My use case requires selecting from a set of points that are distributed in a way that is unsuitable for selection with a rectangle.

Re: [matplotlib-devel] Alternate lasso: click to form polygon
I tried with the Tk backend, and I'm seeing the same problem as Eric F has with GTK. The problem seems to be with idle_event not getting triggered on some of the backends. The checkins having to do with idle_event from the end of June indicate that idle_event is still somewhat experimental. What's the current status of idle_event? Can I help in some way? If idle_event can't be made robust, I'll need to look for another method to address the following problem. When I close off the polygon, I determined that I needed to fall back to the idle state to be able to see the closed polygon. My code, itself triggered off a right mouse click, was apparently blocking drawing to the screen. It is desirable to see the closed polygon on screen before the polygon callback in the event that the callback takes a long time.

Can I help in some way? I was working on idle event, to make a backend neutral api for idle processing, animation, etc... There was a particularly nasty problem with tk since I had to do the threading calls myself and I am no threading guru, so I reverted some of the changes, mainly because of the problem of cross thread signal handling blocked the CTRL-C interrupts. These changes were added in r5652 r5652 | jdh2358 | 2008-06-23 16:39:11 -0500 (Mon, 23 Jun 2008) | 1 line draft idle/timeout api and subsequent refactoring r5653 | jdh2358 | 2008-06-23 23:17:21 -0500 (Mon, 23 Jun 2008) | 1 line replaced idle handler with idle event but then reverted when Nils reported the CTRL-C bug in r5655 | jdh2358 | 2008-06-24 08:56:55 -0500 (Tue, 24 Jun 2008) | 1 line removed idle support from tkagg until I figure out interrupts So the implementation is incomplete and tkagg needs to most work, since for other GUIs it is fairly easy to pass through the native enent handling. I am not sure what the problem is with GTK right now, and haven't had a chance to look at it.
