Issue:
GTK+: TypeError: on_close() takes 2 positional arguments but 3 were given
When creating a new Window and then closing it a TypeError is created in Linux. Once you have created an App, calling the following will reproduce the error:
    
    window = toga.Window()
    window.app = app
    window.show()

Then close the window and you get:

    TypeError: on_close() takes 2 positional arguments but 3 were given

Issue:
Menu items broken on Cocoa backend: fails with object has no attribute '_menu_items'
I believe this is a regression from 1d41d3833eb4b8785faf8eb7850f3feec4650350 / #373. The changes `appDelegate.interface` from the `App` instance to `App.interface`. Unfortunately, selecting a menu item still expects `appDelegate.interface` to be the `App` instance, see below where it calls `self.interface._menu_items`:

https://github.com/pybee/toga/blob/ad91f1a65a109b670256028e31c887dc18a4876d/src/cocoa/toga_cocoa/app.py#L71-L75

## Expected Behavior
The action successfully runs.

## Current Behavior
The action doesn't run, you get an error in the terminal:

AttributeError: 'TogaDemo' object has no attribute '_menu_items'
```

## Steps to reproduce

1. Run the toga demo app (`cd toga && python -m toga_demo`)
2. Click on one of the "Commands" > "Action 1"

## Your Environment

* Python 3.6.
* macOS High Sierra
* Toga Target: cocoa


Discussion:
A simple fix for this to call `interface._impl`, but that seems incorrect since `_impl` is private?

Your analysis looks right to me, as does the fix. 

`_impl` is private from the perspective of users of the interface; but it's considered fair game if you're already on the implementation layer.

Hrm... which tutorial is this (i.e., tutorial 0? tutorial 1?)

On a related note - if you've got any tips/pointers on how to run automated tests of GUI code on Windows, I'd love to hear about them - at the moment, we're only doing automated testing of internal APIs, so calls on GUI functionality are *far* too succeptible to breakage.

Issue:
Add Canvas Dashed Line Support for Gtk+
Hey PyCon AU 2018 sprinters, and other new contributors - here is a great way to contribute for someone who runs Linux:

Recently @bryall implemented dashed line support for Canvas in the Cocoa backend in #578. It would be great to implement support for dashed lines in Gtk+ as well.


Discussion:
This seems a little bit over my head, but mind if I take a shot at it?
you can do it, let me know if you need any help.
@bryall I'm not sure if you ran into this problem, but since only the dash pattern is given, how do you find the number of dashes to use to fill the widget?
the set_dash() function on the draw context accepts an array of the dash pattern. The dash pattern array defines the pattern of the dash stroke on the canvas. So you are defining the pattern and the subsequent draw commands will use that pattern on every pen move till the stroke on the draw context changes. Hopefully that was clear, let know if you have any other questions.

The literals in the file won't work in Python 3, and by fixing them you can get as far as an empty window on Windows.

Issue:
Setting `Table(missing_value="")` does not silence the warning about a missing value in data
**Describe the bug**
Explicitly setting `Table(missing_value="")` (i.e. the empty string and not `None`) does not silence the warning about the missing value:
```
WARNING: Using empty string for missing value in data. Define a 'missing_value' on the table to silence this message
```

**To Reproduce**
Steps to reproduce the behavior:
1. Go to https://toga.readthedocs.io/en/latest/tutorial/tutorial-2.html
2. Run the code
3. Notice the terminal says, `WARNING: Using empty string for missing value in data. Define a 'missing_value' on the table to silence this message`
4. add `missing_value=""` to the `toga.Table()` call
5. Re-launch the app
6. Notice the warning persists

**Expected behavior**
To have no warning when the empty string is specified.

Issue:
Toga scrollbar breaks with macOS Natural Scrolling preference
## Expected Behavior
Scrolling in Toga windows should be reflected in the scrollbar.

## Current Behavior
When debugging the Toga ``DetailedList`` example in ``toga/examples/detailedlist``, I noticed that the scrolling direction was reversed from the trackpad direction (since I have macOS natural scrolling enabled), however the scroll bar moved in the reverse direction.

## Steps to reproduce

On a computer running macOS with Natural Scrolling enabled (set this in `System Preferences > Trackpad > Scroll & Zoom`):
```
cd toga/examples/detailedlist && python -m detailedlist
```

(this example will crash. this is already documented in issue #549.)

Issue:
Not specifying an `on_select` callback for Table leads to a TypeError
**Describe the bug**
If you leave out a `on_select` callable on `Table` and click a row, you get a traceback in the terminal:
```python
Traceback (most recent call last):
  File "C:\\Users\\brcan\\Desktop\\snippets\\.venv\\lib\\site-packages\\toga_winforms\\widgets\\table.py", line 74, in _native_item_selection_changed
    self.interface.on_select(self.interface, row=self.interface.data[e.ItemIndex])
TypeError : 'NoneType' object is not callable
```

**To Reproduce**
Steps to reproduce the behavior:
1. Go to https://toga.readthedocs.io/en/latest/tutorial/tutorial-2.html
2. Run the example
3. Click on any row of the table
4. See error

**Expected behavior**
No error.

**Environment:**
 - Operating System: Windows 10
 - Python version: CPython 3.8.3
 - Software versions:
   - Briefcase:
   - Toga: 0.3.0dev22
   - ...



Discussion:
Thanks for the report! Looks like an oversight on the event handling of the Windows backend.
