Question of selection with editable Spark DataGrid

• Play with the spark datagrid

  I play with the spark datagrid and I have a column implemented as follows:

  "< GridColumn width ="140"headerText ="Margin"headerText.editMode =" Margin (montage) "dataField ="margin"editable ="false"editable.editMode =" true "itemRenderer ="gridColumnRenderer">
  < / GridColumn >

  I would like that the rendering of the element to change color depending on the State of the outerDocuent, is it possible?

  I tried this but can't seem to the outerdocument

  <? XML version = "1.0" encoding = "utf-8"? >
  " < = xmlns:fx s:ItemRenderer ' http://ns.Adobe.com/MXML/2009 "
  xmlns:s = "library://ns.adobe.com/flex/spark".
  xmlns:MX = "library://ns.adobe.com/flex/mx".
  autoDrawBackground = "true" >
  
  < s:Label text = "{data .margin}" backgroundColor = "{outerDocument.currentState == 'editMode'? 0xffffff:0xdddddd}" / > "
  
  < / s:ItemRenderer >

  I believe that you should not use GridItemRenderer instead of ItemRenderer as base class for renderers in spark DataGrid.  It works if you change that?

• Change the color of the selected TEXT to line Spark DataGrid

  Hello

  Does anyone know of a way to change the color of the text of the selected line in a spark DataGrid? I am able to change the color of flipping, etc, but can't seem to find a way to change the color of the text.

  Let's say the default value is black for all lines. I want to make the color of the text of the line selected, for example, red. Ideas through CSS or Skinning?

  Thank you

  Victor

  I think you need to create a custom item Renderer.

  If you use FlashBuilder, just ask to a default one for you and look at the code.

  I wil put a code here, but everything will be guess I can't check my answer just now. So what I write may be incorrect. I'll look again to change you

  NOTE PLEASE. WHAT CAN BE WRONG. I JUST TRIED TO REMEMBER OFF THE TOP OF MY HEAD!

  http://ns.Adobe.com/MXML/2009.

  Search for the 'format' function

  {

  lblData.text = column.labelFunction (data, column);

• Questions about Spark DataGrid (header font Styles, gradient header)

  Just starting in 4.5 SDK and just a little confused on the Spark DataGrid.

  (1) to set the font style for only the head, but do not see these properties in the designer... as they seem to apply to each part of the data grid.

  (2) want to set a linear gradient in the header using two specific colors, alphas, and ratios.  Don't know where to put it now.

  I think that's all for now.  What I did with it up to now, I love... but obviously not as many as MX DataGrid user documentation.

  Thanks in advance!

  You can do a column header converters by setting the property of the column. But if you want to exchange all the headers, the header is rendered must be specified in the skin. A trick you can do is subclass the Datagridskin and replace the declaration of 'his '. It also works with other parts of the skin.

• Spark DataGrid edit

  Hello

  I find them to be allocated and cannot find a way to make the Spark DataGrid editable for the user input.

  Is it possible at all, or do I have to use MX DataGrid?

  Maybe you can try a preliminary validation before the award of 'data '.

  Of

  valueDisplay.selected = data[column.dataField] as Boolean;
  

  TO:

  if(data)
  {
      valueDisplay.selected = data[column.dataField] as Boolean;
  }
  

  I would like to know if it works.

• Can we synchronize permission selected with the settings of operating system Notifications BB10 for our Application.

  Steps to follow:
  BB10 device--> settings--> Notifications--> Applications--> [name of your application]--> all alerts [Toggle button]

  I have an obligation to check whether or not 'All alerts' is allowed through settings when the application is running. To check if we can synchronize permission selected with the settings of operating system Notifications BB10 for my application. How to get javascript code if alerts permission is on / off, while the application is running.

  I tried adding the blackberry.system function and tried to hasPermission (blackberry.push) also, I can't determine if permission is allow / prohibit... Please suggest how to get that.

  I don't see a WebWorks API for this. If I expected to be anywhere, it's here:
  https://developer.BlackBerry.com/HTML5/APIs/beta/BlackBerry.notification.html#jbo1385148829097

  But it seems that this API has not been fully implemented; It may be useful to connect a developer Issue Tracker JIRA to get this feature added.

  At the same time, there is this API of Cascades that looks like what you're looking for:
  https://developer.BlackBerry.com/native/reference/Cascades/bb__platform__notificationapplicationsett...

  Write an extension for this feature should allow you to access this feature:
  https://github.com/BlackBerry/WebWorks-community-APIs/tree/master/BB10-Cordova/template

  At the same time, a colleague is currently working on an extension that should open many features of Qt, and I think that the API above should be accessible through this extension. He must be released over the next week or two, so you can wait for that as well.

  EDIT: On this last point, see this extension which provides a mechanism for attaching in the majority of the Qt APIs.

• Multiple selection with binding variable error

  Hello world

  I tried to put in place an array of adf multiple selection with another table, by following the tutorial (http://www.oracle.com/technetwork/developer-tools/adf/learnmore/75-multi-parent-row-detail-views-328078.pdf), page 3.

  I created all things and first of all I had an exception error, which I fixed, but now, whenever I try to select multiple lines, it won't update the table of the adf.

  In this example, I choose a service line and it shows the emplooyes, but every time I try to choose another line by ctrl clicking on it, the employees table be updated.

  Since I tryied to follow the tutorial, I'll put the code for the bean, I created for this purpose (it's a little different than the code given by the tutorial, but only because I had to get rid of the exception error)

  I use jdeveloper Studio Edition Version 12.1.2.0.0.

  Here is my code for the bean.java:

  Select listen port defined for the departments table. The selected line keys are read in the reference table.

  For each line, the Department ID value is read and added to a string buffer that generates a comma-delimited

  List of the departmentIds. In the end, this string is passed as an argument to the link of action ExecuteWithParams

  {} public void onDepartmentTableSelect (SelectionEvent selectionEvent)

  variable to hold the string containing the selected set value line departmentId

  StringBuffer departmentIds = new StringBuffer();

  Go to the main table to read selected line keys

  RicheTableau rt = selectionEvent.getSource ((richeTableau));

  RKS RowKeySet = rt.getSelectedRowKeys ();

  Iterator selectedRowsIterator = rks.iterator ();

  memorize the current line to place it back in the end key

  CurrentRowKey () rt.getRowKey = (list);

  for each selected master line, determine the departmentId

  int size = 0;

  {while (selectedRowsIterator.hasNext ())}

  size ++;

  The rowKey () selectedRowsIterator.next = (list);

  each value is terminated by a comma

  If (departmentIds.length () > 0) {}

  departmentIds.append(",");

  }

  take the current line

  rt.setRowKey (rowKey);

  JUCtrlHierNodeBinding wrappedRow = rt.getRowData ((JUCtrlHierNodeBinding));

  Line rw = wrappedRow.getRow ();

  /*

  Number departmentId = (number) rw.getAttribute ("DepartmentId");

  */

  int departmentIdInt = rw.getAttribute ("DepartmentId") (Integer);

  oracle.jbo.domain.Number departmentId = new oracle.jbo.domain.Number (departmentIdInt);

  departmentIds.append (departmentId.stringValue ());

  }

  back the foreign currency on the line

  rt.setRowKey (currentRowKey);

  Run the query on the detail table

  BindingContext bctx = BindingContext.getCurrent ();

  BindingContainer links = bctx.getCurrentBindingsEntry ();

  OperationBinding executeWithParams = bindings.getOperationBinding("ExecuteWithParams");

  executeWithParams.getParamsMap () .put ("departmentIds", departmentIds.toString ());

  executeWithParams.execute ();

  refresh the detail table

  AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance ();

  adfFacesContext.addPartialTarget (employeeTable);

  }

  }

  If someone has an idea of why it isn't updated table, please answer. Any idea can help.

  Thanks in advance.

  Greetings,

  Frederico Barracha.

  Finally, I found the problem...

  The problem was that I had to remove a line in the properties of my table, the property services: selectedrowkeys, because he only spent the last selected row.

  Yet, I apreciate the help and I had to replace a code in the bean.java, in reason of the exception error and you had to do. Maybe I did a configuration in the wrong way and he would not.

  Thanks for the help.

  Kind regards

  Frederico.

• questions about dps professional edition

  Hi, I would like to make you a few questions.

  I develop a digital magazine for a client, and I have to carry a magazine of Pentecost one release every 3 months.
  So I would like to know if it's better for me is a professional monthly or annual edition.
  That means, for the monthly professional edition, 250 folio download a year? And many consider each magazine version or just one? (I want to say, 250 download for each new magazine version 4 per year)

  If I download the version number 251, what will happen?

  Another question, if I subscribe monthly edition, the version number 3, will disappear after the month I paid?

  Thank you and sorry for the bad English!
  Andrea

  For examples of simple editing, you can take a look at Adidas Outdoor, for professional, take a look at loop Magazine, Magazine etc. blades. The diferrence major that you will notice is that with editions Professional, Apps have the ability to post multiple questions in an application, so it didn't need to introduce the new application to Apple and get it approved, whenever you have a new version of the question, with simple editing on the other end, each issue would be built in app, and whenever there is a new question/version will be submitted to Apple for review. Also with Professional Edition, you have an option to publish on the kiosk, Amazon, Android, iPhone. While the only edition is currently only available for the iPad.

  Thus, according to your priorities, decide that for yourself.

• Cannot see the data of the model within inline ItemRenderer in Spark DataGrid

  I'm having a problem displaying the model data in an ItemRenderer, online in a Spark DataGrid

  Here is the code for the DataGrid control

  < s:DataGrid id = "moduleDG" includeIn = "HomeRequired" x = "20" y = "116" width = "764" height = "404".

  " click =" DGchangeHandler (event) "dataProvider =" {model.items} ">

  < s:GridColumn id = "myModuleName" dataField = "moduleName" headerText = "{model.ui_nameColumn_str}" / > "

  < s:GridColumn id = "myEnterColumn" dataField = headerText = "{model.ui_actionColumn_str"launchActionText"}" >

  < s:itemRenderer >

  < fx:Component >

  < s:GridItemRenderer >

  < s:Button label = "{parentDocument.model.ui_nameColumn_str}" / > "

  < / s:GridItemRenderer >

  < / fx:Component >

  < / s:itemRenderer >

  < / s:GridColumn >

  < / s:ArrayList >

  < / s:columns >

  < / s:DataGrid >

  In the "inline" without the parentDocument reference ItemRendered, I get an 1120: access of undefined property error model. If I use outerDocument I get 1178: any attempt to access the property model inaccessible through a reference with static type error. I don't know what I should use here...

  The next column has no difficulty to display the property of model.ui_nameColumn_str - I understand the issue around scope and view the correct instance, I don't know how to get the model of the inline ItemRenderer. (We use simplemvc)

  Thank you

  Model must be a public variable, then outerDocument should work.

• Question about Threads with WHILE and FOR

  Hi all
  
  I have a question on threads with a loop on this topic sentece.
  
  Have the following class:

  class test{
  
  bool foundThing;
  PararellSearch(string [] lista, string s2find){
  while(!foundThing)
  {
  for(int i=0;i<lista.length;i++){
  if(s2find==lista){
  
  foundThing = true;
  
  break;
  
  }
  
  }
  
  }
  
  }
  If I start 10 threads which are using the PararellSearch method to look into lista, each of them inits into a different point, and when some of them found the right word then set foundThing= true. It will stop WHILE and FOR loop in all the threads? 
  If not, how could I do it?
  
  Thanks a lot for your help.

  When you post the code, you'll want to post a [url http://sscce.org] NBS so that it is clear that what you try to do it. For example:
  1. in the validation of code, put {code} before and after him, then he will be readable.
  2. the convention in Java must start with a capital letter class names, so test, could not test.
  3. the convention in Java is to start with lowercase letters, so parallelSearch, not PWhateverMisspellingYouHaveThere method names.
  4. There is no such thing as bool. It is a Boolean.
  5. it is a String, not string.
  6. never use == to compare the States of objects (such as the content of the strings). Use equals().
  To answer your question: If you create Test 10 objects, then, given that foundThing is an instance variable, there will be 10 variables entirely independent foundThing. An adjustment will not affect the other. In this case, the easiest thing to do would be to foundThing static, so that there is only one copy which is shared by the Test class as a whole. This isn't the only way, or even the best way in all cases, but you have enough other problems to face, so for now to keep things simple.
  Finally, when you have a variable that is shared by multiple threads, you need to either make all the access to this variable synchronized on the same lock (reads and writes), or you need to declare the volatile variable.
  		   

• Spark Datagrid columnheader click

  Hello!

  With the next Eventlistener I can detect a click on the Spark Datagrid header.

  dg.sortableColumns = false;
  dg.columnHeaderGroup.addEventListener (MouseEvent.CLICK, headerClickListener);
  ……………..
  Event handler header
  private void headerClickListener(event:MouseEvent):void {}
  Alert.Show ("something");

  But how do I detect the current column of the user clicked Headeritem?

  In my view a Build-In Header-Click-event and a Build-In Columnlocking is a "Must Have" of a professional Datagrid.

  Will there be a Flexupdate with a Datagrid improved spark in next time?

  Greetings

  Uwe

  Instead of listening for the GridEvent.GRID_CLICK event. The GridEvent will be the index of the column in it. We return all the events of the mouse on the DataGrid as GridEvents.
