问题 This question already has answers here : How to unmask a JavaFX PasswordField or properly mask a TextField? (5 answers) Closed 18 days ago . Im a student studying java and javafx, how do I show the password in the passwordfield using a checkbox? I am using gluon scenebuilder as my fxml editor 回答1: The duplicate is listed above for the correct but more complicated way of doing this. In this answer, I am showing two examples.

问题 The JavaFX docs state that a WebView is ready when Worker.State.SUCCEEDED is reached however, unless you wait a while (i.e. Animation , Transition , PauseTransition , etc.), a blank page is rendered. This suggests that there is an event which occurs inside the WebView readying it for a capture, but what is it? There's over 7,000 code snippets on GitHub which use SwingFXUtils.fromFXImage but most of them appear to be either unrelated to WebView , are interactive (human masks the race condition

问题 I am using openjdk11 + javafx11 on intellij Every time I try running a code that requires javafx, I get this error. After some googling around, it seems like it has to do with the display server (xorg, using archlinux kde 5). But I can't find anything that helps me fix the problem. If anyone could provide some insight to the solution, that would be delightful. Here's the output I get when I run it: /usr/lib/jvm/jdk-11.0.1/bin/java -Djava.library.path=/usr/lib/jvm/javafx-sdk-11.0.1/lib -

问题 I have a JavaFX using FontAwesome icons and I wanted to use the new version 5. But it seems it doesn't work anymore. Here's a simple demo app written in Groovy that works with the older FontAwesome version: import javafx.application.Application import javafx.scene.Scene import javafx.scene.control.Label import javafx.scene.layout.VBox import javafx.scene.text.Font import javafx.stage.Stage class App extends Application { static final String PENCIL = "\uf040" @Override void start(Stage

问题 Suppose you have an app that displays user graphic (some kind of image) then you want to allow the user to draw some lines on this image. I have the following questions regarding such situation: How would you accomplish that? How would you get pixel coordinates for the image from the user drag events? How would you update the image in real time? 回答1: I will give you an example of the exact opposite [erasing the Image on JavaFX] which I suppose will be enough as a starter point for you: import

问题 How do you create a video wall like in the JavaFX 2.0 demo here: https://www.youtube.com/watch?v=UXSmJYFrulY#t=411 For a start it doesn't have to be videos, it can be images as well. All I'd like to have is to place the nodes like they are in the video, i. e. in a curved shape like the insides of a cylinder or a sphere. Or is the source of that demo available somewhere? Thank you very much. 回答1: I researched and found a very awesome site with the relevant information: http://paulbourke.net

问题 I am using the accepted answer in this question: JavaFX Minimizing Undecorated Stage to minimize my app properly. However, unfortunately the default Windows minimize & maximize animations are not shown at all (the window just appears and disappears). I know it is possible to make the animations display with undecorated windows, since I have one application that has this behavior (PotPlayer). How could I make the animations appear with JNA? EDIT: Here's a working Kotlin code piece to minimize

问题 I develop one javafx application. In my application there are two scenes and one stage. In application the height and width for both scenes are same or constant. so as per my research the height and width for scene remain constant which mention in the constructor but the scene adjust itself with height and width of stage. when i lunch application with the height and width of stage which is different than the constant height and width of scene then scene adjust with stage. but when at the run
