Why my ListView items cannot display on a single line?

 ListView {
       preferredHeight: ui.du(20)
       id: keyItemList
       dataModel: _nao.keyItemList

       leftPadding: 20

           ListItemComponent {
               type: 'item'

                   bottomMargin: ui.du(1.0)
              }
          }
      ]

      verticalAlignment: VerticalAlignment.Center
      horizontalAlignment: HorizontalAlignment.Center
}

If I put prop of listview layout. Items being passed.

If I didn't put any accessories page layout, the elements present, but vertically.

It can be a little difficult to get the horizontal listviews to behave, dimensions should be set correctly if I remember correctly.

See https://github.com/oniongarlic/bb10-hlv-example/blob/master/assets/main.qml for an example code.

  • The display of a single line to multiple columns

    Hello Oracle gurus,
    I am fairly new to the SQL development and hope that someone could help me

    I have an ID that repeated several times in 3 different tables based on a condition

    For your convenience, you can go

    Select a.id,
    B.SID,
    case when b.state = 1 then 'K' another thing ' n end.
    case when c.city = 2 then 'K' another thing ' n end
    PRIM one
    outer join STATE b left on a.id = b.id
    outer join CITY c left on a.id = c.id

    Results

    ID NAME STATE CITY
    1 Peter K N
    1 Peter N K
    Stewie 2 K N
    2 Stewie N K

    An additional line is coming because of Peter, his State Y and Y for the city.
    Expected results
    ID NAME STATE CITY
    1 Peter K K
    Stewie 2 N N


    How can I achieve this? I think I can do a union. but my actual query made 140 columns. so, I'm curious to know if there is another way to address the issue?
    Is it possible to use separate?

  • Why teststand cannot display the ASCII character which number up to 128?

    Hi all

    I encountered a problem on an application for ASCII characters, why teststand cannot display the ASCII character which number up to 128?

    For example: an expression Local.xx = Chr (164).

    XX--> chain, can't do the correct string.

    An idea for this?

    OS: WinXP, SP1 Teststand2012.

    Thank you very much.

    TestStand uses encodings multibyte code page, that you have defined for the operating system-based. If you are using a code page that requires multibyte characters, you should also make sure that you have the Options of Station-> location-> parameter Regcognize multi-byte characters is enabled.

    On Windows 7, at least, the code page of the operating system setting is located in the control panel "Region and language" in the "Administration" tab where it says "language for non-Unicode programs".

    Hope this helps,

    Hello boongsong, I can see the picture now. I see that you're talking about.

    Here a link to Microsoft that may have a fix for the problem. It's worth a try. If Mocrosoft cannot solve it, we can do a bit of research on the question, but I suspect it is perhaps that the Internet Explorer settings may try to block some sites and have a problem to do. I've not seen this before.

    I have Norton, but I cannot in my Internet Explorer or one of the other toolbars. It's just a personal preference, which makes the screen too "busy" to me. I also remove all other icons in toolbars that I don't use. But again, this is just a personal preference.

  • "due to an unidentified problem, windows cannot display windows firewall settings" fixed but still can not visit some sites and the laptop now turns off the coast on me. What should I do?

    I have an Apire one laptop with Windows xp service pace 3. I had to restore it to factory about 3 years ago. Some time after that the sound system began to slow and the Synaptics mouse stop working properly. I can move the pointer, but the left click does not work. It works in safe mode but not in normal windows. I used the Acer eRecovery for correct, but it did not work. I tried to download the driver for the mouse on the internet, but some how it could stop the download. I gave up at tring to fix. Some time in late March or early April, I couldn't access internet and after 22:30. I ran the diagnosis that is provided by internet explore and he said that the HTTP and HTTPS worked but the FTP did not work. AVG later told me my firewall is disabled and there was the possibility to reactivate it and I did. After internet explore stop allowing you to enter certain sites that I wanted to enter, I ran the Diagnostics again and he told me that a firewall client has been the cause of the problem. I tried to control my firewall setting, but had that "due to a problem not identified, windows cannot display the firewall settings". I thought AVG was the problem, so I have unintalled then he returned and attempted to access the firewall but got the same message. I typed in Google MySapce and found this site. I followed a few directions given to others in the thread started by joecarpenter33 and discovered that my firewall has been deleted and Base filtering engine has been deleted also. I downloaded and ran Malwarebytes ANti-Malware and SUPERAntiSpyware Free Edition and tdsskiller. MBAM has found a Trojan. The results of the analysis is less to:

  • Impossible to display the Windows Firewall GET an error due to an unidentified problem, Windows cannot display Windows Firewall settings

    OP: Problem with Windows XP service pack 3__ firewall settings

    When I try to view the settings of the firewall, a dialog box appears saying "Due to a problem not identified, Windows cannot display Windows Firewall settings".

    I read a thread on a file to merge with the registry of XP SP2. I did not like I do not know if it would work with SP3? or should I do something else?

    In addition, why is that happening? What is the problem with the Windows Firewall? If this has happened for some time is a Microsoft patch that can be downloaded instead of trying to make mergers of registry (I'm not very happy to do).

    Thank you
