搖擺的問題與消失的JTextField

我在NetBeans中工作，努力做我的項目，但我已經遇到了一個問題。基本上，我建立一個數字計時器，則顯示作爲毫秒作爲佈置在8.搖擺的問題與消失的JTextField

這樣的形狀7個文本框：

_ 
|  | 
    _ 
|  | 
    _

每個毫秒我使某些文本字段不可見的顯示不同的數。比我有一秒顯示（當毫秒計數到10時）顯示例如秒1，2，3 ...但由於某些原因，當毫秒達到10時，中間文本字段消失並且不再顯示。我不知道什麼可能會導致這個問題。

這裏是我的代碼：

我已經採取了調整標題和標籤的自由，因爲這是一個真正的的Java Swing問題。 – madth3

你爲什麼使用JTextFields？只需將組成8形狀的條形圖繪製到JPanel的擴展上即可。 –

一秒內有超過10毫秒（準確地說1000）。 –

由於madth3指出，一旦某個組件變得不可見，它不再被大多數佈局管理器認爲，當他們計算有佈局。

雖然我可以想到解決此問題的100種不同方法，但下面的示例使用一個簡單的JPanel，它充當段並使用時髦的alpha彩色技巧來「隱藏」不會影響現有佈局的段。

你好感謝你的答案，但我需要做的具體的方式正如我所說的，因爲它需要單項目，我可能已經做到了這一點不同的，更有效的方式，但必須遵守規則;/ – Ilja

因此，而不是使用面板，用文本字段替換它們 – MadProgrammer

對於初學者我不得不說這是一個非常不尋常的實施數顯示的。更改元素的可見性可能會導致組件重新排版併發生類似問題。

該問題是由於呼叫更改按鈕oneSecsDisplay上的圖標造成的，因爲可以看到註釋呼叫showOneSecsActionPerformed。佈局重新包裝了一切，它在中間消失了JTextField。

我在GroupLayout的專家，但可能短期的解決辦法是把所有的TextField到它自己的面板。從長遠來看，我同意@whiskeyspider推薦a drawing alternative。
