• How to get the current location in the event thread?

  Hello!

  Can U pls tell me how to get the location where the thread object, it is in method() execution of MenuItem. PLS, tell me-

  I also used the different thread for the getLocation() method. But I do not have the coords of geo location...

  PLS, suggest me-

  My code is as below:

      private MenuItem getGeoCodes=new MenuItem("Current Coords",100,1){
  
                               public void run(){
                                   double[] coords=getLocationCoords();
                                   this.wait(12000);
                                   System.out.println("Latitude :"+coords[0]+" "+"Longitude:"+coords[1]);
                               }
  
                   };
  
      private double[] getLocationCoords(){
          Criteria criteria = new Criteria();
          criteria.setHorizontalAccuracy(500);
          criteria.setVerticalAccuracy(500);
          LocationProvider locationProvider = LocationProvider.getInstance(criteria);
          Location location=null;
          new Thread(){
             public void run(){
                     locationProvider.getLocation(60);
             }
          }
          QualifiedCoordinates qualifiedCoordinates=location.getQualifiedCoordinates();
          double[] coords=new double[]{qualifiedCoordinates.getLatitude(),qualifiedCoordinates.getLongitude()}   ;
           return coords;
      }
  

  But I myself NullPointerException. Coordinates get successfully, if we run the location capability in different function, rather than the event thread.

  Please help me-

  In my opinion, which may be too complicate things a bit. I think he's trying to do is register a LocationListener with his object of LocationProvider. Callback methods, send a message to the UI event thread as follows (no need to spawn threads):

  UiApplication.getUiApplication().invokeLater( new Runnable() {
      public void run()
      {
          // This code will execute on the event thread
      }
  });
  

  EDIT: If your interval is short, you can consider implementing this executable as a class and store an instance in the front.

• How to get the web client to refresh its point of view of the deployment of openstack

  Hello

  I had a problem with my MariaDBs which caused Violence to fail to start after his stop. The webclient service displays a message that failed "bootstrap" and newspapers showed that the databases where failing to start. I got data bases and went 'vioconfig start' of the converted VIO openstack starting towards the high fine. IM able to connect to the dashboard and perform all tasks as before so, everything seems to work very well. However the webclient service always shows VIO in a State with the "bootstrap" of initial start error and error. How can I get the webclient service to acknowledge that Violence now is working well?

  Hello

  Here are the steps to synchronize the user interface with the backend.

  1 > please use the user interface to start and stop the Openstack and avoid using CLI tool (because the tool doesn't have sync the database)

  2 > if you do not have to use the user interface to start the deployment (generally, it was caused by the inconsistent database), then you can manually recovered databases.

  3 > using the method as Arvind suggested but instead of changing the status of 'RUNNING', please change it to "STOPPED".

  4 > then come to the user interface to use the user interface to start the cluster.

  Hereby you will have everthing sync upward.

  Kind regards

• How to get the selected tree node and its attributes

  I have a 'af:RichTree' on a page, which is linked to a support bean (session scope)
  
  Here is my selection Listener:

• How to get the component custom property

  I have a custom component that is repeated as follows:

  "< mouseOver =" CFSMouseOver_Folder (event) "local: ComFolderItem" click = "CFSClick_Folder (event)" studentName ='{productsRepeater.currentItem.productName + "(" + productsRepeater.currentItem.productPrice + "") "'}" > "

  I think you would be after something like:

  }

• How to get the static attribute by using its name as a string

  I have an app with about 100 boxes of single drop-down list (this is a requirement of the Government, I'm not that bad a designer) and I would like to define the choices in a single file separated like this:

  package components {}

  Import mx.collections.ArrayCollection;

  public class {choice}

  [Bindable] public static var A0310A: collection ArrayCollection = new ArrayCollection ([] collection
  {value: '01', label: 'Admission'},
  {value: "02", label: "Quarterly"},
  .. .snip...
  ([{value: "99", label: "NOT the OBRA required"}]) ;
  
  public static void getChoices(name:String):ArrayCollection {}
  var temp: ArrayCollection = collection?
  Return temp;
  }
  
  }//----------------end of class--------------------------------
  }//======================== end of package==============================

  I want to use it like this

  < my: ComboBox id = "mdscombo" tag = "A0310A" / >

  Where the definition of my: ComboBox includes the code like this

  var zz:ArrayCollection = Choices.getChoices (name);

  but I can not find any function that will allow me to do.  I don't want really clutter up the code by creating a name-> object mapping table.

  I had also considered using the XML data type, but I have the same question, unless I had all the choices under a single root (possible), but this could be a nightmare when debugging in typo XML file.

  Any suggestions?

  To answer your question, you can access static variables with a chain in this way:

  Choice ["A0310A"]

  However, you probably want to re-evaluate your design because this isn't a very desirable approach.

• How to get the RGB color values on the color picker component?

  How to get the RGB color values on the color picker component?

  trace (cp.selectedColor);

  Returns something like:

  16750950

  trace (key2cp.hexValue);

  Returns:

  ff9966

  I'm looking for RGB, for example, 0.5 0.5 0.5, corresponding to a gray color.

  Is there a chance that the RGB settings are hidden somewhere or is there a conversion function at least?

  Thank you.

  If key2cp.hexValue returns a string like 'abcdef', use:

  var s:String = key2cp.hexValue;

  var n: Number = Number("0x"+s);

  var r: Number = n > 16 & 0xff;
  var g:Number = n > 8 & 0xff;
  var b:Number = n & 0xff;

• How to get the property of the image on the width and height?

  Hi, all, I import image from the outside with the following method, but how to get the w3c_main.png on the width and height property? I will appreciate for your answer.
  
  var mcLoader = new MovieClipLoader()
  mcLoader.loadClip (" http://www.w3.org/Icons/w3c_main.png", image);
  
  or an image. LoadMovie (" http://www.w3.org/Icons/w3c_main.png")

  in the first case use the method onLoadInit() to a listener for your mcl before trying to access your target movieclip laborious and _height properties.

  in the second, use the preloader code to ensure your png loading is completed before attempting to access the _width and _height of your target movieclip properties image.

• How to get the bar display of title in pixels text length?

  Hello

  Does anyone know how to get the length of the title bar text (in pixels) display?  Just to clarify, that's what I'm looking for:

  

  I don't see a CVI function for this.  The attribute ATTR_TITLE_FONT for GetPanelAttribute (...) is only valid for the panels of the child which prevents me from using the GetTextDisplaySize (...) to get the size.  Dive into the Windows SDK I can not even find an answer here.  Any ideas?  Thank you.

  Figured out how to do this.  Go to the SDK to get the font properties - is kind of nonobviousness.  But once you have the font properties, you can create a font of meta in CVI, with properties, and once you have the meta font you can use GetTextDisplaySize (...) to get the size.  For any future reference:

  //define a NONCLIENTMETRICS structureNONCLIENTMETRICS ncmtest;//We have to set the cbSize parameter to the size of the passed structure before retrieving it
  ncmtest.cbSize = sizeof(NONCLIENTMETRICS);
  //Get NONCLIENTMETRICS structure
  result = SystemParametersInfo(SPI_GETNONCLIENTMETRICS, 0, &ncmtest, 0);
  
  //copy the title font name to a c-string
  while(ncmtest.lfCaptionFont.lfFaceName[i] != 0)
  {
      thefont[i] = (char)ncmtest.lfCaptionFont.lfFaceName[i];
      ++i;
  }
  
  //null terminate
  thefont[i] = '\0';
  
  //create meta font with title font properties.  lfWeight & 0x700 indicates bold.  CreateMetaFontWithCharacterSet() doesn't recognize DEFAULT_CHARSET so we replace it with VAL_NATIVE_CHARSET(?).
  uir_status = CreateMetaFontWithCharacterSet ("TheTitleFont", thefont, abs(ncmtest.lfCaptionFont.lfHeight), ncmtest.lfCaptionFont.lfWeight & 0x700 ? 1 : 0, ncmtest.lfCaptionFont.lfItalic, ncmtest.lfCaptionFont.lfUnderline, ncmtest.lfCaptionFont.lfStrikeOut, 0, ncmtest.lfCaptionFont.lfCharSet == DEFAULT_CHARSET ? VAL_NATIVE_CHARSET : ncmtest.lfCaptionFont.lfCharSet);
  
  //get titlebar text
  uir_status = GetPanelAttribute (panelhandle, ATTR_TITLE, thetext);
  //get title bar length
  uir_status = GetTextDisplaySize (thetext, "TheTitleFont", &height, &width);

• Questions regarding the process of implementing container/control. How "parent of filling" and how to get the actual size of the control?

  I'm writing some UI component custom waterfalls. I went if the document several times and still have two questions:

  1. is it possible to adjust the width of the control to fill the container parent without specifying the number hardcoded in pixel? I see many example of code uses '768' as hardcoded width.

  2. I understand that the 'preferred size' could be ignored in some cases. Is it possible that I can get the actual size of the control on the screen programmatically?

  3. is there any signal was issued when a control container/finish covering all of its child nodes? How do I know what size of a control is finally decided?

  Thank you

  mdodd wrote:

  (1) you can use (QML)

  horizontalAlignment: HorizontalAlignment.Fill
  

  or (C++)

  myControl->setHorizontalAlignment(HorizontalAlignment::Fill);
  

  This will cause control occupy the entire width available to its parent. However, keep in mind you may have to use this property on all containers of parent to the node root to get the width of the full screen.

  As far as I KNOW simon_hain is located on the other two issues.

  ((2) & (3) I just dug around and you find LayoutUpdateHandler would do the job:

  https://developer.BlackBerry.com/Cascades/reference/bb__cascades__layoutupdatehandler.html

  mdodd answer on question 1) is correct.

  I can't believe they made a separate category for such a common task. Framework of stunts have had some serious consistency problems, that's what I feel.

• How to get the physical size of the screen?

  Hi all

  How to get the physical width and height of the screen (not resolution) in inches or in centimeters?

  Is there a method to do

  Thank you very much

  Display.getWidth () and Display.getHeight () you will get the number of pixels.

  Display.getHorizontalResolution (); and Display.getVerticalResolution () to get the pixels per meter.  Then by dividing appropriately you can find the actual size.

• How to get the actual size of control?

  How to get the real size control when the preferred width/height is not defined but control have size which are automatically evaluated (for example contaier with the disposal of the battery)?

  Try the LayoutUpdateHandler: https://developer.blackberry.com/cascades/reference/bb__cascades__layoutupdatehandler.html
