<![CDATA[[SOLVED] Add QLabel and QLineEdit from formLayout to QHash]]>Hello,

I have a FormLayout, with several rows which have one Label and one QLineEdit created like this:

@
for(int i=0; i<class.count(); i++)
{
lineEdit = new QLineEdit;
label = new QLabel;
label->setText(class->getName(i));
formLayout->addRow(label, lineEdit);
}
@

I want to get the added content on the lineEdit with its label to a QHashTable. I've already tried some things like using textEdited but there I can only get the content of the lineEdit. With other things like editingFinished I cannot even get that.

I'm really stuck so any help would be appreciated!!!

Thanks in advance!

I finally managed to do it but in another way, because the problem I see with your solution (I think) is that I would only get the last label. I did it like this:

@

for(int i=0; i<class.count(); i++)
{
lineEdit = new QLineEdit;
lineEdit->setAccessibleName(class->get->Name(i));
label = new QLabel;
label->setText(class->getName(i));
formLayout->addRow(label, lineEdit);

connect(lineEdit, SIGNAL(textEdited(QString)),
this, SLOT(addHash(QString)));
}
@

And the slot would look like this:

@
void addHash(QString text)
{
QLineEdit edit = qobject_cast<QLineEdit>(sender());
hash.insert(edit->accessibleName(), text);
}
@

The key to it is the sender function which I didnt know it existed.

Thank you!

@connect(lineEdit,SIGNAL(returnPressed()),&w,SLOT(callme()));

void callme(...)
{
QString text = lineEdit.text();

hash.insert(label.text(),text())

}@

This should help you.
