Update of GroupDataModel list item for the lazy loading

I have a ListView of StandardListCompoenet that is created with a GroupDataModel in C++.

Mail, click on a button, I have to change the text content of a row in the ListView based on the number of line typed by the user in a text box.

Goes according to the GroupDataModel API - updateItem(indexPath,QVariantMap), it can be done, I am able to build to get the row.

There is a ListView (QVariantList) trigger method - which refers to the row of the item selected by the user.

Since, in my code, I don't have the numero_index of the line of the user, is there a way I can build the "row" to "updateItem" of my code itself.

Or should there be any other strategy that should be chosen instead?

Found the solution,

the key is to start finding the QVariantList (s) of the dataModel-> first()

and then to reach the destination by comparing the values of data.

Then, it would take to build a data path it would be identical to that received by trigger (QVariantList)

    Hi all

    I have a MBP of 2009 end. I updated the material to 8 GB of ram with an SSD of 240gig. I want to run the new OSX, but is not on the list approved for the update. Anyone know why?

    It is a decision that was made by Apple.  El Capitan is the newest OSX that will support a 2009 MBP.

    This is not uncommon.  My 2006 MBP came with Tiger, but is limited to OSX Snow Leopard.

    Old hardware ends up by becoming obsolete with newer technology.

  • Error ERR-1002 unable to find item for the 'ID' element ID in the application

    Hello world

    I'm new to APEX and I came across this error for the first time. I have a page with a classic report in it, and I want to create a link to one of the columns in the report (column ID) to another page with a classic report in it. So when I click on, say, ID 118, I want to be sent to another page and don't see ID 118 information.
    After you create the link in the column, I get the error message when I run the application:

    Error ERR-1002 unable to find item for the 'ID' element ID in the application

    I tried to create a link from one report to the other before and it worked fine.

    Thank you!

    P.S. I use APEX 3.2

    Then you must create an item called ID on your page 2 (hidden make) and the link will pass the value of the ID of the line picked up on this hidden item. Now in page 2 make your report filter query on id = P2_ID or another name that you use...

    Hope this helps,

    Hello
    I worked with apex 4.2 and I create normal classic report with list (named loved) select a column, now I want to update the table when the user changes the list with the new value, I can't create a dynamic action to do this, I create checkbox with the primary key and the loop for check point to update the table but I can not get the value of the list item. and for more speed, the user want to do it when changing the value from the list.

    My question
    1. how to do it in javascript and get the value of the list item and update the table with the new value
    2. do I have to use the API to create the list item so I can get the value of the report item or what.

  • like firefox updates, it takes more time for the program to load, using win 7 it takes 17secs toopen window

    One of the reasons for the use of firefox is its ability to be in place and ready to use quickly (I was one of the first users.) Now, Google and dare say int explore seem to have the advantage

    One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

    Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

    See:

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).

    Create a new profile as a test to see if your profile is the source of the problems.

    See "basic troubleshooting: a new profile:

    There may be extensions and plugins installed by default in a new profile, so check that in "tools > Modules > Extensions & Plugins" in case there are still problems.

    If this new profile works then you can transfer files from the old profile to the new profile, but make sure not to copy corrupted files.

  • Frequency minimum step length and duration list minimum for the frequency lists in the generator of signals from NI 5406

    Hello

    We need power RF amplifier with a function generator to create plasma in an ion source. The signal pulse duration must be 1ms long, repeated twice per second.

    Today, we work in the following way: we spend the RF with f0 (aprox 1,995 MHz) frequency. After 20, we send a trigger signal passing frequency f1 (aprox 2.005 MHz).  We keep this frequency for the rest of the pulse.  However, the plasma that we generate is not 'constant' or stable during the whole impulse. If we smoothly change the frequency during the pulse we could improve.

    We would like to do: use the frequency sweep: rather than use this frequency hopping, we would like to move smoothly f0 f1 (frequency scanning). Then F1 to f2.

    As we have a PXI for data analysis, we believe using the arbitrary function generator of NOR: 5406 of NEITHER allowing the frequency sweep. However, in the book loads, it is not very clear, and I have a few questions:

    -We can create a "list of frequencies. In the site OR below, it shows that the "minimum of Step' is 1.28us, which would be ok for us (I understand that the"minimum duration of Step"is the minimum time between 2 frequencies). However, the manual of the device "NI PXI/PCI-5402/5406 specifications" said the frequency list has a time step of 1 ms to 21s. What is the good?

    -It is also said that the "duration of minimum list" is 1 s. For us, need us a shorter list that 0.5 seconds (we need to repeat the same pulse twice per second.). Is it possible to do what we want?

    -At the end of the day, we would like to implement a control loop which modifies the list of frequencies in real-time.

    http://zone.NI.com/reference/en-XX/help/370524L-01/nisignal_generators_help/features_by_device_smc/

    Thanks for your help.
    Best regards
    Jose.

    Hi Jose,

    You're right about the inconsistencies of the documentation. The minimum step was of 1 ms, but was changed to 1.28 µs to driver version 2.6. The help document has been modified to reflect that, but the specifications were not. I'll make sure that attaches.

    The length of the minimum list is not listed in the book loads, and the latest version of the help the signal generators OR (driver version 2.9) lists the minimum list than the 1 step length. Aid has changed to the driver version 2.6.1 to clarify that the 1s meant 1 step. I've attached a screenshot of the help of the most recent.

    There is an example that is installed with the NOR-FGEN driver called "Fgen Sweep Generator.vi". I would recommend from this for your application.

    I hope that some of the inconsistencies in our documentation brightened. Please let us know if you have any other questions.

  • Choose switch user/group in a line item for the automatic creation of a BP

    Hi all

    I created two business with workflow process. When I create a topic with the first BP, he auto-créer an account of the second BP. But I have to open the folder newly created to push into the workflow (and choose the assignee)

    Is there a way directly choose the assignee to the line item and bypass this step?

    Thank you in advance.

    Thomas

    Hi Thomas, take a look at the controls of the project base SKU BPs (minutes and Actions items specifically). MM topics auto-crée records of HAVE and is configured to support your use case I think... It is using a combination of "previously assigned" on the approval of follow-up action step (assignees = "all users of the project") and also the function "filter assignee" to filter the list of "all the users of the project" down to 1 assignee (based on the value OF 'Login username', i.e. that you have added to the online meeting item minutes that generated automatically during the recording of the AI was created.)

    We have created a few items from the selection list in the Apex and ask users to make changes to the border.
