Thank you Juan. IIt looks like the event caught by the CanvasToolBase
are not whtn I am looking for (mouse click and keyboard events)

Hi Nadav,

I'm not sure I follow. The canvas tools use matplotlib events because the image canvas is drawn with matplotlib. The `CanvasToolBase` class shows an example of using the tool's `connect_event` to connect to "key_press_event" (keyboard events). The `LineTool` class shows an example connecting to keyboard events through "button_press_event".

Note that this event system is only for the image canvas. If another widget (e.g. a slider) has focus, then the events are handled by Qt's infrastructure.

Cheers,

-Tony

Thank you again,

Nadav
