我在JavaFX中的按钮上设置backgroundImage时遇到问题.
Image newGame = new Image("File:/CSS/nova_hra.png");
BackgroundImage newGameBgr = new BackgroundImage(newGame, null, null, null, null);
Button buttonNewGame = new Button("Nová Hra");
Button buttonLoadGame = new Button("Na?íst Hru");
Button buttonStatistics = new Button("Statistiky");
Button buttonExit = new Button("Konec");
buttonNewGame.setGraphic(new ImageView(newGame));
//buttonNewGame.setBackground(new Background(newGameBgr));
buttonExit.setMinHeight(40);
buttonLoadGame.setMinHeight(40);
buttonNewGame.setMinHeight(40);
buttonStatistics.setMinHeight(40);
buttonExit.setMinWidth(120);
buttonLoadGame.setMinWidth(120);
buttonNewGame.setMinWidth(120);
buttonStatistics.setMinWidth(120);
这对buttonNewGame没有任何作用.每次我尝试用这个加载图像
Image image = new Image(getClass().getResourceAsStream("a.png"));
我得到了runTime异常.我用的时候
Image image = new Image(getClass().getResourceAsStream("a.png"));
整个形象不顾一切.
