Take the 2-minute tour ×  By default the toolbar buttons in PyQT
are aligned to the left, is it possible to make them centered so
that they slide along when resizing?  share|improve this

am not sure I understand correctly, but if you are looking for a
way to center buttons on toolbar with respect to QMainWindow,
then yes there is a (hackish) way. You just need to put a widget
that acts like a 'spacer'. That is basically a QWidget with
expanding size policy.  Here is a minimal example:  import sys
from PyQt4 import QtGui  app = QtGui.QApplication(sys.argv) main
= QtGui.QMainWindow() toolbar = QtGui.QToolBar()  # spacer
widget for left left_spacer = QtGui.QWidget()
left_spacer.setSizePolicy(QtGui.QSizePolicy.Expanding,
QtGui.QSizePolicy.Expanding) # spacer widget for right # you
can't add the same widget to both left and right. you need two
different widgets. right_spacer = QtGui.QWidget()
right_spacer.setSizePolicy(QtGui.QSizePolicy.Expanding, QtG
