我创建了一个qt应用程序，可用于在多个选项卡中显示matplotlib数字。现在，我正在尝试获取标准的matplotlib导航工具栏，以使其适用于各个选项卡中的所有图形。到目前为止，我只设法使它适用于其中一个数据，但不是全部。

这是代码：

from PyQt4 import QtCore
from PyQt4 import QtGui as qt

from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt4agg import NavigationToolbar2QTAgg as NavigationToolbar
from matplotlib.figure import Figure

import itertools

class MultiTabNavTool(NavigationToolbar):
    #====================================================================================================
    def __init__(self, canvases, tabs, parent=None):
        self.canvases = canvases
        self.tabs = tabs

        NavigationToolbar.__init__(self, canvases[0], parent)

    #====================================================================================================
    def get_canvas(self):
        return self.canvases[self.tabs.currentIndex()]

    def set_canvas(self, canvas):
        self._canvas = canvas

    canvas = property(get_canvas, set_canvas)

class MplMultiTab(qt.QMainWindow):
    #====================================================================================================
    def __init__(self, parent=None, figures=None, labels=None):
        qt.QMainWindow.__init__(self, parent)

        self.main_frame = qt.QWidget()
        self.tabWidget = qt.QTabWidget( self.main_frame ) …
