Another Question for C++ question QML class

Similar Questions

• 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.

• Yes, another question regarding the freezing of Safari - EtreCheck report included

  Yes, another question regarding the freezing of Safari.

  From a little over a month (I think), Safari started freezing regularly whenever I want to open new tabs or switch between tabs. I found myself to leave the program several times per day / hour. I can't identify any specific common cause (other than my MacBook being old) or any new software or updates that might have initiated the question. At first I thought he might have many tabs, I tried to open, but recently it happens even with only a few tabs open.

  I worked through the steps I found in this forum and others: empty the cache, start in safe mode, etc nothing works.

  Based on the previous suggestions, I have downloaded and run EntreReport which I included below. The note and maybe just a distraction, but EntreReport has crashed three times tonight, before he was able to produce the sub report. I ran the report after restarting my system with no other programs running.

  Suggestions are welcome at this stage because I want to start using Chrome or Firefox because I like the transfer procedure between my devices.

  Thank you in advance.

• Another Question... Pasted the first album... but does not work properly

  Hello-

  Another question - I stuck my first file (wpa without loss) from the album on my rocket and when I go to him, he travels only (so 1,2,3, etc. and then it again.)  The songs look like they have any length, if that makes sense.  The bottom bar is from 0:00 0:00.  The strange thing is the player will play all music pre-loaded there, and when I tried to copy a song the player on the computer off, he played.  It is therefore not the file of the song itself I guess.

  What I've done wrong? And how to fix it?

  Thank you very much!!  This forum is very useful for a beginner!

  WMA Lossless is not a supported audio format. Which means that it won't work. You will need to re-Ripper in plain ' ol .wma, .mp3, .ogg or .flac format.

  Hi ya'll! I'm still learning how to navigate my way with Lightroom. (Last time I wrote, I got a few responses that work.) Thank!) Now, I have another question. When I try to copy photos to my external hard drive to a CD/DVD, no matter if do leave LR or my car, I get the message; "Disc burning is not supported by LR on this computer." I've tried everything I can think of, so, I thought I'd see if anyone can find out if there is something I can do. Or could it be that my computer just can't handle it? Help! So frustrating!  I have a Lenovo PC, I don't know if that makes a difference. Any ideas? Thanks a lot for your help!

  You burned discs with other programs using this computer? Are you sure that you have a drive that will burn the disks?

• Another question about Dates

  Hi, I have another question regarding the use of the field date in Adobe Designer 8.  I have the updated domain in place so that the person can enter the date, lets say, 12/12/11 and it will convert to December 12, 2011, or, the user can click on the calendar that is attached to the date field and make a date selection.  My question is this.  Is there a way that can not only the calendar go to any date by selecting < or >, but can also go to an exercise < < or > >?  We have contracts that extend from 2 to 3 years and want this option to be available.

  Thanks for any help you can provide.

  Here is how I currently have my date fields in place.

  In the field section:

  View model: MMMM D, YYYY

  Edit pattern: M-D-AA

  Section of the value:

  MMMM D, YYYY

  Date must be entered as per example, 12 January 2012

  Liaison section:

  MMMM D, YYYY

  The calendar widget allows you to select other years.

  When you open the calendar, click on the name of the month, the calendar will show you every month of the current year.

  When you then click on the year, it shows you all the years of the current decade.

  

• Another question of novice!

  Hi guys...

  I had this posted in another question I raised yesterday... so thought that I should probably get a question by discussion

  A year after double view and month appear on the structure folders after you import the photo

  See things like

  Folder Image count

  10 2009

  2009 480 p

  If I import files with the correct creation date year etc... Why LR would create two folders with the same name...

  See you soon

  Steve

  Hi I think I've sorted it... Folder locations are the same as in

  C:\Documents and settings\stemcg\my Documents\My pictures\

  I looked at the link at the top... when I right click on the files and selecetd add a parent folder that it changed the view of annual records being next to each other for example...

  5 2010

  2010 5000

  4 2011

  2011 4096

  It separated like this

  upper part

  1996

  2000

  ....

  2009

  2010 5000

  2011 4096

  My Documents

  My photos

  2009

  ......

  5 2010

  4 2011

  I then right click on the folder with the least number of photos in there for example

  My perso\Mon pictures\2010 I selected update folder location.

  I pointed out the Selection tool in the same folder that is my perso\Mon pictures\2010. Then, he gave me a prompt to merge the files... It merged then deleted the My Pictures folder and added photos in the folder above... it looks like now

  upper part

  1996

  2000

  ....

  2009

  2010 5005

  2011 4100

  My Documents

  My photos

  2009

  ......

  The folders listed under my photos with the count in the records of the year preceding has increased in quantity... IE 2010 went from 5 000 to 5 005 photos...

  result!

  Thanks for the pointers guys...

  (one day I'll have the shot of LR!)

• How remove the toolbar Babylon. Is there another name for "Babylon"? because I don't see a "Babylon" in my control panel, of it being installed? Help

  I would like to get yahoo as my home page. I tried to change, according to the instructions of mozilla. It did not work.

• To add another disk for HP a6430f desktop

  Product: Office KJ378AA-a6430f

  OS: Vista, which is updated automatically

  I want to add a HDD that is identical to one already installed in the system. This player is WDC WD64 00AAKKS-65A7B SCSI. I looked inside of the Cabinet Office and there is room to install it in the drive cage, but it's not obvious where to plug them. This isn't an IDE connection where you can connect two drives on the same cable. I see 4 SATA connectors. Which should I use? Should what cable I use?

  Another question:

  Is there a problem hang a SCSI disk to a SATA connection?  Does not have to be as original drive is a SCSI! Are they the same? Please explain.

  I want to clone the first drive on the other. Is there an easy way to do this and then using the second drive as boot drive?

  I have just enough knowledge to be dangerous in all of this.

  Thanks in advance for the help,

  Charles_Harward

  Hello

  I tried and it worked, but in the process, the wiz disc program cause a problem with acronis true image 11 which has been installed on my system. When I removed the disc wiz he screwed the software acronis and I had to remove that too. The installation not found for the real picture discs acronis therefore finished by buying the latest version of the software. After I bought the software, I found I could not recover the worm 11 from the web. (I didn't know that acronis program I had would have cloned the disk in the first place.) Anyway, everything is changed on the new disk.

• Why when I open my email on another computer for example, in Outlook Express or the site of Telstra all my e-mail messages get deleted from the full mail?

  When I opened my email on another computer for example, in Outlook Express or on the Telstra site do all my emails in my inbox deleted completely from complete Mail. This happens with two email addresses different set up on two different computers. I wish that my e-mail messages to stay in complete Mail unless it is deleted from there. Thank you

  Your question is not clear. Is this something that happens, or something you're worried might happen?

  Whatever it is, the answer depends on what you do and how your email clients are set up.

  If you use POP in Outlook Express (really? "It's a very old program!) so he can delete messages from the server. You should be able to leave messages on the server, or you can switch using IMAP.

  Just looking for messages in your Web browser will not erase all messages, but if you delete a message there, again whether or not it is also deleted on any of your computers depends on whether these computers using POP or IMAP.

  I am aware that I have you confused probably further.

  My preference, as I want to be able to work with my email on multiple devices different, is that you use IMAP only, but others can, for various reasons, choose to use pop. There is no good or evil, what suits you best, but in both cases, we must understand a little the operation of the service.

• Use a custom in a signal qml class

  I want to use a custom in a signal qml class, but have difficulties of implementation that correctly.

  My class is OutgoingInputs

  I give the floor

  qRegisterMetaType("OutgoingInputs");
  

  Save a pointer to it as a type of meta, which seems to be necessary, but when I also use

  Q_DECLARE_METATYPE(OutgoingInputs*)
  

  in the header file for the class, I get a compilation error.

  I have to save it without a pointer (was the idea here ) or is there another obvious error?

  Is there an example how to do this?

  I can receive the signal if my housing uses no parameters.

  I don't think you need to register as a metatype... a simple registry should do as it is the same as the use of the QML object:

• Drop-down field - when some entries are selected are unavailable another field for data entry

  Hi all

  A sorry again, I am very new to forms and have another question. I have a drop down list which list by selecting certain values I need an another field will not be available if the user can enter data.

  Hopefully this example is logical:

  Drop-down list	Champ %
  Outdoor	Not allowed to enter data
  Previous	Not allowed to enter data
  Interior	Not allowed to enter data
  Cotton	Allowed to enter data
  Wool	Allowed to enter data

  If someone could give me some examples that would be a great help.

  Thank you very much

  Here is a script that you can use for the validation script custom from the drop-down list. It resets the value of the text box, whenever a change is made to the drop-down list. You can get rid of the line doing it, if you do not want to. Change "text1" in the code to match the name of a text field that you are using.

  Validate a custom for picklist script

  (function () {}

  Get the selected value

  v var = event.value;

  Set up an object to associate status items text box read-only

  var f_state = {}

  'Outside': true,

  'Back': true,

  'Interiors': true,

  'Cotton': false,

  'Wool': false

  };

  Get a reference to the text field

  var f = getField ("text1");

  Clear the text field

  f.Value = "";

  Set the State of read-only text box based on what is selected

  If (v f_state) {}

  f.ReadOnly = f_state [v];

  }

  })();

  You can check the setting of the home page and make sure that it doesn't have a leak ' |'.

  Firefox supports several home pages separated by ' |' symbol.
