How to set the flag to get rid of the close button (x) sitting at the
most right-top corner of a dialog?

You need to set some window flags on the dialog. I can never remember them
exactly, but reading the documentation should get you to the correct set.
IIRC, you need to set Qt::CustomizeWindowHint | WindowTitleHint on the dialog
to get a dialog that has a title bar but no close button.
You need to be careful with this, though. Unless you have a really good reason
for doing it, users aren't going to appreciate you taking away their close
button.

Also, notice that these are only hints to the underlying window
system. Not every window manager respects them.

It's supported on Windows and Mac OS X and all recent (decent) window managers
on Unix/Linux platforms. If users want to run on some odd window manager that
doesn't support this, they chose it themselves. Don't worry about it, it's
only a theoretic issue.

Bo,
Thank you for your informative reply.
Problem solved by subclass the QDialog using the correct flag:
ProgressCtrl::ProgressCtrl(QWidget *parent) : QDialog(parent,
Qt::WindowTitleHint)
The reason why I take away the close button is:
Progress control is designed for thread:
Suspend/Resume/Stop/Kill(terminate).
The control is a modaless dialog, which shows up when a thread emits
started() signal, and hide when the thread emits finished() or
terminated(). At this circumstance, I have no job assign to the
close-button, so I remove it.
Regards,
Lingfa
