Problem Scenario:In the previous article, we hid the window's default title bar, causing the mouse to click on the form to not be dragged.Ideas:Adds a mouse-down event Listener and Mouse drag event listener to the component.Realize:　　Code snippet:Private double xoffset = 0;Private double yoffset = 0;Code snippet:Root.setonmousepressed (MouseEvent event), {Event.consume ();Xoffset = Event.getscenex ();Yoffset = Event.getsceney ();});Root.setonmousedragged (MouseEvent event), {Event.consume ();St

1. For the onaction event of the button, define the method in the fxml file: onaction = "# processlogin" In its corresponding controller, the signature of the method is: @ fxml protected void processlogin (actionevent event) [or private] However, if it is another event type, the general format is: Define the method in the fxml file: onmouseclicked = "# handlewinclose" The corresponding method signature is: @ fxml private void handlewinclose (mouseevent event) [or protected] 2. The public void i

For an enumeration class, we want to store a meaningful English string in the database and display a meaningful Chinese string on the interface. So set two properties for the enumeration class, such as the following Datastatusenum (data State enumeration):package com.lirong.javafx.demo.j3003;/** * In Datastatusenum, code is used to persist to the database, and value is used to display on the interface. There are four enumeration values. Test class: Package Com.lirong.javafx.demo.j3003;import Ja

than n , i.e.: 0 . 2. System.currenttimemillis () It returns the number of milliseconds that have elapsed since UTC 1970 1 months , 1 days, and midnight. 3. The seed used by the new Random () construction method is the current system.currenttimemillis () ,so the above code:Random rand = new Random (System.currenttimemillis ()); can be shortened to Random rand = new Random (); 4. Group root = new Group (); can be changed into Pane Pane = new Pane ();This article is from the "Fengbin Technolog

In this article, we are concerned with the Bluebill mobile class, especially the controller that manages the logic behind all search species screens, so this article helps you understand JavaFX's language performance. And we will cite some examples to illustrate the techniques to be introduced and the pitfalls of a typical JAVAFX structure. The author wants to embed an updated screen in the application. Video playback requires the use of quciktime.

BackgroundIn JavaFX, menus can be scrolled when MenuBar's menu or its sub-menu contains more than the MenuItem a screen can display. There is a bug where scrolling is recorded, and all ContextMenu at the same level use the same scroll position, which means that when you scroll down more than a few distances in a contextmenu, Another contextmenu may not be able to see ContextMenu at all.AnalysisThe root cause of this bug is that different ContextMenu s

In the JavaFX actually does not have the traditional meaning the array, the correct name should be the sequence, namely sequence, it resembles the traditional language storehouse inside ArrayList, does not have the length limit, may add the element or deletes the element at any time, but also provides some additional operations. 1. Define an array Place the elements in square brackets and separate them with commas to define them. VarweekDays = ["Mo

Controllersfx: controller public class MyController { public void handleButtonAction(ActionEvent event) { System.out.println("You clicked me!"); }}Of course, the Controllers class can also implement the Initializable interface so that the initialization method initialize () can be called during loading ()
