How to apportion HSplit in traitsui-generated window

In this code, there is the following:

view = View(HSplit(Item('figure', editor=MPLFigureEditor(),
                        dock='vertical'),
                   Item('panel', style="custom"),
                   show_labels=False,
                  ),
            resizable=True,
            height=0.75, width=0.75,
            handler=MainWindowHandler(),
            buttons=NoButtons)

The HSplit divides the window into two panels of equal size. What can I do to make one panel take up 1/3 of the space while the other occupies the other 2/3 of the space in the window. I have done a lot of source diving and read the online documentation, but I am not having any luck.

Any help appreciated!

Solution

  • Please see the example here, which you can extend to a split:
