PySide2 QToolButton stylesheets

[iLLiCiT]

Hi, I've question about stylesheets of QToolButton and different popupMenu property values. Because it seems that PySide2 store popupMenu property as object so (for example) this stylesheet is ignored:

QToolButton[popupMenu="1"] {
    padding-right: 20px;
}

Python part:

tool_btn = QtWidgets.QToolButton()
tool_btn.setText("Test")

tool_menu = QtWidgets.QMenu(tool_btn)

tool_btn.setMenu(toolmenu)
tool_btn.setPopupMode(QtWidgets.QToolButton.MenuButtonPopup)

I've fake it using custom property but that's not ideal as I want to use it as global stylesheet which should be applied on any widgets outside of my project.

# Set custom propert name
tool_btn.setProperty("popup_menu", "1")

/* Both properties with same stylesheet */
QToolButton[popupMenu="1"], QToolButton[popup_menu="1"] {
    padding-right: 20px;
}

Has anybody idea how it's doable?

Using: Python 3.7.6, PySide2 5.15.2

Ok so I found out that I had to use MenuButtonPopup as value

QToolButton[popupMode="MenuButtonPopup"] {
    padding-right: 20px;
}
