• Using C++ in QML classes: need for Clarification

  I have read the document using classes in QML C++ and understood that we must call qmlRegisterType before using C++ in QML classes.

  But I found that some (or all?) of the classes can be used in QML without call qmlRegisterType in advance.

  Example of

  import bb.device 1.0
  
  Page {
    attachedObjects: [VibrationController {id: qmlvib}]
    Container{
         Button {
                      text: "Test vibrate"
                      horizontalAlignment: HorizontalAlignment.Center
                      onClicked: qmlvib.start(100,100)
                     }
      }
  }
  

  I also found the SensorDemo project using many classes of QML sensor final qmlRegisterType<>(). But it does not call qmlRegisterType<>for VibrationController (?).

  I wish I had a few questions:

  1. How will I know which classes can be used in QML without qmlRegisterType<>()? Is there a list or the rule to help me know?

  2. what should I look at to decide using C++ class in QML directly (without qmlRegisterType<>(()) or with qmlRegisterType<>(): as the performance, memory management,...?

  3. If you can choose to use the C++ in QML class directly (without qmlRegisterType<>(()), BB shoud put it in the paper?

  Sorry for the many questions. I'm just a beginner on BB.

  Thank you very much!

  (1) I think that some classes are pre-registered. If it works without adding it yourself: looks like it was a.
  (2) I don't think that there is a performance issue with the help of registerType
  (3) No, there is not, just of the classes that are recorded automatically by the system.

• using a custom field - noob

  Hello

  I'm quite new to Java programming, I followed some of the guides provided on how to create Blackberry applications, though.  However I followed a pdf document called development, which describes how to create custom controls/fields.  The problem I have is once the class has been created, how to use it?

  I created a class called customButtonField.java, I try to call to create a new field as follows,

  customButtonField customButton = new customButtonField ("click me", "SQUARE", 0);

  The error I get is,

  cannot find symbol

  symbol: method customButtonField (java.lang.String, java.lang.String, int)
  Location: class mainScreenStyleScreen
  customButtonField customButton = new customButtonField ("click me", "SQUARE", 0);
  ^

  It is what is in the customButtonField class

  public customButtonField (label As String, int form, long style) {}
  Super (style);
  _label = label;
  shape _shape =;
  _font = getFont();
  _labelHeight = _font.getHeight ();
  _labelWidth = _font.getAdvance ("_label");
  }

  Any help would be appreciated!

  Hi mabs.

  A problem that I found with your code is that the average parameter set in the CustomButtonField constructor is 'int form'. However, when you call create your new instance with the "new" statement, you pass the value "SQUARE". 'SQUARE' is a string. If you pass a string as a parameter that requires an int.

• applicationContext remains "null" after using the custom url scheme to launch the app

  Hello

  I am currently working on a DPS application for a customer who wishes to use its own authentication system.

  The client system is implemented so that they send the valid token to a URI with a custom method.

  By setting the same pattern custom in my app DPS constructor, I can get the app from the login window.

  What is described in the library of DPS & Api store 2.32 documentation, I understand that

  " adobeDPS.configurationService.applicationContext must contain several variables associated to how the viewer was started or enabled:" ","this class represents the context under which the application is launched '

  
  

  However, in my application when I try to see what contains the applicationContext, the object is always 'null '. It doesn't matter if I started the application by clicking on its icon or if it was launched using the custom uri scheme.

  
  

  Is this a bug or am I missing something here? I really need this token.
  

  Hello

  After being stuck for a while trying to work with the url of my client for usage, I finally tested it with a modified version and have found the cause of the problem.

  Work of first information provided by a colleague who was apparently not detailed enough for the customer asked me to use a url of the form App. scheme://auth/#token=...

  It turns out that this kind of url can start or bring the app to the front, but applicationContext remains empty.

  My tests using a url in the same form as you suggested (eg. app. scheme://v1/slot/library) can trigger the app or transmit data.

  The documentation available in the SDK library & shop and article on how to use a custom template is very vague on what formats link actually works, and how we can vary with it.

  A breakdown of official links to pieces, that the parties do and what items can be modified (for example ' / appstate') within the API documentation would be a great help for developers, I think.

  Kind regards

• One of your filters uses a custom header that contains an invalid character.

  When I send an email, you receive the following error message:

  «One of your filters uses a custom header that contains an invalid character, such as ':', a nonprintable character, a non-ascii character or an 8-bit ascii character.» Please change the msgFilterRules.dat file, which contains your filters to remove characters not valid in your custom headers".

  It is followed by a message saying that the email was sent and saved despite the error.

  The problem occurred after the transfer to 10 Windows (from Win 7)

  I deleted all files msgFilterRules.dat and all filters, but the message persists.

  Any suggestions on what else to try?

  Thank you

  Problem solved.

  After you delete all files/imap mail entries, the problem disappeared.

• How can I clear the browser history when you use the custom settings for history?

  When my history option is set to "Use the custom settings for history", the options page has no link to "clear recent history". There was formerly a menu option, but that seems to be gone now with Firefox 29. Is my only option to access the dialog box, clear the history all to change the historical option to history to remember and then change it back? Is there another way to access the option erase history all?

  I think you can get the menu bar by pressing the ALT key. If you want to return permanently, click View > toolbars and check menu bar.

• Firefox guard handed himself to "never remember history" even if I say "use the custom settings for history".

  Firefox seemed to work fine until yesterday. When I used Firefox yesterday, my home page was changed to Firefox start page and did not open my tabs from the day before. I went to settings and changed the homepage back to google.com and told to "use the custom settings for history". I closed Firefox and opened it again and my homepage was google.com, as I put it, but it was back to "never remember history". I tried several times, yesterday and today, but Firefox keeps affecting himself never "remember history".

  Choose the 'use the settings customized for history' parameter is not make changes to the parameters of the history and cookies.
  
  Firefox displays the "use the custom settings for history" as an indication that at least one story and cookie settings is not the default to make you aware that the changes have been made.
  
  If all the history settings are default, custom settings are hidden and see you "conservation rules: (never) don't forget history."

  Don't remember history"means that private browsing is active and"Always use private browsing mode"Gets a check mark.

• my privacy setting is stuck on do not forget history, won't stay on using the custom settings for history, after I've selected and click ok

  When I go to tools, Options, privacy and "Use the custom settings for history" of the value and then click on OK it won't save. It remains on "Remember history", even if she never will save "remember history" as I tested it. It seems if be produced after these recent last Firefox update. Anyone know why I can not choose "Use the custom settings for history", as is the parameter I want to use?

  Why aren't satisfied with the history settings by default that you currently have?

  Any changes (for example, to disable the cookies third party or form not given memory or keep cookies until you close Firefox and make an exception for the cookies you want to keep) that you will cause "use... custom parameters. "to be selected if you really want to see.

• Use of custom in Veristand files

  Hi all

  Have not been able to find a lot of documentation related to the use of "Personal files" in Veristand.  I would like to know some examples of the types of files users have set up.  Specifically, I would like to know if you can "call" some types of models or devices personalized (i.e. for databases or configuration settings).

  Thank you very much

  Hi GSinMN,

  It has custom there some documentation in the help of VeriStand, which deals specifically with files.

  Adding custom files

  http://zone.NI.com/reference/en-XX/help/372846D-01/VeriStand/add_custom_files/

  Although aid is not quite fully reveal the capabilities of this feature. There are two distinct use cases that I could identify for the custom in VeriStand files option. I'm going to the list of people the more detail and show you an example.

  Make easily accessible to the driver files in the development environment.

  When a file is added in the custom files in the project section, it will have its own icon in the project and is included in the project dependencies. Having the file to display in the project is useful if there is a picture of troubleshooting or a specific document (calibration sheet, how to run a test, etc.) that you would like as your operator to have access to. For example, in the sample project, I realized, there is an added file called "TestA1_PreTestSetup.txt". Of the project (on the toolbar), the operator has the option "Open a file" (to view) or "export...". "to investigate his path on the computer of the operator.

  

  Please note that the file is now added to the dependencies of the project.

  If you start to investigate the project file and lets say you do a right click on it and notice that there is a Properties option. You may notice that the Description of this file is empty. In fact, it can be filled by modifying the XML source of the .nivsproj. It also leads in the second case of the use of custom files.

  Transferring files to the aim of RT which can be used by the VeriStand engine.

  If you were to investigate the .nivsproj XML, you could first find the section of the custom files, then the tags of the element that you configured.

  

  Here are the relevant tags and a jump down,

  -It points to the source of the custom file. In this case, I added the file in the directory "C:\Users\Public\Documents\National Instruments\NI VeriStand 2011\Test procédures". He is able to solve the first component 'In common Doc Dir' because it's the common directory for VeriStand, and he added then the folder of the test procedures and the name of the file that I created.

  -Fill this tag gives us the opportunity to complete the description information that occurs when we right click on the file in the project.

  -Fill this tag gives you the ability to also send the file to the target deployment. Your VeriStand engine can then access this file during the operation. With respect to the types of files that you want to use, the link in the post above should help guide only.

  Please Note: change the XML of the project offers more customization and functionality of your project, but these changes should not be made whole. An incorrect change tags in the XML file can lead to results and poor execution. Then move forward with caution and only make minor changes at the same time.

  I hope this helps. Have a nice day, GSinMN

• [ACCIDENT] Crash when using ' equal to ' function of the String class

  When I use "equal to" function of the String class to compare 2 channels, the app will crash.

  Examples: pn_infopush.equals (PN_INFO_TIMER)

  I have to use "is" instead of "equal". The application will run normarly

  Does anyone have any idea who? I don't understand why.

  Thanks for your support!

  Hello

  Is there a chance that your variable can get a null value?

  Calling .equals not a null object can cause this.

  What type of exception you get? Can you provide a stacktrace?

  When I try to send a page using the normal text field, he's fine. But when I use my custom plugin it throws error PPV.

  You can see the plugin code in the shared components of the application.

  Application is called theme MDL.

  
  

  There also may be problems with my page template but I doubt since the ordinary questions works very well.

  
  

  I developed this on 4.2.6.
  

  Incredible.
  The problem is that the plugin was wrapped with

  As soon as I took it, it could submit its value.
  It's funny how I had no idea how fix it, but as soon as I saw you talking about form I knew what to look for.

  It would be cool to know why this happens.

• Use a custom in a map icon

  I created a custom font, which consists of 15 simple icons. Each icon is mapped to a unique position. For example, type "A" produced the first icon, typing a 'B' produced the second icon, etc. The police is an OpenType font, and it works fine in all my office applications. I would like to use this font on a map.

  I downloaded the files of OTF provided this font custom that another police OTF (km) text content & Layouts > fonts.

  I have a card that contains 2 fields of text box: Description and title. Description use my custom font, and the title used by the police of km.

  In collections that are mapped to this card, I have an 'A', 'B' or 'C' in the Description field, and my title of the current collection in the field. So I expect that there would be an icon appears on the first line of the card, followed by the title of the collection displayed in km on the second line.

  But the police of the icon does not display the icon. It shows only a capital A, B or C. The title of the map by using the font of km appears correctly.

  Isn't this possible? I'd wait the police icon to work properly, since the system has no way of knowing that the 'A' looks different than a usual A, B looks different from a and B, etc.

  Also, I tried this visualization as my Preflight custom app that my application development custom iOS and Android.

  I got this to work, but 2 things I learned, in case anyone has the same problem:

  1. the police I used was a police custom that I created that had only a single character (a capital ' A') that I created for the test. Until I filled the police with the characters A to Z and a to z, the police gave a strange error message when you try to use the font in a card.

  2 as Nathan said, you must rebuild the application after adding a font. I had forgotten that.

  FWIW, I used the excellent "Indyfont" script for InDesign to quickly create an OpenType font containing the 15 special icon characters we need. Has no time at all to create the font. See Indiscripts: already

• How do we use a custom in AvailableRefinements view?

  HELO,

  We want to use a custom view (subset of the Base) in the component AvailableRefinements (Guided Navigation) but only the Base view appears for the selection even though other published views exist in the application.

  It is even possible to use a custom for this component view? If not, then what is the best way to achieve this?

  We have different types of data all combined into a single dataset. It may be that a single application with multiple screens and each screen should show a specific data type. There are also some common attributes. These attributes shared by guided Navigation should show only values that belong to the data type of screen. The custom view would help if guided Nav accepts one.

  Thank you

  VJ

  You can also load several Collections/sets of data in your data field.
