wxPython使面板不能通過標籤訪問

Question

我使用wx.glade構建了一個gui。這個GUI的一部分是輸入密碼的部分，然後單擊一個按鈕來驗證它們。爲了製作這個部分，我使用了一個網格分割器。並非網格中的每個單元格都需要有按鈕或字段，因此我用wx.panel組件填充爲間隔符。

會發生什麼事是因爲我通過tx字段和按鈕選項卡一切正常，但wx.panel間隔符也是該選項卡列表的一部分。我想要做的是讓他們無標籤可選。

Answer 1

面板通常本身不接受焦點，所以這有點奇怪。您可以捕獲焦點事件，並告訴它將焦點置於下一個小部件上，假設您自己跟蹤Tab鍵順序。或者你可以嘗試禁用面板，它應該有相同的效果。

Answer 2

也許我誤解了你，但爲什麼不直接使用spacer呢？他們似乎正是爲此而設計的，並不會接受的標籤... wxglade對其有一個按鈕，他們評價到：

sizer.add((20,20) 1, wx.EXPAND, 0) 

是20×20像素間隔的標稱大小，但你可以申請通常的一組標誌來調整調整行爲。
