In the image, the color of the frame of the window/JFrame is black. My question is that can we set the color of this frame, or is it just provided by the operating system and whatever color is default color of windows in an operating system will appear in our application?
I am talking about the frame, the boundary in the JFrame container which contains the close, maximize, and minimize buttons.
The Toys of the Future Company has decided to issue a new line of toy robots. While they are not sure exactly what their robots will look like, they do know the functionality that they will all have. All robots will be able to move forward, turn right, turn left, spin and detect an object in front of it via a sensor. The robot will use a touch sensor to determine whether it has hit an object in front of it, such as a wall. The robot will have two, three, or four wheels, but it will only be driven by two of them: a right wheel and a left wheel. Each wheel will be attached to a motor that controls it.
* ^ this is only something to think about Produce a UML class diagram.
Using UML, describe the objects and classes that will be associated with this new toy. Either hand draw or use an appropriate UML creation tool to generate a UML design document for your Robot class. Create a set of classes that can be used to control the robot.
Develop your new class.
Create a new NetBeans project entitled, "Assignment_8_1" and develop your new class. Now, using the objects and classes that you have written, write a program for your robot that allows it to move in a large square. Allow your robot to run in a big two dimensional array and every time the robot encounters a square in your array, turn that square black.
So here is the code for the moving ball:
package ballapplet; import java.awt.*; import java.util.Formatter; import javax.swing.*; public class BallApplet extends JPanel { private static final int BOX_WIDTH = 640;
[Code] ....
I want to know how to change the color of an object, and how to move it in specific directions.
I have a major problem. the text size is like 6 or 8 pt font and I can't read it. I'm trying to run a downloaded exe program which uses the jre7 which I had to download beforehand. the font size stays at 6 or 8 even if I try to change it in windows settings. it's a high res monitor on a lenovo yoga laptop. is there a way for me to edit the java code and manually change the font size?
My program has a MainFrame(extends JFrame)class and BasePanel(extends JPanel) class,and many other panels.I had used Images with JLabel in BasePanel.My current panel in MainFrame is BasePanel.I had used MouseListener so that when I click on any of the label it should show Other panel in same MainFrame and hide the BasePanel.But I am getting some problem with that.When I click on the Label,It hides the BasePanel but do not show the new Panel(Dictionary Panel in my code). In short when label is clicked I want to make DictionaryPanel visible and BasePanel invisible,both in MainFrame. I am using the following code on Label:
//constructor of BasePanel class public BasePanel() { dict=new Dictionary(); mf=new MainFrame(); dictLabel.addMouseListener(new MouseListener() { public void mouseReleased(MouseEvent arg0) {
But the error is giving me incompatible types. I would like to set all the pixels at a certain point up to the dimensions of my rectangle and so on. How would I do that?
I'm trying to build a program which sets a fill color for a rectangle. Each time the mouse is clicked the fill color changes according to the position of the mouse's X and Y. I succeeded to create a JFrame with a changing background according to the Mouse's position, but I can't seem to change the color of the rectangle (defined in MyPanel class).
is there a good way to change the color of a JList item that isn't selected? I'm throwing my hand at building a client/server chat app and on the client side, I need to highlight the name of the person (which is in a JList) who has sent a message to the client GUI.
I am trying to create a virus simulation program. The program is supposed to just be a map of the world where the user can click any country in the world to specify where they want their virus to start, specify how transmittable the virus is, and be able to see how the virus spreads through the world by seeing a change in color throughout the world,
I want the world map to initially start out with a very light yellow, and as areas of the world slowly start to get more and more infected by the virus, I want those areas on the map to start changing to a very dark red (going from a light yellow, through shades of orange and red, to dark red).
So, the main idea of this is to have a program that displays an image where certain parts of the image will slowly change color during the runtime of the program. I obviously know how to change colors of certain parts of a window or even an image, and how to even start this.
I'm struggling to change the colour of the X and Y axis. I can change the colour of the ticks and the tick labels in CSS... But not the axis themselves.
how to change the color of an output element in Eclipse? Can't seem to find it anywhere on the internet.For example, a response to my question 'What color do you want?' could be 'red'. I added an if-statement, which states if input = red, start using a red colored 'X' as string for further output.How do I obtain the color red for my X?? Or isn't it possible changing the color of output elements?

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.
I've just started working on a program and i'm already having difficulties with the program. I can't get the background color to change from the basic gray color. Maybe you can tell me what i'm doing wrong.
import javax.swing.JFrame; import javax.swing.WindowConstants; import java.awt.*; import java.lang.Object; import java.awt.Color; public class FrameDemo{ public static void main(String args[]){ Toolkit toolkit = Toolkit.getDefaultToolkit ();
[Code]...
also if theres any way to shorten up what I have there, that would be great.
If I want to read from file the word "red" And then the following is not the right way like in the code ,, How to set the Color name
File inputFile = new File ("C:\input.txt"); Scanner scan = new Scanner (inputFile); String RedColor=scan.nextLine(); Color backColor = new Color(redColor);
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
i am using a frame over which i am loading a dialog. The singleton dialog holds a progress bar. I have created my own swing worker. i am controlling the construct method of swing worker(which functions like doInBackground method).I am trying to call hidedialog from an external file. The dialog gets stuck sometimes. How do i solve it . It works fine on win7 but fails on win8.
I've just got a new computer and i tried to set the class path the way i did with windows xp but it's not working. This is what i have done. I added a Path variable to user variables and added C: Program Files (x86)Javajdk1.6.0_20/bin as the variable value. But when i got to command prompt and type javac HelloWorld.java it just tells me javac is not recognised as an internal or external command.
Also another problem is after trying this and it not working i tried to add a path to the system variables. I added a new path variable but i think once i did that it deleted the one that was already there. Is that going to mess up my computer? What the default path variable for windows 7 is?i've got the right destination as i typed cd to change directory and when i typed C: Program Files (x86)Javajdk1.6.0_20/bin it changed to that. And i noticed if i typed in the destination wrong its just made an error.
Cannot reinstall java on this windows xp. Get an error -1 and install didn't complete. There are no java versions installed and apparently no java control panel either.
I have a game which is very simple: it is two images, and one needs to reach the other. Once it does, it resets. I have a class which holds the two images, and another which holds the game. My images class extends my game class. The problem I am having is that when I run the program, not one, but two frames appear. One is the perfect game, working perfectly, and the other is the game without images. I want the one that is the game without images to simply stop appearing. I believe it is appearing because my class that displays the image is extending the game class, but I can't not extend it because if I do I get a whole lot of bugs and errors.
I want to create a Web page which can monitor and display the status of Schedule Tasks setup on different remote machine. This Dashboard should also has the capability to re-run the schedule task.
I know that I can achieve this via Runtime class by running schtasks /Query and get all the details. But I just wanted to know if we have any other better way to do this.
I manage a small company through our bank's online system, that uses java, but I can't access it through any browser , they all give the same issue; after I choose the certificate file on my PC, nothing happens.
If i dual boot Ubuntu on my PC it works, so it's clearly something with the Windows installation.
Things tried :
- Reinstall Java, multiple times - Clean anything Java and Oracle related in my PC (except registry, I don't know how to fuzz with that) - Different browsers
