javafx

问题 Based on my experience the answer to the question in the Title is a resounding 'NO!!!', which I can't believe to be true ... but for my experience. I've created various property type interfaces having 3 methods, for example: getColor(), setColor(Paint c), and ObjectProperty colorProperty(). The get()/set() methods are implemented in the interface with the default modifier. This generally works fine except in cases involving Scene Builder and FXML. With Scene Builder the above property doesn't

问题 i'm fairly new to javafx and fxml. I'm trying to teach myself! However, when I was creating a program for a simple login GUI I came into an issue when I finally tried to run my program. It told me there was no main method in my class and I'm unsure of how to fix it. Any ideas? My program creates a login screen and when you enter "test" for the username and password it'll take you to another scene. Here is my Login.java package com; import javafx.application.Application; import javafx.fxml

问题 I have searched and googled a lot but can't find a simple solution to this. I want to resize the image according to its actual size and preserving the image ratio at the same time. As you can see from the following sample code, with the preserveRatio property set to true, I am able to resize the image. However, as I resize pass the actual width or height of the image, a white space will appear. How can I resize it without the appearance of the white space? package test; import javafx

问题 I've written a small javafx app that animates a square moving from the top-left corner to bottom-right. It then reverses the animation and runs it continuously. On my pixel 4 (xxhdpi) the square leaves behind a trail of edges on the return trip. This does not happen on on my Nexus 7 2013 (xhdpi) or on my desktop. Tried both the gluon plugin and also the gluon-vm plugin. Seems related to screen pixel density . . . how do you prevent the ghosting artifacts on dense screens? Image and code below

But when I added a statement which caused a NullPointerException the UncaughtExceptionHandler did not catch this exception. Why ? Is there another thread handling this exception? Or do I have to set the DefaultUncaughtExceptionHandler? I read JavaDocs: Uncaught exception handling is controlled first by the thread, then by the thread's
