Custom DataGridColumn sends the data to the ItemRenderer

I use the as3 syntax to create a few advancedDataGridColumns and specify to use cusItemRenderer

by "col.itemRenderer = itemRenderer;". ""

I have replace the function set the ItemRenderer in the class of AdvancedDataGridColumn customed.

But the itemrenderer is unable to get the data.

Is there anyway to get the 'datafield' and 'headerText"DataGridColumn properties in the itemRenderer?

This is my code:

/ / I create an ItemRenderer to pass to all DataGirdColumns

var itemRenderer:cusItemRenderer = new cusItemRenderer();

/ / I create some columns

Col = new AdvancedDataGridColumn (flatColumns [i]. Label);
col.dataField = "@" + flatColumns [i]. Field;

col.itemRenderer = itemRenderer;

public class cusAdvancedDataGridColumn extends AdvancedDataGridColumn
{
override public function set itemRenderer(value:IFactory):void {}


var itemRenderer:cusItemRenderer = value as cusItemRenderer;

itemRenderer.parentField = this.dataField;
itemRenderer.parentLabel = this.headerText;


super.itemRenderer (itemRenderer);

}


}

public class cusItemRenderer extends AdvancedDataGridItemRenderer implements IFactory
{

/ / They are always null ~!
public var parentField : String = null;
public var parentLabel : String = null;

function public newInstance(): * {}
return new cusItemRenderer();
}

}

The itemrenderer set went from an Ifactory, not the actual converter class

or an instance.

If the rendering engine implements the IDropInListItemRenderer, it should have a

property columnIndex in the listData which can be used to find the column.

  • Custom theme lose the buttons send in the quiz

    Hello

    I have a theme that I made for a customer and only altered slide masters they used. The button publish (with the keys skip etc.) are all there in the master slide, and they show on every slide of issue they have, but when I click on preview this slide, or publish, as soon as you get to the quiz, there is not button Submit. The theme projects have been created on a computer and uploaded to a Google Drive folder. The customer has bought the Captivate and uploaded files (originally it did not download the theme, but has since begun from scratch - downloaded again any project and theme) of the reader, edited and sent them back. When I opened the projects, quiz slides and slides model has the Submit button, yet project overview (or editing by the way) are not there send buttons.

    I think it's a matter of topic, but I can't understand what is happening. The project has only been to Captivate 9 I know - the customer has recently purchased Captivate, and my version is up-to-date.

    Interestingly, I changed the theme to a standard embedded theme of Captivate and the Send button appears in the preview of the question slides. Should I create another theme from scratch, and then import it to each project? What went wrong initially - if it was the fact that he had not downloaded the theme I think which would break things, but then it picked up completely from scratch. Is there a difficulty without creating a new theme from scratch? PreviewExample SlideMaster

    Since the buttons send return when you change the theme to one of the standard ones found in Captivate, I would say that you definitely need to recreate your custom theme.

    I don't know what was wrong originally.  Captivate would not have worked at all for your customer unless there was at least some basic default themes, it can access.

    Now, the important thing is that you get an another theme created.  One of the other default themes Captivate is to base on.  The empty theme is generally offered for it, but there was a reported issue last week on the forum on this topic, then perhaps choose a different this time out.

  • Sends the data backend Java

    What is the best way to send a flex object to a java backend and then do something about this on the server? I have a table that contains a custom class. When the user clicks on send, I want to send the picture to Java, then get the content of the table to handle the content and write it to a file.

    I have a remote Java object I want to send the data, in order to manipulate it. I don't think that I need a remote object to represent the purpose of flex, but because that would mean that whatever changes I do object in flex continually is sent to the back-end right? I want to just send it in one appointment once the user has finished editing on the front-end server.

    I found XML serializers that people did that recursively go through the object and create XML. It must then be deserialized on the coast of Java. I thought that there must be an easier way. Is there a library or something for this?

    Perhaps, I do not understand the reason for your implementation so don't take no not this personally.  But why would you send a Canvas object, which is part of the view on the server?  If you are only wanting to send the data contained in the text to the server for processing objects you want to do is create a ValueObject (TransferObject for some) and send it to the server, as well as perhaps instructions you want to send.

    On the other hand (and this is just a blind guess at what you're trying) If you are wanting to send the objects so that you can implement some sort of compilation side server, then you want to send the object to plain text for the Web as one of the settings contained in your ValueObject.  Alternatively, you can use Adobe AIR and zip all of the defined object and send the file to the server where it can be decompressed and compiled.

    Here is a blog post on data transfer between Java and Flex using RemoteClass.

  • Pdf forms can always send the xml data (even if the pdf does not extend)?

    Hello

    My problem is the following. I have Acrobat Professional license, so I can create pdf forms.

    I added a shipment through the mail button to my form and sent to the end user, who had only the acrobat reader software. He was able to complete the form and send its data via the e-mail button, and I got an xml with the data file.

    Because I had not extended the document, I suppose it's always possible, so I can always receive the xml data in completed forms, I can't?

    Then also extended the professional Acrobat document (Tools-> enable usage rights in Adobe Reader), because I need the final customer, be able to save the form. Now, I just sent this document extended by mail (do not use the tool Distribuite form in Acrobat), the user has clicked the button and again once I received my xml.

    Now, I want to back my document to a maximum of 500 customers, I have no limitation?

    I quote acrobat licenze agreement:

    14.13.3 for any unique Document extended, you may only either (a) deploy this Document extended to an unlimited number of recipients unique but shall not extract information from more than five hundred 500 unique of this extensive Document instances or any representation of a paper copy of this Document extended with fields of form [...]

    Since the function I described before (the xml data emailing) is granted even if the document is not extended, I think that this limitation does not apply to me. Am I wrong?

    The limitation applies instead if I use the function 'Distribuite form' (forms-> Distribuite forms...) in acrobat professional. If I use this feature for distribuite the form, an email is automatically sent by acrobat (and not manually by me, as before) and pdf dataset is created. When the end customer cliks button, a pdf file (and not an xml) with the data are sent to me. If I double click on acrobat fills the dataset that was created with the data. It is the extraction of information to which the license relates?

    This is my conclusion: a pdf form can still send data xml by the player, and if I Express with acrobat, the end-user can also record. The only restriction is to distribute the form using "Distribuite form", but if I use it not I have no limitation on the number of times where ever I can get xml data.

    Can anyone confirm that my conclusion is just?

    Thank you very much

  • Why convert? What is the advantage? Why convert it before you send the data over the network?

    Hello everyone.

    I have a question quite simple and intuitive. Yet Google does not seam to get the answer.

    Basically, I'm curious why should we catalogued something? It seems to me that it's just a little like a "band-aid" for editing data in conversion to a new data type, when it is not properly declared with an appropriate data type. What would be the advantage of this?

    Furthermore, I see a lot of data type casting to U8 programs before sending it over the network. Various reviews say it's for speed, but I can't understand how it improves speed. The same amount of data is still sent, just in a different type of data. This is overcoming a limitation of the network. The network somehow send smaller data types faster?

    I've been curious about this for a while and have yet to find an answer. Any help is appreciated.

    Thank you

    It really depends on the specific situations.

    For example, some functions explicitly require certain types of data as inputs if they are not polymorphic.

    This means that if you do not convert the data yourself and you will see a red dot forced LabVIEW will do it for you.

    As to why the data was not the correct data type in the first place, it is sometimes inevitable.

    A few examples

    -What happens if you just read a text file as a long string.

    If there is digital data in this file, you need to analyze, and then convert it to a usable type (int, sgl, dbl, etc.)

    -you are given a 3rd part VI, dll, etc. that returns a numeric value as a double, but you need the value to I8.

    You cannot change the output of the function given to you, so what you can do to remedy this situation is cataloged data.

    Somehow, this is my first response, but in a more general sense.

    Many functions down to the level of the OS run in binary.

    If your data are not already in binary, the sending computer must convert it to binary, and then send it, have the receiving computer convert in return.

    Two conversions on each side of the transmission add unnecessary delays.

  • TCP Comm send the Hex data

    I have an embedded device server that has a controllable set of 8 pins of the user. The format of order for these pieces requires a TCP message which is 9 bytes long and hexadecimal.

    I use TCP Communicator - Active .VI in the LV7.1 examples, make a link to the server of the device. There is no problem with the connection - but I'm unable to send the message in HEX format.

    The transmitter/receiver always converts my entry into ASCII and the command fails so. Also, he fragments the typed command bytes and when I probe the resultng with a network Analyzer (Ethereal) data package I see that the VI has fragmented the bytes of data in several discrete packages.

    The order message I want to send is in this format: FF 00 00 00 FF 00 00 00 1B

    Any suggestions to solve the problem?

    Thank you

    You must either create your string in hexadecimal display mode so that you know that you enter hexadecimal values, rather than characters, or use a byte array, and then use the function to the array of bytes to a string . I would opt for the latter because it is easier to understand.

    Note that the table is an array of integers of U8 whose formatting the hexadecimal value, and using a field width minimum 2 characters, zeros on the left and with the radix displayed. Makes it more clear that this is a hexadecimal value.

  • using PIN messages to send the query and return data

    I am working on an app that will send a request to another blackberry and return the data all via PIN messages. There is a user interface where the user selects the contact and start the PIN message with the request. There is a background application that listens to these requests. When we arrive, he must inform the user and allow them to send the requested data or reject the request. If they choose to send, it will undertake a PIN to the sender with the requested data, which will then be returned to the screen. Is it possible by using PIN messages, and if so, can I prevent their display in the list of messages?

    If you are referring to record and send after filling out a form, you can either use an Adobe Reader or Acrobat application.

    Adobe Reader is a free service and you can install it here: Adobe - Adobe Acrobat Reader DC Distribution

    The bells?

    You're right - the customer hung up before the server was able to send a response to him. In this case, the server has received the request of the customer and customer was waiting for an answer from him. The duration for which the customer is waiting for a response from the server is set by the customer read-timeout parameter.

    In addition, it is worth looking at why the server sometimes (not always) take so long to answer. If some function calls to take more time? In this case, read-timeout to the customer must be increased to take account of this possibility. Or is that sometimes something happens in the server which makes it insensitive? Your previous question, I was just looking at that comes to mind here - in this case the culprit was a break from GC. This problem may be caused by a break from GC as well.

  • Flash builder 4.6 - send batch data to the server (php connected)

  • How can I access all instances of the itemRenderer in a specific DataGridColumn?

    How can I access all instances of the itemRenderer in a specific DataGridColumn? Or, if I have a rowIndex and columnIndex, how do I get the itemRenderer to these clues?

    I use States to change the display of my itemRenderer of a TextField of a PopUpMenuButton. What I was trying to do was change back the display of all the other itemRenderers visible in the column of the textfield, when one of the itemRenderers displays the PopUpMenuButton.

    I tried to loop through all of the itemRenderers in the column and casting them as the class I was using and then by setting the currentState, but, it wasn't good performance wise and required too code. I simplified it listen to a change on the listData owner event (in my case a DataGrid, but any component ListBase) and by setting the currentState to null when it is triggered. Works like a charm.
