python 2.7 - How to hide or cut a Qwidget() text when I change main window size -

edit: when change main window size, need cut text of qlabel() includes in qstatusbar() fit size of form. shown in diagram below.

from pyqt4.qtgui import *  pyqt4.qtcore import *  import sys  class mymainwindow(qmainwindow):       def __init__(self):         qmainwindow.__init__(self)          self.setcentralwidget(qlabel("main widget"))          statusbar = qstatusbar()         self.setstatusbar(statusbar)          statusbar.addwidget(qlabel("first message"))         statusbar.addwidget(qlabel("second message"))         statusbar.addwidget(qlabel("a thrid long long long long long message"))  app = qapplication(sys.argv)   window = mymainwindow()     window.show() sys.exit(app.exec_()) 

the key set appropriate minimum width on labels, allow them resize smaller width of text. however, crop text on right, rather eliding (i.e. ... appears @ end).

the blog post status bar , elided label explains how elided text, solution written in c++. below equivalent version written in pyqt4:

import sys pyqt4 import qtcore, qtgui  class elidedlabel(qtgui.qlabel):     _width = _text = _elided = none      def __init__(self, text='', width=40, parent=none):         super(elidedlabel, self).__init__(text, parent)         self.setminimumwidth(width if width > 0 else 1)      def elidedtext(self):         return self._elided or ''      def paintevent(self, event):         painter = qtgui.qpainter(self)         self.drawframe(painter)         margin = self.margin()         rect = self.contentsrect()         rect.adjust(margin, margin, -margin, -margin)         text = self.text()         width = rect.width()         if text != self._text or width != self._width:             self._text = text             self._width = width             self._elided = self.fontmetrics().elidedtext(                 text, qtcore.qt.elideright, width)         option = qtgui.qstyleoption()         option.initfrom(self)         self.style().drawitemtext(             painter, rect, self.alignment(), option.palette,             self.isenabled(), self._elided, self.foregroundrole())  class mymainwindow(qtgui.qmainwindow):     def __init__(self):         super(qtgui.qmainwindow, self).__init__()          self.setcentralwidget(qtgui.qlabel("main widget"))          statusbar = qtgui.qstatusbar()         self.setstatusbar(statusbar)          statusbar.addwidget(elidedlabel("first message"))         statusbar.addwidget(elidedlabel("second message"))         statusbar.addwidget(elidedlabel("a third long long long long long message"))  app = qtgui.qapplication(sys.argv) window = mymainwindow() window.show() sys.exit(app.exec_())
