@L0uisc The simple answer is that Qt must have have hundreds of classes and thousands of methods. You could add useful/utility features forever. There is no deep reason why one is offered but not another, other than popular usage. QInputDialog --- which by the way is not used that often --- is only really a convenience class on top of QDialog. Nothing wrong with your suggestion --- and you can always make those at https://bugreports.qt.io/, or offer to implement it yourself --- just TQtC probably has a million other things to do :)
