如何調試在wxpython/python線程中崩潰的wxpython應用程序

我有一個叫做h2hh的wxpython應用程序。 OSX上的用戶正在重複崩潰並提供了附加的崩潰轉儲。如何調試在wxpython/python線程中崩潰的wxpython應用程序

我甚至不知道從哪裏開始調試！幫幫我？我怎麼開始？即使對於一些可能會給我提示的問題，我也會很感激......

謝謝！在http://gregories.net/images/crashdump.txt

完全崩潰轉儲確保您不能直接從一個線程調用WX方法。如果你這樣做，那麼你正在做一些未定義的事情，並會導致問題。您必須改用wx線程安全方法，例如wx.CallAfter，wx.CallLater或wx.PostEvent。如果你在一個線程中調用了像myControlSetValue（）這樣的東西，你就會遇到問題。

我推薦你問一下wxPython郵件列表。那裏有幾個Mac傢伙，其中包括一些核心開發人員。

謝謝，我會研究這個，一個很好的領導。我想 - 我有CallAfter等，但絕對是我的開始！ – GreenAsJade

剛回來說這是現貨。我發現了一個定時器回調函數，它直接調用wx而不是CallAfter（）。謝謝！ – GreenAsJade
