How to Program custom Keyboard Shortcuts

Question

I have a Qt application on Linux.

I\'d like to program custom keyboard shortcuts such as CTRL-Q which will then call a subroutine which quits

Answer 1

this is a sample to create file menu and exit action and connection between signal and slot.

QMenu *fileMenu = new QMenu(trUtf8("&File"));
QAction *actionExit = new QAction(tr("E&xit"));    
//set "ctrl+q shortcut for exit action
actionExit->setShortcut(tr("CTRL+Q"));
//connect triggered signal of actionExit to close slot
connect(actionExit, SIGNAL(triggered()), this, SLOT(close()));
//add actionExit into file menu
fileMenu->addAction(actionExit);
