python桌面开发吐血_想用java写个桌面小demo，就布局都差点写吐血了，学艺不精...
demo簡略需求
項目背景
很多文件重復存放，除了管理混亂，還會對患有強迫癥用戶的身心造成10000點的傷害...其實就是360云盤當時上傳了有上傳，造成很多重復的圖片+視頻，前陣子360個人云盤“倒閉”，電腦日夜兼程，始終把圖片下了下來，下下來后，作為重度強迫癥患者的我，看著無數張圖片里面n多重復文件，吃不香睡不著....
點擊“載入”，默認載入上次目錄，若是第一次，默認載入文檔圖片目錄，同時彈出“選擇路徑”菜單。選擇需要載入的文件目錄后，如果跟現載入的不一樣，則中斷載入操作，重新載入新路徑。若一樣，則繼續載入；
圖片預覽，默認顯示第一張，如果用戶點擊選擇某一張，則圖片預覽變為用戶選中的；
點擊去重，彈出“重速度”(多線程)，“重性能”(單線程)
點擊撤銷，恢復去重時刪除的文件
去重：先判斷文件名(除去“ - 副本”、“(1)”之類結尾的字符)是否重復，再判斷文件大小+文件類型是否一樣，如果都一樣，則計算文件的md5值，通過md5值來判斷。
第一次啟動時，彈出倒計時框，提示去重撤銷需要創建一個隱藏文件，如果不需要撤銷，可以打鉤，不創建隱藏文件，而是直接刪除；
彈出免責聲明，數據無價，請確認再去重(刪除)。
UI樣圖，如下圖

想用java寫個桌面小demo，就布局都差點寫吐血了，最終還是沒學好，哎，都怪學藝不精
