问题 I've read through many questions on transparency and shadows, but I don't think I've seen this specific issue addressed. I'm able to successfully create a window with both transparency and a shadow, but I can't figure out how to make the color shadow not affect the transparency color. For example, the following code creates a window with a gray transparency and a red drop shadow. However, the red color affects the transparency of the main window as well, but I only want the shadow to extend

问题 I want to use an animated GIF in my project, but I dont know how I can stop the loop animation. I mean, I want the GIF to play 1 time only. Thanks! 回答1: I haven't done GIF animation, wasn't even aware that JavaFX would have methods for starting and stopping them. If you wish to do ANY animation using images, I rather suggest you do it frame by frame yourself. This way you have full control over it and you can have more than just 256 colors in your image. I read a very good article about

问题 I would like to know if it was possible to detect the double-click in JavaFX 2 ? and how ? I would like to make different event between a click and a double click. Thanks 回答1: Yes you can detect single, double even multiple clicks: myNode.setOnMouseClicked(new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent mouseEvent) { if(mouseEvent.getButton().equals(MouseButton.PRIMARY)){ if(mouseEvent.getClickCount() == 2){ System.out.println("Double clicked"); } } } }); MouseButton

问题 I have a JavaFx TableView . I'd like to allow the user to click and drag to reorder the table rows. I can't seem to find any way to do this, but it seems like a pretty common thing in GUIs. 回答1: Here is some code to re-order rows in a ListView by dragging the rows. Drag the birds to re-order them. Implementation for a TableView would be somewhat similar. import javafx.application.Application; import javafx.collections.*; import javafx.geometry.*; import javafx.scene.Scene; import javafx.scene

问题 I'd like to have Gecko, WebKit, or another webbrowser embedded in Java as a Swing/AWT control. I'm looking for something different than JRex or JWebPane . 回答1: You could use JxBrowser. It features a Swing/JavaFX component that wraps the Chromium engine while providing a rich API and out-of-the-box hardware-acceleration through the GPU. Unfortunately, they've dropped support for other engines (like Gecko and WebKit) since 4.0 version. Note that it's not free, except for open-source projects.

问题 I am trying to create a numeric TextField for Integers by using the TextFormatter of JavaFX 8. Solution with UnaryOperator: UnaryOperator<Change> integerFilter = change -> { String input = change.getText(); if (input.matches("[0-9]*")) { return change; } return null; }; myNumericField.setTextFormatter(new TextFormatter<String>(integerFilter)); Solution with IntegerStringConverter: myNumericField.setTextFormatter(new TextFormatter<>(new IntegerStringConverter())); Both solutions have their own

问题 As the javafxports Media is not yet implemented I'm looking to use the Android Native MediaPlayer instead. Does anyone know how to do this. 回答1: If you have a look at the GoNative sample here (docs and code), you'll find a way to add Android native code to your JavaFX project. This is a simple example of adding android.media.MediaPlayer to a JavaFX project using the Gluon plugin. Based on a Single View project, let's add first an interface with the required audio method signatures: public

问题 I want to use JavaFX properties for UI binding, but I don't want them in my model classes (see Using javafx.beans properties in model classes). My model classes have getters and setters, and I want to create properties based on those. For example, assuming an instance bean with methods String getName() and setName(String name) , I would write SimpleStringProperty property = new SimpleStringProperty(bean, "name") expecting that property.set("Foobar") would trigger a call to bean.setName . But
