问题 My JavaFX TableView looks something like this: It would be so much more pleasing and efficient if the labels at the top were diagonal to save space. I imagine it like so: The goal is to make the column fit closely to the content despite a long header label. Can it be done? 来源： https://stackoverflow.com/questions/46164114/is-it-possible-to-make-diagonal-column-headers-in-javafx

问题 For some reason, my fx:id does not bind properly to my Controller class, and thus always causes an error. Controller package sample; import javafx.fxml.FXML; import java.awt.*; import java.awt.event.ActionEvent; public class Controller { @FXML public Button button; public void clickAction(ActionEvent actionEvent) { System.out.println("Button clicked."); } } FXML <?xml version="1.0" encoding="UTF-8"?> <?import javafx.scene.control.*?> <?import javafx.scene.layout.*?> <BorderPane fx:controller=

问题 How can I restrict the input from the user to only hexadecimal values? With decimal notation the range is from 0 to 16383, but I would like to let the user type an hexadecimal number into TextField . Therefore the range should be from 0x0000 to 0x3FFF . I have already built my GUI via SceneBuilder , therefore I just need a function to handle restriction and conversion on user's input. EDIT This is my version: startAddressField.textProperty().addListener((observable, oldValue, newValue) -> {

问题 I need to display the javafx tree table with values read from XML file. I am able to do it as shown below, I am able to add color to the combo box as shown But when I collapse the tree the color which is set still remains the same, as shown here How can I change it back to normal?

问题 I'm going fast to the point because I haven't a very fluent english, sorry. I'm learning javafx and I want when I click the X's windows after close it appear a warning. I know to do this in a button created by me in the middle of the windows, but I don't know how to control when the user press the X to close the programm.

问题 I have lots of fxml files containing different types of javafx nodes such as VBox, etc. I want to know if it is possible to add a stylesheet to the scene which automatically applies on all VBox elements declared any where in my project (or even created programatically).

However, I can't find anything similar solution for lots of node types such as VBox, HBox, and
