Give away focus?
Message 1 in thread
I'm using Qt 4.3.2.
Is there any way for my application to throw away focus?
I'm running automated tests, and ever time my app starts up again, it
steals focus
from where I'm trying to get some work done. (If I could "reject" focus,
I would
have a (say) command line option -testMode that would throw focus back
to where
I'm trying to do work.)
I found KDE's "Focus Under Mouse" as opposed to "Focus Follows Mouse"
but "under mouse" has the unfortunate side effect of preventing me from
getting
Google Calendar pop-ups.
If it's isn't possible to do this in Qt, does anyone know how to do it in X
(or KDE or Linux or whatever.)

void QWidget::clearFocus ()?

This doesn't seem to do what I want. I want the "whole" application to
loose focus.
(I called clearFocus on my QMainWindow)
Any other thoughts on this?

This is a window manager issue, not something specific to Qt. For the X
window system you can try manipulating the XWMHints structure to set the
input mode to no input for testing. See the Xlib Programming Manual, Vol
1, Chapter 12

Thanks. I figured it might be outside of a "normal" Qt concern.

According to my understanding There is only one Widget which may have
focus in the system.
So you need to move focus to other widget, which does not belong to your
application to lose it.
I am not sure why do you need to do this, but probably you can move it
to the desctop widget.
QT4 seems provides QDesktopWidget widget which should help you.
QDesktopWidget w;
int sc = primaryScreen ();
QWidget*p = w.screen ( sc );
p->setFocus();
This is just an idea, code was not tested.

Let me rewrite your idea.
Prog. A : main program
Prog. B : test program
Prog. A calls Prog. B. Then Prog. B give away focus.
Then Prog. A continue the job.
Is this correct?
Then, I think it is hard.
Prog. B's giving focus away never means Prog. A gets the focus again.
I think there are two scenario possible.
1. Change the structure so that Prog. B calls Prog. A.
2. Prog. A waits Prog. B to finish initializing jobs, then
Let Prog. A grab the focus. (You may need inter-process communication)
In similar situation with windows. I tried #2 scenario. It worked.
When I did that, Prog.A peeked the window messages to Prog. B.

I run my automated tests in Xvfb and/or Xnest. With Xvfb, I never see the GUI
show up, and I can even have the GUI tests run while I'm not logged into the
machine. Xnest is nice if you want to see many tests run, but not steal
focus away from other apps, except the first time Xnest is started up.

Another option is Xvnc. You also don't need a real display to run the
tests (like Xvfb) but can connect to it with any VNC server from
anywhere to see what is going on esp. if you need to look at any isseus.
In addition you could use Vmware or any other virtual machine which you
can just minimize.

Thanks. I tried to find a "null x server" with Google but obviously
didn't find
the right terminology. Xvfb (X Virtual Frame Buffer) will certainly do
the trick.
