How to upgrade qml component an act any

Hello

I need to display the remaining battery time. I tried to put some battery_info in their context but couldn't as long as it's not QObject. I need display the calendar in real time on my qml. How can I do

Since you obvsiouly works on a sort of 'remaining-battery-life' - app. I will try to explain, in general, what you can do.

First of all, you have your loop that checks for the remaining duration of the battery. You can either:

  1. keep looping and settings of the user interface for each loop (not a good idea!)
  2. Register for events and define the user interface on each event (best idea, but do not know if this is possible)
  3. Run the UI definition and method determineBatteryLifeRemaining every minute. (Variant 2)

To update your qml components, you can only access from C++ and set the text. Small example how to proceed:

QmlDocument *qml = QmlDocument::create("asset:///MainMenu.qml").parent(this);
navigationPane = qml->createRootObject();
TextArea* batteryText = navigationPane->findChild("batteryText");
batteryText->setText("Nominate ZeZke for BB Elite!");

    "

    So, is the solution to my problem. How to upgrade?

    Hello

    First of all it is a user to user forum and you won't find anyone from Toshiba.
    Secondly, as far as I know that your device was designed for an American market and if you are looking for drivers or updates you must use a Web from Toshiba site we:
    http://www.CSD.Toshiba.com/cgi-bin/TAIS/Su/su_sc_home.jsp

    If you have any problems with your unit, so you must contact the ASP (authorized service partner Toshiba) in your country.

    As far as I know that Windows Vista is not official on the market. Maybe the end of the year or next year.
    I can t believe that you are not available to install the updates. I checked a few comments and Microsoft updates have always worked.

    As I suggested at the beginning if you have some problems with your unit has so contact the service of Toshiba.

    How to upgrade to Version 10.8.5 my MacBook Pro software version 10.7.5

    The latest version of Mac OS is 10.11 'El Capitan' and the upgrade only currently available free. Any computer capable of running 10.8.5 will run 10.11. My son and I both have the same model of MacBook Pro you and executed both El Capitan without problem. I upgraded my RAM 8 GB but its still has the original 4 GB and shows again no problem.

    Any successful upgrade means that you must be free of any antivirus, internet security or so-called applications of "cleaning/optimization/tune-up. They will destroy the performance.

    If you MUST have 10.8 you must buy it on the Apple store online (not the Mac App Store application on your computer). The purchase to the store link is here:

  • How to upgrade my Firmware for printers?

    Hello

    I'll post a quick tutorial on how to upgrade the firmware for your printer.

    Whatever printer you have to do most of your print, there are a few things you can do to ensure that it runs optimally. According to the model and printer ship date, you can have a few updates to make as your printers may not have shipped with the driver or the most recent firmware.

    There are many reasons why these updates are important. Driver updates will make your printer run more smooth and faster from your computer or the printing station. They will also update Media preloaded into the pilot that they become available on the market, so that you can easily print on these materials.

    Firmware updates also make sure that your printer works more fluid and faster, but this applies to the material itself. Firmware is only the software that is loaded in your hardware. Latest firmware updates for some models of printers decreased paper and ink waste and increased print speeds.

    Now to download the latest version of the software that you will need:

    1. Go to HP.com support & drivers
    2. Click on the green box
    3. Type the product number of the printer that you have
    4. Select what OS you have on the desktop / laptop
    5. After that, you can go ahead and get the latest version of the software that are available on the list.

    Remember if you find one of my post useful or want to say thanks don't forget to click the White Star under my name to give me congratulations.
    I really appreciate it!

    Once you install the firmware, it will give you a list of instructions on how to load the update to the printer.

    Let me know if you have any questions.

    Thank you!

    I hope it's useful!

    Thank you!

  • Satellite U300 - how to upgrade the BIOS on a Linux system?

    Attempt to update the BIOS of my U300-153, which is described as an operating system independent on the download page, I find that the upgrade file is provided in
    http://Support1.toshiba-tro.de/Tedd-files2/0/BIOS-20090304140640.zip
    does not include the files to create a bootable CD, as described in the instructions to the
    IOS http://eu.Computers.Toshiba-Europe.com/innovation/FAQ.jsp?z=234&service=eu&from=faq_selection&CFID=B & FID = TRO0000000b07
    where Option 2 step 2 lists the files that are in the zip, and they are required to make a bootable cd. The files listed are not in the zip.

    It forces me to use Windows. My Windows is broken and I can't fix it, because Windows repairs destroy data (clearly indicated on the packaging of recovery CD) and installations of Linux. My Linux works very well, and I don't want the windows more.

    So how can I upgrade the BIOS? Either:
    1. use a true independent bundle of BONES (ie the promised approach of bootable CD). I can't find such a thing here.
    2 reinstall Windows, which trashes the laptop.

    Any suggestions?

    Sincerely,

    Another point of view - I bought MS Windows XP Pro and haven´t you have a PC to install it on. Can I install this OS on my Satellite? Will it work? Where can I find the drivers for touchpoint etc etc... Normally, the Toshiba works with Windows ME and I can not use ITunes on ME... if XP would be great - what do you think?

    Hello Jürgen

    In my opinion, if you install the operating system on the unit you you use the recovery CD provided because it has been tested and it works without any problem. But if you want to install another system on your laptop, you can use the original Microsoft OS and all the necessary drivers, you can find the Toshiba site.

    You need Virtual WiFi:

    You may not have that unless you try to connect to other WiFi devices via your computer and
    many WiFi devices and their drivers do not correctly support the virtual pilot.

    Check with the manufacturer of system and/or support updated real manufacturer Sites and WiFi device drivers.
    (Which is also updating the driver virtual.) If no new drivers WiFi are available then re - install the present
    one.

    Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
    version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
    Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.

    Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
    Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
    BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
    each installation.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
    http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

    Installation and update of drivers under Windows 7 (updated drivers manually using the methods
    below is preferred so that the latest drivers from the manufacturer of system and device manufacturers are
    found)
    http://www.SevenForums.com/tutorials/43216-installing-updating-drivers-7-a.html

    Download - SAVE - go where you put it - right click – RUN AS ADMIN.

    You can download several at once however restart after the installation of each of them.

    After watching the system manufacturer, you can check the manufacturer of the device an even newer version.
    (Those become your fonts of rescue system manufacturer).

    Repeat for network card (NIC) and is a good time to get the other updated drivers as
    Windows 7 like the updated drivers.

    ==========================================================================

    More information on what WiFi devices a virtual: (as noted above, if the device or the driver is not
    support the virtual device or is not required then it can be disabled).

    The WiFi device and the driver is installed must support a Virtual WiFi configuration. Check with the system
    Manufacturer support, their documentation online and drivers and ask in their forums (if any) known
    questions. If the wireless device is supported for OEM sound drivers, visit their site for updated drivers and
    known issues (Intel, Realtek, LinkSys and others).
