Widget for simple add / multiply editor.

class sas.qtgui.Utilities.AddMultEditor.AddMultEditor(parent=None)

Bases: QDialog, Ui_AddMultEditorUI

Dialog for easy custom composite models. Provides a Dialog panel to choose two existing models (including pre-existing Plugin Models which may themselves be composite models) as well as an operation on those models (add or multiply) the resulting model will add a scale parameter and a background parameter. The user can also give a brief help for the model in the description box and must provide a unique name which is verified before the new model is saved.

sas.qtgui.Utilities.PlotView module

class sas.qtgui.Utilities.PlotView.EmbeddedPylab(canvas)

Bases: object

Define a ‘with’ context manager that lets you use pylab commands to plot on an embedded canvas. This is useful for wrapping existing scripts in a GUI, and benefits from being more familiar than the underlying object oriented interface.

As a convenience, the pylab module is returned on entry.

Example

The following example shows how to use the WxAgg backend in a wx panel:

from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
from matplotlib.backends.backend_wxagg import NavigationToolbar2WxAgg as Toolbar
from matplotlib.figure import Figure

class PlotPanel(wx.Panel):
    def __init__(self, *args, **kw):
        wx.Panel.__init__(self, *args, **kw)

        figure = Figure(figsize=(1,1), dpi=72)
        canvas = FigureCanvas(self, wx.ID_ANY, figure)
        self.pylab_interface = EmbeddedPylab(canvas)

        # Instantiate the matplotlib navigation toolbar and explicitly show it.
        mpl_toolbar = Toolbar(canvas)
        mpl_toolbar.Realize()

        # Create a vertical box sizer to manage the widgets in the main panel.
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(canvas, 1, wx.EXPAND|wx.LEFT|wx.RIGHT, border=0)
        sizer.Add(mpl_toolbar, 0, wx.EXPAND|wx.ALL, border=0)

        # Associate the sizer with its container.
        self.SetSizer(sizer)
        sizer.Fit(self)

    def plot(self, *args, **kw):
        with self.pylab_interface as pylab:
            pylab.clf()
            pylab.plot(*args, **kw)

Similar patterns should work for the other backends. Check the source code in matplotlib.backend_bases.* for examples showing how to use matplotlib with other GUI toolkits.
