问题 I would like to display Mat objects from OpenCV directly with JavaFX. I have seen that it is possible to convert a Mat object into a BufferedImage . But as far as I know you can't display a BufferedImage with JavaFX, so another conversion would have to take place. Is there a way to directly convert it into a data structure that is displayable by JavaFX? 回答1: I have found a direct way to convert a Mat object to a JavaFX Image object. MatOfByte byteMat = new MatOfByte(); Highgui.imencode(".bmp"

问题 I am creating a reporting application in which I have 3 scenes with 3 controller classes.

I need to pass this one List from BatchProcesses_Controller to my MaintainanceBacklog_Controller . I am getting Caused by: java.lang.IllegalArgumentException: Can not set

问题 Intro I have to program a fat client using NetBeans Platform and JavaFX 11. One of the requirements is to offer a default and dark theme mode for the application. So if the user of my GUI application press the dark mode button, the application's GUI changes to the dark style. Problem While its obvious for me how to style the JFX components (via a CSS file), the CSS file doesn't has an impact on the NetBeans Platform's components like the menu bar. For instance the JavaFX components inside a

问题 I have a Maven JavaFX based desktop App and I have to convert it to a dynamic web app in eclipse or any other IDE ( I am using Eclipse Neon-Java EE).

问题 I would like to set the caret color for all JavaFX text inputs (e.g. TextField, TextArea, the ones in ComboBox:editable, DatePicker, etc...) I found this Stackoverflow answer: How to change the caret color in JavaFX 2.0? ... and an example on GitHub. The first one does change the text and the caret color which is not good. The second one extends the TextFieldSkin class, which is already better, but how can I use it in CSS? Any help is appreciated. UPDATE 1: I found the following CSS style
