问题 I am using the Qt4Agg (PyQt4) as the backend for rendering plots in matplotlib. This has a very useful toolbar with a very useful button 'Edit curve lines and axes parameters' . However, whenever I press it, it gives an error. (I know that it is useful as it works for bar graphs, but not for line plots :P). The cause and traceback can be seen clearly in the picture below.

问题 I'm developing a Swing based application in which I want to add JToolBar with images in JButton but it's not looking good. JToolBar is having some dots at the starting part. How can I get rid of the dots? 回答1: Two things: The "dots" you describe are probably due to the JToolbar being floatable by default. If you wish to disable this you can call setFloatable(false).
