it originally had shown the following structure:
+```
- window1 (GtkWindow)
- box1 (GtkBox)
- grayscaleButton (GtkToggleButton)
- image - (GtkImage)
+```
but if you want to find the mouse location, put your GtkImage inside a GtkEventBox:
+```
- 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.
