2021 edit: 群益的 python demo 範例已經提供 tkinter 很好的實作範例了
最近嘗試用 python GUI 實做群益附的範例 SKCOMtester 的功能，一開始用tkinter來做，但都會當掉，當我按下Login 鈕後，Console 會出現一連串類似下圖的訊息
後來改用 wx 雖然還是有同樣的錯誤訊息，但確仍能繼續執行, 有人知道怎麼解決這個錯誤嗎?
初次使用python GUI, 不太孰悉，未來GUI的layout 應該要單獨一個檔，才會比較好管理，目前已能動為優先。
很多人跟我說 Event 出不來，我覺得有GUI介面的話，很高機率可以解決這個問題!
使用流程，
1. 輸入ID&PW後Login，會等個幾秒，console出現一串錯誤訊息
2. 按 Connect 登錄報價伺服器，當出現 nCode=3003後, 表示完成登錄
3. 在Quote 欄填寫代碼，按下 Request 即可取得報價，預設是取台指近月期貨(TX00)
環境:
WinXP 32 bit, Capital API 2.3.9, python 3.4.3
