• Difference between C/C++ Native Development & Cascades QT C++ development

  What is the difference betwwen development C/C++ native development & C++ QT Cascades.

  I assume you're referring to Kits SDKS listed on this page:

  https://developer.BlackBerry.com/DevZone/platforms/BB10

  C/C++ native Development Kit is everything you need to encode a native C/C++ application to run on the BlackBerry PlayBook and the next BlackBerry 10 devices. The API described should give you everything you need to develop all the components of your application, from the ground up. If you have an existing application, you can probably start here. This SDK is ideal for access to the low-level API.

  However, it does not come with a user interface toolkit. You have literally everything code yourself, or help existing libraries to the port for you. You probably don't want to do. Instead, you can watch the C + c++ / Qt Cascades Development kit. This SDK provides you with everything you need to develop an application for BlackBerry 10 devices to come. You can still access all the low-level APIs, if you need it, but because Qt adds so much and is so powerful, almost everything you need is probably already there.

  Basically, Qt will provide you with the API call and use in your application. These libraries are open source which have been reviewed for many years and will probably accomplish everything you need. Go further, Cascades is the toolkit of user interface of choice in the native development, as it offers UIS amazing, fluid and easy implementation in your application.

  Note that I never mentioned the PlayBook by discussing the C + c++ / Cascades of Qt kit. The PlayBook is not supported with native support for this mode of development, but it will come with 10 BlackBerry is released later this year.

  Basically, the native C/C++ SDK provides you with the nuts and bolts, you must develop an application from scratch. But why would you, when C + c++ / Qt Cascades Development kit includes many libraries for things you probably want to do.

  Unless you develop a game, a porting library, or the need to develop for the PlayBook today, using C + c++ / Qt Cascades development kit.

• How to implement QtSoap in native development of cascade?

  Hello

  I want to ask you something QtSoap implementation. I use QtSoap to parse the Web services *.asmx files. I include qtsoap.h and qtsoap.cpp from external sources, but I can't find the libraries.

  Can you help me solve this problem and how to implement QtSoap in native waterfall?

  Thanks before.

• question about developing native applications

  Hey there,
  is it mandatory to develop a native app - c ++ stuff is essential to work with qml or can we develop the whole project only with qml coding... ??
  . S

  very probably the button calls a method from a class c ++, in the samples probably from applicationui.cpp.
  check if the called method exists and is marked as q_invokable.

• Cascades bb10 take screenshot with level API 10.0

  Hey everybody,

  Is there another way to take the screenshot by code?

  I read this post http://stackoverflow.com/questions/13123438/how-to-programatically-take-a-screenshot-on-blackberry-1...
  and I read this too https://developer.blackberry.com/native/reference/cascades/bb__system__screenshot.html

  But I need to take the screenshot with 10.0 minimum API level.
  is there another way to do this?

  Thank you

  Less the required permissions the less chance that someone won't use it had to 'trust' of the questions.

  I've attached an example of this you can check it out, she mainly only takes full-screen screenshots.

• Incorporation of a control "web view" in a native application

  Something I wanted to say to ask the NDK experts this week but I forgot: it is now possible to integrate a web browser in a native application, similar to how this can be done via a web control in Adobe AIR applications?

  Cascades is currently provided as part of the SDK BB10.  The plan announced publicly, is that BB10 will be available on the PlayBook sometime after that BB10 phones are released later this year.  I can't speculate on dates.

  And can't I speculate on the question of if the waterfalls will appear publicly in a version of the pre-BB10 PlayBook software.  We know only what is known

  I asked webview native non-Cascades and I was told that is not available today.

  See you soon,.

  Thanks for any help.

• Can we get an example of application in CORE NATIVE and WATERFALLS in blackberry-10?

  Good day to all,

  It's too late to ask this question.

  (NOTE: I asked this question in native development Forum also, because I don't know where I have to ask myself this question.)

  I need a sample application (such as 'Hello World') for the CASCADES and CORE NATIVE, to know how to start the NATIVE application. Because when I create a sample app by choosing

  FILE > NEW > BLACKBERRY PROJECT > APPLICATION (application type) > screen/empty (I chose the language in C++), but it provides 'main.c' not the "main.cpp" and I have not a clue of how to grow a single screen according to I have to start the implementation.

  I think you all understand my problem.

  Hi all

  I get the solution here (dishooom replyed on the same question that I posted in the Native Development Forum):

  Thanks to dishooom.

• How to use the property PivotX and PivotY in cascades

  Hello

  My goal is to rotate the line on my angle.

  

  1 I received two points: A(x1; y1) and B(x2; y2).

  2. I calculated the size of the vector AB and angle of point A:
  AB = Math.sqrt (Math.pow ((x2-x 1), 2) + Math.pow ((y2-y1), 2));
  Alicia = 44 *.

  3 I put in place the line on the terms of coordination (width = AB, height = 3px):
  myLine.layoutProperties.positionX = x 1;
  myLine.layoutProperties.positionY = y1;

  4 I turn the line on the angle that was found.
  The starting point of the line must be the point A, endpoint - point B. But I have no =)
  I try to use the rotationZ, but I do not know how to work with his propertyes PivotX and PivotY.
  Default 0 PivotX and PivotY = 0. When I try to set up PivotX = x 1 and y1 = PivotY I get the incorrect result.

  With PivotX = 0 and PivotY = 0 I get it (myLine.rotationZ = 44):

  

  Please, help me =)

  That could happen, because the pivotX and pivotY zero definition makes the rotation around the center of the element. In the case of this image, which is equal to its center point (300, 1.5), but no, it is top left. Try to set the pivotX to-(image.width/2), which will be:-300; pivotY to the-(image.height/2), which is - 1.5; and then turn again.

  Please see the details on this subject here:

• work with libraries of fragile Cascades

  just found out HowTo create a library project and how to use it

  See this thread: http://supportforums.blackberry.com/t5/Native-Development/Cascades-Library-lost-in-space/td-p/270240...

  But in the meantime I don't know if it's really a good idea to use library projects because they seem to be fragile.

  Problem: Moving location of the library project

  After completing the work of the library, I created a GitHub project,

  This cloned on my drive

  copied the existing content of the Eclipse project inside the workspace

  committed/pushed to GitHub

  then I did what I always do:

  closed the existing project into workspace

  deleted project

  to be sure of the restarted Momentics

  Project to import (Github) in the workspace (without copying)

  and to return the library project by using the same name as before

  only difference now: the project is not stored inside the workspace.

  its location is now outside the workspace

  Library project compiles fine, but... Application compiles more, get errors like

  make -f Makefile.Debug
  make[2]: *** No rule to make target `/daten/bb_workspaces/cascades-api-10-1/baastestApp/../baasKinveyLibrary/arm/so.le-v7-g', needed by `o.le-v7-g/baastestApp'.  Stop.
  

  Tried to create a new project, added to the library, added assets as described in the other thread, I mentioned above. WORK

  Back to the other project. tried to add the library again. There is no update option, no option to delete.

  Then I noticed that he was inside the .pri entered INCLUDEPATH for two library sites.

  Discovered that in general C/C++ project properties | Paths and symbols in Assembly and GNU - C there are now two includes. removed a wrong pointing it at the old location inside the workspace.

  Clean up / re - index / build does not help

  INCLUDEPATH and DEPENDPATH now both are ok in .pri, but under the LIBS and PRE_TARGETDEPS, yet there are two entrances. I don't know what I have to change to get them far. Remove .pri does not help because .pri is generated

  any idea? "

  problem: bar - active descriptor.xml by configuration

  While comparing projects that I noticed that the files added to device-Debug, device-release assets, etc., pointing to the library project are not ok.

  If I understand right, they should always point to the corresponding configuration.

  e.g. for debugging the device, tap on... arm/so.le-v7-g/... and so on

  Seems that the add-on-Library Assistant added that randomly. I fixed that. Now I'm knowing: after adding a library to check if the assets are added correctly for each configuration.

  BTW: In the thread above I asked get HowTo of the project of library built for all configurations. It's actually easy: Build Configurations | Build all... on the library project

  ---

  Hope someone can tell me how to replace the reference to a project of library if the situation has changed. Or how to remove a library, and then add it again.

  THX

  do some tests it is how I now use libraries of stunts.

  the goal:

  develop the library and one or more projects of cascades project using the loibrary in your workspace

  the library may not contain C++ QML as well as other assets such as images

  There are two steps:

  • Create the library project
  • use the library of another project of cascades

  Library project

  as a library template I import the project provided by Isaac Gordezky on Github

  https://github.com/BlackBerry/Cascades-community-samples/tree/master/Cascades-library-template

  Please only impiort the "MyLibrary" project in your workspace

  then prepare the template for this library project. in my case, my library project is named baasKinveyLibrary

  • Rename the project in baasKinveyLibrary
  
  Edit the Makefile file: QMAKE_TARGET = baasKinveyLibrary
• Edit mylibrary.prf: baaskinveylibrary {... LIBTARGET = baasKinveyLibrary...}
• Rename MyLibrary.pro to baasKinveyLibrary.pro
  Rename mylibrary.prf to baaskinveylibrary.prf

Delete the content of

• / SRC
• / include
• liabilities

Copy your content in the library project

• copy your .cpp/SRC
• Copy your all in / include
• Copy your assets into liabilities
• If you need other libraries, edit baasKinveyLibrary.pro. (I did: LIBS +=-lbbdata - lbb - lbbdevice)

Library project should now compile

Waterfalls of the project using the library

It's easy:

Configure | Add the library | Library in the workspace project

Select your library project

If you have included assets:

Change bar - descriptor.xmp | Assets | All the Configuration

Add a folder, and then select Workspace the active folder of your library

you will get an entry like this:

${workspace_loc: / baasKinveyLibrary/assets}

You can now use your library

Problem: remove the library

Unfortunately there is no wizard to remove a library, so in case you want to remove it, here are the steps:

• bar - descriptor.xml: remove Active reference library - active and all the configurations of the reference to the library
• Project properties: delete the reference to the library project
• Project properties: remove includes your general C/C++ library | Paths and symbols in Assembly and GNU - C for all configurations, also references uncheck the library for all configurations project
• Narrow Momentics, .cproject open, look for "baasKinveyLibrary" and remove all theitems where your library was referenced. You should find 4 occurences

now to create the project, open the .pri file - there should be no reference to your library

I'll blog on with screenshots in a few days. ... and open a topic in order to provide a Wizard 'Delete Library' ;-)

• Detect if stunts or native on the compilation or execution

  Is there a way to detect if the app is built (or built) in native or cascades? I want just the size of the screen like this: http://supportforums.blackberry.com/t5/Native-Development/how-to-get-resolution/td-p/2649643

  But to select the corresponding function if its native or cascades automatically.

  Or is - this one works on cascades also native?

  Thank you

  Cascades relies only on the native stuff. All the native stuff is still available in a Cascades app thinking that it is a superset of the available API.

  In any case, this post was not a 'no', he was one of the many different 'yes' that apply. I tried to keep it simple because I do not understand half of what you ask... you do not mention a loadable library initially, looks '(windows)' sort of place given the context here. A that the use of 'windows' related to the operating system of Microsoft, or something else?

• Date picker, native SDK

  Hey all,.

  I would be grateful for the help implementation of a DatePicker using C++, y at - it is a native component on the central part of the SDK as DateTimePicker for the stunts?

  Regards and thanks in advance

  I think that you are yourself, then you will have to create your own using either Qt functions such as QDateTime for example...

  http://developer.BlackBerry.com/native/reference/Cascades/QDateTime.html

  or the standard library of C/C++ functions.

• Change notifications / ringer VOLUME by programming?

  Hi guys,.

  Does anyone know a way to change the volume of notifications to the active profile?  I don't mean to change to a different profile, I need to change the level of the level of the master volume of the current profile, i.e. the value of the volume slider programmatically you can see at the moment where you go to settings / Notifications screen (it's the main notification volume level used for all sounds unless the user overrides it to specific applications or specific types of notification) or that the user can change volume up/down buttons if they are defined in volume rather than multimedia volume change notifications.

  I checked the Panel Manager, audio mixer audio libraries etc. and I find how to change the volume of all EXCEPT notifications...

  Your help will be greatly appreciated!

  The bb setVolume method: platform: NotificationGlobalSettings class, that's probably what you're looking for.

  Here is a link to the documentation:

  https://developer.BlackBerry.com/native/reference/Cascades/bb__platform__notificationglobalsettings...

  Hope that helps.
