我在JavaFX TableView中刷新行樣式有問題。JavaFX:如何刷新表格?
Java版本 「1.8.0_51」
的Java(TM)SE運行時環境(建立1.8.0_51-B16)
的HotSpot的Java(TM)服務器VM(25.51建設-B03,混合模式)
邏輯:
- 加載數據到的tableView。
- 通過setRowFactory將新樣式設置爲行。
- 將新數據加載到表中。
- 刷新新表格行的樣式。 (不適用於我)
如何重新加載行的樣式?

在你的代碼中,你將現在空的行設置爲純背景嗎? – scottb
button1.setOnAction - 僅設置2行,但3-4行的樣式不重新加載。 – stdex
我在您的代碼中看到您爲包含數據的行設置樣式,但我沒有看到您設置的行的位置已更改,因此它們不包含純數據樣式的數據。順便說一句,你爲什麼要調用recheck_table()這麼多?你只需要設置行工廠一次。 – scottb
