是否可以替换调色板？

推荐答案

根据此解决方案，您可以在获得矩形及其颜色后替换调色板。

Based on this solution, you can replace the color palette once you get the rectangles and their colors.

例如，你可以使所有调色板更亮：

For instance, you can make brighter all the palette:

@Override public void start(Stage primaryStage) { ColorPicker picker = new ColorPicker(); StackPane root = new StackPane(picker); Scene scene = new Scene(root, 500, 400); primaryStage.setScene(scene); primaryStage.show(); picker.showingProperty().addListener((obs,b,b1)->{ if(b1){ PopupWindow popupWindow = getPopupWindow(); Node popup = popupWindow.getScene().getRoot().getChildrenUnmodifiable().get(0); popup.lookupAll(".color-rect").stream() .forEach(rect->{ Color c = (Color)((Rectangle)rect).getFill(); // Replace with your custom color ((Rectangle)rect).setFill(c.brighter()); }); } }); } private PopupWindow getPopupWindow() { @SuppressWarnings("deprecation") final Iterator<Window> windows = Window.impl_getWindows(); while (windows.hasNext()) { final Window window = windows.next(); if (window instanceof PopupWindow) { return (PopupWindow)window; } } return null; }
