  in one of my translation of applications inside QML using qsTr ("my text") works only in main.qml.

  all the other qsTr (...) is ignored.

  Hello

  I am creating a list as an example of stamp,

  for example: I break the code of stampcollectorapp qml,.

  I think that you must import them into the upper part of your qml, cites the example of application a qml files in subfolders

  See here:

  https://github.com/BlackBerry/Cascades-samples/BLOB/master/quotes/assets/main.QML

  EditScreen is imported in main.qml, and EditScreen is in assets/EditScreen/EditScreen.qml

  I don't know if the name of the folder is the same as the qml file name is a convention, then I would try to mess around and see what works.

• How to use cppObject in several QML files?

  I have a variable cppObject of context set as usual:

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

  QML-> setContextProperty ("cppObject", this);

  And it works very well in the main.qml.

  Problem is that it doesn't work in the second pagetwo.qml of QML files that is created on the fly in main.qml when the button is clicked.

  No idea how access C++ pagetwo.qml?

• Several QML files

  Hello

  I'm a developer of Java, Blackberry, and I am trying to learn C++ and QML things, so I have no idea if this is stupid or not.

  I have the assets/qml file, which I configured on my .pro file:

  {lupdate_inclusion}
  SOURCES +=... / Assets/QML / *. QML
  }

  Now I have discovered that I can create custom components, to integrate it on some pages.

  What I want to do now and I tried withou success is:

  How can I use two separate files QML?

  / Assets/QML/pages / *. QML

  / Assets/QML/Components / *. QML

  You can use them just like that, at least, I do not change my project folder.
  qml, you use import "folder_name."
  for example:
  import "preferences."

  I get in homepage.cpp root is not declared in this scope. I want to click on the main.qml button, I go to new file c ++ and call homepage.qml

  Hello
  I highly recommend investing a few weeks in learning C++ before learning the stunts. Specifically, these topics:
  -Advance declaring types
  -Memory management
  -Classes & inheritance (different from Java, a lot)
  -Life management object qt (parent/child, order of destruction of object relationship)

  These are essential, but we can't really help with them in the form of forum.

  On the compile error, this should probably fix:

  Homepage * home = new HomePage (NULL);

  But there are other problems in the statement of homepage. It's the manufacturer probably shouldn't take an instance of class ApplicationUI as the parameter.

  Hi Wally, the hard disk OS X and all of your files. Get a case for your reader, and it backs up. Try OWC

  Always keep your Mac backed up on an external drive with Time Machine or utility of cloning like SuperDuperor double clone.

  Try eBay for the adapter.

• How can I connect Windows XP to several networks, Wi - Fi for internet and the other for file sharing?

  On windows XP, I need to connect to two different networks. Free wifi for the internet and the other for file sharing.

  Different gateways, different static address, same subnet mask. But there is problem when operating simultaneously and must

  a network must be disabled. Is it possible to run simultaneously?

  original title: served various networks simultaneously on windows xp

  Go to where you have configured the static IP addresses for your network adapters.  Leave the "default gateway" blank for your local file sharing adapter and insert a valid default gateway for your wifi Internet adapter.  Of course, this will limit your adapter in a single subnet - which should be OK for use at home or small office to share local files.

  This should work as long as the two physical subnets have two different subnet numbers. In general, this means that the first three digits of the IP address of the adapter can not be the same on both adapters - if they are, then you need to make one of the subnets. (i.e. one is 192.168.1.xxx and the other would be 192.168.2.xxx).  This is usually accomplished in the router configuration page.

• The Devs creating their active Frame for a separate QML file covers? I'm stuck

  Bit in trouble, I do my best to bring my Apps support 10.2.1 10.2.2 I practically everything by working the * beep * covers Active, I did do a check and create the file QML according to less than 10.3 or greater

   ComponentDefinition {
              id: creator;
              source: ""
              function createQMLObject(sourceUrl){source=sourceUrl; creator.createObject()}
          }
  

  Feel free to use that btw ^.

  if(olderFirmware===true)  Application.setCover(creator.createQMLObject("CoverOlderFirmware.qml"))
          else{Application.setCover(creator.createQMLObject("Cover.qml"))}
  

  Now for some reason, they do not work, they seem to be created, but do not want to show, normally I would create it from my main.qml but the passport and its lid Multi forced me to separate the covers in their own QML files

  Begins like (not included UI code)

  import bb.cascades 1.2
  
      SceneCover {
          id: large
  
          content: Container {
              background: Color.create("#000000")
              layout: DockLayout {}
  }
  }
  

  Place in a container gives me a weird error on not able to create a list in an object, probably referring to MultiCover and SceneCover as a child of the container.

  Any suggestions?

• Waterfalls of Beta 4 - cannot change the QML file

  Anyone else unable to edit QML files with the new Cascades Beta 4?

  I can edit in text mode, but the default editor is suspended the IDE when an existing QML file is changed.

  Have you tried a new clean rather than installing on Beta 3 installation?

• Load a sheet from a QML file

  Hi, now I have a sheet of attachedObjects and I open it with mySheet.open ();

  I want to move it to an external QML file to make my code more readable, but it does not work. What should I do?

  Hello

  If you have something like this:

  hand. QML

  attachedObjects: [
          Sheet {
              id: loginSheet
              content: ...
          },
  

  Just move it to an another qml:

  MySheet.qml

  Sheet {
    content: ...
  

  hand. QML:

  attachedObjects: [
          MySheet {
              id: loginSheet
          },
  

• Animated images in place when loading new QML file

  I noticed that when I insert new QML files, the images Animate into place.

  For example, if the screen contains an image at the position X, Y, and width W and height H, then the image becomes visible at the point of coordinates 0,0-0 width and height 0 and anime then in place by flying over to the X, Y coordinates and more in addition to being finally width W and height H.

  If I then click on the 'Back' button and enter this QML screen a second time, it does not animate.

  This implicit animation is intended?  While the implicit animations are pretty amazing and a great tool to have, it seems intuitive to the use of screens animations implicit when they are first loaded. It creates a rather unpleasant company and Visual distraction when loading screen.

  I thought that I could disable it by adding the following to the ImageView controls:

                  attachedObjects: [
                      ImplicitAnimationController {
                          enabled: false
                      }
                  ]
  

  ... but they are always animate.

  Thank you

• To access the properties of QML context through several QML files

  It seems so basic, but I don't see how well...

  I put a 'WebAPI' context property to access my class that makes HTTP requests etc. WebAPI works very well main.qml, but when I try and use it in the included LargeThumbItem.qml I get:

  "LargeThumbItem.qml:37: ReferenceError: can't find variable: WebAPI.

  How to set a context property that is available for * all * my QML files? What is the best practice for this?

  hand. QML

  {

  ...

  {ListItemComponent}

  type: 'point '.

  LargeThumbItem {

  }

  }

  ....

  }

  LargeThumbItem.qml

  {

  ....

  WebAPI.getImagePath (...)

  ...

  }

  I do the usual configuration...

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

  QML-> setContextProperty ("WebAPI", m_pWebAPI);

  I tried calling qml-> documentContext()-> setContextProperty(), but it did not work. Is there a global context that I can put all documents will inherit? (the API documentation seems to suggest there is).

  This problem is related to what is described here and the solution is the same. The problem is that the ListItemComponents have a different context and lifecylce due to the fact that they are cached in and out as the scrolls of the ListView (see here for details).

  I solved it by adding a dynamic property on the global object of 'Qt' for example in onCreationCompleted() or anywhere where the senses in main.qml. In my case, I chose to pass a string, because I don't know if the global property to the instance around WebAPI is a good idea.

  Qt.homeListBaseURL = WebAPI.getImagePath ("TitleImagePathPrefix", "170 x 240")

  Then in LargeThumbItem.qml for example

  {WebImageView}

  ...

  URL: Qt.homeListBaseURL + ListItemData.ContentId + '.jpg '.

  ...

  }
