What is the ': QObject (app) "in examples

I was writing my app without it, but a few samples and examples use.

Since I'm not a C/QML developer, I don't know if it's something from one of them, or it's something waterfall, someone has a logical explanation for this?  It does really? Is there any use for this piece of code?

Example: https://developer.blackberry.com/cascades/documentation/dev/integrating_cpp_qml/index.html

a property of the class is initialized with a parameter, it is called initialization list.
See
http://www.parashift.com/c++-FAQ/init-lists.html

in this case the TestApp is a QObject and its parent is set to the app object. You can learn more about this feature here:

    I have a MacBook Air (2015) and I was wondering what my options are, as far as security.  I want something that will take a photo using the iSight camera if a wrong password is entered in trying to connect to my MacBook and will send an alert on my phone?  I've seen a lot of options with Android phones, some have even alerts that give you a GPS telling you where your device, if stolen, would be, but I don't have an android phone...  So does anyone have any suggestions on software like this, or any other type of security software?

  • What is the difference this 2 examples of photos? Use function IMAQ detect circles to detect the GREEN button.

    Hi all

    Please refer to the attached 2 pictures, they are similar, just the size is defferent. (pass PNG, 5478 pass. PNG).

    But now I try to use IMAQ detect circles to catch the GREEN button. For the PNG pass, it works very well, but for another example, it is still does not detect this button.

    I also try to change the curve settings and note that entry, but still no. Another way, I also try to use function IMAQ find circles , but the result is worse that IMAQ detect circles, so give up.

    The code is detect the circles.png, copy of block diagram.

    So what is the root cause? Thanks for help.

    Hi colinzhang,

    The extraction of curve so it uniform mode, you can get the result.

    -Suggestion, if you want to use the entire image area as KING should get the size of the image, get the rectangle and convert it to the descriptor of KING. (I think this is unnecessary)

    -Be careful with the extraction of the plane, u use default color which is the Red plan. In this example, it is fine. but make sure you know what aircraft you are extracting.

  • What is the installer.app?

    Nobody knows what's 'installer.app '?  It looks like a pig... major on my monitor of activity... I'm trying to diagnose performance problems do I need?

    Hey there Celeste Jones.

    After researching this a little app, looks like it may be an old app that is not supported. I suggest looking up the app in your Applications folder and get rid of it, because it is probably more useful for you.

    Thank you and let us know if you have any other questions.

    See you soon.

  • For the iPad 2 air, what is the best app for note taking allows you to use a removable keyboard and a stylus? Which is also a stylus good to use?

    I am looking to buy an iPad 2 air to take notes in college classes and I was wondering what is a good software that allows an external keyboard (like a laptop) to type notes and also allows the drawing with a stylus? What is a good pen that is compatible with the app and the iPad 2 air?

    If you really want to use stylus to take notes or draw you should go for iPad Pro with Apple pencil. Nothing else offers good experience especially for hand writing. If you ok with drawing then only pencil FiftyThree is a good choice on iPad 2 Air (but again, it is much worse in my opinion, then iPad Pro + Apple pencil). FiftyThree is also one of the best (paper) apps for note taking (and it works well with their pencil).

    The keyboards are wide work system and not a dependent application. You can go for any model of the 3rd party like you which is compatible with iPad air 2. Advice covers the Apple Smart keyboard are specific to the Pro (they need specific for Pro iPad connector).

    There are two choices, Paragon and Tuxera.  Both received mixed reviews.

  • What is the advertising App Store (IDFA) identifier?

    Hello

    I m download an app to itunesconnect and I m using the extension milkman games native to Admob and I m for the first time ask if my application uses the identifier of advertising (IDFA). Can anyone tell me if it does, and how should I answer these questions?

    This application uses the identifier of advertising to (check all that apply):

    Serve the advertisements within the app

    Assign this app installation to a served advertisement

    Assign an action taken within this app for a served advertisement

    Thank you

    Hi Paul,.

    The last DONKEY milk you will need to check the box "serve as ads" and one named "Announces follow-up limit", but not the other...

    The other "questions of the attribute" according to me, is only necessary when you use the Analytics tools, donkeys etc.

  • What is the best Netflix app for my iMac

    Hi all, new owner of the iMac.  I was wondering what's the best app for Netflix, I downloaded a streaming and I had to download Silverlight but overtime, I try to watch Netflix, download Silverlight notification arrives.  I'm doing something wrong?  Little different from my iPad!

    There is no Netflix App for OS X.

    You need to access Pluzz.fr from a web browser.

    Make sure that you have installed the most updated version of the Microsoft Silverlight plug-in for your version of OS X.

    In addition, some web browsers do better with Netflix than others.

    I found that Safari Netflix streaming a little restless with the installed Silverlight plug-in. Do not know why.

    I've had better in Netfilix streaming with Silverlight using Mozilla Firefox plugin, instead of luck.

    Try the two browsers to see which works on your iMac better.

    I use an old iMac model. Your new iMac with the new version of Safari can best work for you.

    Just make sure that you have downloaded and installed the most up to the version date of the Microsoft Silverlight installed plugin. »

    Good luck!

    What is the best app/system font to use on Mac OS x with CC?

    Welcome to the forum,

    Most of the software are always not the compatibility list CC for features such as the automatic activation, etc., for example:

    I would contact one of the fonts management companies/developers directly if you have compatibility issues regarding CC and the features that you may have been used to work with in the past, before the release of CC, to ensure that your expectations are accurate at the time of purchase.
