问题 There is no error but there is an issue with the plot am not getting the correct line chart plot, I want parameters in the x-axis and values in the y-axis but I have 3 engines as series but the series is not adding but the last series is only adding up. kindly help me with this issue. What I am trying to do is: Suppose I have n engines and m parameters of the engines, if I have 4 engines and 30 parameters then the total value will be n x m which is 4x30=120 so I want to plot engines in one

问题 I am building a application which can show live feed from my webcam. So I have been searching for sample codes as there was no webcam support in JavaFX and finally I found the code (javaFX+ OpenCV). But I am using fxml for my application and the sample code I found is a Non-Fxml. The following code is the sample code which I am not able to break it into FXML and its controller From here I find 2 ways 1:To break the non-fxml code 2:To use the non-fxml sample code in my application. So is it

问题 I'm really beginner with javaFX and probably I'm missing something, but here my issue: I should show some changes in my gui application sequentially. My code looks like this (each method performs a change in the gui, but the final result is given by the last method of course): public void updateGui() { Platform.runLater(() -> { doFirstStuff(); doSecondStuff(); doThirdStuff(); }); } It would be nice if between the execution of each method there was a little delay (1,2 or maybe 3 seconds) for

问题 I have just coded a simple example of using a scrolling pane in JavaFX. Just one ScrollPane placed in the Scene, and the ScrollPane holds a Label component with a large text. Using gradle I have uploaded the app on a Nexus 4 android device. As you can see from the video I have uploaded, the scrolling is way too slow. I am sure others have experienced this. Any suggestion of how this can be changed to the native speed scroll is really much appreciated. Source code of the app can be downloaded

问题 I'm using JavaFX to create a simple messenger client. The classes in question are: MainMenuController.class: this class handles JavaFX ui logic such as printing chat messages to text area Server.class: controls server socket and in/out logic Client.class: controls client socket and in/out logic I'm able to run the application perfectly on local host, except my program throws a nullpointerexception when I try to send messages too quickly. I'll past the relevant code, and then I'll explain what

问题 When running the program below, the TableCell is not applied (the numbers are left aligned instead of right aligned). Clicking on the "Change Values" button corrects the alignment.
