You can run this script from any body pane:
---cut here---
from PyQt4 import QtGui
class MatplotPaneProvider:
def __init__(self, c):
self.c = c
if hasattr(c, 'free_layout'):
splitter = c.free_layout.get_top_splitter()
if splitter:
splitter.register_provider(self)
def ns_provides(self):
return[('Add matplot', '_add_matplot_pane')]
def ns_provide(self, id_):
if id_ == '_add_matplot_pane':
c = self.c
w = QtGui.QSlider()
return w
def ns_provider_id(self):
# used by register_provider() to unregister previously registered
# providers of the same service
# provider ID is not the same as the service id_ above
return "completely unique value here"
MatplotPaneProvider(c)
---cut here---
Paste just as above and run the script. Nothing happens. Right click
on one of the pane dividers and select Insert. A new pane with a
button 'Action' appears. Click it, and select "Add matplot" from the
context menu.
Instead of "w = QtGui.QSlider()", you want "w = myMatplotWidget()"
