JavaFX 2.0 :: Setting Color Of A TableRow

Jun 4, 2014

I would like to change the color of the rows of my TableView. But the instruction setTextFill doesn't work. Is it normal ?
 
tableView.setRowFactory(new Callback<TableView<Person>, TableRow<Person>>() {
    @Override
    public TableRow<Person> call(TableView<Person> param) {
        final TableRow<Person> row = new TableRow<Person>() {
            @Override
            protected void updateItem(Person person, boolean empty) {
                super.updateItem(person, empty);
                setTextFill(Color.RED);
            }
        };
        return row;
    }
});

JavaFX 2.0 :: Setting Background Color For Layout - Fill / Color On OS X

Jun 10, 2014

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.

JavaFX 2.0 :: Color-lookup Not Resolved In SceneBuilder

Jun 17, 2014

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

import java.lang.Object;
import java.awt.Color;
public class FrameDemo{
public static void main(String args[]){
Toolkit toolkit = Toolkit.getDefaultToolkit ();

Rubik Cube - Aligning Middle Side Color With Bottom Middle Side Color

Jan 16, 2015

I am trying to align the core/middle side color of a cube, index 4, with the bottom middle color of the same side, index 7. (Each side has values 0-8 where 0 - is the top left corner, 1 is the top mid corner, 2 is the top right corner, 3 is the middle left corner, etc).

In addition to lining up those two colors, I am also making sure that the neighbor color of index 7(the color that it is attached), in this case the bottom color, matches with the top core/middle color. I will attach some pictures and a print out to show what I am talking about...

However, in my code when I am trying to align all of these up together, it does not go into the while loop. Each of the loops essentially is trying to get a match of same color with index 4 and 7, as well as making sure that index 7's neighbor color (the bottom color, in this case) matches with the top color.

Here is what I have tried:

private void alignSideColor(){//make the bottom colors neighbor match with a middle side value and rotate it to the top, for the top cross

if(cube.bottom.square[1].charAt(0) == topColor){
while(cube.front.square[7].charAt(0) != frontColor && cube.bottom.square[1].charAt(0) != topColor){
rotateBottomClockwise(1);
System.out.println("Trying to align side color...");

[Code] .....

The print out of the ELSE IF is:
alignment is: W-G and tops: R-R
NOW ITS ALIGNED
even though the sides, index 4 and 7, are NOT aligned with each other

I have also tried the same thing but with out the 2nd condition in each while loop, and although is DOES enter the while loop, it does not perform correctly -- index 4 and 7 WILL have matches colors, but it does not check to see if index 7's neighbor matches with the top color.

Here is how it prints out
** ** ** G7 B6 Y1 ** ** **//this portion is the back of the cube
** ** ** R6 W5 O4 ** ** **
** ** ** R3 W2 O1 ** ** **
B3 G4 Y9 W9 O8 Y7 W3 B4 G9//this portion is the left, top, and right of the cube
B2 G5 R8 W4 R5 Y6 O2 B5 G8
O7 W8 R9 B7 B8 B9 R1 R4 R7
** ** ** O3 O6 O9 ** ** **//this portion is the front of the cube
** ** ** Y2 Y5 Y8 ** ** **
** ** ** B1 G6 W7 ** ** **
** ** ** Y3 Y4 G1 ** ** **//this portion is the bottom the cube
** ** ** R2 O5 G2 ** ** **
** ** ** W1 W6 G3 ** ** **

Here is the cube showing the top, left and front side

Here is the left and bottom side. As you can see index 4, G5 -- yes that is a 5 lol -- does not have the same color as index 7, W8.

I need to rotate the bottom until W8 is aligned with a middle white value. An examples of a neighbor is: W8-R2

Setting A String Using If

Here are two codes that I am using but I have one that just doesn't work for some reason and the other does. Encode doesn't work. I don't need the Character.isAlphabetic for encode but not sure what I can use with 'if' to set the String encodedString.

Java Code:

private String prepareString(String plainText)
{
String preparedString = "";
for(int i = 0 ; i < plainText.length();i++)
if(Character.isAlphabetic(plainText.charAt(i)))
{
preparedString = preparedString+Character.toUpperCase(plainText.charAt(i));

Error Setting Value For JSpinner

Apr 19, 2014

I'm using a jSpinner Number model:

Here's my code:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
int qty2, total, payment, change;
String title;

[code]....

I tried using this since the jSpinner's minimum value is 1.. (I want it to reset the jSpinner after updating the database):

jSpinner1.setValue(new Integer(1));

But gives me an error:

Setting Background Of JScrollPane?

Aug 19, 2014

My program's tree:

JFrame{
JPanel(That MenuBar at the top)
JPanel(That panel at center with table){
JScrollPane{
JTable
}
}
}

I want to add my custom image to that grey space right there. I guess it is a JScrollPane, because I added that orange background on JPanel that contains it. But when I add this code to my custom class of JScrollPane:

@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
if(background == null){
background = new ImageIcon(ClassLoader.getSystemResource("tableBg.png")).getImage();
}
g.drawImage(background, 0, 0, null);
}

The result is the same, no changes.

Then I read some documentation. I found this method:

scrollPane.getViewport().setBackground(Color c);

It works, but it accepts only color and I want to add image. Is there any way to do that? Do I need to subclass JViewport and use paintComponent ? If yes, then how to make getViewport() method return my custom subclassed version?

Setting Values In PDF Field?

Dec 12, 2014

I have a PDF file and I have a text file that contains this data. It has the name of a PDF field along with a database table column name.

Text file: pdfFieldEmployee=Employee; pdfFieldStartDate=StartDate; pdfFieldSalary=Salary; pdfFieldExempt=Exempt

I also have this hash map that contains the database table column names along with their corresponding values:

Employee, Don Parker
StartDate, 5/6/2000
Salary, $55000
Exempt, N

How would I read through the text file and the hash map and at the same time do this:

if the pdf field is equal to pdfFieldEmployee, then set pdfFieldEmployee equal to Don Parker.
if the pdf field is equal to pdfFieldStartDate, then set pdfFieldStartDate equal to 5/6/2000.

and so on and so on. I would prefer to do this with a loop because I think it would take less code than writing a bunch of if statements.

This is my frame class, now I want to be able to change the name of the frame, and get the name with frame.getName() in another class. But I'm not sure how to do this, i tried making a new frame in that class but i feel it's just another frame and not the one i made, also tried something like

public JFrame getFrame(){
this.getFrame();
}

and few variations but it was wrong.

What Does Setting Object Equal To Another Do

Mar 5, 2014

I've seen this done in code:

For example:

Java Code: BufferedImageOp op = new ConvolveOp() mh_sh_highlight_all('java');

What does this mean? Is it creating an object of convolveOP for the BufferedImage class?

What does it mean when you set an object from one class equal to another?

Setting Brightness With RescaleOp

Jul 3, 2014

When I try to brighten my BufferedImages with RescaleOp, they are cut in half, and not brightened at all. However, strangely enough, when I tried to run the same program on another computer they were not cut in half, but only one half of the image was brightened. Here are two images displaying the issue:

Before brightening:

After brightening:

Why does this happen? Are the images not loaded properly, or am I simply not using the class correctly? Here is my code:

Java Code: ...

RescaleOp op = new RescaleOp(1.2f, 0.0f, null);
op.filter(enemies.get(y).getImage(), enemies.get(y).getImage());
... mh_sh_highlight_all('java');

Swing/AWT/SWT :: Setting Size Of JFrame

May 26, 2014

I am rather new to Swing, and I am building a game right now in which I need to display a pop-up window as a reminder for what commands exist within the game. I created a class extending JFrame for this and added all the information I need. However, for some reason, no matter how many different ways I try to set the size of this window (setSize(w, h), pack(), using a different layout, adding the compnents to a JPanel first and setting the preffered size of that, then adding the JPanel to the JFrame), it doesn't work. Instead of a window of my requested size, I get a tiny, maybe 100 x 100 pixel window that needs to be resized in order for its contents to be visible.

import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.GridLayout;
import java.awt.Toolkit;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

Swing/AWT/SWT :: Setting Icon On JButton

Feb 23, 2014

Recently I have been working on an executable launcher. I tried to get the executable icons and set them on the JButtons. Still there are some problems. Here is a part of the code:

try {
button[i].setIcon(FileSystemView.getFileSystemView().getSystemIcon(new File(getConfig("path." + (i+1)))));
}
catch (NullPointerException ex) {
}

Here the getConfig() method is already defined to get a string in a "properties" file. However, the icons are very small and they don't fill the entire button.

How can the icon fill the entire button (for example, having a custom size of 48x48, or automatically filled the button)? The frame will not be resized.

Here is the whole code...

import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.*;
import java.io.File.*;

Recursive Implantation For Setting Objects

Apr 8, 2015

I have a requirement where I have a class as Page which itself contains ArrayList<Page>.Here ArrayList<Page> is nothing but the pages which are accessible from the base Page.I know the depth level ( reading from file) which means how many level I need to go to identify more pages.BUT the problem is how to set the base Page class. I need to set the base Page class but for that I need the objects for the subsequent pages and hence an iterative type of implementation.
