indicator problem ListView and activity

Hi, I was playing around with the sample application address book so that I have included a button to re-populate the list view. It takes a few seconds, that's why I've included an indicator of activity runs while the list view is being filled.

The activity indicator is supposed to start when the button is pressed and stop when the display of the list has been entered.

Now, my problem is that the activity indicator seems to start when the display of the list has been populated (it just starts and stops in a Flash). I have also included a header which changes the onbuttonclicked text to check if that was the problem-indicator of activity but same thing happening (text only changes after listview is filled). The list view appears to stop all operations until it was settled.

What is the cause and how can I solve this problem? Thank you.

onButtonClicked {}
change the header text
start the activity indicator
fill listview
}

Then in c ++ after m_model-> insert (map) I emit a stop to the activity indicator signal.

Indicator text and header activity does not change until the listview has been briefed.

as the list of all the opinions of the population occurs on the event thread indicator gets no time to do things.
If you would like to fill in the asynchronous list, it should work as expected.

as a sidenote: have a look to refresh the headers, they are often used to reload a list.

  • I have a problem with the active WiFi Seagate GoFlex TV Media Player asking for a net user ID and a password.

    Original title: Net User ID & Net password

    After the upgrade from Vista to W7-64 CV, I have a problem with an active WiFi Seagate GoFlex TV Media Player asking for a "Net User ID & Net password" to log.  I used all imaginable combinations of IDs & passwords, but they all lead to logon fails. I'm almost certain that it is a W7 security problem because others with the same players who went to W7 face the same problem.  I found many supposed fixes online, but none works.

    I am aware that MS W7 works as it should and Seagate is not their problem, but if anyone can recommend a change of security to help this issue, I guarantee a pass towards the sky.

    PS: All the sharing, etc. continuously.  are installed as they should be.

    The only reference to Net User ID and password I can find is on page 46/47 of the User Guide. If this is not the user name and password of the Windows account that you want to share files with, I don't know what it is.

    I guess patches that you tried to include those that are mentioned here:

    http://forums.Seagate.com/T5/FreeAgent-theater-and-GoFlexTV/logon-fail-home-network-Windows-7/TD-p/70540

  • After a clean install of Windows Vista, Intel Wifi card is installed and activated, but does not detect the network.

    Wireless card not working after a clean install of Windows Vista

    I did a clean install of Windows Vista Home Premium on my HP Pavilion of 32 bits. I've completely updated Windows via Service Pack 2. Given that the clean install, my wireless card, Intel (r) Wireless WiFi Link 4965AGN, was not able to detect all the networks. The Wifi card is listed under NICs as being installed and activated. the hardware on my laptop Wifi switch is set on "on" and the light is blue, indicating that the card is working.

    I can connect to the internet if I connect physically my computer to the modem with an ethernet cable wireless, so the modem isn't the problem. Other computers can connect to the wireless modem, so my Wifi modem functionality is not the problem. The problem with my computer.

    I tried to uninstall the Intel driver and reboot my computer with the generic driver. Install the driver generic, but my wireless card has not always worked. I then ran an update of windows, nothing helps.

    I tried to install the "Intel® PRO /? Wireless and WiFi Link"drivers for Windows Vista (32-bit 13.1.1.1 the latest version and the previous version 12.4.4.5 32-bit) for the Intel® Wireless WiFi Link 4965AGN directly from the Intel Web site at http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Wireless+Networking&ProductLine=Intel%C2%AE+WiFi+Products&ProductProduct=Intel%C2%AE+Wireless+WiFi+Link+4965AGN. The map didn't always work with a driver.

    In addition to the pilots, I also downloaded a tool of diagnosis of Intel (Intel® PROSet /?) Utility of WiFi wireless connection for Windows Vista 32 -? Bit). Said diagnostic tool the WiFi card is not installed or enabled, however, Device Manager maintains that he is also installed and active.

    Is there a problem that causes Device Manager to say that all is well with the card, but does not map to realize that they diminish the radio signals? Everything's fine, diagnostic, it just does not detect networks around him. Help, please.

    Hello

    The on/off switch actually works?

    Since it is an internal adapter to ensure it is enabled in the settings of configuration/F2 (BIOS/CMOS) often like you
    Start - so look at the screen.

    Have you tried the computer on other WiFi networks? You had a WiFi type problem before the
    Re-install of Vista?

    ---------------------------------------------------------------------------------------------------------------------

    Your router could be suspicious here, you have successfully updated its firmware as a possible solution? And I would like to
    Update your WiFi drivers on computers. How you are positioned in the router? Are there
    obstacles in the path?

    Actually try updating your driver and disabling the network logon.

    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.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    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. (The
    manufacturer of system become your backup policies).

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

    I would also turn off auto update for the drivers. If the updates Windows suggests a just HIDE as they
    are almost always old, and you can search drivers manually as needed.

  • BlackBerry SYNC Q10 problems detected and explained - BB should deliver difficulty ASAP

    I see that many problems with the synchronization of GMAIL accounts, calendars, contacts, etc. After the short debbuging here is what I noticed for IMAP, ASync / Pop/SSL:

    -If set you up accounts and stay only on providers of wireless DATA CHANNEL (active), everything should work fine

    -If you are connected to only ONE WIRELLES access point and do not miss the connection (if you will pass you to the MS DATA and NOT connect message) everything should work properly.

    -If you are on the ISP AND active wireless data and that you are moving around town or driving BBQ10 alternate known AP/s and SP data to which case your CHUTERA SYNCHRONIZE. In the case of sam (very rare) it will recover, but in most cases, you will need to restart BBQ10 or enter in the accounts which will be indicated in red that it cannot connect to the server. Reboot will solve the problem until the next switch network (wireless or data), you'll have to do it again. Another solution is within the account (where you can see red notice that there is no connection to the server) manually revalidate account by adding the password which is hassle, but you can set PUSH to OFF than SAVING as well and you'll see talking to the server account and you will be brought back online in CONNECTED to the switch mode following the network. If you need PUSH just put back and save - again once he's going to talk to the server, save the setting, you'll push back service and account will work until the next data channel jump...

    It is constantly on ASync and IMAP (Gmail) and somewath less spoted on POP/SSL. POP/SSL is little more resistant to this question, but just a little.

    If you have for example 5 accounts, you will need to go through above steps each time as your network connection (DATA/WIRELESS) Q10 changes... :-(((

    At the moment I am using only the - No. WIRELESS - DATA SP mode and hope BB team is reading this and fix this ASAP as HUB of BUGGY and please give as some CONTROL of TRAFFIC of DATA.

    Thank you in advance.

  • Lenovo G510 problem wifi and ethernet

    Hello!

    I have two Lenovo laptops, G50 and G510. The first works perfectly except the second after 10 months started yesterday which have problems with the network adapter.

    The Wi - fi button is grayed out and cannot be opened and the ethernet port can not read any cable. I tried all the solutions I found on the web (deactivation and activation devices, uninstalling and reinstalling the drivers, updating the system and the system format) but failed. The ethernet adapter does not appear in network devices after the restoration of the system to its point original (format), even after installing the drivers for the network card I found in Lenovo support site. And all this happened yesterday when the only change in the system was a windows update. However if this was the problem of the restoration of the system, update and format should have fixed the issue.

    I used windows 8.1 but now after the format I use 64-bit windows 8. Could you give advice? Could this be a hardware problem? I'm desperate here.

    Really weird that both had fault at the same time. Try the following out the battery and the power source and press the power button without any power supply 5 times. And restart again.

    If not try to work the boot in safe mode with network and see what is happening here. In the login screen hold down SHIFT key and choose reboot option. you will see Win8 advanced options.

    I'm having a problem in the activation

    I am trying to enter the key but it says try again a new key, I have reinstalled windows on my pc when I bury the key, it is said, what can I do?

    Is it an upgrade license? If so, try the following:

    Skip entering your product key Windows 7 and complete the installation.

    When you reach the desktop, click Start, right-click on computer

    Click on properties

    Scroll down to the Windows Activation

    Click the link x days before activation.

    Click on the link that says: "show me other ways to activate.

    Enter the product key

    Select the Activation of the phone

    Click Next when you enter your key page

    Select your country

    Click Next, call the number listed

    Be sure to explain your situation to the Appeals Officer.

    Provide the installation generated when ID requested by the call agent

    They give a confirmation ID in return, enter it

    Click next to complete the activation.

    However, the requirements for the media upgrade is that you have an operating system already eligible such as Windows XP or Vista installed to use it. Since the Windows 7 end user license agreement.

    15 UPDATES. To use upgrade software, you must first be licensed for the software that is eligible for the upgrade. After the upgrade, this agreement takes the place of the agreement for the software that you upgraded. After upgrade, you can no longer use the software that you upgraded.

    So, if you are always denied, you will just have to reinstall Windows XP or Vista and let it do the verification of eligibility.
