- The old code used two QPushButtons in a QHBoxLayout to provide
Ok/Cancel buttons. This hard-codes the positions and text (and
icons) of these buttons, instead of adapting to the platform style.
The new code simply uses QDialogButtonBox, which is designed for
this purpose.
- Also, the old code connected the Ok button's clicked() signal to a
custom slot that then called QDialog::accept(). This means that the
code in the custom slot is not executed when the dialog is accepted
by other means (e.g. return press in one of the line edits
("auto-default"), though I'm not sure here).
The new code uses the idiomatic Qt way of overriding
QDialog::accept() instead, and connects the button-box's accepted()
signal to it. This is done in the .ui file, so it already works in
Designer preview.
- Finally, the old code made a manual connection from the Cancel
button to QDialog::reject().
The new code uses the Qt idiom of connecting in the .ui file
directly, using QDialogButtonBox::rejected() as the signal.
Amends 2690822428deec4f0c08f4d118d69a7c6036369e, which, however,
inherited all of the above from even older code.
