问题 I'm making a sorting algorithm visualizer and i want the UI to update in real time to show how it works, step by step. But the UI only updates when the sort() method is done, I want it to update when updateHeight() is done the sort() method is initiated by an onAction @FXML public void sort() throws InterruptedException { minHeight = RectHeight[0]; counter = 0; minIndex = 0; temp = 0; for(int i=1;i<RectList.size();i++){ System.out.println(RectList.size()); System.out.println(counter); sort2()

问题 As far as I understand you can define "color variables" in the css. Let's say, I have a color called "default-background-color", and I set all backgrounds to be this color. -default-background-color: #d0d0d0; [...] .button{ -fx-background-color: -default-background-color } Then, during runtime, I want to change this color to be something else, so that all backgrounds change to my new color. How is this achieved without reloading a new css file? 回答1: You can change set the style

问题 Yet another binding issue from me. I already know that bindings are lazy, so they don't update when they don't need to, but this case is weird. The code below gives me the following output: minWidth calculation [150.0] minHeight calculation [150.0] minWidth calculation [0.0] minWidth calculation [0.0] minHeight calculation [0.0] minHeight calculation [0.0] It looks like Bindings.select() doesn't trigger binding calculation when when ClassTwo changes width or height . I think so, because when

问题 For some reason I keep getting an NPE in a gradle javafx project. My folder structure is very basic. I have a package with my java files in the main/java folder. I also have my resources in the main/resources folder. When I try to load image.png it gives me an NPE. public static Image createImage(Object context, String url) { Image m = null; InputStream str = null; URL _url = context.getClass().getResource(url); try { m = new Image(_url.getPath()); } catch (NullPointerException e) { e
