• Flex Mobile: View parent access within the itemrenderer component Variable

  I have several images in a list and I want to display 4 of them both on the screen with a provision in mosaic with the width of each image = 50% of the height and width of screen = 50% screen height.

  I was able to do this with the code below.

  < s:List id = "list1" width = "100%" height = "100%" >

  < s:ArrayCollection >

  < fx:Object id = "img1" img_url = ' assets/1 - 1.png' title = "Image 1" / >

  < fx:Object id = "img2" img_url = "assets/1 - 2.png" title = "Image 2" / >

  < fx:Object id = "img3" img_url = "assets/2 - 1.png" title = "Image 3" / >

  < fx:Object id = "img4" img_url = "assets/2 - 2.png" title = "Image 4" / >

  < / s:ArrayCollection >

  < s:layout >

  < s:TileLayout

  columnAlign = "justifyUsingWidth" horizontalAlign = "center" verticalAlign = "middle".

  paddingBottom = paddingLeft '0' = '0' paddingRight = paddingTop = "0" "0".

  horizontalGap = "0" verticalGap = "0".

  / >

  < s:itemRenderer >

  < fx:Component >

  < s:ItemRenderer >

  "< s:Group width ="160"height ="240">" "

  < s:BitmapImage source = "{data.img_url}" scaleMode = "stretch" smooth = 'true' "

  < / s:Group >

  < / s:ItemRenderer >

  < / fx:Component >

  < / s:itemRenderer >

  < / s:List >

  However, I don't want to hard code the width and height values.

  I am able to get the screen specify height and width in the event viewAcivate of the view, as shown below.

  protected function view1_viewActivateHandler(event:ViewNavigatorEvent):void

  {

  ScreenWidth = screen.width;

  ScreenHeight = screen.height;

  }

  How to apply these values for width/height of the group properties in the itemrenderer?

  Something like...

  < s:ItemRenderer >

  "< s:Group width ="{ScreenWidth/2}"height ="{ScreenHeight/2}' > ' "

  < s:BitmapImage source = "{data.img_url}" scaleMode = "stretch" smooth = 'true' "

  Width = "100%" height="100%"/ >

  < s:Label text = "{data.title}" left = low "0" = "0" width = "100%" / > "

  < / s:Group >

  < / s:ItemRenderer >

• How to use methods within the itemRenderer

  Hello
  
  I have basic itemRenderer as a component:
  
  < mx:Component id = "ColorRenderer" >
  < mx:Label
  Text = "{rgb2hex (255,100,50)} ' / / this gives error: 1180: call to a method may be undefined rgb2hex"
  / >
  < / mx:Component >
  
  My method works if I use it with a 'normal' tag < mx:Label = "22" x = "12" text = "{rgb2hex (255,100,50)}" width = "150" / > "
  but it does not work inside the itemRenderer?
  
  What I'm missing here?
  

  When you use the tag you define a new variable scope. In this context, the rgb2hex does not exist. You need to qualify: { outerDocument.rgb2hex (255,100,50)}

• Trainer to date within the ItemRenderer list...

  I am trying to format the date timestamp of a mySQL database that I display within a list in a mobile application. The trainer also works perfectly... However, when I call in the item list converter, no dice... I'm sure it's a syntax error, but I don't seem to be able to understand:

  Here is my IconItemRenderer for the list:

  <s:IconItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" 
                      xmlns:s="library://ns.adobe.com/flex/spark"  labelField="displayLongDTF.format(date)" 
                      messageField="username" iconWidth="32" iconHeight="32" decorator="@Embed('assets/button-help-32x32.png')" >
  </s:IconItemRenderer>
  

  Here's my decleration of rendering engine:

  <s:DateTimeFormatter id="displayLongDTF" dateTimePattern="EEE, MM / dd, yyyy h:mm a"/>
  

  And when I run... It is simply void where the date should be...

  Yes, you need something like this:

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

  xmlns:s = "library://ns.adobe.com/flex/spark".

  labelFunction = "dateLabelFunction."

  ... >

  private void dateLabelFunction(item:Object):String

• How to get individual columns within an itemrenderer?

  Hey,.

  I was wondering if it is possible to get the column of a datagrid in an itemrenderer? I have a datagrid with 4 columns. I would use an itemrenderer for each of them. Is it possible within the itemrenderer which gets the individual column for me. For example

  ItemRenderer:

  DataGrid1 = datagrid (parentDocument as file name);

  If (datagrid1. "selectedColumn"(==0) {} "

  doThis();

  }

  If (datagrid1. "selectedColumn"(==1) {} "

  doThat();

  }

  Is something like this?

  Thank you!

  If your converter implements the IDropInListItemRenderer, you can figure out the column that you represent by examining the listData property

• Integrated within the DataGrid item renderer.

  Hello

  Please find the page attached with this thread.
  The data are filled in the DataGrid to database using ArrayCollection as a DataProvider collection.

  Now, I want to have the Radio buttons displayed at the begning of the each row of the column names.

  
  When I tried to use, itemRenderer integrated as mx.controls.RadioButton inside DataGridColumn column "Names" of DataGrid, data appeared so that all the data within the column names is replaced by showing only option button.

  Please tell me if this is possible using integrated point rendering itself? (As custom rendering seems difficult for me rigjt now)

  Or suggest me an easy approach, basically, my requirement is I want to get the selected value in a function object to do the installation Upadate and Delete.

  Help, please

  
  Thanks in advance.

  You use the set for cyclesValue method incorrectly.

• data not passed to the ItemRenderer

  Because my itemrenderer is not working properly when scrolling, I wanted to use ' override public function set data(value:Object):void "so he can show the appropriate image. But I found that it is not called. So I tried a track on data.removable (I know for sure that this value exists) to the inside of my itemrenderer component and apparently data = null.
  I have no idea why it is not be transmitted. Until now, I just forwarded the data inside the element with the datagrid to a public string within the element.
  
  

  Corrected it as follows:

  Main component with datagrid (snippet):

  Component with the itemrenderer (snippet):

  private function checkIfRemovable (): void
  {
  If (removable) / / check if it has helped remove
  {
  This.source = Vars.rooturl + "images/delete.gif";
  this.toolTip = 'delete project ';

  this.addEventListener (MouseEvent.MOUSE_OVER, MousePointers.showHand);

• What is a substitute for the migration assistant? I tried in vain for three hours to migrate files from a macbook pro to each other so that even if connected with the ethernet cable the computers never see each other.

  What is a substitute for the migration assistant? I tried in vain for three hours to migrate files from a macbook pro to each other so that even if connected with the ethernet cable the computers never see each other.

  You can connect otherwise?  USB or FireWire or love at first sight?  You can connect both machines and start the one you want to transfer to target disk mode.  If your other machine is up and running with an account on it and you just want to move files, you can simply drag and drop the FRO the machine mounted TDM, or you can use the migration wizard.

  Or, if the other machine still starts and runs, you can start both computers and connect to the same wifi network and share the hard drive like machines on the network.  Access them in the finder on the new machine files and drag-and - drop, or use the wizard migration, on wifi.

• Free app from Merriam Webster found within the Starbucks App

  Hello, the starbucks in messages app, it is supposed to be an application of Merriam Webster's dictionary for free (value of $3,99 otherwise). By starbucks, this free app is available until May 24, 2016. I have nothing in the messages. I deleted the app off my iphone for a few minutes, turned the phone back, re-installed the app, signed on my account of starbucks in the starbucks app and still nothing. I called the service customer starbucks, and they suggested that contact iTunes or the App Store for resolution. Can anyone help to understand why the dictionary app does not appear within the app from the SB?  Thank you.

  I suggest you contact the support for the app of Starbuck. He is not an apple product.

  I'm a convert from windows and love the mac but Alt - Tab within the application does not work - very annoying. I often have multiple windows in the same application, and if the only way to go is to use 4 fingers Mission control, it's terrible because Mission control lists all windows in a small size and pain to know that you want to go. While with alt - tab, I can quickly cycle or just go to the last which is often I want to go to.

  It is one of the major issues Mac usability for me.

• Read command line arguments to TestStand sequence start, moving within the sequence

  Start a sequence by using a batch file and add command line arguments. Example: "MySequence.seq Arg1.

  Now, within the sequence I want to read this first (and another) argument "Arg1".

  There is a stage in the ActiveX for that, giving a type (object reference) channels, see screenshot.

  Question: How to use this reference to read the argument?

  Honestly I don't think that you are using it correctly.  I think that your application in your UI Manager must handle this.  However, to answer your question:

  According to the TestStand help CommandLineArguments property is of type string.  It comes to aid of TestStand as well:

  Channels
  A collection of strings. You can get a reference to the collection of the ApplicationMgr.CommandLineArguments property, the ExpressionEdit.GetValidEvaluationTypes and ExpressionEdit.SetValidEvaluationTypes methods and the ApplicationMgr.ProcessUserCommandLineArguments event.

  Properties
  Count (read-only)
  Agenda

  Methods
  Add
  Claire
  Insert
  Delete

  Looks like you can use activeX not use Count or properties of the element to retrieve a single argument.

  Hope this helps,

• Structure of the event within the structure of the case run once

  Hi all

  I am a controller using myRIO and labview where the program compares a value of the probe in a "Preset" and then choose a structure case depending on what type of air supply is required. What can be seen on the picture, for example, is 0 if saturated air supply is necessary.

  The structure of the event is used to send a signal to step to the stepper motors to open the valves (closing is still pretty much in the same way). In any case, the event turns my valves 90 degrees. I read the sensor all a second, however, when the case remains unchanged, the case runs the event again causing my engines running at 90 degrees per second (essentially continuously). What I'm looking for is a way to send the signal to step only once until a new case is selected.

  He is not on the photo, but this is all within the large loop.

  Apologies for any bad/cringeworthy coding, it is literally my first program always using labview. I can post the full VI if you need.

  Any ideas would be very appreciated! Thank you

• deploy programmatically variable shared within the standalone version of RT (cRIO-9014)

  Hello

  I have a question about here to use variables shared single process within the standalone version of RT for the cRIO-9014

  I simplified my request of LV (LV2010) in two to test the use of shared variables.  See the attached file.

  (1) only run on the host PC: testHost
  (2) only works on the cRIO-9014: testRTcRIO

  for both, I packed stand-alone executable and source distribution.

  for testHost,.
  (a). I copied \builds\testcRIO\Host to d:/or-rt/xmlrpcFEU source Distribution...
  (b) I run... \builds\testcRIO\Host.exe
  (c) xmlrpcFEUlog - host.txt is generated.

  for testRTcRIO,.
  (a) .d FileZilla to connect to the target of RT on network, I copied... \builds\testcRIO\Source Distribution\c\ni - rt\xmlrpcFEU

  to/or-rt/xmlrpcFEU on the target of RT
  (b) I copied also... \builds\testcRIO\Real-Time Application\c\ni - rt\startup to/or-rt/startup on the target of RT
  (c) Max, I restarted the cRIO-9014.
  (d) xmlrpcFEUlog - RT.txt is generated.

  We see that the shared variable does not work inside the RT target. but worked well on PC. the deployment programmatically method does not work.  any suggestion?

  Another thing is:
  can I use telnet for the RT 9014 target and start the RT app directly? What is the command inside the terminal telnet RT?

  Currently, I can telnet into the cRIO-9014, but, what I can do with it?
