JavaFX 2.0 :: How To Force Layout Of Components
Mar 13, 2015
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);
[Code] .....

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?

Setting VM argument prism.verbose=true gives some insight of what happens.
There i see an old openGL version is used on OSX 10.9:
Graphics Vendor: ATI Technologies Inc.
Renderer: AMD Radeon HD 6630M OpenGL Engine
Version: 2.1 ATI-1.22.28
How do i force prism to a newer openGL version?

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.

1) Is it possible to have an item take up all the remaining space on a ToolBar?
2) Is it possible to align one or more items to the right side of a ToolBar?

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?
How can I enter latin letters with macron using keyboard layout that uses tilde deadkey?

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 my JSF2 app I have screens composed with :
- Header
- Body
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 ?
HeaderBean.java :
package com.omb.view;
import java.io.Serializable;
import java.util.List;
import javax.faces.event.ValueChangeEvent;
import javax.faces.model.SelectItem;

I have this code:
int[] X = new int[5];//X array declaration of 5 , might go higher to 10000~
for(int x_position=0;x_position<5;x_position++){//Starting X values
X[x_position]=1;
}
for(int x_value=1;x_value<=9;x_value++){
System.out.println();
for(int x_position=0;x_position<5;x_position++){
X[x_position]=x_value;
System.out.print("X["+x_position+"] = "+x_value+"; ");
[code]....
Each X[x_position] after a single cycle will be then put into char[x][y] at needed coordinates. x and y may have values from 9 to 4096;

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.

When I run the jar from cmd it works as it should but the results all go onto new lines so all formatting is lost and it looks.. ugly...
somehow make it so the console has a forced horizontal scrollbar but dunno how.

Really need some simple and complete example on how to extends components (graphically and functionally) for primefaces 5.
For example I can't figure how to add custom attributes to existing component or define default values for existing attributes.
Is there any tutorial or a basic common way to achieve this goal or each component have to be extended in its way?
