How can I let a window can't iconify?

for example, let a specifically rxvt window can’t iconify.(Isn’t let all rxvt windows can’t iconify)

Pick WindowStyle !Iconifiable

or maybe

Pick ThisWindow ("rxvt") WindowStyle !Iconifiable

thank you.
“Style XXXrxvt !Iconifiable”, the question is solved.
I mistake for the “!Iconifiable” isn’t a property of the “Style”.:slight_smile:

then how can I clear up the beep that when I perform the “Iconify”?

What beep are you talking about?

That would be because of something taking thumbnails as screenshots as the window is iconified.
