QVariantList in ArrayDataModel
Hello
I have a little problem with getting the information of my ArrayDataModel in C++.
My ArrayDataModel contains items that are QVariantMaps, each of which contains several QStrings.
Here's how I fill this ArrayDataModel:
QVariantMap map;map.insert("name", name);
map.insert("path", path);
map.insert("completePath", FileToOpen);
model->append(map)
Not in another function, I want to go back 3. element in the QVariantMap, means the QString FileToOpen.
How can I do?
That's what I got so far:
for (int i = 0; i < model->size(); i++) {
model->value(i);
}
With this, I get that:
QVariant(QVariantMap, QMap(("completePath", QVariant(QString, "completePath") ) ( "name" , QVariant(QString, "filepath") ) ( "path" , QVariant(QString, "filepath") ) ) )
But how do I get as a string of this QVariantMap?
I think it should be pretty easy, but I'm stuck. Can someone help me out here?
In the ArrayDataModel docs (https://developer.blackberry.com/native/reference/cascades/bb__cascades__arraydatamodel.html#functio... I found that with the 'data' function, I get the question but I don't know how to use it here.
Get you with card-> value (
i.e. s QVariant = map-> value("name")

How to manage updates of data in ArrayDataModel
Hello
I load some data from a JSON file in a QVariantList which is then added to an ArrayDataModel that allows to display the data in a ListView. It all works very well. Now, I want to update certain values of a ListViewItem and want to propagate these changes to the ArrayDataModel-> QVariantList-> JSON file. How I would handle this? Should I update the DataModel, ListView or even the QVariantList? Loading and display of data in a ListView are very well documented, but I can't find information on reverse litle?
Any help will be greatly appreciated!
You can access the dataModel of ListView items so it is possible to directly manipulate.
Outside the ListView join dataModel signals such as
void itemAdded (QVariantList indexPath) void itemUpdated (QVariantList indexPath) void itemRemoved (QVariantList indexPath) void itemsChanged (bb::cascades::DataModelChangeType::Type eChangeType=bb::cascades::DataModelChangeType::Init, QSharedPointer< bb::cascades::DataModel::IndexMapper > indexMapper=QSharedPointer< bb::cascades::DataModel::IndexMapper >(0))
You'll probably have to subscribe to each of them as you know what changes you make to the dataModel. For example, if you only update the elements subscribe to itemUpdated etc..
In Manager signals, extract the dataModel changes and save them to the disc.
PS Don't forget to subscribe to the changes that the dataModel is initially populated.

solution: bps netstatus_interface_list_t as QVariantList
I was looking for an easy way to know the name of the interface for WIFI, cell PHONE...
These names are different for Z10, Z30, Q10,... you can't find names
First aid, I found was Cascades Sample App "MyDevice".
Congratulations to Martin Woolley @mdwrim providing this app to wander on Github
Now I could get the names of WIFI connections, but lacked a way to get the names for cell PHONES
discussed with @mdwrim on twitter and got to come an interface more names for cell PHONES, but this could be broken easy to new devices.
next congratulations to @dkonigs who joined the discussion on twitter mentioning Netstatus API to inspect the Interface Types
OK - I wanted to use the netstatus and discovered that I have a loop through a list of interfaces netstatus and tried this code.
thought it would be easy because I already used Netstatus events to know if the user is on WIFI, cell PHONE etc.
But I have to give up - as a former Developer Java and C++ now / Qt developer such things bps C does not for me.
next Bravo to strobejb help with the code in this thread here. Based on his code I solved it and now it's easy to know all the Netstatus Interfaces.
Here is a method that you give bps bps netstatus_interface_list_t as QVariantList, so you can use for data models, storing as JSON or almost.
QVariantList YourClass::netStatusInterfaceList() { QVariantList interfaceList; netstatus_interface_list_t iflist; netstatus_get_interfaces(&iflist); for (int i = 0; i < iflist.num_interfaces; i++) { netstatus_interface_details_t *details = 0; netstatus_get_interface_details(iflist.interfaces[i], &details); if (details) { QVariantMap interfaceDetailsMap; const char *name = netstatus_interface_get_name(details); qDebug() << "DETAILS FOR Interface: " << name; interfaceDetailsMap.insert("name", name); netstatus_interface_type_t type = netstatus_interface_get_type( details); bool connected = netstatus_interface_is_connected(details); interfaceDetailsMap.insert("connected", connected); bool up = netstatus_interface_is_up(details); interfaceDetailsMap.insert("up", up); interfaceDetailsMap.insert("hasType", type ? "true" : "false"); if (type) { interfaceDetailsMap.insert("type", type); switch (type) { case NETSTATUS_INTERFACE_TYPE_WIRED: interfaceDetailsMap.insert("typeName", "WIRED"); break; case NETSTATUS_INTERFACE_TYPE_WIFI: interfaceDetailsMap.insert("typeName", "WIFI"); break; case NETSTATUS_INTERFACE_TYPE_VPN: interfaceDetailsMap.insert("typeName", "VPN"); break; case NETSTATUS_INTERFACE_TYPE_BB: interfaceDetailsMap.insert("typeName", "BB"); break; case NETSTATUS_INTERFACE_TYPE_UNKNOWN: interfaceDetailsMap.insert("typeName", "UNKNOWN"); break; case NETSTATUS_INTERFACE_TYPE_USB:; interfaceDetailsMap.insert("typeName", "USB"); break; case NETSTATUS_INTERFACE_TYPE_BLUETOOTH_DUN: interfaceDetailsMap.insert("typeName", "BLUETOOTH_DUN"); break; case NETSTATUS_INTERFACE_TYPE_CELLULAR: interfaceDetailsMap.insert("typeName", "CELLULAR"); break; case NETSTATUS_INTERFACE_TYPE_P2P: interfaceDetailsMap.insert("typeName", "P2P"); break; default: interfaceDetailsMap.insert("typeName", "????"); break; } } if (connected) { // enumerate the ip addresses for this interface int numip = netstatus_interface_get_num_ip_addresses(details); QVariantList ipAddressList; for (int j = 0; j < numip; j++) { QVariantMap ipAddressMap; const char *ip = netstatus_interface_get_ip_address(details, j); const char *nm = netstatus_interface_get_ip_address_netmask( details, j); ipAddressMap.insert("ipAddress", ip); ipAddressMap.insert("netmask", nm); ipAddressList.append(ipAddressMap); } interfaceDetailsMap.insert("ipAddresses", ipAddressList); // enumerate gateways for this interface int numgw = netstatus_interface_get_num_ip_gateways(details); QVariantList ipGatewayList; for (int j = 0; j < numgw; j++) { QVariantMap ipGatewayMap; const char *ip = netstatus_interface_get_ip_gateway(details, j); ipGatewayMap.insert("gatewayIp",ip); ipGatewayList.append(ipGatewayMap); } interfaceDetailsMap.insert("ipGateways",ipGatewayList); } interfaceList.append(interfaceDetailsMap); } // end if details // FREE Memory netstatus_free_interface_details(&details); } // FREE Memory netstatus_free_interfaces(&iflist); qDebug() << "List of Netstatus Interfaces: " << interfaceList.size(); return interfaceList; }Thanks again to all the forum here and twitter. It's really nice to work with this great community

Try the following steps:
(1) remove #include
.h file (2) in the .h file before - declare the class as follows:
namespace bb { namespace cascades { class ArrayDataModel; } }3)
Use full names in the header files:private: bb::cascades::ArrayDataModel *model;
(4) in the C++ file adds:

QML QVariantList QString Converter?
Hey all
I'm relatively new to programming of BB. I have some experience in Android and Windows Phone, but I think that BB10 will kick a lof of * beep *!
I did a bit of programming for my application and I use a Web service to download the json from the server data. Now, I have programmed a view master / detail with qml, when clicking on an item in the list, I get the details of this item.
But the article also has QVariantLists because it is a data table. For example, in my json file, I have the language of property: ['Dutch', 'English', 'French'].
Now, I want to show these multiple languages in my detailpage. Is it possible to write a converter or something like that? Or should I do the treatment before you add data to my datamodel?
Thanks in advance!
QVariant-s work just like the javascript in QML tables.
If you know how to access this QML QVariantList, you can also iterate through it the addition of all the members of a chain.var s = ""; for (var i = 0; i < myList.length; i++) { console.log(myList[i]); if (i != 0) s += ", "; s += myList[i]; } -
Fill out the strings of QSettings to ArrayDataModel
Hello
I want to read several QSettings strings and then fill in an ArrayDataModel.
So with this code, I've saved several channels in QSettings:
void ApplicationUI::saveDataInQSettings(QList
filepath) { QSettings settings; settings.beginWriteArray("filepaths"); for (int i = 0; i < filepath.size(); ++i) { settings.setArrayIndex(i); settings.setValue("filepath", filepath.at(i)); } settings.endArray(); } Now, I want to recover the QSettings channels as follows. I have a C++ function that fills the QSettings strings in a QList
: QList
ApplicationUI::fillQSettingsInQList() { QList filepaths; QSettings settings; int size = settings.beginReadArray("filepaths"); for (int i = 0; i < size; ++i) { settings.setArrayIndex(i); QString filepath; filepath = settings.value("filepath").toString(); filepaths.append(filepath); } settings.endArray(); return filepaths; } In my main.qml, I have a NavigationPane containing a container in which the ArrayDataModel is displayed.
I put the fillQSettingsInQList () - method in onCreationCompleted then I have the TI in QML when the application is open:
[...]NavigationPane { id: navigationPane onCreationCompleted: { Qt.app = app; var filepaths = app.fillQSettingsInQList(); }But how can I now fill this strings in the ArrayDataModel?
Thanks for the replies. I have not used the track with a list of the QStrings. It is now much simpler.
I saved the ArrayDataModel strings in the QSettings in this way. First of all, I saved the channels how I'll put in the QSettings and different channels:
void ApplicationUI::saveDataModelInQSettings(bb::cascades::ArrayDataModel* model) { QSettings settings; settings.setValue("size", model->size()); for (int i = 0; i < model->size(); i++) { QVariantMap map = model->value(i).toMap(); settings.setValue("string_" + QString::number(i), map.value("string")); } }And completely action to get the information back to the ArrayDataModel of the QSettings:
void ApplicationUI::fillQSettingsInDataModel(bb::cascades::ArrayDataModel* model) { QSettings settings; int size = settings.value("size", 0).toInt(); for (int i = 0; i < size; i++) { QString filepath = settings.value("string_" + QString::number(i), "String not found").toString(); model->append(filepath); } } -
I use under coding in my application, but it does not return even in the consol too. If I remove
If (text [i] .length () > 100)
continue;then back to work properly and if I add consol.log (text [i] .length ()) and then not too much work back the two for another production and in the consol qml
But I want to delete line which has more that 100 length what mistake I do please help me
ApplicationUI.cpp
QVariantList Content1.
issue of textFileRead (content1);
Main.QML
onCreationCompleted: {}
_APP.textFileRead.connect (onTextFileRead)
}
function onTextFileRead (content1) {}
var text = content1;
for (var i in the text) {}
If (text [i] .length () > 100)
continue;
mytextarea. Text = mytextarea.text + text [i]
}in JavaScript, you must use .length and not. length()

View the QVariantList given on the label?
Hi Experts,
I've stored some constant string in QVariantList in C++ file. And I want to print all the stored string in QVariantList on QML label.
Please suggest me how do.
Thank you
the first step is to present the data to the qml. This should cover you there:
https://developer.BlackBerry.com/native/documentation/Cascades/dev/integrating_cpp_qml/qml, you can use the qvariantlist as an array. for example:
var data = _app.getData(); for (var i = 0; i < data .length; i ++) { var label = labelDefinition.createObject(); label.text = data[i].value labelContainer.add(label)} -
QVariantList gives QString int not
Hey there
You have a problem with my QVariantList.
When I do
QSettings settings(author, appName); if(settings.value("days").isNull()) { QVariantList list; for(int i = 1; i < 6; i++) list.append(i); settings.setValue("days", list); } qDebug() << "initialize: "<< settings.value("days").toList();He said: initialize: (QVariant (QString, '1'), QVariant (QString, '2'),...)
But I do of the economies of the int, am I right?
I need to record the first 5 days to a week.
The user can select them in a dialog box. The first 5 days are the default.
When today is in those selected, my headless service did something
Are you sure?
By
if( settings.value("days").toList().contains( QDate::currentDate().dayOfWeek() ) )I check, if today is one of the days of qsettings.
Before I changed some of my Code it worked that way.
Wired-. -.
I solved it by using QString::number(QDate::currentDate().dayOfWeek())
I personally would say that it is a workaround
but in any case, thank you

Modification of the ArrayDataModel starting from C++
Hi, I have a ListView and an ArrayDataModel which is created/initialized in QML. I want to change(add, delete, etc.) the ArrayDataModel c ++.
How do I get there? Anyone kind enough to provide a code example? Thank you..
Container { id: mainContainer ListView { id: listView layout: StackListLayout {} dataModel: ArrayDataModel { id: listArrayDataModel } ......... } }Hello
There are two different approaches to C++:
(1) dataModel looking at C++:
Get a pointer to ListView using findChild. Get its data model using the dataModel() function. Mount this dataModel to store in a variable member ArrayDataModel * then use its methods to add items.(2) pass the C++ of QML class model:
Declare Q_INVOKABLE function in C++ which takes QObject * dataModel as its argument. Export an instance of the class where the function is declared to QML. In QML in onCreationComplete call this function and pass listView.dataModel. In the implementation of the function using qobject_cast(arg) to mount the argument of the ArrayDataModel, verify that the casting was successful and then store the result in a member variable. If you need assistance implementation of Scripture above please approach you have chosen, and I will explain more about it.

How to extract the value of QVariantlist
Hello
I was trying to understand quoteapp example to implement the sqldata in my application. In this example, they are passing all qvariantlist in groupdatamodel and use it in listview. But I don't want to use listview and want to access the value of a particular column in a table on a page. Anyone can guide me please how?
I'll try to explain what I did to understand how it works. If you have QVarint or QVariantList, right? So now, print it in console with qDebug().
You will see something like this.
QVariant(QVariantMap, QMap(("StationButton", QVariant(QString, "") ) ( "StationButtonSelected" , QVariant(QString, "") ) ( "StationIcon" , QVariant(QString, "0332.jpg") ) ( "StationName" , QVariant(QString, "JD Inside") ) ( "StationStreamURL" , QVariant(QVariantMap, QMap((".data", QVariant(QString, "http://www.panel-streaming.com/tunein.php/jdinside/playlist.pls") ) ( "type" , QVariant(QString, "pls") ) ) ) ) ( "StationURL" , QVariant(QString, "http://www.jdinside.com/") ) ) )So now if I would get Station stream URL type I need to do the following
QString currType = data.valueQVariantMap>.value("__StationStreamURL__").value ()QVariantMap> ()QString.value("t__ype__").value > ();
As you can see the first structure is QVariantMap, so we use data.velue
() to get it. Then is StationStreamUrl, as QVariantMap and we can get type and convert it to QString. It's something like cabbage, where you need to remove all the layers. It will be useful. If not give me what structure you have and I'll try to help you.
Thank you.

How to get items of the multi ArrayDataModel element
Hello
When I add items to an ArrayDataModel like that
// Main.qmlvar data = {"name": filename, "path": filepath}theDataModel.append(data);How can I get items once again? When I fill out a single item of the data model I can use the value() method
theDataModel.value(i)
This gives the value added to the i - th position. But now I have items at each position in the data model. How can I get each item? When I use again theDataModel.value (i) I get '[object Object]' as output.
Your output [object Object] is ok as is JSON object. To access name or path you need this
theDataModel.value(i).name //print name value theDataModel.value(i).path //print path value
Use the method of data instead of the value of your

2 - is a way to cross the QVariantList and printed content of its elements?
PS that the temp is initialized correctly, I managed to fill a ListView to use it later.
Hello
1. Please check the "Known Limitations" section in the SDK release notes software, it contains information about the configuration of the newspapers:
https://developer.BlackBerry.com/Cascades/download/releasenotes/
2. the code is correct. Another way to browse:
foreach (QVariant v, temp) { qDebug() << "String Value: " << v.toString() << "\n"; }You can also add the new line to serve the line otherwise last exit may be lost on the crash of the application.
Foreach also makes a copy of the list before to iterate. QT performs lazy copy (copy-on-write) data, so it is not very expensive and you can edit safely from the container during the iteration.
