lbl.debug("lbl content height"+lbl._getContentHeightForWidth()); lbl.debug("lbl height "+lbl.getHeight()); scroller.debug("scroller height "+scroller.getHeight()); }, I will try setting the minHeight programmatically to the height for width, but that seems wrong. Is there a better way? cheers, ken

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

Managing resources using resourceUri

Amit Rana — 2008-11-27T10:54:40

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 !
