Support different OS

I have read many topics on the different versions of the operating system, but I have a few questions. Unfortunately I don't own a Blackberry, so what I did is done by simulators.

I'm totally new to Blackberry App programming, so, when I started I downloaded the plugin Eclipse with Blackberry JRE 5.0.0. At that time, I had no idea about the different versions. If my application has been tested on simulators that came with the plugin.

First of all, I wonder about the font sizes. I noticed that the standard font size seems to differ in different simulators. Is that the case on the real Blackberry? Can the user change the default font size that will be the effect on my application? If this is the case, I need to force a specific, is font size - this possible?

Also, I used a number of things that have been introduced to 5.0, IE screen transitions, TextSpinBoxFields and BrowserField. I stopped the transition of the screen if an earlier version of the operating system is detected, but I am yet to repair the TextSpinBoxField or BrowserField. Any advice on alternatives would be appreciated. I looked at the BrowserDemo using private, but I can't load a page in the Simulator, so I'm not sure about this.

I also need someone to help me test my application in a Blackberry before I submit AppWorld. If someone would be willing to help me I would really appreicate it. I don't expect to do it for free.

the user may change the font size in the options. It can be very big - but if a user decides to use a huge font you can decide not to support.

defining a fixed font is possible using Font.setDefault. It is not taken into account in all workplaces, in my view, search the forum for more details. IIRC that setting etc. do not meet the menu entries.

You can see in the API documentation in which version of the OS, the component has been introduced.

screen transitions are possible before, but must be done manually, I would not say that as a beginner.

a textspinbox can be replaced by other fields without much hassle I think.

You can use the preprocessing to have a single code for several generations.

  • Support different device sizes.

    Hi all

    I need a support to Q10 and Z10.

    the UX and UI are provided by a third party, and they want the user interface to be a little different for Q10 and Z10.

    I went thorugh the documentation in this respect and found this:

    https://developer.BlackBerry.com/native/documentation/Cascades/best_practices/resolution/using_stati...

    This, I understand that, we can use QML different for different screen sizes.

    but I develop ui in CPC mu... so is it possible to do in CPP too?

    Help, please!

    There is no folder for C++, so what would you put in?

    So yes, or use a thin layer in a qml file, as suggested.

  • Single column supporting different FK of various tables [Design issue]

    What would be a good design for a table with a column that can be worth a few different tables FK.
    The Fk constraint doesn't have to be applied.

    My thought is to simply make an int with another column in the table that defines the origin of the value.

    Is there a better way to do it?

    Thank you

    If the FK column in this table must exist in the table of a parent or another? Hmmm. As FK relationships must be able to be provided by the database to be useful, maybe...

    Create two columns, one for the FK to one parent and one for the FK to parent b. You can then declare the FK relationship in the database so that it can enforce and make profit in the optimization of queries. Then add a check constraint to the table to assert that none of the columns is null, and only one of then has a value (while the other is null). Outer join to both tables parent with a DECODING on the query returns the appropriate parent (research) value of the result set.


    SELECT c.col_a,
    DECODE( p1.col_b, NULL, p2.col_c, p1.col_b )
    FROM child c,
    parent_a p1,
    parent_b p2
    WHERE c.id = p1.c_id (+)
    AND c.id = p2.cid (+);

  • Satellite L40 - is it supports WPs on Netgear Wireless N Router?

    Hello

    I just bought the above to use with my Satellite L40, does anyone know if the laptop wireless adapter supports WPs?

    Thnx

    Hello

    I think you should check what card WLan using your Sat L40.
    The point is that books of L40 can support different network cards like Intel, Atheros or Realtek Wlan card wireless.

    Check Wlan card model and research Web sites for details of the hardware manufacturers.

  • Satellite A350D - 20K does the built-in 3G modem support?

    Hello Sir/Madam,

    I'm just cleaning can turn up when I removed the battery in the back, I saw a small slit looks like a slot for a sim card...

    below the slot, there is a small design resembles a sim card from a cell phone inside the drawing, there is a word sim and an arrow pointing to the small slot.

    What are there? What is this slot for? How will you use it?

    Thanks in advance!

    Hello

    AFAIK the A350D - 20K does not support the 3G module.
    It supports the internal BT module and card Atheros Wlan.

    But I know different notebook series support different hardware specifications. This means that some of the A350D could support 3G and so this slot would be available. Maybe all series uses the same chassis, but not all come with an internal 3G module.

  • error mess. No supported cpu and the computer turns off

    I have a hp p6210y.  I took my computer and looked at herself, and the guy told me that my motherboard was likely bad.  He told m that the motherboard of the computer are bad and he advised to do not to buy a new one because it will go as bad.  My motherboard is a pegatron m2n78 - la.  It has an AMD athlon ii 620 quad-core. Well, I found one on ebay for about $100.  After that I put the new one where said pegatron m2n78 - la on it like that old one does.  I did put in the new processor.  The only different thing I noticed was as soon as I put on it instead of hp compaq said.  I'm a noob to all this.  The first I guys I listened to said that it was the hard drive and it has not fixed this is why I had in the type of computer and started to do myself.  Its been a learning experience for me if I look at the positive side of everything.  But now I have an extra hard drive new (seagate sv35.5 500 GB) sitting on my desk. Do I have to get a power cord with it also. I have the sata cable or whatever.  or I can run 2 hard drive at the same time.  Thank you very much

    FYI... simply because the replacement motherboard has "M2N78 - LA" printed on it, does not mean that it is the same as your original plate. HP has a least 4 different motherboards all models "M2N78 - LA" but named Viola, Violet, Violet3 and Violet6. These motherboards can support different processors, socket, extension and ports of i/o slots back.

    Here are the specifications of your desktop HP Pavilion p6210y and its M2N78-(purple) motherboard. Please make sure that the motherboard is good. Given that HP sells computers under the names of the HP and Compaq, you may see Compaq or HP screens 'splash' at the start of the brand. Although this should not affect the operation of the computer, the lack of good 'tattoo' can prevent you from using your recovery disks.

  • I want to clone my hard drive and this clone allows you to configure a new computer, how do I do this for several PCs with different versions of XP?

    I am trying to replace 15 PCs.  They all have XP because their BONES, bought with different SPs at different times.  They all have been updated to SP3...  They have all MS 2003, upgaded to MS 2007.  I would use a clone as image.  I do not support different key codes?  Although the XP are authentic, I may not all key codes.  My predessor has not keep good records, and stickers on some had labels of Vista.  Even if the PC was bought with XP downgrade.  I need to use XP because of some other software requirements.

  • Different layout for phones BB10 and PlayBooks?

    Hello

    In point 4.1.2 Android, I use "provision" and "release page-sw600dp" files to differentiate the schema xml for phones and tablets. However I can't use it to 2.3.3 as they began to support such feature of 3.2. And anyway, it does not affect that android is concerned because there is no Tablet out there with Androd 2.3.3 of.

    But BB10 phones and tablets support only 2.3.3 runtime. So is there anyway that I can declare different presentation for phones and PlayBooks in a single application project? Otherwise, I need to make two different applications to phones and one for tablets. Please let me know what is the best way to support different screen sizes.

    Thank you

    Knockaert

    You can use the page-xlarge for PlayBook and layout for phones, as you would to support honeycomb devices and phones in one application.

  • Deployment on different device versions

    I would like to add a feature that requires ApplicationIndicator. So far, I have been programming for the 4.2.1 API and need for backward compatibility to this version.  ApplicationIndicator was not introduced before 4.6.0.  I would rather not confront users with the choice of the installation of two buildings separated according to their version of the OS. So, ideally, I would be able to create and deploy my application in such a way that it only tries to access the ApplicationIndicator if it is running on 4.6.0 or higher.

    After reading "how to-develop applications for BlackBerry Device Software versions and models of BlackBerry smartphone" (http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800451/800783/How_To _...), I'm still a little confused about my options.

    The section "Using libraries to support different implementations", seems to be maybe a solution. Is it? Otherwise said, it saves you from the obligation to offer multiple versions of your application, or it's simply a way to reuse the code in an organized way? Article provides many examples of code, a lot of details, like how to implement compile paths and "References of project" - what are doing by the way?-are absent.  Also, what is the end result of that look of the approach regarding files jad and cod for the deployment?

    Thanks in advance,

    Neil

    Yes. The BB-browser user-agent header contains the device model and the level of the BONE.

    If I understand you correctly, this is not true: you can create storage with different blocks and create objects in their breast.
