问题 I am taking a GridPane example from an book. The book is not the most recent. When I try to use the Internet I keep getting Scene Builder which is not what I want to use.

So, our problem now is, that we want out pictures to get bigger, when the window is getting bigger also, but right now only the columns of the GridPane are getting more distance to each other. I tried to

问题 I have created JavaFX app with OpenJDK13 and OpenJFX13. In Eclipse I have made Runnable JAR but it doesn't work (at least on my Win 10 installation) unless I add VM arguments in command line. So, to fix this I made *.bat file with text: java -jar --module-path "C:\Java\javafx-sdk-13.0.1\lib" --add-modules javafx.controls,javafx.fxml Testing.jar It working that way. But, there is 2 things about my solution I would like to change. Is there any way to avoid Command prompt being shown when
