Get content of cell from QTableView

imene

@SGaist said in Get content of cell from QTableView:

ui->tableView->model()->index(index.row(),0).data().toInt();

It doesn't work for me it returns "member reference base char'(const char,int) throw()' is not a structure or union":

@imene
You are in the middle of MainWindow constructor. On the line you show, in the index.row() expression what is the index variable, where is it declared, what is its type?

The point of this question is to get the content of a QTableView cell, where the cell you want is in the model at QModelIndex index.

Hi, I've tried the same (almost, because in python), but I gain error: name 'index' is not defined

@Karoluss96 Please post the code.
Did you define the "index" member variable?

Karoluss96

No, but It is noe build-in function? like here: https://stackoverflow.com/questions/37035756/how-to-select-multiple-rows-in-qtableview-using-selectionmodel

jsulm

@Karoluss96 If you read this thread, especially what @JonB asked you will see that it is unclear what index is in the code posted. Sinse it is not my code I also don't know.

Karoluss96

I put tableView.currentIndex() here, that take the number of index for data, which work correct, but later .data() says: ' 'int' object has no attribute 'data''

jsulm

@Karoluss96 Can you please post the code?

Do you expect people to say anything useful about this when you show no code?

Karoluss96

My plan is to get data from whole table and separate it between rows to make sql question (Insert Into those who are new added)
now (after cutting of .toInt() ) looks that:

data= self.dlg.tableView_3.model().index(self.dlg.tableView_3.currentIndex().row(),0)
        dt=data.data()
        print (dt)

Karoluss96

It take only the first record from selected row, wheras I need all data from selected row, which later I want to put (separatly one-by-one) to a sql question

Careful with words, you mean column not record. So look at your 0 argument which only fetches the data for column 0, and write code to pick up all the columns in the row if that is what you want....

Karoluss96

Maybe some loop will be good?

JonB

@Karoluss96 I would think that would indeed be a good idea if you want to get the content of each column :)

Karoluss96

Now I have:

data= self.dlg.tableView_3.model().index(self.dlg.tableView_3.selectionModel().currentIndex().row(),0)
dane=data.data()
       for i in data:
           data=self.model4.selectIndex(i)
           print (data)

but it get error: 'QModelIndex' object is not iterable

JonB

@Karoluss96
This is wrong. Your data variable is a single data index item, you can't go for i in data. Please look at the documentation for correct usage of QVariant QAbstractItemModel::data(const QModelIndex &index, int role = Qt::DisplayRole) const or QVariant QModelIndex::data(int role = Qt::DisplayRole) const

Karoluss96

hmm, so maybe the the whole row at begin in loop?

JonB

@Karoluss96
I really should not have to tell you this! If you want to allow for picking all the columns in a row even if just one cell is selected (so you can't only look at selected cells) you will want something like:

row = self.dlg.tableView_3.selectionModel().currentIndex().row()
model = self.dlg.tableView_3.model()
for col in range(model.columnCount()):
    print(model.index(row, col).data())
# Or I think you can do this in Python:
rowData = [ model.index(row, col).data() for col in range(model.columnCount()) ]
print(rowData)

self.dlg.tableView_3.selectionModel().currentIndex().row()

Well, It works, but I need to separate it to put every attribute to INSER INTO sql query.

Thnaks for help!

@Karoluss96
I don't know why you quote the first line of this code, but anyway.

Well, It works, but I need to separate it to put every attribute to INSER INTO sql query.

And what is the problem with that? Assuming

rowData = [ model.index(row, col).data() for col in range(model.columnCount()) ]

works in Python you have rowData containing all the values you need for your SQL statement.
