I'm programming in school using Netbeans and we've just started with graphical programming (i.e JPanel, JClass, JFrame). This is my first assignment and the purpose of this program is that when you press the mouse you will fill 4 circles with diffrent colors. I've managed to draw 4 circles with diffrent colors but I want my cursor to change color simultaneously. Here's my code so far ....
//Java klass "Klick"
public class Klick {
//Medlemsvariabler.
private int x = 0;
private int y = 0;
private int r = 1;
public int antal = Rityta.antalKlick;
This is my code. It is running great until I enter in the final color and hit enter. I get an Array Index out of bounds error, which I show at the bottom. I have fiddled with it, by moving the all answers correct into an if..else statement, hoping it would fix it. Needless to say, it didn't work.
Also, I am trying to figure out how to make the cursor appear in each guess box. It does in the first one, but after I hit enter, I have to click in the box each time to get one.
import javax.swing.*; import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; public class RobertMaloneChapter17 extends JFrame { //final variables to set the width and height of my frame
[Code] ....
My Errors:
Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 5 at RobertMaloneChapter17$Listener.actionPerformed(RobertMaloneChapter17.java:67) at javax.swing.JTextField.fireActionPerformed(JTextField.java:508) at javax.swing.JTextField.postActionEvent(JTextField.java:721)
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.
I decided to change the mouse cursor based on the theme of the game. This is the code that I wrote for the declaration of the cursor:
ImageIcon imageIcon = new ImageIcon ("cursor / cursor.gif"); Image img = imageIcon.getImage (); Toolkit t = Toolkit.getDefaultToolkit (); Cursor cursor = t.createCustomCursor (img, new Point (0,0), "cur"); this.setCursor (cursor);
Having to click on different JButton in the menu of the game, a few screens later, I have to manage something in particular, such as determining the point of clicks that allows the action to take place?
In particular I would like to change the point of hotspots. The size of 136x163 is cursor.gif
Image - TinyPic - Servizio di hosting d'immagini, condivisione immagini & hosting di video gratuito
As you can see in the image I want to create the point of hotspots in the red dot of the image. How should I do to pass the correct coordinates in Point?
i java a project with java draw golf course and currently working on 2 combo boxes to change shape of the flag on the post and fill color as well on combo box item change. I have below code. as am new to java what to do next.
import java.awt.*; import java.awt.event.ItemEvent; import javax.swing.*; public class GulfCourse extends JPanel{ public void paintComponent( Graphics g){ super.paintComponents(g); //draw green oval
I am creating a JSP page with a html table to display employee directory. This is scriptlet :
<% List<Employee> list = new ArrayList<Employee>(); PhoneListController controller = new PhoneListController(); list = controller.getAllContacts(); for (Employee eachEmp : list) { %>
and then i display the table rows and columns for each employee object(PS: I know scriptlets are bad and obsolete but this is my first individual project.)
I would like to change the background color of certain rows based on value of one particular value(based on eachEmp.getManagerCode).
How can i achieve that by using javascript? I tried to call a js function by calling onload event on . But as I need to check for each row that is not the possible solution. I have not tried jquery yet as I am very new to jquery and I didnt quite understand how to do it in jquery.
I am having problem with the JRadio Buttons to change the font color in my code. What needs to be done? Also if I were to connect this GUI to another GUI and save font colors, how would I go about that?
I'm working on a spreadsheet-like table and I was able to set it so that it would highlight the first cell in the relevant row(titled 1,2,3.. etc) when a cell is clicked. (Just like in MS Excel - preview attached) Now I want to do the same to the column header(i.e. A,B,C,D....etc) . How can I do it?
private void formWindowOpened(java.awt.event.WindowEvent evt) { setLocationRelativeTo(null); int rowNum = sheet.getRowCount(); for(int i=0; i<rowNum; i++){ sheet.setValueAt(i+1, i, 0);
I'm dealing with, change the content pane color of jFilechooser. Color has been changed but the problem is when I open the subdirectory leads errors; Note : It also trigger error when I set default directory; like chooser.setCurrentDirectory(file);
The following error is the result:
Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException at javax.swing.plaf.metal.MetalFileChooserUI$IndentIcon.getIconWidth(MetalFileChooserUI.java:912) at javax.swing.SwingUtilities.layoutCompoundLabelImpl(SwingUtilities.java:961) at javax.swing.SwingUtilities.layoutCompoundLabel(SwingUtilities.java:888) at javax.swing.plaf.basic.BasicLabelUI.layoutCL(BasicLabelUI.java:94) at javax.swing.plaf.basic.BasicLabelUI.getPreferredSize(BasicLabelUI.java:239)
is possibile to change the color of the sorting arrow that appears in the columns of the Table View by css? My attempts have failed and I have not found any documentation, nor is there any reference in the Modena css.
What I'm trying to do is basically draw a Rectangle outline through left-click and then dragging the mouse to the size one wants.
After one has created this rectangle, the user can change the color of the rectangle through clicking the 3 sliders found on the top in the program. Upon the change in color, the rectangle should change from "g.drawRect" to "g.fillRect" and use the desired color.
I have the basic outline of the program done, but working with the last part (the color and changing of the Rectangle type after changing the color)
Is there like a "then" command in Java? Like: after you've done x, do y. That would make this heaps easier.

I have to implement the methods for what is happening if on some panel the action selected are Remove/Move/Change/Resize (Draw is already implemented).
The Applet in question draws ovals or rectangles on the screen and you can change the fill-color and outline-color of the shape. All this works already. I have dabbled with the move-method, but am not going anywhere.
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.
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 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 ...
My problem is simple. Just set busy cursor on a scene. The scenarios is like this: I have simple application with a button on it. When I click the button, I will:
1. Set mouse cursor to BUSY 2. Do some work 3. Set mouse cursor back to DEFAULT.
I search the web and found some sample codes to set cursor. But they don't satisfy my need. So I wrote a simple application:
public class MainFormApp extends Application { @Override public void start(Stage stage) throws Exception { stage.initStyle(StageStyle.DECORATED); Pane root = new Pane(); root.setPrefSize(500, 300); Button btn = new Button("Click me");
[Code] ....
When I run application and click the button, cursor does not change to BUSY. I also tried to use Platform.runLater() but no luck.
I've been creating a digital clock using Java, and have made the mouse cursor invisible after a set period of time (40-seconds) and had the thought to make it visible again if mouse was moved.
Here's the code that makes it invisible:
ActionListener mouseTimeout = new ActionListener() { public void actionPerformed(ActionEvent e) { setCursor(blankCursor); } }; /* Make mouse cursor disappear after 40 seconds */ Timer mTimeout = new Timer(40000, mouseTimeout); mTimeout.start();
And here is what I have so far for making it visible again:
MouseMotionListener mouse = new MouseMotionListener() { @Override public void mouseDragged(MouseEvent e) { } @Override public void mouseMoved(MouseEvent e) { } };
I have tried using "setCursor(DEFAULT_CURSOR)" but NetBeans says that it "cannot find symbol" .....
I have now slowly moving on the learning Database Connectivity.Found a simple example on one site and tried to execute it, Creating a database, connecting to it and displaying the output.
I am getting trouble with recordset in displaying all the records in the badabase. It displays the very first record correctly but if I try to enclose it in while(rs.next()) loop, it generates an error message saying "Invalid operation at current cursor position".
