Raising an error saying that not enough arguments are passed to standardPixmap when called out of Nuke 14.0 (Qt 5.15.2.1).

Per the PySide2 documentation, https://doc.qt.io/qtforpython-5/PySide2/QtWidgets/QStyle.html#PySide2.QtWidgets.PySide2.QtWidgets.QStyle.standardPixmap it is recommended to use standardIcon instead.

Changing:

         close_btn = QtWidgets.QPushButton()
-        close_btn.setIcon(QtGui.QIcon(
-            self.style().standardPixmap(
-                QtWidgets.QStyle.SP_DialogCloseButton
-            )
-        ))
+        close_btn.setIcon(self.style().standardIcon(
+            QtWidgets.QStyle.SP_DialogCloseButton)
+        )

seems to do the trick, but also needs to be done for

After fixing these 2 I was able to display my nodes in the properties bin.
