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.
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 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..
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've been looking through the Java API for a component similar to the direction selector compass in google earth (the one that acts like a circular scroll bar) to no avail. Any existing component before breaking down to creating the component myself.
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 am developing an application where blind person can interact with computer i have completed the part where computer responds as per command given by user.The part where i am stuck is i want to give voice feedback as user moves the curser for example if mouse is on d drive then user should get feedback that its d drive....i want to do it for whole windows ...
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:
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?
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.
