Gtk scroll window size in a grid

Experimenting with Gtk+3 in python.

Trying to add a "Gtk.TreeView" inside a scroll window container to a grid window along with an entry box. The problem is that the scroll area is tiny and as a result you can barely see any of the scroll window/TreeView. Here is an image of the output:

enter image description here

The relevant code is:

scroll = Gtk.ScrolledWindow()    # Create scroll window
scroll.add(self.MatchTree)       # Adds the TreeView to the scroll container

grid = Gtk.Grid()                # Create grid container
self.add(Grid)                   # Add grid to window (self)
Grid.add(scroll)                 # Add scroll window to grid
Grid.attach_next_to(self.Entry, scroll, Gtk.PositionType.BOTTOM, 1, 1)  # Attach entry to bottom of grid.

So how do you control the size of the scroll area?

Cheers, Phil

What you need to do is to set the hexpand and vexpand attributes of the GtkScrolledWindow to True. You can do this on object creation like this:

scroll = Gtk.ScrolledWindow(hexpand=True, vexpand=True)

If you are up to it, I recommend you use Glade to work your program's interface, it makes a lot simpler to work out this kind of problems, since you have easy access to all the widgets properties.
