Ok so here is what I've got... doubleSpinBox to doubleSpinBox_312. I made them all read only, I only want them the to be edited from within 1 dialog. Ive made one of them clickable through an eventFilter:

Qt Code: 
  1. MainWindow::MainWindow(QWidget *parent) :
  2.     QMainWindow(parent),
  3.     ui(new Ui::MainWindow)
  4. {
  5.     ui->setupUi(this);
  6.     ui->doubleSpinBox->installEventFilter(this);
  7.     QObjectList o_list = ui->doubleSpinBox->children();
  8.     for(int i = 0; i < o_list.length(); i++)
  9.     {
  10.         QLineEdit *cast = qobject_cast<QLineEdit*>(o_list[i]);
  11.         if(cast)
  12.             cast->installEventFilter(this);
  13.     }
  14.  
  15. }
To copy to clipboard, switch view to plain text mode 

and

Qt Code: 
  1. bool MainWindow::eventFilter(QObject *obj, QEvent *event)
  2. {
  3.     if(event->type() == QEvent::MouseButtonPress)
  4.     {
  5.         Dialog mdialog;
  6.         mdialog.setModal(true);
  7.         mdialog.exec();
  8.     }
  9.     return false;
  10. }
To copy to clipboard, switch view to plain text mode 

I am wondering if its possible to automate this part

Qt Code: 
  1. ui->doubleSpinBox->installEventFilter(this);
  2.        //~~~~~~~~^
  3. QObjectList o_list = ui->doubleSpinBox->children();
  4.                           // ~~~~~~~~^
To copy to clipboard, switch view to plain text mode 

and to make sure I can return a value to a function that corresponds to what spinbox has been selected so that the dialog can return the new value to the appropriate field.

I really like the parameters and the look that the spinbox with no arrows gives so that's how I arrived at this juncture. Perhaps this more a C++ question than a Qt question, in any event IDK cause I'm a n00b.
