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,

Hi Nadav,

I don't have much experience with interactive tools, but I think this is

You'll see that the LineProfile plugin uses the LineTool canvas tool:

I I started to build an interactive image exploration utility based on matplotlib. Recently, following a link on this list, I encountered skimage.viewer, and found that the plugins architecture matches my

needs.

I could not find how to link keyboard and mouse events (and maybe buttons) to plugins. Any suggestions?

I am using version 0.93 on linux (I can install the pre 0.10, if needed)

Thanks,
