Updating a QTableWidget through a Dialog

[vitaly]

1: contactDialog dlg(this);
2: if(dlg.exec() == QDialog::Accepted)
3: dlg.leBedrijf->setText(item->text());

You try to set some dialog properties in the string 3 (see quoted text) after the dialog is executed and closed (string 2) because the dialog is modal. Try the following:

ContactDialog dlg(this);
dlg.setSomeField(item->text());
if (dlg.exec() == QDialog::Accepted) {
    // Do something
}

ContactDialog dlg(this);
dlg.setSomeField(item->text());
if (dlg.exec() == QDialog::Accepted) {
    // Do something
}

To copy to clipboard, switch view to plain text mode
