Qtableview xml

[AzureSkgale]

im trying to parse data from a qtableview to xml here is my code below:

#
        table = self.the_material_view.the_model
        row = table.item
        input_1 = table.item(row,0).text().strip()
        input_2 = table.item(row,1).text().strip()
        input_3 = table.item(row,2).text().strip()
        filename = QFileDialog.getSaveFileName(self, self.tr('Save File'),
                                                            os.getcwd(), self.tr("xml files (*.xml);; All files(.txt)"))
        file = open(filename[0],"w")
        file.write('<name>{name}</name>\n'.format(name=input_1))
        file.write('<material_type>{material_type}</material_type>\n'.format(material_type=input_2))
        file.write('<density>{density}</density>\n'.format(density=input_3))
        for row in range(3):
            for column in range(3):
                if table.cellWidget(row, column) == True:
                    file.write('<c{row}{col}>{data}</c{row}{col}>\n'.format(row=row + 1, col=column + 1,
                                                                        data=table.item(row, column).text().strip()) + "\n")

#
        table = self.the_material_view.the_model
        row = table.item
        input_1 = table.item(row,0).text().strip()
        input_2 = table.item(row,1).text().strip()
        input_3 = table.item(row,2).text().strip()
        filename = QFileDialog.getSaveFileName(self, self.tr('Save File'),
                                                            os.getcwd(), self.tr("xml files (*.xml);; All files(.txt)"))
        file = open(filename[0],"w")
        file.write('<name>{name}</name>\n'.format(name=input_1))
        file.write('<material_type>{material_type}</material_type>\n'.format(material_type=input_2))
        file.write('<density>{density}</density>\n'.format(density=input_3))
        for row in range(3):
            for column in range(3):
                if table.cellWidget(row, column) == True:
                    file.write('<c{row}{col}>{data}</c{row}{col}>\n'.format(row=row + 1, col=column + 1,
                                                                        data=table.item(row, column).text().strip()) + "\n")

To copy to clipboard, switch view to plain text mode 

i tried using currentIndex function but keep getting an error, the tableview is not callable, the model is based on QtGui.QStandardItemModel()

In line 2, are you assigning "table" to the QTableView or the QStandardItemModel? If it is the view, then why are you referencing something called "the_model"?

In line 3, if "table" really is a reference to the QTableView and not the QStandardItemModel, then QTableView does not have any method named "item". This will probably throw an exception.

But if "table" is really a reference to the QStandardItemModel, then QStandardItemModel::item() returns a reference to a QStandardItem and needs at least a row number argument. item() does not return a row number. You must tell it which row number you want the item from.

So in lines 4-6, it seems that you are treating "table" as a reference to the QStandardItemModel, because you are calling item() with the correct arguments for the QStandardItemModel::item() method.

But now in line 15, your confusion over whether "table" is the view or the model gets further confused, because neither QTableView nor QStandardItemModel have a "cellWidget()" method. QTableWidget does, but you started your post by saying you were using QTableView.

In any case, QTableWidget::cellWidget() returns a QWidget reference, not a Boolean value, and whether it is a valid object reference or not has nothing to do with the text in the cell.

And in your loop over rows and columns starting in line 13, if "row" in lines 4-6 has the value 0, then in the loop for row == 0, you are retrieving exactly the same items as you did for input_1, _2, and _3.


You need to get clear exactly what classes you are using.

the_material_view is a reference to the qtableview, the_model is the model of that tableview, i need to use qtableview and not qtablewidget

[d_stranz]

i need to use qtableview and not qtablewidge

Then I suggest you rename your variables so you don't get confused between view and model, and read the documentation of QTableView, QStandardItemModel, and QStandardItem to learn the appropriate methods for each class.

Your code is almost correct and will run if you figure out your confusion over the different classes and how to use them. It will run, but may not produce the results you expect.
