Qt - catching interrupts

I am using Qt on an embedded ARM dev board. It has a few push buttons that I would like to use as control for my Qt application.

Does anyone have any ideas on how I can get Qt to catch interrupts and then do a slot action on it? I would like to basically map some of the buttons as the keyboard up-down-left-right arrows.

For instance if I have a ListView, I would like to be able to use buttons to scroll up and down the list.

If anyone has any suggestions or readings regarding this.

Thanks for the help.

QWidget::keyPressEvent(), QWidget::keyReleaseEvent(), QShortcut...?

I assume you are talking about hardware interrupts. Qt is not an OS, so you cannot "catch interrupts" using Qt but have to install your own OS-base IRQ handler.
