QWidget with a return value

[qlands]

That depends. You can call QDialog with exec() so it appears as modal (the user cannot interact with other windows (including the parent) until it close the dialog). If the user can interact with the parent while the window with edits is on the screen then you can use a QDialog but calling show() or a QWidget.

OK, if I would use QDialog with the exec function. How can I return the values from the QLineEdits to the parent widget?

ok You create a C++ class based on QDialog. Using QT designer for example. Say you called it myDialogWithEdits.

This class has in its ui the edits. Because the ui is private you need to create a public function to get the value from the edits. Lets call it getValueOfEditOne().

in the .h

public:
    QString getValueOfEditOne();

public:
    QString getValueOfEditOne();

To copy to clipboard, switch view to plain text mode 

in the .cpp

myDialogWithEdits::getValueOfEditOne()
{
return ui->edit1->text();
{

myDialogWithEdits::getValueOfEditOne()
{
return ui->edit1->text();
{

To copy to clipboard, switch view to plain text mode 

The in the parent you do:

QDialog myDialogWithEdits;
    myDialogWithEdits.exec(); //This will call modal and wait until its closes
 
//This will be executed after it closes
ui->edit1->setText(myDialogWithEdits.getValueOfEditOne());

QDialog myDialogWithEdits;
    myDialogWithEdits.exec(); //This will call modal and wait until its closes
    
//This will be executed after it closes
ui->edit1->setText(myDialogWithEdits.getValueOfEditOne());
