There is no toolbar widget in QtDesigner, but you can add the toolbar by code:

Here is the example, the plot_layout is a QVBoxLayout designed by QtDesigner, and plot_canvas is the MatplotlibWidget widget.

import numpy as np
from PyQt4.QtCore import Qt
from PyQt4.QtGui import *
from matplotlib.backends.backend_qt4 import NavigationToolbar2QT as NavigationToolbar
from plot_dialog2 import Ui_Form

class PlotDialog(QWidget, Ui_Form):
    def __init__(self):
        QWidget.__init__(self)
        self.setupUi(self)
        self.navi_toolbar = NavigationToolbar(self.plot_canvas, self)
        self.plot_layout.addWidget(self.navi_toolbar)

if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)
    dialog = PlotDialog()
    dialog.show()
    sys.exit(app.exec_())
