JavaFX 2.0 :: No Tooltip In Custom Control Allowed - Cannot Be Imported To SceneBuilder?
May 21, 2014
If I use an instance of Tooltip in my custom-control, it can not be imported to SceneBuilder any more. Using Tooltip in my custom-control skin works - is that the way it is supposed to be?
Background: I have a control (ValidatedTextField) which uses Tooltips to inform about unwanted characters. It works in SceneBuilder1.x.
SceneBuilder 2 does not "accept" this control unless I take out all Tooltips. I have verified this behavior with some other working controls.
I have found a workaround to use the Tooltip in the Skin.

Adding Node derived objects to SceneBuilder is easy and works fine.
I'm wondering how to add non-Node derived objects. It seems to be possible as MenuItem derived objects are listed and can be used.
How to add custom types (not Node derived) to SceneBuilder?

I'm trying to add a tooltip on a cell of a TableView in order to show some information to the user.
This is the code:
colonnaColore.setCellFactory(param -> {
TableCell<Appuntamento, Template> cell = new TableCell<Appuntamento, Template>() {
@Override
protected void updateItem(Template item, boolean empty) {
// calling super here is very important - don't
[Code] ....
In few words: there is a cell factory on the cell to show a colored box, then I added a tooltip to the cell. I need informations that are in the item added to the TableView that has type "Appuntamento". So I try to get my element with these code (that in others part of my code works); but here I get a Null Pointer Exception on cell.getTableView() and also on cell.getTableRow().
I'm probably using these methods in a way that was not expected.

When i press a button, i want to create a new object in my window(that i have created using scenbuilder, so i have a FXML file and a Controller class). In the window where i have a create button, there are also some textfields where you are supposed to enter name and date.
What i want to do is take the input from the TextField and store is temporally in a String variable, Its this strings i want to take the data from when i create a new object on my View. When i try to do something with the TextFields i get multiple errors that i dont understand at all.
I know my code may be very un-structured the absolute right way, i know, but i dont have time reconstructing and trying to understanding new patterns .The object is the circle and the vertical line.
TimelineMainView Controller
public class TimelineController{
StageClass sc = new StageClass();
NewTimelineController nt = new NewTimelineController();
[code]....

Unless I missed it, there does not seem to be a Spinner control in SceneBuilder.
Is this right?

I use SceneBuilder2.0 with JavaFX8 on OSX 10.9.4
When i use a stylesheet in SceneBuilder2.0 which uses a color-lookup the lookup fails with:
WARNING: Could not resolve 'abc' while resolving lookups for '-fx-background-color' from rule '*.button' in stylesheet supersimple.css
The color-definition is in the root-rule, so it should be found.
The lookup does work fine at Runtime.
There is a more complete description of the problem on stackoverflow:
javafx - SceneBuilder2.0 does apply rules with color-lookup - Stack Overflow

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.

In the SceneBuilder properties panels (part of Inspector pane) there are nice subheaders - separated by horizontal lines with a decent gradient in the background. I've tried to investigate the SceneBuilder source code at [URL] …, but I haven't found the proper file where this subheader is defined and styled.
I'd like to use similar subheaders in my app and why to reinvent the wheel...

When I assign a classpath-relative URL to an ImageView's 'Image' property, SceneBuilder is unable to display the Image in the Preview. It shows the text "Image not found" instead as a placeholder, which makes sense. What I'd like to do is add a classpath entry to SceneBuilder such that it is able to locate and display the Images. Any way to accomplish this (or similar)?

I have developed JavaFx application with playback option using JavaFx Media player and slider controls. I am updating slider value using javafx mediaplayer.currentTime().addListener() method by adding Change/Invalidate listener.
While playing MP4 video, slider values are not updating (Change/Invalidate listener not getting triggered while playing video) on Mac OS(version : 10.9.1). Below is the sample code snippet.
mediaPlayer.currentTimeProperty().addListener(new InvalidationListener() {
@Override
public void invalidated(javafx.beans.Observable o) {
updateSliderValue();
}

How can I set the default stylesheet for a user control that I have created? I want to make the control available for anyone to use and I want it to use a stylesheet by default without the user of the control having to do anything. I also want it to be possible for the user of the control to override the definitions set on the default stylesheet if he wants to.

TabPane and Pagination controls. However, I would like to be able to create a vertical toolbar that controls page or tab display.
Is it possible to create a Pagination with no page control? Or is my guess of sizing the Pagination control so that the lower section is off of the displayed window, thus hiding the page info? Or, is it possible to create a TabPane with panels, but no tabs?

I am fairly new to FX but well experienced with Swing. Since I am familiar with the Swing concept of rendering a let's say JTree I got problems with the FX model of - in this case - TreeView.
I read several documentations about FX. From the API doc of TreeItem I adapted the file browser example to create an own class like this :
public class PathTreeItem extends TreeItem<PathTreeItem> implements
Comparable<PathTreeItem> {
private boolean firstVisit = true;
private boolean readable;
private boolean dir;
private boolean symlink;
[Code] ...
But this did not change anything. I try to override toString() in both classes but even this did not change anything.
What I wonder so far:
Why is item in PathNodeTreeCell always null?What is the difference between the item I get in the updateItem method and the one I get from getItem() (line 10)How can I connect the PathTreeItem class to the PathNodeTreeCell classShould I always call super() in the constructors? (I delved a little bit in the sources of TreeItem and TreeCell and I found some setup code there )Is it ok to extend TreeItem in the way I does for my custom PathTreeItem class? ( I wonder if this is a cyclic dependency when I extends TreeItem in this way )How can I sort the nodes? I added the Comparable interface but this not change the sorting of the nodesAre ther some tutorials of TreeItem/TreeCell with no trivial objects like String ?
I want to adapt an well running Swing application to FX. In the Swing app I used a mechanism to load the child path's of a directory in a separate thread to avoid freezing if the UI if there are much child elements. I guess in FX I should use the Properties pattern to achieve this should I?

I created an ant script to create an installer for my JavaFx app:
<?xml version="1.0" encoding="UTF-8"?>
<project name="app-javafx" default="do-deploy" basedir="." xmlns:fx="javafx:com.sun.javafx.tools.ant">
<property name="java8.jdk.home" value="/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home" />
<property name="javafx.tools.ant.jar" value="${java8.jdk.home}/lib/ant-javafx.jar" />
<target name="init-fx-tasks">
[Code] ....
During compiling I see:
Using base JDK at:
/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk
Using default package resource [Bundle config file] (add package/macosx/Info.plist to the class path to customize)
Using default package resource [icon] (add package/macosx/app.icns to the class path to customize)
Creating app bundle: /Users/Utente/Documents/workspaceServer/javafx/target/deploy/bundles/app.app
Config files are saved to /var/folders/q6/vmt_h0tx3rgdbt_4h2_2f3780000gn/T/build6635061168386632777.fxbundler/macosx.
Use them to customize package.
fxbund
ler/macosx. Use them to customize package.
So I get files inside the temp directory and I copied them inside my project target directory. Unfortunally javafxbuilder don't use them to customize the package so I think the path where I have to put that files is wrong.

I have a VBox with 20 buttons and I have this style applied (menu.css) (only for VBox wrapper):
.button:focused {
-fx-background-color: #0768A9;
-fx-text-fill: #FFFFFF;
}
But when I pressed other button outside the VBox the style disappears, because the other button get the focus.
How I can do to keep the last button pressed with a custom style? (Only for buttons containing the VBox).

}
in MyNGRegion i override renderContent(Graphics g) for custom drawing
@Override
protected void renderContent(Graphics g) {
/* custom drawing */
}
The custom NGRegion gets drawn one time, but i want to continuously draw on every pulse.
i already tried a lot of things, but don't see how to do it properly:
using -Dprism.forcerepaint=true did not work.
overriding clearDirty() and set it

I did an implementation which is an extension of javafx.scene.control.ComboBox
Inside I imported the Class ComboBoxListViewSkin
import com.sun.javafx.scene.control.skin.ComboBoxListViewSkin;
I think this might be the reason as this comboBox is not recognized at the import to the scene builder library. I can show up the import dialog of custom controls, but my custom ComboBox is not showing up. All other implementations are there correctly as they are loaded from my customControl.jar file
I use the ComboBoxListViewSkin for the functionality to scroll to an item in the combo as a user types a letter on the keyboard.
I do this by:
/**
* This method scrolls the itemView of the items to the first item starting
* with the given char or string
*
* @param pressedKey
*/
public void scrollToChar(String pressedKey) {
String value = pressedKey.toUpperCase();
for (Object userEntry : getItems()) {
[Code] ....
I really need to show up my custom Combo in the scenebuilder, as otherwise the rest of my fxml is not editable in sceneBuilder 2.0 ....

<h:outputText value="#{it.get(newItem.strCampoNombre)}" rendered="#{newItem.strCampoTipo == '1' or newItem.strCampoTipo == '5' or newItem.strCampoTipo == '4' or newItem.strCampoTipo == '9' or newItem.strCampoTipo == '10' or newItem.strCampoTipo == '11'}" />

I am trying to run an example in which I pass a parameter to imported file but its not working.
This is my header.jspf file which I will include in a jsp file.
<img >
<br>${param.sub}
And This is the JSP file contact.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<body>
<c:import url="header.jspf">
<c:param name="sub" value="We love to hear from our clients------------" />
</c:import>
<br><br>
Now this is JSP page content
</body>
</html>
When I hit the contact.jsp file , It does show me the image I have on header.jspf , but its not able to print the parameter that I am setting in <c:param>
So after showing image it just shows ${param.sub}. So EL is not translated properly.

I was wondering what happens to the API packages I've imported at compile time. Are they compiled to classes and placed In the same file as the class containing the Import command ?
The reason I'm asking Is because I've noticed the src.zip file Is not In the JRE and since the JRE Is all that's needed to run an app , I'd like to understand what the import command does.

how java imports libraries from a jar file inside a source. Let's say I have the following code on Something.java file,
import com.mycomanyA.*;
import com.mycomanyB.*;
public class Something{
public static void main(String ... args){
// code goes here...
}
}
And the Something.java is inside the following structure...
A.jar
com/
mycompanyA/
A.class
Another.class
B.jar
com/
mycompanyB/
B.class
neededImage.gif
bin-folder/
org/
apache/
Something.java
To compile this code(Something.java) from command line I want to use the following command,
javac org/apache/Something.class
And for the compilation to be successful, I'll have to be just above bin-folder because...
- > Only then my default class path will be (.) and java would automatically include A.jar and B.jar(the other way is to add the jar files using -cp argument, which I want to avoid in this scenario)
- > And for the import org.mycompanyX to work I'll have to be in the (.) directory.
Are my assumptions correct about how java find jar contents imported in a source file?

In Chapter 9, you wrote a program named MeanMedian that allows a user to enter five integers and then displays the values, their mean, and their median. Now, modify the program to throw an exception if an entered value is not an integer.If an exception is thrown, display an appropriate message and allow the user to reenter the value. Save the file as MeanMedianHandleException.java.This is what I have. The exception is caught but the program starts over asking for five new entries.
import java.util.*;
public class MeanMedianHandleException {
public static void main(String[] args) {
int sum = 0, avg, mode;
final int MAX = 5;
int[] num = new int[5];
try {
Scanner keyboard = new Scanner(System.in);
for (int i = 0; i < MAX; ++i) {
System.out.println("Enter number ");
num[i] = keyboard.nextInt();
