Control insets in JavaFX 2.2

With JavaFX 8 the control has a property holding the padding. How can I retrieve the insets with JavaFX 2.2? I need them to calculate the content area. If I do not take them into account, they are ignored, which is not what I intend to do.

Only things that inherit from Region have a getInsets() and a getPadding() method. Except for that, the usage of the Insets class is limited.
It works in FX8 because they changed the inheritance tree of the controls.
i.e:
in JavaFX 2.2, controls did not inherit from Region:
java.lang.Object
javafx.scene.Node
javafx.scene.Parent
javafx.scene.control.Control
javafx.scene.control.Labeled
javafx.scene.control.ButtonBase
javafx.scene.control.CheckBox
In JavaFX 8, they do inherit from Region:
java.lang.Object
javafx.scene.Node
javafx.scene.Parent
javafx.scene.layout.Region
javafx.scene.control.Control
javafx.scene.control.Labeled
javafx.scene.control.ButtonBase
javafx.scene.control.CheckBox

Setting styleable properties & pseudo-class state to controls in JavaFX 2.2

Hi All,
Greetings!
Can anyone please let me know how to create or set styleable and pseudo-class state properties for custom controls developed with JavaFX 2.2.
I found a very nice wiki regarding this. (https://wikis.oracle.com/display/OpenJDK/CSS+API+to+support+custom+UI+Controls)
But this seems to be with JavaFX 8 version. As i cannot find PseudoClass in the current version of JavaFX 2.2.
Thanks & Regards,
Sai Pradeep Dandem.

There is no public API in 2.2 for adding adding styleable properties and pseudo-class state to controls in JavaFX 2.2.
The implementation between 2.2 and 8.0 changed significantly in terms of API, class names, etc. The model is roughly the same, but if you implement something in 2.2 using the private implementation APIs, it will not work, and may not even compile, in 8.0.
// A pseudo-class in 2.2
    private BooleanProperty foo = new BooleanPropertyBase() {
                @Override
                protected void invalidated() {
                    impl_pseudoClassStateChanged("foo");
                @Override
                public Object getBean() {

                    return "foo";

How can I select multiple cells in tableview with javafx only by mouse?

I have an application with a tableview in javafx and i want to select multiple cells only by mouse (something like the selection which exists in excel).I tried with setOnMouseDragged but i cant'n do something because the selection returns only the cell from where the selection started.Can someone help me?

For mouse drag events to propagate to nodes other than the node in which the drag initiated, you need to activate a "full press-drag-release gesture" by calling startFullDrag(...) on the initial node. (See the Javadocs for MouseEvent and MouseDragEvent for details.) Then you can register for MouseDragEvents on the table cells in order to receive and process those events.
Here's a simple example: the UI is not supposed to be ideal but it will give you the idea.

JavaFX: TableView's cellvalue is not enough to display in columns, I want..

javaFX: TableView's cellvalue is not enough to display in columns, it will be clipped end of '...', how to show a tip on such cell?
I need a tip because sometimes i can't drag the colunm's head. So i can't see the whole content of the cell.

Create a custom cell and overwrite the updateItem method. Add a tooltip:
                   Tooltip tip = new Tooltip(getString());
                   Tooltip.install(this, tip);

JavaFX table view headers bug?

Hi,
I created simple application with table view and I have problem with the way that table view headers are displaying.
When table view is not focused headers are improper width but when table get focus then headers width is changing and everything is working as expected.
Before table view get focus:

You should run this app without problems becouse it is embeded SQLLite databse. Look into SqlLiteDB class. You can even delete database.db file becouse sqllite driver will automatically create database.

Thanks PhiLho
Well ,after i configured my NVIDIA graphics card's CPanel
I select "Let the 3d application decide" which had solved this problem.
Actually i had selected "Use my preference emphasizing : Quality" before so i got bad graphic i think.
Any way it's solved ..
and one more confusion If you don't mind telling what's the use of Point3D in javafx 1.3?

Netbeans 7.2 - JavaFX Tutorial - problems with imports

I am indeed a newbie. I installed Netbeans 7.2 and created a JavaFX Application project while following a tutorial. I inserted code (as instructed) for a GridPane with alignment and inset adjustments. After inserting the GridPane code from the tutorial, my build got errors (undefined for pos.Center and Insets
        GridPane grid = new GridPane();
        grid.setAlignment(Pos.CENTER);
        grid.setHgap(10);
        grid.setVgap(10);
        grid.setPadding(new Insets(25, 25, 25, 25));
        Scene scene = new Scene(grid, 300, 275);
        primaryStage.setScene(scene);
{code}
It took quite a long time for me to discover what includes to code in order to solve these build errors. I eventually ended up with :
{code}
package login;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.text.Text;
import javafx.scene.text.Font;
import javafx.geometry.Insets;
import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.PasswordField;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.HBox;
import javafx.scene.paint.Color;
import javafx.scene.text.Font;
import javafx.scene.text.FontWeight;
import javafx.scene.text.Text;
{code}
The wizard produced these includes at the start:
{code}
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
{code}
My questions:
Is there a way to specify the includes for javaFX with
{code}
javafx.*;
{code}
Is there a simple way in Netbeans 7.2 to find out what include to use to solve the undefined build errors?

I am not a Netbeans user but I think this is what you are looking for.

How to add 3 legends for a single series barchart?? JAVAFX

Here is my code to generate 10 bars of different colors. I want to add legend respectively but it only one shows yellow legend
1. I think it shows only 1 color because there is only 1 series. Is it possible to add more than 1 legend for a single series?
or
2. or can i display another image for legend in barchart??

Either:
1. Use a chart which displays multiple series, then you can allow the built-in legend to show OR
2. Use a single dynamically colored series have you have done and create your own custom legend.

Drawing and some layout help for a simple control: thin lines and application start

I am trying to create a new, simple control. The control should act as a grouping marker much like that found in the Mathematica notebook interface. It is designed to sit to the right of a node and draw a simple bracket. The look of the bracket changes depending on whether the node is logically marked open or closed.
After looking at some blogs and searching, I tried setting the snapToPixels to true in the container holding the marker control as well as the strokewidth but I am still finding that the bracket line is too thick. I am trying to draw a thin line. Also, I am unable to get the layout to work when the test application is first opened. One of the outer brackets is cut-off. I hardcoded some numbers into the skin just to get something to work.
Is there a better way to implement this control?
How can I get the fine line drawn as well as the layout correct at application start?

The test interfaces are already defined for you - the 3rd party session bean remote/local interfaces.
It is pretty trivial to create implementations of those interfaces to return the test data from your XML files.
There are a number of ways to handle the switching, if you have used the service locator pattern, then I would personally slot the logic in to the service locator, to either look up the 3rd party bean or return a POJO test implementation of the interface according to configuration.
Without the service locator, you are forced to do a little more work, you will have to implement your own test session beans to the same interfaces as the 3rd party session beans.
You can then either deploy them instead of the 3rd party beans or you can deploy both the test and the 3rd party beans under different JNDI names,and use ejb-ref tags and allow you to switch between test and real versions by changing the ejb-link value.
Hope this helps.

Problem with custom control and focus

I've a problem with the focus in a custom control that contains a TextField and some custom nodes.
If i create a form with some of these custom controls i'm not able to navigate through these fields by using the TAB key.
I've implemented a KeyEvent listener on the custom control and was able to grab the focus and forward it to the embedded TextField by calling requestFocus() on the TextField but the problem is that the TextField won't get rid of the focus anymore. Means if i press TAB the first embedded TextField will get the focus, after pressing TAB again the embedded TextField in the next custom control will get the focus AND the former focused TextField still got the focus!?
So i'm not able to remove the focus from an embeded TextField.
Any idea how to do this ?

Here you go, it contains the control, skin and behavior of the custom control, the css file and a test file that shows the problem...

Remaining questions while evaluating JavaFX for a new project

Dear forum members:
currently I am evaluating the possibilities of next-generation GUI technologies, such as JavaFX, Silverlight and Flash/Flex, for a new project. To get a basic understanding of JavaFX's concepts, I worked through the available online text and video tutorials, and all the treated topics seem quite obvious/comprehensible to me +as long as one is only confronted to relatively static GUI component hierarchies+. But, as a newbie, some questions concerning more dynamically defined GUIs (i.e. dynamic JFX scripting*) still remain.
Application scenario (exemplary):
Say I want to create a "Online Shopping Application" that supports "+ShopOwners+" in *dynamically* defining the "+Shop Model+" structure, e.g. accepted visitor (client) categories, product categories their products, pricing information, payment methods, etc.
Then, based on the dynamically defined model, the shop owner should be able to design and layout the necessary forms, such as order forms, survey/feedback forms, etc. This should be done in "design mode", and there should also exist a possibility for him/her to preview the specification results in a "preview mode".
Finally, the shop owner must be able to save the model and forms on the server side in a way that can requested and run be the shopping app end users (the shop clients) via (another (?)) JavaFX frontend.
_The still remaining questions for this scenario are:_
+1. Is JavaFX appropriate for creating such kind of applications, especially when it comes to dynamic JFX scripting (and compilation) on the client side??? (By now I'm not quite sure if this is really necessary for my plans!)+
+2. Concerning the ShopOwner's GUI with its design and preview mode (and knowing that the latter mode will be the GUI version presented to the shop clients in another JFX module):+
+Is it possible to *dynamically *build up a +Scene Graph+ in a way that lets me handle and *compile* the corresponding +JFX Script+ on the client side for previewing it? Or is a client-server roundtrip absolutely necessary?
How could one persist this JFX Script on the server side? I.e., which intermediary format would be the most appropriate? => XML, JSON, JFX Script?
3. Concerning the "Shop Model", would I optimally create JFX classes or even Java Beans to bind to?
4. And finally: What would be your recommended way (software architecture) to fulfill this task in JavaFX?
Do there already exist some JFX components (dynamic forms/survey authoring modules, etc.) that persue a similar task and that I didn't find yet?
As the clarification of the above-mentioned issues are very important for me, I hope that you more experienced users can help me, pointing me to a practicable approach.
Thank you very much for any help and constructive tips in advance.
Best regards
Martin Meyers

Q1: Do I optimally need 2 different custom components for each treated concept, or do I have just 1 component with 2 internal modes (design & preview/usage)??
E.g., (a) FormSpec widget composed of LabelSpec, TextBoxSpec, ChooseBoxSpec,... widgets each having their preview pendants
Form, Label, TextBox, ChooseBox, etc.
versus
+(b) only Form widget composed of Label, TextBox, ChooseBox widgets, but all having a "design/preview execution mode".+
Closer to (b), I think, though each widget doesn't need to be modified to have design and preview modes. Instead, each widget can be wrapped within a Group to provide the design/preview functions without modifying the widget itself.
The technique is as follows. Given a sequence of widgets (Nodes, really), for each widget, wrap it in a Group that contains that widget but with an overlay Rectangle in front of it. The Rectangle can be semi-transparent, or fully transparent if you prefer. (In the example below I've made it a semitransparent color to make its location obvious as well as to provide a highlight that signals design mode.) The overlay Rectangle is set up so that its dimensions will exactly track the dimensions (bounds) of the widget behind it. I've set blocksMouse to true so that when it's present, the overlay traps events and prevents interaction with the widget. There is a boolean variable previewMode, controlled by a CheckBox, that controls the visibility of these overlay rectangles. I've also added a bit of code to track mouse events on the overlay rectangles so that you can move the widgets around when you're in design mode.
Note that the visible variable differs from transparent, i.e. opacity == 0.0. If a node is visible but is transparent, it is still eligible to receive events; whereas if visible is false, it does not receive events.
Here's some code that illustrates this technique. I'll answer your other questions in a subsequent post.

Java run time error while executing JavaFX code

Hi
I copied the code from [http://java.sun.com/javafx/1/tutorials/ui/overview/UIControls.fx|http://java.sun.com/javafx/1/tutorials/ui/overview/UIControls.fx] while
reading in [http://java.sun.com/javafx/1/tutorials/ui/overview/#controls|http://java.sun.com/javafx/1/tutorials/ui/overview/#controls] tutorial and paste it to my
netbeans editor but i got following error.

BUILD FAILED (total time: 18 seconds)can anyone tell whether its netbeans fault or javaFX. I am using netbeans 6.5.1 on windows vista. I have added following plugin in netbeans for javaFX
*JavaFX Kit
*JavaFX SDK for Windows
is anyone also getting this error for this code and have solution for this.

You are correct the crash is causing due to ToggleButton and ProgessBar. the code is correct because i tried it on eclipse 3.4 and it worked fine.This is definitely netbeans error. because its giving error even if u try to execute javafx code with just one ToggleButton or ProgressBar. I tried the following simple code in netbeans 6.5
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.control.ToggleButton;
import javafx.scene.control.ProgressBar;
var toggle=ToggleButton {
                translateX:50
                translateY:50
                text: "First"
                width:100
                height:20
var progress= ProgressBar {
        progress: bind ProgressBar.computeProgress( 100, 30 )
Stage {
    title : "Toggle Button Test"
    scene: Scene {
        width: 200
        height: 200
        content: [ toggle
} When i just added toggle button to contents then button showed up in window but on clicking it window disappear and compiler gave crash error on the other hand when i added just progess bar it just throws the error.The same code is running fine on eclipse
Is there any workaround in netbeans for this if its a bug and if not what should i do to correct it.

Variable binding with javafx.ext.swing.SwingSlider

My first javafx program consists of a slider and a text box, the text box displays the current value of the slider. The problem is the text box does not display anything when the program just starts up, but only gets populated once I change the value of the slider. I am not sure what I am doing wrong. Here is the code:
import javafx.scene.control.*;
import javafx.scene.*;
import javafx.stage.*;
import javafx.ext.swing.*;
import javafx.scene.layout.*;
var BPMSlider = SwingSlider {
    minimum: 10
    maximum: 250
    value: 60
}; //BPMSlider
var BPM = bind "{BPMSlider.value}";
var BPMDisplay = TextBox {
     text: bind BPM
    columns: 3
}; //BPMDisplay;
Stage {
    title: "Slider";
    width: 1000
    height: 500
    visible: true
   // Set the scene
   scene:
       Scene {
       content:
           HBox{ spacing: 10 content:[ BPMSlider, BPMDisplay ] }
       } // Scene
}Thanks!

Hi,
I don't know how to solve it with binding values, but I managed to solve it with temporary int value which contains Slider.value.
If any one can help us with solving this binding value we are waiting for answer.
Here is the code:
package slider;
import javafx.ext.swing.*;
import javafx.scene.*;
import javafx.scene.control.*;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.*;
import javafx.stage.*;
var tempSliderVal:Integer = 60; // temp BPMSlider value
var BPMSlider = SwingSlider {
    minimum: 10;
    maximum: 250;
    value: bind tempSliderVal with inverse;
    onMouseDragged: function (e:MouseEvent) {
        BPMDisplay.text = tempSliderVal.toString();
    onMouseClicked: function (e:MouseEvent) {
        BPMDisplay.text = tempSliderVal.toString();
}; //BPMSlider
var BPMDisplay = TextBox {
     text: tempSliderVal.toString();
    columns: 3;
}; //BPMDisplay;
Stage {
    title: "Slider";
    width: 1000;
    height: 500;
    visible: true;
    // Set the scene
    scene: Scene {
        content: HBox{
            spacing: 10;
            content:[ BPMSlider, BPMDisplay ];
    } // Scene
}
