[SOLVED]How to get the value of a row in TableView using QML?

CoderJeff

I know the property currentRow, but I want to get the value instead of the index.

Is there any method?

@CoderJeff Since you already have the index or row number get the value from model. Ofcourse the method depends on which model type you are using.

Yes, I tried to do it like what you said. But the model is from C++:

TableView {
id: tableView
......
model: myModelCpp.model()
......
}

The type of myModelCpp is MySqlModel, which inherits QSqlTableModel.

Do I need to add a get function in C++ code?

p3c0

@CoderJeff Yes add a Q_INVOKABLE get (or any other suitable name) function.

I feel it is another unreasonable design about QML.

I think whatever and wherever the model is, once it is in QML, it should be converted to a kind of unified type like List or something else, and QML provides an unified interface that is convenient to call.

In addition, I tried to add the same code in ComboBox:

ComboBox {
......
model: myModelCpp.model()
......
}

But it did not work, showing that the model is undefined.

Actually, either TableView or ComboBox, for us, their model are both a kind of data set, which should be used everywhere. Otherwise, we need to think about too much.

@CoderJeff I suspect you are definitely doing something wrong. Personally I have been using C++ models and never faced any major problems. Same C++ model in my case works perfectly with ListView and ComboBox. In case of ComboBox you have to use textRole to populate but it is not related to model undefined.
Eg:

ComboBox {
    model: myModel
    textRole: 'title'
}

@p3c0
You are right. My ComboBox code works according to your method.

QML is like an unearth buried treasure. As a beginner, I have a very long way to explore it.

Thank you p3c0.

@CoderJeff You're Welcome :)
I would suggest you to start from QML basics to make the roots strong.
