问题 I need that when I press the button to show me how many times was the button pressed. I use this method, but on console still show me the number 1.

问题 This question already has answers here : JavaFX FXML controller - constructor vs initialize method (3 answers) Closed 3 years ago . This is likely pilot error, but the FXML attribute is not binding to the controller class on fx:id. I've whittled it down to a trivial example, but still "no joy". What am I overlooking? FXML file... <?xml version="1.0" encoding="UTF-8"?> <?import javafx.scene.layout.AnchorPane?> <?import javafx.scene.layout.BorderPane?> <BorderPane fx:id="mainFrame" maxHeight="

问题 I am programming a JavFX UI on Java 8 where I create Buttons with sizes calculated at construction time. The problem is that the button's text (usually just a single letter in my case) sometimes is too big to fit in the button and then the button just stays blank. How can I set the font size for a JavaFX Button so that the text is not too high to not get displayed? 回答1: I found a solution. It's probably not very beautiful and I have no idea where the 0.45 come from (found it by trying), but

问题 I've created a GUI in JavaFX using SceneBuilder that works perfectly in windowed mode. It looks like this; What I would like to do is run the program maximised (not full screen) and ideally have the elements resize according to whether the stage is maximised or not. This is what the GUI looks like when the program is maximised; As you can see for some bizzare reason the table does "scale" however none of the other elements do. Is there a setting in SceneBuilder I can use that makes the
