PyQt emulate minimize button "_"

How can I minimize window in PyQt the same way as w开发者_开发技巧hen _ is pressed?

I use

self.showMinimized()

It really minimizes window.

But there is no refocus to the previous window. As if focus is still on minimized window.

How can I minimize and refocus to the previous window as if minimize button _ is pressed?

Just Connect it this way

Minimized.clicked.connect(self.showMinimized)

(Copying Qiao's comment as an answer:)

I solved my problem with showNormal() and then showMinimized() once again.
