我在框架 中有一個標籤和文本小部件，用作狀態欄。當光標移動 （通過按任意鍵或回車鍵），狀態 欄顯示位置。但更新速度較慢 並且當快速或重複按下「鍵」時，光標位置編號停止位顯示新的光標位置 。這裏是我的代碼...當光標移動時，光標位置統計信息更新緩慢
更新：
我張貼一些代碼，有人問我要發佈更多的代碼。 這裏是整個程序。希望它不多。我也有 文字部件（txt1）隨着所選 增加的字體大小而增大的問題。
請忽略搜索文本的功能，我只是盯着今天與 玩弄它的亂七八糟的一點點，
謝謝，韋恩。

你能顯示更多的代碼嗎？例如無論創建「主人」。足以實際運行某些東西會更可取。 –
我們不需要_whole_代碼。請刪除與問題無關的代碼。如果問題是在綁定上顯示信息，則只需要文本小部件，綁定語句，綁定使用的函數以及幾行代碼將它們粘合在一起。請閱讀並遵循[如何創建最小，完整和可驗證示例]的建議（http://stackoverflow.com/help/mcve） –
