Changing variables of C++ QML UI (json source and sorting keys)

Hello

I have a tabbed two tabbed pane. I want to fill each tab with a dfifferent JSON (list (not XML). I managed to fill the first tab with the first json file... following the example of application stampcollector. All the UI is QML but JSON loading and groupdatamodel of adjustment is done in C++.

1. now I want to fill the tab page of the 2nd with another JSON list. How can I go about it? Create a new class or can I change the JSON source when the 2nd tab fires?

2 just like in the application of stampcollecctor, I use sort keys. I have a few elements of the action in QML, that when you press on, I want that sort of change lists. So let's say that the first action to sort A - Z, the second action Z - A, the third of the population, action action 4th by area. How to access and change the sort key?

3. is there in any case to sort alphabetically in reverse order, from Z - A?

Code I have so far is below... just no idea where to start...

1. you will need to duplicate what you did for the other tab. Check out weatherguesser which has a bunch of tabs and datamodels.

2. order groupdata model page

Try:

countryModel->setSortingKeys())

countryModel-> setsortedascending (false)

                }
            } // end of Page

But then when the page is loaded, is not load or filter by property string idlibro. Becuse the query in the data source is idlibro.

            ]
            onTriggered: {
                if (indexPath.length > 1) {

                }
            }

            attachedObjects: [
                GroupDataModel {
                    id: gdmCapitulos

                },
                DataSource {

                    query: "select ('Capítulo ' || IdCapitulo) as Capitulo, IdVersiculo, Versiculo from CapitulosVers Where IdLibro = " + lblNombre.text + " GROUP BY IdCapitulo ORDER BY IdCapitulo DESC" 
onDataLoaded: {
                        gdmCapitulos.clear();
                        gdmCapitulos.insertList(data);
                    }
                }
            ]

            onCreationCompleted: {
                dtCapitulos.load();

            }

        }
    }
}

HOW CAN I ACHIEVE THIS?

ITS important to say, its fine words is a set a query without params. example (select * from CapitulosVers Where idlibro = 1).

THANKS IN ADVANCE

I did the solution...

in the second .qml, just before closing the page, put this:

 onIdlibroChanged: { dtCapitulos.query = "select ('Capítulo ' || IdCapitulo) as Capitulo, IdCapitulo, IdVersiculo, Versiculo from CapitulosVers Where IdLibro = " + idlibro + " GROUP BY IdCapitulo ORDER BY IdCapitulo DESC" dtCapitulos.load();

 }

 onCreationCompleted: {
                dtCapitulos.load();

            }

How to replace the string "\" on json webservice?

Hello

I have problem with this json

"{\"search_result\":[{\"name\":\"Mall Summarecon\",\"category\":\"BusinessEntity\",\"id\":\"1\"},{\"name\":\"Bamboo Dim Sum\",\"category\":\"BusinessEntity\",\"id\":\"2\"},{\"name\":\"Dimsum Ceker\",\"category\":\"Item\",\"id\":\"1\"}]}"

I want to replace the string "\".

the json are already working on my app via .cpp file

I already add json.replace on my qml

function simpleSearch(response){
        indicator.stop()
        model.clear()
        console.log("Response: "+response)
        var json = JSON.parse(response)
        json = json.replace('\\', ' ') // this is how the way i replace
        if (json == "[]")
            notFound.visible = true

        else
            model.append(json.search_result)
    }

but still does not work

is there a different way to replace it?

Thank you

Change your simpleSearchFinished as follows

....simpleSearchFinished()
{
    QNetworkReply *reply = qobject_cast(sender());
    if (!reply->error()){
        QByteArray response = reply->readAll();
        response.replace("\\", "");
        if (response.startsWith("\"")){
            response.remove(0, 1);
        }
        if (response.endsWith("\"")){
            response.remove(response.length()-1, 1);
        }
        emit simpleSearchDone(response);
    }else{
        const int httpCode = reply->attribute(QNetworkRequest::HttpStatusCodeAttribute).toInt();
        qDebug() << "ErrorCode" << httpCode << endl << \
                "ErrorString" << reply->errorString();
        emit error(httpCode, reply->errorString());
    }
    reply->deleteLater();
    manager->deleteLater();
}

and QML

function simpleSearch(response){
    indicator.stop()
    model.clear()
    var json = JSON.parse(response)
    if (json){ // is VALID/PARSED
        model.append(json.search_result)
    }
}

As I wrote, it is not a good workaround solution. The best is to send VALID JSON string directly from your server. But it works

How to make a page QML figurentsur only the first launch

How to make a qml page appears only on the first time the application is started?

I need to create a tabbed pane and the number of tabs depends on n the input from the user to whom it provides the first launch. How to make this happen?

You can use QSettings to store parameters.

Create two main qmls (mainHasInput.qml and mainHasNoInput.qml). When the user runs your application for the first time, load mainHasNoInput.qml. If the user enters the input values correct, who writes in your QSettings. The next time that the launch of the app, you check if a setting has been stored in your QSettings. If not, show your mainHasNoInput.qml, if yes, see the mainHasInput.qml (which is your main 'normal' screen)

for an example how to use QSettings, see https://developer.blackberry.com/native/sampleapps/ -> 'persistent objects '.

The every thing must have himself installed in the first place. I took my mom (she died in June) and my brother on this PC as users so even if they do not use this PC supports multiple users. Maybe if I deleted as a reboot and additional users it will solve my problems. My updates install OK but I can't run at all system restore. It creates a restoration point OK but when I try to sr back to a restore point before I get the error 0x80073AFC topic of the missing MUI file. Then, when I spear SR it is said that he could not and no files have been changed because of the error 0x8000FFFF error, unspecified catastrophic failure and could not retrieve the file several times when system restore is attempted.
  
  I'm running Windows 7 on a HP Pavilion with browser Firefox 3.6.8 browser Opera 10.60, IE8 and Google Chrome 5.0.375.125 browser browser.
  
  Can you tell me what I try next? Thnks a lot and sayonara for now the guy-Jack McElwee / keimanzero the Scion of the Anime in Brookhaven PA - USA
  
  OK I tried everything and nothing works! Only added beginners are updated browser Opera 10.63; IE9 (Beta); Firefox 3.6.12 and Google Chrome 7.0.517.41 and Java 22. Of course like everyone else in the world, I had to uninstall/enable and disable/download again and reinstall new Adobe Flash 10 and 11 of the shock wave and they keep crashing too! Hello 4 keep screwing browsers and now I get connection network problems. I run Comcast doctor and did everything it said to do, but nothing works. Oh and I added 7-Zip and WinZip also. Likewise, they will not work! Help! Thanks - K & K
keimanzero,

Comcast of Norton Security Suite version is installed? If Yes, who and perhaps malware is most likely to cause questions you have published, in particular the failure of the restoration of the system.
First, configure the system to boot - How to solve a problem by performing a boot in Windows Vista or in Windows 7
NOTE: Start-up mode minimum state all the 3rd party firewalls will be disabled. Open Control Panel > Windows Firewall to make sure that the native firewall of Windows 7 is now on.

Download and Save the update system (or CheckSUR) tool. You will need to download the specific Version of CheckSUR corresponding to the architecture of the system to Windows 7. If you do not know the architecture of the system, and then click the link that says "Click here to show or hide the instructions step by step with images" under method 2: download the update directly system preparation tool from Microsoft Download Center .
Description of the preparation tool system update for Windows Vista for Windows Server 2008, for Windows 7 and for Windows Server 2008 R2

Once the download is complete, close all open programs and browsers. Now, run CheckSUR with the system connected to the internet because it will download the .cab for system files. Reboot once CheckSUR is complete.

Secondly, I suggest that you run the File Checker system while in the same clean boot state.
To run the System File Checker tool, follow these steps:
1. Click Start and type cmd in the field search programs and files .
2. Right click on cmd.exe in the programs of list, and then choose 'run as administrator '.
  If you are prompted for an administrator password or a confirmation, type your password or click on continue.
3. At the command prompt, enter the following line exactly as written including the space between thec and the/and then press ENTER:
  sfc/scannow
When the analysis is complete, test to see if the problems facing the system have been resolved.

If they are not, you will need to contact Norton support for the version of Norton Internet Security Comcast to get help, or just uninstall NIS, run the Norton removal tool (right click Norton_Removal_Tool.exe, choose "Run as Administrator"), reboot and then check to see if the problems are still occurring.

How can error 10, I solve this problem

I've upgraded to windows 7. started having a few problems. returned to windows vista. now, the driver does not start. shows error 10. need help

Hello

Visit this link to solve problems:

Description of errors related to the 10 Code that generates the Device Manager in Windows on the computers http://support.microsoft.com/kb/943104/

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

This is my generic how updates of appropriate driver:

This utility, it is easy see which versions are loaded:

-Free - DriverView utility displays the list of all device drivers currently loaded on your system.
For each driver in the list, additional useful information is displayed: load address of the driver,
Description, version, product name, company that created the driver and more.
http://www.NirSoft.NET/utils/DriverView.html

For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
Control Panel - device - Graphics Manager - note the brand and complete model
your video card - double - tab of the driver - write version information. Now, click on update
Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
Uninstall - REBOOT it will refresh the driver stack.

Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
with their own software and drivers and all other main drivers that you have.

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.

Always check in the Device Manager - drivers tab to be sure the version you actually install
presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
in particular that) so to install a driver - reboot - check that it is installed and repeat as
necessary.

Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
manually by model. Search manually on the sites of the manufacturer drivers - and the manufacturer of the device
sites.

How to install a device driver in Vista Device Manager
http://www.Vistax64.com/tutorials/193584-Device-Manager-install-driver.html

If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
Updates, that leaves about Windows updates but it will not install the drivers that will be generally
older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then
get new manually if you wish.
