How to save the edited data in QListwidgetitem using a push button

[Choti]

Hello Everyone,

I am having a problem in saving the data obtained from Qlistwidgetitem. I am using a QListWidgetItem, where I am getting some data from the server on the window. Now I am able to edit the data whivch I got from the server. In the next step Ishould be able to save the data I have edited and send back to the server.

Please can anyone help me with this situation.

Thank you in advance

It is hard to tell what part of the task you need help with?

Do you have a slot connected to the button?
Does that slot have access to the QListWidget?

Thank you for your reply. Yes I have a slot connected to the button. As shown in the picture that was the data I recieved from the server. Now I am supposed to edit the "values" and save them and send back using the pushbutton SEND. I am able to edit the values but I am confused how to save the edited data.

I assume this is about the second list and the values are all integers?

You can simply iterate over the list using QListWidget::count() and QListWidget::item() and for each item e.g. get the text with QListWidgetItem::text() and calling QString::toInt() to convert to integer.

The second list is a group of strings. Among all the values I am supposed to edit only two values which are non zero. Then I should save it and send back to the server.


void MainWindow:n_pushButton_clicked()
{
QListWidgetItem *list2 = ui->valueWidget->currentItem();

list2->setFlags(list2->flags()|Qt :: ItemIsEditable);

}


As shown in the code list2 is getting data from the server .

So what actually do you need help with?

This code makes the current item editable.

Now I want to save the edited value .

Well, get the value from the item (see comment #4) and save it.
