already, add this in main.cpp

qml->setContextProperty("_app", this);

I get an error

asset:///CustomComponent.qml:7: ReferenceError: Can't find variable: _app

is this a bug or the context property can not be access on listitemcomponent?

Well, you can hang you want global variable of Qt . You can try something like this:

hand. QML

Page {
   Container {
      ListView {
         listItemComponents: [
            ListItemComponent {
               type: "item"
               CustomComponent {
               }
            }
         ]
      }
   }
   onCreationCompleted: {
      Qt.app = _app;
   }
}

CustomComponent.qml

 

import bb.cascades 1.0

Container {
    Button {
        text: "Custom Container"
        onClicked: {
            Qt.app.showMessage("This is a test")
        }
    }
}

    A "Cannot find...". ', ' Failed to start..., "Could not load..." ». "Might not work... "" Cannot run ""error loading... ". "or"specific module could not be found"message is usually related to the malware that has been configured to run at startup, but the referenced file has been removed after a malware scan, leaving behind a registry entry pointing to a file that does not exist.
    It might be a removal of malicious software or an application not installed.  The entry may have a curious looking name since it was probably generated at random when the malware was installed.
    Windows attempts to load this file but cannot locate because the file has been deleted for most probably during a scan for malware. However, an orphaned associate of remainders of startup parameter or registry entry and tells Windows to load the file when you start or connection.
    So you should delete the referenced entry Windows stop trying to run the file. It may or may not be included in the registry.  Autoruns (see below) you get the elements no matter where it is.
    If you just locate and uncheck the item in msconfig, which disables the element but does not remove the reference to the element of false starting your computer.   Disabling in msconfig it is the old mans solution (or the profane mans solution) and leave you with a sloppy XP configuration.
    If you are comfortable editing the registry, you can search and remove the reference from where remove it using a popular third-party tool called Autoruns.
    Before making any changes to your registry by hand or with third-party tools, don't forget to first make a backup of the registry. Here is a link to a popular registry backup tool:
    Autoruns does not install anything on your computer.  It will display all startup locations where the reference may be then you can turn it off or remove it completely.  Here is the download link for Autoruns:
    Run Autoruns.exe and wait that he at the end of the filling of the list of entries.
    When the Autoruns is finished scanning your system, it will say "Ready" in the lower left corner.  Autoruns can be a little intimidating to first if you have never seen it before because it displays a lot of information.  You are really interested only a few sections.
    The problem is usually in the usually start startup entries or the system user then click on the connection tab.
    Scroll through the list and look for a boot entry associated files in the error message.
    If you can't find there, look in any tab.
    Right-click on the offending entry and choose Remove.  If you don't see it in Autoruns, you must edit the registry and remove the item from your startup folder it.  Autoruns displays the same information, however.
    Given that you had or have an infection, followed with this:
    Perform scans for malware first, then correct any problems:
    Download, install, update and do a full scan with these free malware detection programs:
    Malwarebytes (MMFA): http://malwarebytes.org/
    SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
    They can be uninstalled later if you wish.
    Restart your computer and solve the outstanding issues.

    Hello Daniel,.

    The drivers that we post do not pay attention to the flavor of Windows 7 you are using.

    They work in all versions (home premium, professional, ultimate).

    Video drivers you are looking for are in the 7 64 Windows section you mentioned.

  • Newbe to epub creation... itunes book oven will not accept encrypted files from InDesign 2014... cant find them and which fonts can use one without this problem?

    Newbe to epub creation... itunes book oven will not accept encrypted files... cant find them and which fonts can use one without this problem?

    The book oven does not accept the embedded fonts that are encrypted, even if the encryption is by the IDPF specifications.

    InDesign will not incorporate fonts unencrypted by respect for the rights of the provider of the police.

    There is no work around as I know, at least with regard to preview what will look like the fonts. If you choose not to embed the fonts then the oven should work, but then you won't be able to see what the fonts look like, no?

    What is the team of InDesign epub is simply side load the epub via dropbox or by e-mail. Two of these routes allow you to choose "open with...". "and iBooks will be one of the choices.

    Apple knows about it. I suggest that you remember that, as a customer, you are not satisfied with this behavior and asks that they go back on their decision.

    I have a sequence that contains an 'IF' statement based on a variable FileGlobal. Is there a way to know where the variable is set / used? Perhaps a watch of some type?

    Thank you

    Hi jvh,.

    Try to Edit-find/replace (STRG-F) and search for when your variable everything serves the SequenceFile.

    I'm sure that you will find the place where it is set.

  • CNV cannot find variable on network

    I start my exploration of the network (NVC) with examples of variables.  Excellent examples.

    Using the project of polling stations, I have the program running on a PC writer.  On another PC, I have the player running program.  I modified slightly so that the path of the network would be selectable by using the sample browser project.

    The drive cannot find the variable network writer.  The browser popup (where the player is running) is the PC that hosts the writer program.  So it's good, in the sense that it checks the two computers are on the same network and subnet.

    But in the browser, the tree is not all associated network variables.  This seems to be a simple problem, but I can't find.

    Also, if I run the application Reader on the same computer that hosts the application to the writer, this popup browser detects the attached network variable.  So, I know that on the same PC, writer and reader work.  Just not on my network (which is kinda the whole point!)

    Here you will find two documents that I have found useful when configuring the network variable scenario:

  • Firefox has completely disappeared from my Apple PC - cant find anywhere - whats happened?

    I have a laptop Mac OS x 10.6.8 running version. Firefox has been installed more than two years ago and has been used exclusively for Internet access, browsing through Telstra wireless cable. Yesterday, I noticed that he had moved his position on the dashboard. I thought that it was strange that this happens without warning at the same time. Today, he is gone entirely from the dashboard. I can find no trace of it in the Applications and indeed, any where even in the trash. It has apparently been deleted somehow without my knowledge or permission. Other applications on the dashboard are still in close and seem to work OK. Can you advise action that there are several attached bookmarks that are very important to me

    Thank you

    Ray Daltrey

    Hi Ray,

    Sorry for the confusion previously. Let me see if I can help solve your problem.

    Have you tried to save the icon to your Dock to see if the icon sticks here? Open Firefox from the Applications once it is visible in the folder, then try to control-click the icon while it is open in your Dock, and then choose Options > keep in Dock.

    Let me know if this is useful, and if we don't need information on what is happening.

  • LaserJet4: HP LaserJet 4-cant find W7 driver (32)

    Cannot find the driver for Windows 7 (32 bit) for LaserJet4.  A forum thread indicated that it is provided in the list of printers W7 but not on my machine.  Impossible to find in the HP download site support because they say that it is loaded with the computer.  I clicked on Windows Update in the Intall printer dialog box and no change in the list.   I don't see HP LaserJet 4, do you think? Where can I find a driver?  Thank you

    Hello:

    I don't see any messages on your part on this thread because I answered.

    I see the driver in the Microsoft file, I recommended, and you will need to install the printer using the method of "Have Disk" using the Add Printer Wizard, because as you say there is no executable file in there.

    Here's what you should do... download than laserjet 4 file again if you managed to get rid of it.

    Then install this free utility for files.  The first file of the page is for W7 32 bit.

    http://www.7-zip.org/

    After you install 7 - zip, open the folder of the downloaded driver and do a right-click on the X 86 - all... file and select 7 - zip from the list of items.

    Have 7-zip extract of: and let it extract the files to a folder (I leave extract the file name).

    Once you have done this, you will see all the driver files in this folder of extraction.

    This configuration prnhp001 information file is the file that you want to browse to when you use the add a Printer Wizard, select HP printers and select the printer laserjet 4 in the list, and then select the disk and navigate to this file and install the drivers.
