• How to create several classes of cascade?

  Goal: Create the button to start and stop the service.

  Situation: One button works.

  However, whenever I click on another button, the button does not work.

  Question: how to create several classes of cascade?

  or something wrong in my code?

  Mini code:

  Calls a CPP QML.

  ApplicationUI::ApplicationUI (bb::cascades:Application * app): QObject (app)

  {
  QmlDocument * qml = QmlDocument::create("asset:///main.qml").parent(this);

  CameraWrapper * wrapper = new CameraWrapper();

  QML-> setContextProperty ('wrapper', wrapper);

  AbstractPane * root = qml->() createRootObject;
  App-> setScene (root);
  }

  And then, QML calls another RPC.

  import bb.cascades 1.0

  {Page}
  {Of container
  layout: {DockLayout}
  }
  Button {}
  text: qsTr ("Start")
  onClicked: {}
  wrapper.startRec ();
  }
  }
  Button {}
  text: qsTr ("Stop")
  onClicked: {}
  wrapper.stopRec ();
  }
  }
  }
  }

  The main CPP:

  #include "cam.hpp".

  using namespace bb::cascades;

  {CameraWrapper::CameraWrapper()}

  int CameraWrapper::startRec() {}

  This button works.

  }

  int CameraWrapper::stopRec() {}

  This button does not work.

  }

  The main.hpp

  Class CameraWrapper: public QObject
  {
  Q_OBJECT
  public:
  CameraWrapper();
  Virtual ~ CameraWrapper() {}

  Q_INVOKABLE
  int startRec();
  int stopRec();
  };

  Thank you for your attention,

  Finally, we use the thread to solve the problem.

  Solution:

  loopWrapper (void * test) {void *}
  CameraWrapper * a = (CameraWrapper *) test;
  a-> startRec();
  return null;
  }

  setFlagWrapper (void * test) {void *}
  CameraWrapper * b = (CameraWrapper *) test;
  b-> setFlagFalse)
  return null;
  }

  void * CameraWrapper::setFlagFalse (void * arg) {}
  exit_application = false;
  fprintf (stderr, "Flag changed to false\n");
  return arg;
  }

  void CameraWrapper::runLoop() {}
  pthread_create (& thread_a, NULL, & loopWrapper, (void *) this);
  }

  void CameraWrapper::runSetFlag() {}
  pthread_create (& thread_b, NULL, & setFlagWrapper, (void *) this);

• How to create a (class dot Tag without spaces) tag.class via the window of Dreamweaver CS5 rule.

  How to create a tag.class via the window of Dreamweaver CS5 rule.  I want to create a class that affects a specific tag.  I can for this use the code window, but I'm trying to use the Style CSS window.  The tag that I create is 'ul.navbar.  I was able to be machined, but I get "ul .navbar", note the space between L and the period.  I want to remove the space and just create "ul.navbar", without having to rename.  The code will appear as:

  ul.navbar {
  position: absolute;
  width: 9em;
  left: 1em;
  top: 2em;
  list-style-type: none;
  }
  The question is perhaps more base on my understanding of CSS rather than Dreamweaver, if yes, I'm sorry.  I'm just starting to work with CSS.
  Thanks for your help.

  My point is that this is not the best way for the style of this element of the page in most cases.  However, if you create a rule made up, you can enter "ul.navbar" directly in the selector name field.

  Don't overuse of classes.  They confuse you in just a few weeks after you have modified looked at the site.

• How to create a class and a pointer to the Panel

  Hi all

  I'm new to Flex.  I created a dynamic group that has three children, added to it. The three children are Hbox and Vbox or an Hbox. The first Hbox with a label that should be updated every minute. I tried using getChildrenAt and it works and it seems .as Hack I'm doing like getChildrenAt (0) as Hbox, I have more than one group of experts and all the Panel must be updated values. So is it possible. I could create a class and has a pointer on the Panel and a pointer to the label, which will be called every minute and on the change of the label in the front of this update

  Thanks in advance

  Barro

  OK yes I think I understand now look to examples.  First heres my custom panel ELEMENT.

  package

  {

  Import mx.containers.Panel;

  Import mx.controls.Label;

  SerializableAttribute public class MyPanel extends Panel

  {

  private var _labelValue:String

  private var labelSet:Boolean;

  private var myLabel:Label;

  public void MyPanel()

  {

  Super();

  }

  public function set {labelValue(value:String):void}

  _labelValue = value;

  labelSet = true;

  invalidateProperties();

  invalidateSize();

  }

  public function get labelValue (): String {}

  Return _labelValue;

  }

  override protected function createChildren() (): void {}

  super.createChildren ();

  myLabel = new Sun;

  addChild (myLabel);

  }

  override protected function commitProperties (): void {}

  super.commitProperties ();

  If {(labelSet)

  MyLabel.set_Text = _labelValue;

  labelSet = false;

  }

  }

  }

  }

  Pretty basic it creates a tag in the Panel.  Opinion, he still has the labelValue public property which, when set, sets the text in the label.

  Now for the main application

  <>

  "xmlns:MX ="http://www.adobe.com/2006/mxml"

  Layout = "vertical" width = "100%" height = "100%".

  creationComplete = "createPanels ()" > "

  Used to store references to the panels when you create

  private var panelReferences:Array;

  My replacement for xml, but will work the same way.

  private var myData:Array = new Array)

  {panelName: "Group 1"},

  {panelName: "group 2"},

  ({panelName: "Group 3"});

  Look in the table (your XML and create panels

  private function createPanels (): void {}

  panelReferences = new Array();

  Create panesl and add on demand

  for (var i: int = 0; i

  var mPanel:MyPanel = new MyPanel();

  mPanel.labelValue = myData [i] .panelName;

  mPanel.width = 100;

  mPanel.height = 70;

  Add the panels also in the table of references

  panelReferences.push (mPanel);

  addChild (mPanel);

  }

  }

  private function changePanelHandler (): void {}

  Change the label of panels in the panelReferences table.

  Target group by using the index number

  panelReferences [ns.value] .labelValue = newLabel.text;

  }

  ]]>

  It loops through the data in the table that is the source for the panels.  As he does and creates a new Panel, it adds to the application, but also the reference to the panelReferences table.  Now in the demo app every time you want to set the value, you just do it on the reference in the references table and so it's a pointer property labelValue Panel Gets the value, and then updates the text in the Panel.

  I think that this covers what you want.

  With regard to the interfaces.  Tell everyone your signs accepts different types of data (they are all channels) and implemented the data in different ways.  Her you would use one interface.  This would ensure all panels used consistantly Sami methods, but might implement these different ways.

  I hope this helps

• How to create a Global Variable through the Project Explorer

  Hello world!

  I know how to create a global variable (in a vi through the range of functions...).

  but I'm missing a way to create one via the Project Explorer.

  It's a missing feature or just this documentation (and the intuition of myself) are missing?

  It would be very convenient.

  THX for your time and hope that answers.

  jwscs

  Right click on my computer > new > new... > select Global Variable.

  EDIT: although I agree with Gerd (he probably wondering why you need so we can recommend a better way ), I rarely use them in easy to write once - read many applications such as security levels overall program at initialization (VER) to read later, but NOT modified.  I know it would be better to make a good class, functional Global Variable (FGV) or a motor Action (AE) but globals ARE practical and safe IF used wisely.

• How to create a shared library of Qt and use it on App without a head?

  Hi all

  I'm experimenting with some waterfalls headless basic application development, and I just hit another problem of blocking.

  I want to create a Qt library with some shared code between the head and user interface elements.

  That's what I did:

  1. created a new application without head the wizard project
  2. created a new library shared by using the wizard project. Adds a simple C++ (Qt not) class
  3. Set up the two parts of the Headless App to use the shared library ("Library in the workspace project" option from the "Add library...) (' Assistant).   Everything compiles and works very well so far.
  4. Now, I want to use the shared library Qt. I choose 'Library of the Standard BlackBerry platform' and ' platform > Qt Core "from the «add library...» "Wizard. Now, I had this error on the shared library project: C:\dev\bbndk\host_10_2_0_15\win32\x86\usr\bin\ntoarm-ld: could not find lQtCore.

  How to create a shared library of Qt and use it on App without a head?

  In fact, I would also use other NDK libraries on library shared as lbbdata and libbbdevice.

  I expect that workers would deal with all the problems for me. As an improvement, I suggest you add the selection screen platform library of the Wizard "Add library...". «the wizard «Shared Library Project»

  There is a model of library project

  https://github.com/BlackBerry/Cascades-community-samples/tree/master/Cascades-library-template

  Unfortunately, the library create Assistant isn't really useful #t

  There is also a great series on using headless headless library and user interface:

• How to create a button icon / browse files

  Hi all, I have 2 questions I want to ask you:

  1. how to create a button icon using action script?

  I add this part of the code at the top of my file .as just below the keyword package:

  [Bindable]
  [Embed(source="/images/pause.png")]
  private var pauseIcon: Class;

  I then added, in the main function, copy the following code:
  var pauseButton:Button = new Button();

  The compiler problem with the "private var pauseIcon: Class; ' line and the new line of declaration of button.  I declare the type of button?

  2. how to browse files in the Simulator? I try to use browseForOpen, but it does not work.  It shows a blank dialog box saying no file meets my criteria.

  var docFilter:FileFilter = new FileFilter ("Files", "*.") *") ;

  var myFile = File.applicationStorageDirectory;

  myFile.browseForOpen ("Open", [docFilter]);

  The embedded definition must be within the class as a normal attribute / member of this class.  You have outside the classroom.

• How to create a button "call" in sensitive site DW bootstrap?

  How to create a 'call now' (telephone) button in sensitive site DW bootstrap? I had such a button with jQuery a few years ago, but it doesn't seem to be compatible with the JS in a current model of DW. Thanks in advance.

  Ron Finley

  Use the such with phone number attribute.

  tel:12345678">Phone: 1-234-5678

  If you want a "bootstrap" button, add button classes.

  tel:12345678">Phone: 1-234-5678

  If the web device of the user does not have a phone app, it won't make any difference.

• Looking for tutorials on how to create invitations on Adobe Illustrator. [was: help!]

  I atually I was wondering if anyone knows the best resource to learn how to create invitations on Adobe Illistrator. I looked for all the open classes at my local college even went up to contact a total stranger of facebook that has been a graphic designer of facebook who has not had the time to teach me how to use this program. There must be something you can do to learn these programs hands without going to college to learn how to use them. I surfed on the internet for videos, but none that go into the detail I'm looking for. Any suggestions, classes or local designers who are willing to pay for their time?

• How to create multiple CSS navigation bars?

  Hello

  How to create multiple CSS navigation bars?

  I currently have the code below (and it works very well) for a navigation bar, but I'm trying to create navigation bars .  Can I just change the 'nav ul li a""NAV ul li b"(note the 'a' change to a 'b') or something similar?  I can not understand the correct coding...

  Thanks in advance for any help!  I very much appreciate quick and precise Adobe support team answers!

  NAV ul {}

  No, the 'a' you see is an html element, , you can not change this.

  It's very simple.

  You can create a class, the name you want (I used .yourclass), add it to the second
