Error "batteryInfo" has not declared in this scope

Hi, I have this error in my project, I understand the example of the battery of the sample, but I get the error of generation.

It will be something else?

qml->setContextProperty("_battery", &batteryInfo);

for example

qml->setContextProperty("_bateria", &batteryInfo);

or

qml->setContextProperty("Battery", &batteryInfo);

  • error: 'QmlDocument' was not declared in this scope

    I followed along the following:

    And added the following code to main.cpp:

    #include

using ::bb::cascades::Application;

int main(int argc, char **argv)

    AbstractPane *root = qml->createRootNode();
    Application::setScene(root);

}

    When compiling, I get the error:

    error: 'QmlDocument' was not declared in this scope

    Your weird namespace.

    using bb::cascades;

    Try this.

    Edit: Also if I were you I wouldn't want to create a new project and select HelloCasades as a model.  That will be running a lot faster than to try to do it from scratch.

  • another namespace issue? 'CameraSettings' was not declared in this scope

    I have a camera native c ++ application coded and run successfully.

    I want to change the flash mode.  So I add:

    I also add:

    Is it a matter of namespace or a:

    Something else?

    Hello

    I am going through the updated documentation and having problems of implementation of the toast.

    toast->setBody("Welcome to the BlackBerry 10 Cascades documentation!" + "You have lots of space, but your text will wrap around in the dialog box.");

    I guess you missed the variable declaration.

    Declare an SystemToast object in the method itself or in app.hpp like this:

    I use LR 4.4, but it did not work properly since I got my new camera (Canon 70 d). When you try to import, I get the error message "Preview not available for this file. I got lucky better connection of the device with a usb cable, which allow me to see the jpg images, but he wouldn't let me see the raw images (.cr2). I would solve this problem by opting for the LR5?

    You can disable hibernation if it is enabled and you do not...

    When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

    -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
    -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
    -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

    You can control the amount of space your system restore can use...

    1. Click Start, right click my computer and then click Properties.
    2. click on the System Restore tab.
    3. highlight one of your readers (or C: If you only) and click on the button "settings".
    4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
    5. click on OK. Then click OK again.

    You can control the amount of space used may or may not temporary Internet files...

    Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

    -Open a copy of Microsoft Internet Explorer.
    -Select TOOLS - Internet Options.
    -On the general tab in the section 'Temporary Internet files', follow these steps:
    -Click on 'Delete the Cookies' (click OK)
    -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
    -Click OK.
    -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).
    -Once it's done, click OK, close Internet Explorer, open Internet Explorer.

    You can use an application that scans your system for the log files and temporary files and use it to get rid of those who:
