lxqt-leave: prefer QPushButton to QToolButton

[isf63]

QPushButton is generally styled "nicer" than QToolButton when the goal is dialog buttons. Tested on Fusion, Windows, and Kvantum themes.

Default focus was not an issue because it had default focus prior.

I think the same can be done in a few others places, if this has validity.

A matter of personal taste, not a reason to make a change. We talked about it before.

IMHO I think it's more than personal taste.

QDialogButtonBox and liblxqt use QPushButton's for a reason.

QToolButton has lousy styling with text + icon. It's primarily meant for toolbar or drop-down menus. See screenshots, I think this is fairly objective.

The only other place right now that I see benefiting from this (if this is sane) is Monitor Settings → Settings. Qt::TabFocus can be set to have no functional difference.

The same personal taste put into a totally subjective statement again ;)
