How to start the log file when key combinations pressed??

Yes but your dialog needs to accept focus to receive key events. How many times do I have to say it for you to understand?

How to make the dialogs to accept the focus??

[wysota]

Go to QWidget API and keep reading it until you find something that might indicate that it's related to focus.

If you have a GUI application you can use QShortcut or QAction.

I have used the following code.. it works fine in xp(Qt 1.3.1) but it is not working in windows 7.,(Qt 4.3)::

QShortcut *shortcut = new QShortcut(QKeySequence("Ctrl+M"), this);
        QObject::connect(shortcut, SIGNAL(activated()), this, SLOT(showmessage()));

QShortcut *shortcut = new QShortcut(QKeySequence("Ctrl+M"), this);
        QObject::connect(shortcut, SIGNAL(activated()), this, SLOT(showmessage()));

To copy to clipboard, switch view to plain text mode

For the last time: shortcuts, key events and such work in terms of focus. One of children of the window containing the shortcut needs to have focus for the shortcut to trigger.
