I'm developing a software for Geology, using wxpython for the GUI.
When I want to export any graphics, clicking on the
"save" button on the MPL toolbar, I get a dialog to save the file
(with a default "image.png" filename) and where I
can choose between some file formats. When I select any format from
the drop-down list, I expected it to change the extension
of the file on the dialog, but it doesn't. So I have to set it up
manually. Is this a bug?
