问题 Does anyone know how to write a custom Event Dispatcher based on the javafx.event package? I searched in Google & Co. but didn't find a nice example. Have anyone a minimalistic example for me? That would be nice - I tried it a few times to understand it, but I failed. 回答1: The first thing to realize is how JavaFX dispatches events. When an Event is fired it has an associated EventTarget . If the target was in the scene-graph then the path of the Event starts at the Window and goes down the

问题 We are trying to count the number of rows in a TextArea Here are the TextArea properties PrefWidth 600 and PrefHeight 620 with MaxHeight 620 Wrap Text is set to true. We are using JavaFX 8 with Scene Builder We have a textPropertyListiner that will fire an Alert when the TextArea.getLength is greater than some value The issue with this method is it does not consider the user entering a carriage return \n So we implemented this code to capture the \n String toCount = txaDiaryEntry.getText();

问题 My goal for now is to make the animation of a little circle, going along the path of a big circle. In the future, I would need to dynamically change the speed of revolution using a slider, but that is not a problem now. I can't figure out how to make this animation smooth? By this I mean that I want my little circle to not slow down when it reaches the end of animation. Is this possible using path transition? Or should I use some other method to implement animation in order for it to be

问题 I am creating a mini-JavaFX project and wanted to use the Awesome Font Icon Pack.I loaded the fontawesomefx-8.9 using the Scenebuilder and opened the FXML in it and loaded two icons in it, also added the JAR file in External Libraries in IntelliJ but when I run the code it gives a ClassNotFoundException for de.jensd.fx.glyphs.fontawesome.FontAwesomeIconView.

ScaleTransition just stretch , do not set width... @Override public void start(Stage primaryStage) throws Exception{ Label label = new Label("->"); label.setStyle("-fx-text-fill: orange

问题 I'm trying to create a slideshow by taking an ArrayList of images and putting them into an ImageView using a for loop. However, in order to "pause" the program so that each image will be visible, I am trying to use Thread.sleep . This unfortunately hasn't had the desired effect. In trying to remedy this, my endless googling leads me to suspect that I should be using the Timeline class, but I have no idea how to implement it. Any help would be much appreciated. My dysfunctional code as it
