I noticed that when building a UI programmatically in several steps the width/height of the Pane I use for layout is -1/-1. I read that this is the case until the actual rendering happens. Is there a way to force that earlier? Suppose I wanted to size other UI components (which are not visible initially) according to the size of another pane. How do I do that? Binding the properties does not do the job in the case that those components are not necessarily visible at the same time. Is there a trick to achieve that?
I have quite a specific view for how I want my components layed out. No matter what I try I can get them to display how I want! I'm using three JPanels. There's a main panel that goes inside the tabbed pane. This main panel contains two other panels. The First panel is a gridbaglayout panel, with labels on the left column, and components on the right column. The second panel is underneath the second, and contains a label, and a button beneath it. THis uses a basic box layout, with one component per line. The label doesn't always appear (depends if a component is changed). With everything showing, this is how it looks so far:
However, I want the Labels on the left of the pane. The right hand column should be aligned horizontally and have more space from the labels. Ideally I'd like a gap between the last label/checkbox and the Note label.
This is my current code for the panel/s inside the tabbed pane window.
videoPanel = new JPanel(); applyVidBtn = new JButton("Apply Settings"); applyVidBtn.setVisible(false); warningLbl = new JLabel("Note. Applying these settings causes a program restart."); warningLbl.setVisible(false);
In other words in a table view with several editable columns, when a new row is added this row does not contain any column cells yet. Cells are added on demand once a column gains focus and starts editing. Is this the case? Is there any way to force the row to construct all cells eagerly?
I am wondering how one rearranges an existing complex UI using scene builder. I have tried, for example, to add a scrollpane around another pane that was already nested deep in my layout and did not find a way to do this. Is this not supported or am I just not getting how it's done? Typical practical examples of this would be that one introduces a split pane around an existing part of the layout and moves existing controls/panes including all their configuration (resource keys, bindings etc.) into one part of the split pane to add more functionality into another.
I have a stage,it has two layers scene, if user click the button,then change to another layer, and also can change back. It just like swing cardlayout. How can i implement cardlayout in JAVAFX?
I can not enter Latin letters with macron (Latvian specific characters) in JavaFX programs. Instead something like Latin letters with acute are entered.
what I need to enter is characters like this: Latin letter "a" with macron
Browser Test Page for Unicode Character 'LATIN SMALL LETTER A WITH MACRON' (U+0101)
what is actually entered: Latin letter "a" with acute
Browser Test Page for Unicode Character 'LATIN SMALL LETTER A WITH ACUTE' (U+00E1)
There are several keyboard layouts available for Latvian language input. Problem persists only on Windows OS for layouts using tilde key or apostrophe key as deadkeys. There are no problems with Microsoft Latvian (QWERTY) layout that uses ALTGR key as deadkey. There are also no problems on Linux OS using keyboard layouts that causes problems in Windows OS. I also noticed that character input works as expected int SceneBuilder 2.0 (I believe it has been build with javaFX). There are no problems also in java Swing GUI framework. So could this be a bug in JavaFX or am I missing some configuration settings?

No problem setting background color for layouts, e.g. bdrPn.setBackground(new Background((new BackgroundFill(Color.BLACK, CornerRadii.EMPTY, Insets.EMPTY))));
But neither of the following are working for me, running JavaFX 8 on latest OS-X
scene = new Scene(bdrPn, winW, winH, Color.BLACK); scene.setFill(Color.BLACK); scene.setFill() worked fine for previous versions of JavaFX.
In the header I have a combo list. At each change in value in the combo list I have an Ajax request that updates the data in the Body. So far everything is working properly. Now the home screen's structure should be change when the value of combo list change. To do this I have :
- 1 ManagedBean HomeBean that manage the home - 1 ManagedBean HeaderBean that manage the header - 2 object HomeScreen1.java and HomeScreen2.java that allows me to valued data from each screen - 2 services HomeScreen1Loader.java and HomeScreen2Loader.java that manage loading of each type of screen - 1 template home.xhtml - 2 fichier home1.xhtml et home2.xhtml
When I log in to the application, I get the good page corresponding (Element type 1 => home page 1). But when I select a type 2 item, the actionListener methode is execute, ManagedBean's data was updated (for type 2 screen) , but the page does not updated. What do you do ?
Whether it is possible to force the installation of JRE when trying to open JNLP file. It is quite often case when users try to run JWS application without JRE installed. The best option would be to force the installation or at least display some message with instructions. Perhaps there are different ways to handle this problem.
I'm a beginner fiddling around classes in Java. I noticed on this particular code, Eclipse will give me an error and suggest I put the static keyword in front of the variable.
public class test { //the following line is where Eclipse puts the static keyword static FileAccess hello = new FileAccess("D:" + '\', ".mp3"); public static void main(String[] args) { for (int i = 0; i < hello.getTotalNumberOfFiles(); i++) {
[Code] .....
The FileAccess class is just a class I made while trying to retrieve filenames from my hard drive.
As far as I can tell, it works correctly after I put the static keyword there. I just want to know why it is required in this particular code, considering it didn't need to do that when I made a simpler class while I was getting my feet wet at creating classes in Java.
We've implemented the Whitelist and there's an application I need to use the Force attribute with, however, I'm unable to get this to work. As I read it, this code says use Java 1.6_24 for Example.com and any other applications are blocked from running. There are three versions of Java installed - 1.6_24, 1.7_65 & 1.8_25. The Java console shows 1.8_25 being called.
Here's the ruleset.
<ruleset version="1.1+"> <rule> <id location=https://example.com /> <action permission="run" version="1.6_24" force="true" /> </rule> <rule> <id /> <action permission="block"> <message> This application is blocked due to Java restrictions, please contact the Service Desk for assistance.</message> </action> </rule></ruleset>
I also tried
<action force="true" permission="run" version="1.6.0_24" /> and also <action force="true" version="1.6.0_24" permission="run" />.
The Java console is still showing version 1.8.0_25.
How to force browser to open/save/save as the file from server instead of browser cache.
I am creating a csv file through a pl/sql procedure and forwarding the link to user once user clicks on link he downloads the file, however if the same thing is repeated then browser returns the old cached file instead of new file generated on server.
I decide to make a new GUI just for fun and practise and i want to learn more about Layouts.. right know i am try to understand some staff about GridBagLayout.
I want to make a GUI with this Layout :
So..first i am a frame with borderlayout then i put a JMenuBar and bla bla bla and i create panel with GridLayout which i put on myFrame.add(panel1,BorderLayout.WEST) and also i make an another JPanel which i put of the Center of main Frame (myFrame.add(panel2,BorderLayout.Center))
when i run the program i get this GUI :
Now the problem is that i can't put the JButton on the top of the gridLayout just to look like the first picture.. i Read about anchor and i try to
gbc.anchor = GridBagConstraints.NORTH; but without results.. still the components are on the middle of the JPanel..
I know my problem is my lack of understanding of OOP but I have searched for a solution and can't even seem to get close.This is a very simplified version of what I will need to do. I have a button and six textboxes. When the button is pressed I want to take the text from textbox6 and place it in textbox1, textbox2, textbox3, textbox4, and textbox5.
I need sometthing better then this brut force method.Java Code:
package textboxes; public class TextBoxesGUI extends javax.swing.JFrame { public String NewText; public TextBoxesGUI() { initComponents();
I want to make a simple Table Tennis game. I have 2 drawing classes. 1st should draw oval and 2nd rectangle. But second class, which should draw rectangle doesn't work and if i use it together with oval class, then oval doesn't appear too.
Java Code:
public static void main(String[] args) throws InterruptedException { Intro i = new Intro(); Pall pall = new Pall(); Laud laud = new Laud(); i.frameID().add(pall); // this adds oval i.frameID().add(laud); // this adds rectangle i.frameID().pack(); i.frameID().setSize(400, 400);
