JavaFX 2.0 :: Remove Style From Component?
Oct 28, 2014
I am using the Javafx 8 Date Picker. Its works fine. I have defined a stylesheet for my application and in that style sheet i have a style for Button. I apply this style to the every scene. Now my question is: When I use the datepicker and I click on the calendar icon, the datepicker popup appears and the left and right arrows adjacent to month and year fields in the seems to pick the style of the button class from style sheet defined in my application., Is there a way to avert this and tell datepicker to use default styles and not the styles defined my application.
I tried removing the style at runtime from the scene, but of no use.

I have a column of my TableView that just shows row numbers, and I would like to style the cells in that column so that they appears just like a column header (so the same styling as the headers use). I presume there is some simple way to do this by tapping into the right style class, but I am not sure which one.

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).

I have a big issue to render this html page with the webview component :
<html><head lang="en"> <meta charset="UTF-8"> <title>Pb Rotate</title> <style type="text/css"> #myDivRotate {
color: purple; background-color: #d8da3d; height: 200px; width: 300px; margin-top: 20px; margin-left:20px; -webkit-transform:perspective(400px) rotateX(30deg); -webkit-backface-visibility: visible; }
</style></head><body> <div id="myDivRotate"> Coucou
</div></body></html>
The problem is from "perspective" in -webkit-transform. Without it's ok. But with this one, the result is different from a standard browser like chrome or safari.

I have the following application scenario:
a) I have an observable list L
b) I have a thread periodically adding to L
c) I have a UI component monitoring changes in L and updating some view.
At present my thread adds to L by doing a platform.runLater. I find that a little clunky (not sure why, just seems it).
Are there any other recommended ways/petterns to keep my UI view in synch with the list, other than the above approach?

I have a JPanel that's using a simple GridBagLayout.
JPanel panel = new JPanel();
GridBagLayout qPanelLayout = new GridBagLayout();
qPanelLayout.columnWidths = new int[] { 0 };
qPanelLayout.rowHeights = new int[] { 0 };
qPanelLayout.columnWeights = new double[] { Double.MIN_VALUE };
qPanelLayout.rowWeights = new double[] { 0.0 };
panel.setLayout(qPanelLayout);
componentCount = 0;
Based on user input I am adding sub-panels to the panel. These sub-panels may vary in height. They take up the full width of the Panel.
public void add(Component comp) {
GridBagConstraints gbc = new GridBagConstraints();
gbc.fill = GridBagConstraints.HORIZONTAL;
gbc.insets = new Insets(2,2,2,2);
gbc.gridx = 0;
gbc.gridy = componentCount++;
panel.add(comp, gbc_questionPane1);
}
The odd behaviour I'm seeing is that if the height of the new sub-panel I'm adding is less than the height of the largest sub-panel currently displayed then the main panel does not repaint. If its height is equal or greater then the Panel does repaint, and any sub-panels that were added but not visible before are now painted. What have I missed?

I just started Java programming bout 3wks ago and using jGrasp since then. But ive started using eclipse and just wondering if it can be set up to use allman style? I dont like having to use tab and backspace to get my brackets in line and neat. I decided to ask before i went snooping around the settings and mess something up since im not to familiar with it right now.

I have a routine that returns a boolean. If any of a series of tests fails, the routine returns false, otherwise it returns true. For example, the routine might test for whether or not an integer is both odd and greater than 99, thus:
public boolean oddAndOld(int x)
{
if (x % 2 == 0)
return false;
if (x < 100)
return false;
return true;
}
I like the above because it suggests that "true" is the condition that applies if the incoming parameter meets all the required criteria. But I've sometimes seen this style used:
public boolean oddAndOld(int x)
{
if (x % 2 == 0)
return false;
if (x < 100)
return false;
else
return true;
}
I like this less because, among other things, if that last criterion is removed, the "else/return true" must be moved up into the immediately preceding test (or else leave some funny whitespace, depending on how you go about removing the departing "if" statement), but it does avoid suggesting that "return true" is hard-coded (that is, it reinforces that "true" is a conditional return value, not inevitable).

The Font style constants are of int: int[] fontStyleList = new int[] {Font.PLAIN, Font.BOLD, Font.ITALIC};But what do I do when I want to add the names such as PLAIN etc. as the name of a menu item?
The following is not going to work, right!String[] parts = (fontStyleList[i].toString()).split("."); or String[] parts = ("" + fontStyleList[i]).split(".");rbStyle = new JRadioButtonMenuItem(parts[1]);
Is there another way to do this or should I just do another array with the names as a String?

I've been into java for about 4 months now, No complaints so far, it's pretty awesome! So I understand Polymophism pretty good, I did some Animal classes and it worked out neatly.
However. I just can't seem to find my way in OOP when trying to implement in on a Calculator Class I wrote. As you mind know, a calculator can be separated into many classes. But I actually just want it to be separated into some OO like: | Calculator | CalcGUI | CalculatorFunctions | CalcRun.
I tried separating the single Calculator class, however, my calculator Buttons didn't work after that, anymore..
here is my code:
import java.awt.GridLayout;
import java.awt.Panel;
import java.awt.TextField;
import java.awt.Button;
import java.awt.Menu;
[Code] ....

I'm attempting to make a simple Pythagorean Theorem program (A squared + B squared = C squared) but am running into problems when I write it as object oriented. The darn thing works when written as a simple process, but that isn't Java now is it? Here's the simple:
public class PythagoreanTheorem extends ConsoleProgram {
public void run() {
println ("Finding C from A and B.");
double a1 = readDouble("Input A: ");
double b1 = readDouble("Input B: ");
double aSq = (a1*a1);
double bSq = (b1*b1);
double cSq = (aSq + bSq);
double c = Math.sqrt(cSq);
println ("C = " + c);

I cannot add the component from this class:
Java Code:
package TestVersion;
import java.awt.Color;
import java.awt.Graphics;
public class matWood {
private int woodX = 250;
private int woodY = 100;
[Code] ....
The error is at Java Code:
frame.add(matWood); mh_sh_highlight_all('java');
And this is what it says:
The method add(Component) in the type Container is not applicable for the arguments (matWood)

In a java application project called mycomposites, i created xhtml with a composite component interface and implementation in mycomposites/ src/ main/resources/testcomponents/myComponent.xhtml...Then I created a new project testmycomposites added mycomposites as dependency. Here is the source of an xhtml that should use myComponent:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
[code]...
However running project, I get error:<tp:myComponent> Tag Library supports namespace: http://java.sun.com/jsf/composite/testcomponents, but no tag was defined for name: myComponent
If i put the same custom component in resources/testcomponents folder of the same project everything works fine.I can't find any example in wich custom composite components are located in a dependency.

I have created a text file that contains a small list of toy names and prices, like:
Barbie, 12.95
Lego, 15.99
Hot Wheels, 5.00
Power Rangers, 6.49
And what I would like is my application to read the contents of the file and store the toy names in a list component. And then I want to be able to select a toy name from the list and add it to a shopping cart that is a list component as well. I want to the application to have menu items and buttons to allow me to remove items from the shopping cart, clear the shopping cart of all selections, and check out.
When I check out, the application should calculate and display the subtotal of all the toy names in the shopping cart, the sales tax (which can just be 8 percent of the subtotal), and the total.
How to create this simple application example I've just made up, and I'm going to add and use this example to create a bigger application myself.

I have an issue about loading images from css using a composite component. The folder structure is:
resources
resources -> css -> componentname
resources -> images - > componentname
resources -> WEB-INF
If i write in the css something like
border-image: url(resources/images/componentname/image.png) !important;
or
border-image: url(images/componentname/image.png) !important;
i have a 404 error and i can't see the image.
I able to load the image only if i write path with context-root:
border-image: url(/<CONTEXTROOT>/resources/images/componentname/image.png) !important;
but i can't write explicit context root in css files!!
So, i tried to use resource EL variable:
border-image: url(#{resource[image/componentname/image.png]}) !important;
but this last way render
border-image: url("/<CONTEXTROOT>/javax.faces.resource/images/componentname/image.png.faces.faces") !important;
and i not able to replicate the right way written above.
The project is developed with RSA9 and WebSphere Portal 8, but if i try to execute it in NetBeans (no portal) it run correctly!

I have to create a new custom tag "imageLabeable" as a div contains a GraphicImage and an OutputLabel (primefaces).
Since I want to make it reusable as much as possible, I tried to write, in cc:interface section, all GraphicImage attributes (id, value, binding etc) and some new (GraphicImage is the main component among the two). But after that I have must associate GraphicImage attributes with the attributes created in cc:interface:
<cc:interface componentType="imageLabeable">
<cc:attribute name="value" />
<cc:attribute name="alt" />
<cc:attribute name="width" />
<cc:attribute name="height" />
[Code] .....
As you can see, if I have a lot of attributes I have to write a lot of association. Furthermore, if I see html rendered code with Firebug or similar, I see all of these associations.
Can I inherit these attributes automatically? Or associate it in easier way?

<f:selectItem itemLabel="Option1" itemValue="2"/>
<f:selectItem itemLabel="Option1" itemValue="3"/>
</tr:selectOneChoice>
Supposed that selectItem loads a list from the database.
But I want to display "Option1 - testing" without modifying database value.
testing is a string datatype in the backing bean

I heard one of the senior architects in my company before tell me to treat component distribution as a last resort. So if EJB were created for such, why were they created if component distribution is not encouraged anyway? just got confused here. I remembered this because I am currently in a dilemma of whether to redesign an app having performance problems. Options are either create EJBs for it and put them in another server or purchase another server to have a load balanced setup.
