{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"wx segfault","articleBody":"The following script (opening two figures, and triggering a figure quit via the keyboard shortcut on a timer 1 second after the second figure is drawn) segfaults when used with the wx{,agg} backend.  It works as expected (closing the second figure after 1s) e.g. other backends.\r\n\r\n```\r\nfrom pylab import *\r\n\r\nplt.figure()\r\n\r\nfig = plt.figure()\r\ntimer = fig.canvas.new_timer(1000)\r\ntimer.add_callback(fig.canvas.key_press_event, \"q\")\r\nfig.canvas.mpl_connect(\"draw_event\", lambda event: timer.start())\r\nplt.show()\r\n```\r\n\r\nInterestingly, commenting out the first `plt.figure()` (which seemingly plays no role...) removes the segfault.\r\n\r\nNoted while working on the tests for #11581.\r\nMatplotlib master on Py3.6/Arch Linux.","author":{"url":"https://github.com/anntzer","@type":"Person","name":"anntzer"},"datePublished":"2018-07-05T23:12:16.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/11582/matplotlib/issues/11582"}
