问题 I am trying to practice my binding. I want to make a window with two spinners and just get them to show the same value. The problem is that the binding is unreliable: the spinners seem to stop updating each other if they are clicked too fast. Both spinners still respond to clicking, and clicks are counted correctly on the spinner being clicked, but the other spinner stops updating and never recovers. And it doesn’t have to be very fast clicking at all to cause it. My code is based on this

问题 What is the formula for deciding if an rgb code is green? Here is an attempt: public boolean isGreen(Color color){ return (color.getGreen() > 0.8*(color.getBlue()) && color.getBlue() > color.getRed()); } That is, return true if the green value of rgb is considerably greater than the blue, and the blue is greater than the red. A test was conducted on its accuracy. Methods: A JavaFX program generated 132 orbs every 6 seconds, each with an rgba (alpha is irrelevant in this case) value of (Math

问题 In JavaFX 2, I want to disable a some cells in a column for edition. Something along the lines of TableModel.isCellEditable(row, col) in Swing. I need the item in the row to make a decision whether the cell is editable, cell value is not enough. The code I managed to write is: TableView<FilterItem> localTableView = new TableView<FilterItem>() { public void edit(int paramInt, TableColumn<FilterItem, ?> paramTableColumn) { if (paramInt >= 0) { FilterItem item = getItems().get(paramInt); //get

So this is my controller class @FXML private ChoiceBox<String> genre; @FXML private ChoiceBox<String> branch; @FXML private ChoiceBox<String> status; @FXML private ChoiceBox<String> company; @FXML private ListView
