Pass value to dialog

[waynew]

Opening a dialog from the main window menu and I need to pass a QSqlRecord to it.
I have the record value, and I suspect the answer is signals & slots.
I can make the slot in the dialog, but what would the signal from the main window be?
I'm still having trouble grasping the full power of signals & slots.

Here is what I have so far.

void MainWindow::on_actionEdit_Log_Entry_triggered()
{
   if (::open_log != "") {
       QModelIndex index = view->currentIndex();
       QSqlRecord record;
        int i = index.row();
        record = model->record(i);
        qDebug() << "record is " << record;  // record looks good, need to pass it.
       EditLog *edit = new EditLog(this);
       edit->show();
   }else{
       QMessageBox::information(this, "Edit Log", tr("A log must be open to edit it."));
   }
}

void MainWindow::on_actionEdit_Log_Entry_triggered()
{
   if (::open_log != "") {
       QModelIndex index = view->currentIndex();
       QSqlRecord record;
        int i = index.row();
        record = model->record(i);
        qDebug() << "record is " << record;  // record looks good, need to pass it.
       EditLog *edit = new EditLog(this);
       edit->show();
   }else{
       QMessageBox::information(this, "Edit Log", tr("A log must be open to edit it."));
   }
}

Any help please?

In this case you do not need to use signals. Just add function like setRecord(QSqlRecord
