My guess is that clicking on a collection causes a pick event to be returned
by the collection itself and also perhaps by the barh member in the
collection. No idea if that's the case, but just for the record, I figured
out a simple enough workaround in which the pick handler is disconnected to
open a wxPython popup window. Once that window is closed, the pick handler
is reconnected:
self.evt_bind = self.canvas.mpl_connect('pick_event', self.on_pick)
. . . .
def on_pick(self, event):
if type(event.artist) == brokenbarh:
self.canvas.mpl_disconnect(self.evt_bind)
popup = popupwin(self, event.mouseevent.xdata,
event.mouseevent.ydata)
popup.Popup()
class popupwin(wx.PopupTransientWindow):
def __init__(self, plot, x_coord, y_coord):
wx.PopupTransientWindow.__init__(self, plot)
self.plot = plot
text = st.gen(self, 'hello')
def OnDismiss(self):
self.plot.evt_bind = self.plot.canvas.mpl_connect('pick_event',
self.plot.on_pick
