问题 how can I change default text "Done" under ProgressIndicator in JavaFX? 回答1: This is a little bit tricky but it is possible: In JavaFX 2.2 this is made like this: ProgressIndicator indicator = new ProgressIndicator(); ProgressIndicatorSkin indicatorSkin = new ProgressIndicatorSkin(indicator); final Text text = (Text) indicatorSkin.lookup(".percentage"); indicator.progressProperty().addListener(new ChangeListener<Number>() { @Override public void changed(ObservableValue<? extends Number> ov,

问题 I try to cancel user selection in a ListView according a condition. I tried to consume mouse clicked and mouse pressed event in ListView and ListCell but it didn't work. I don't understand why bu events occur after the selected item property change. How can I cancel the user selection? 回答1: If I understand correctly, you want to prevent users from selecting items by clicking on it. I further suppose that you tried a solution like this: listView.addEventHandler(MOUSE_CLICKED, click -> click

问题 I got JavaFX main thread, there I create new Thread that extends Task and sort and replace bars. Everyhing is good, but I want to make some delays(like 100ms) while replacing to show step by step sorting, maybe with animation. The problem is when I use Thread.sleep() or TranslateTransition() it just sum all delays miliseconds together in one big delay that happens before changing bars. How can I make delay that will work properly in UI thread? In main class: Sorting sorting = new Sorting();

问题 I'm working on a sudoku application but I'm having an issue which hinders my advancement. What I'm trying to do is to make this sudoku-board that I have created with loops, which adds a Label into a StackPane and that StackPane goes into it's designated spot into the GridPane. So I'm trying to force this board have a set size and not grow beyond that point. I've spent the whole evening researching and trying different things, for example putting the GridPane into an AnchorPane and trying to

问题 I was wondering if I can add a "layer" of colour on top of a column (cell background) without losing entirely the alternating row colours already present. I was using setStyle, and that just adds a solid colour. TableView<LineItem> table = new TableView<>(); table.getSelectionModel().setCellSelectionEnabled(true); TableColumn<LineItem, String> column1 = new TableColumn<>("Test1"); column1.setCellValueFactory(cellData -> cellData.getValue().string1Property()); column1.setEditable(true); table

问题 I have a simple two tab application build around JavaFXML and scenebuilder. The tabs do nothing at present because I cannot get past a nullpointer exception when trying to load them. The java and fxml files are arranged in a Netbeans project like this: Main Application: The application main class MainApp.java sets the scene and is declared as follows: package tabpane; import java.io.IOException; import java.util.logging.Level; import java.util.logging.Logger; import javafx.application

问题 although I'm just trying to install JabRef, I am quite surprised that this seemingly easy task is giving me so much trouble. I am using Windows 10 and I want to use JabRef (the most current version, which is 4.3.1). I do not have the JRE oder JDK for Java 8, but I have the Oracle Java 12 JDK. JabRef requires a JDK 8 but I cannot download it from Oracle without login. (And since they are quite nosy, I refuse to sign up to get the download.) So, I tried to use OpenJDK but that does not come

问题 .slider .track { -fx-pref-width: 300px; } .slider .axis-tick-label { -fx-text-fill: white; } My feeble attempts of writing CSS styles for the slider both don't work. I'm 100% sure my syntax is off. Any help? 回答1: You can do it by setting the -fx-pref-width attribute of slider and setting the -fx-tick-label-fill attribute of .slider .axis : .slider { -fx-pref-width: 300px; } .slider .axis { -fx-tick-label-fill: white; } Note: For vertical Slider , to affect the length of the track, you have to

问题 I'm using JavaFX, fxml, and css to display buttons with an image. When I change the size of the window, the image of the button nicely moves with the center of the button. I also want the image to scale up to, say, 80% of the button, but I can't figure out how to do that. A Java solution would be fine as well, if it can't be done in just fxml or css. The code is below, but I also made a repo with a MWE on GitHub. fxml <?import javafx.geometry.Insets?> <?import javafx.scene.layout.GridPane?> <
