Table creation with ListView

[Babs]

Hello, i'm developping an API that allows to show received CAN Bus messages by my can driver systec.
I'm using QCanBus. My received messages are stocked on a QStringList and it contains the identifier, the length and the data. My problem is that i can't create a table using ListView. I'm working on qt 5.11 and using Qt quick control 2.
How can i create a table displaying my data with Listview?

How do you separate data in different columns?

I prefer you build your own model on C++ side & expose the model to QML side. Use delegate to format your data. How to expose the model & view in list view ? Refer the GIT

I want to use a ListView . This image shows my QStringList content at one index. The first element represent the identifier of the CAN message,the second the lenght and third the payload of the message. I want to seperate each one of that elemeents in different columns.

Do you need to QML listView or QTableView is enough ? As @VRonin suggested, you can just use the QTableView along with QStandardModel to display it. If you want to display in QML, suggest you to use your own custom model.

@dheerendra I can't use QTableView because i'm working with qt 5.11 and developping mobile apps. In 5.11 version QTableView is only available for Desktop apps.

You are using the QML. You need to write your own model in C++ side to expose the data to qml. Use either ListView or TableView to display the data.

@VRonin Thank you
I'll try to use Tableview with custom model. Can i have an idea of how to seperates my data in identifiers payload and length colums?
The second problems is that i'm returning a List of QCanBusFrame. This type of data can't be displayed easily

@VRonin Last question.
Where should I seperate my data into frames? In main file or in model file?

[VRonin]

It's really up to you.
I would create the QCanBusFrame outside the model and then load it but it's really just a matter of flavour

[Babs]

const QRegularExpression partsRegExp(R"^\s*(\S+)\s+[(\S+)]\s+(.+?)\s*$");
from your link, this line code generate an error in QT. It says: Invalid character ''....................

[VRonin]

old compiler?
You can double all the \ and remove the R at the beginning

@VRonin Thank you.
I seperated my data successfuly
You can mark it resolved
