问题 When user presses a button in my JavaFX2.2 UI, a dark blue halo appears to show it was clicked. During the course of events, my program may want to 'unclick' it to show it is no longer selected. I expected a button.setSelected(false); I remember Swing used to have this, but there isn't such a call in JavaFx. This article discusses drop shadows but I want to simply use the same appearance used when a button is clicked which isn't really a drop shadow. setEffect(new DropShadow()) Using setStyle

问题 I am working on a JavaFX 2.2 project and i want to set custom handling of the mouse (double) click event on a TreeItem. Using treeview.setOnMouseClicked i fire my code without errors but the problem is that the TreeItem, on every mouse double click, it toggles between expanded and collapsed. I suppose that this is the default behavior, but how i disable it?? 回答1: I had the same issue and solved it in time using EventDispatcher . class TreeMouseEventDispatcher implements EventDispatcher {

问题 I need to insert values in list view in one by one like chatting. now my code is @FXML private ListView<String> messageList; private ObservableList<String> messages = FXCollections.observableArrayList(); messageList.setItems(messages); 回答1: This may be similar to what you are asking.

问题 I want to create a controller based JavaFX GUI consisting of multiple controllers. The task I can't accomplish is to pass parameters from one Scene to another AND back. Or in other words: The MainController loads SubController's fxml, passes an object to SubController, switches the scene. There shall not be two open windows. After it's work is done, the SubController shall then switch the scene back to the MainController and pass some object back. This is where I fail. This question is very

问题 Simplified Problem: Make one Node "A" that is on top of another Node "B" to be half transparent to MouseEvents, so the Events will reach the underlying Node "B". Both Nodes are of equal size but Node "A" has a half transparent background image so one half of Node "B" is visible. Real Problem: I have a menu of tabs. Each tab can be dragged to expand the corresponding menu layer. Therefore each tab layer is a Pane with a partially transparent background (basically a polygon) of which the
