-title: Finding mouse location in Python + GTK + OpenCV.

-- window1 (GtkWindow)
- - box1 (GtkBox)
- - grayscaleButton (GtkToggleButton)
- - eventbox (GtkEventBox)
- - image (GtkImage)
-```
-
-and in `eventbox` set the `Common -> Events -> Pointer Motion` so you can add
-a handler to the `motion-notify-event` event.
-
-Now you can write your handler:

- …
- …
- def onMotionNotifyEvent(*args):
- global current_mouse_location
-
- event = args[1]
-
- current_mouse_location = event.x, event.y

-title: Handling Python/GTK's GtkScale value-changed event.
-date: 2022-01-29
-
-It took me way too long, but now I know how to handle the value-changed event of GtkScale.
-
-In Glade:
-
-1. Create a GtkScale widget. We will ID it `foo_scale`.
-2. In the `Signals -> GtkRange -> value-changed` line change the `Handler`
- field to something sensible like `on_foo_scale_value_changed`. That will
- be the name of the handler.
-3. Make a new Adjustment in:
-
- ```
- General ->
- Adjustment ->
- (little pen button in the field) ->
- Choose a [sic] Adjustment in this project ->
- New
- ```
-
-4. Rename the adjustment to something sensible like `foo_adjustment` and set
- the `Value`, `Minimum Value`, `Maximum Value`, etc. Those are kind of self
- explanatory…
-5. In Python, your handler will be called with a single argument - the signal
- emitting object, which is the GtkScale object itself. It has a method,
- `get_value()`, used to get its current value:
-
- ```python
- def on_foo_scale_value_changed(emitter):
- scale_value = emitter.get_value()
- do_stuff_with_scale_value(scale_value)
- ```
-
-Fin.
