Hi everyone,
I'm new here and I have a question ( I guess as everybody who is new
here ;-) ),
I'm having some strange problem with Matplotlib, using it in a Tkinter
application.
I create a Canvas, a figure, subplot and then a toolbar. It works
fine, but only without the toolbar! When I want to add the toolbar, I
get an error
File "./tkViewer.py", line 102, in setupGUI
self.toolbar = NavigationToolbar2TkAgg( self.canvas, master )
File "/usr/lib/python2.4/site-packages/matplotlib/backends/
backend_tkagg.py", line 537, in __init__
NavigationToolbar2.__init__(self, canvas)
File "/usr/lib/python2.4/site-packages/matplotlib/backend_bases.py",
line 1107, in __init__
self._init_toolbar()
File "/usr/lib/python2.4/site-packages/matplotlib/backends/
backend_tkagg.py", line 577, in _init_toolbar
borderwidth=2)
File "/usr/lib/python2.4/lib-tk/Tkinter.py", line 2378, in __init__
Widget.__init__(self, master, 'frame', cnf, {}, extra)
File "/usr/lib/python2.4/lib-tk/Tkinter.py", line 1865, in __init__
self.tk.call(
_tkinter.TclError: bad screen distance "500.0"
Here is the part my code:
self.canvFrame = Frame(master)
self.canvFrame.pack(side=TOP, fill=BOTH, expand=1)
self.canvFrame2 = Frame(self.canvFrame)
self.canvFrame2.pack(side=LEFT, fill=BOTH, expand=1)
self.f = Figure(figsize=(5,4), dpi=100)
self.a = self.f.add_subplot(111)
self.subplAxis = self.f.get_axes()
self.canvas = FigureCanvasTkAgg(self.f,
master=self.canvFrame2)
self.canvas.show()
self.canvas.get_tk_widget().pack(side=TOP, fill=BOTH,
expand=1)
self.toolbar = NavigationToolbar2TkAgg( self.canvas,
self.canvFrame2 )
self.toolbar.update()
self.canvas._tkcanvas.pack(side=TOP, fill=X, expand=1)
master is a parameter passed to my method, which actually is set to
Tk()
What did I get wrong? What is the problem? Thanks in advance...
Thorsten
