问题 My Programm needs nine Countdowntimers. The timers are started by the user. In my implementation I create a timerclasses for each timer started. The timerclass uses a timeline. Depending on the start of the timers the seconds are asynchrone. I am not sure how to proceed. My first thought were to use only 1 timeline for all countdowns. I would put all stringProperties into a list and the timeline will change the property. I am not so sure if this is a good way? With some google I found out

问题 I am creating a JavaFX FXMl application with hibernate as ORM in Java. I want to read data from Excel and store it to MySQL using hibernate, but it fails to create Workbook.

问题 Thank you for your help. I've been trying to create a ribbon responsive layout like the one in Word, where the items resize one after another, and so far I haven't had much luck with it. custom_control.fxml <fx:root type="javafx.scene.layout.VBox" fx:id="dis" minHeight="-1.0" minWidth="-1.0" prefWidth="350.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2"> <GridPane fx:id="grid"> <children> <Button text="Button" GridPane.columnIndex="0" GridPane.rowIndex="0" />

问题 I'd like to create 2 independent windows at once. One window would be able to hold an observable list, the other one would show the selected listobject's properties. I'm trying to create the listview as a generic list, and combine it with an object specific window (eg. customer properties, beer properties, store properties). In short: if the user clicks 'Customers', it shows the listview with all the customers, and the first customer's properties are shown in a seperate, customer-specific

This works perfectly as desktop and

问题 I'd like to use the arrow/enter keys to traverse the cells in TableView , however, if I try to implement it in my custom EditCell class, it doesn't seem to work. Is there a way to make this happen? I've tried a listener on the TextField but it doesn't actually start the focus in the actual cell. Here is my code: Tester.java package tester; import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.TableCell; import javafx.scene.control.TableColumn; import
