所有選項卡末尾的按鈕關閉窗口

Question

我有一個要求，將最小化和關閉按鈕放在我的JTabbedPane結束的右角。爲了清楚起見，圓圈區域是兩個按鈕，我需要（我有一個未修飾的幀）

任何人都可以請指導我如何實現這一目標？我的問題是（更多）按鈕定位（在JTabbedPane上），而不是實現最小化/關閉的功能

謝謝！

Answer 1

所有添加到JTabbedPane中的組件都將被包裝在標籤中。這意味着將按鈕直接添加到JTabbedPane是不可能的。如果您希望直接將關閉按鈕和最小化按鈕作爲選項卡窗格的一部分（而不是稍微放在一邊），我建議使用按鈕將自定義選項卡組件（JTabbedPane.setTabComponentAt()）添加到選項卡窗格中。由於該按鈕是該選項卡的唯一組件，選擇實際的「選項卡」本身是不可能的，只有按鈕事件會發生。使用JTabbedPane不可能修復選項卡的位置，這將導致這兩個「按鈕選項卡」在您選擇的佈局內浮動。在其左側插入更多製表符會導致始終以關閉和最小化按鈕結束製表符列表。
