Convert std::string to QLineEdit

gshannon154

Hi all,

So I have a situation...

The following code allows me to set the text in a QLineEdit called cores using a map called parameterMap:

"advancedsettings->getUi()->cores->setText(QString::fromStdString(parameterMap["cores"]));"

I have a list called allParameters, the entries of which are identical to the keys of parameterMap and the QLineEdit's in advancedsettings. I would like to iterate over allParameters to change the text in every QLineEdit in advancedsettings like so:

"for(list<string>::iterator it = allParameters.begin(); it != allParameters.end(); ++it){
advancedsettings->getUi()->*it->setText(QString::fromStdString(parameterMap[*it]));
}"

However, the above code produces:
error: 'struct std::basic_string<char, std::char_traits<char>, std::allocator<char> >' has no member named 'setText'

and:

"string myString = "cores";
advancedsettings->getUi()->myString->setText(QString::fromStdString(parameterMap[myString]));
"

results in:
'class Ui::AdvancedSettings' has no member named 'myString'

How can I achieve what I want to? I must need to convert a std::string to some QT data type but none of my attempts have worked.

Many thanks,

Hi and welcome to devnet,

lineEdit->setText(QString::fromStdString(yourStdString));

Is the correct form.

Do you have as much QLineEdit in your UI to enter all the strings from your parameterMap ?

Hi!

Many thanks for your help.

To answer your question I have more strings in parameterMap than QLineEdit's in the UI (advancedsettings).

I'd like to iterate through all the QLineEdit's in advancedsettings rather than manually having to do something like:

advancedsettings->getUi()->firstQLineEditInadvancedsettings->setText(QString::fromStdString(myStdString))

advancedsettings->getUi()->secondQLineEditInadvancedsettings->setText(QString::fromStdString(myStdString))

...

advancedsettings->getUi()->lastQLineEditInadvancedsettings->setText(QString::fromStdString(myStdString))

Is there a way I can achieve this?

Man thanks,

SGaist

You can create the QLineEdits dynamically
