注：JavaFX的新手JavaFX的按鈕填充更改按鈕大小
一些文檔
Buttton.setPadding
所以每個人都知道是什麼填充，但here就是一個例子Android版澄清。
問題：
設置（和改變）上的javafx button填充增加本身之間的按鈕的大小，但不是「空間」和它的（相鄰的）鄰居。
更多信息：
我想有退出之間的空間和Reset按鈕。
假設：
Button btnExit = new Button("Exit");
填充通常是通過簡單的設置來完成：
btnExit.setPadding(new Insets(10)) //10 px "buffer" around button
或
btnExit.setPadding(new Insets(0, 10, 0, 0)) //10 px "buffer" on right only
我不這樣做將一個全能的填充，而是創造這個緩衝區，它放大了按鈕的大小。
無填充（btnExit.setPadding(new Insets(0));）
PADDING_LARGE=10
填充（btnReset.setPadding(new Insets(PADDING_LARGE));）
