[matplotlib-devel] Enhancement to matplotlib's PyQt4 backend

[Pierre R. <co...@py...>]

Hi all,

I would like to contribute to matplotlib with this enhancement for the
PyQt4 backend: the idea is to add a toolbar button to configure figure
options (axes, curves, ...).

It's based on a tiny module called formlayout to generate PyQt4 form
dialog automatically.

Some screenshots:

So, if you're interested (all the following is GPL2):

*matplotlib patch*

In FigureManagerQT.__init__, added:
self.canvas.axes = self.canvas.figure.add_subplot(111)

In NavigationToolbar2QT._init_toolbar, added:
a = self.addAction(self._icon("customize.png"), 'Customize',
self.edit_parameters)
a.setToolTip('Edit curves line and axes parameters')

Added the following method in NavigationToolbar2QT:
def edit_parameters(self):
    from figureoptions import figure_edit
    figure_edit(self.canvas, self)

*additionnal modules and data*

formlayout.py (http://code.google.com/p/formlayout/)
figureoptions.py (http://code.google.com/p/PyQtShell/)

cheers,
