Animating JButton When Mouse Moved
Jan 24, 2014
I'm creating a program to animate Button.
When Mouse is moved on JButton the Button slowly disappears and when the mouse is moved away from the Button it appears again.
Every thing is working fine except an error which i can't understand.
Java Code:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class AnimatedButton{
private JFrame frame= new JFrame("Animated Button");
private Animate b1= new Animate("OKAY");
float initialAlpha;
Timer t;
float incrementAlpha = -.03f;
[Code] ....
The error is:
XML Code: [HTML]Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: alpha value out of range
at java.awt.AlphaComposite.<init>(Unknown Source)
at java.awt.AlphaComposite.getInstance(Unknown Source)
at Animate.paintComponent(Animate.java:26)
at javax.swing.JComponent.paint(Unknown Source)
[Code] ...

I have made a window using JFrame and on my JPanel I have added 3 components: 2 JTextFields ("field1" and "field2") and inbetween them a JButton ("switch"). My goal is to switch the value of field1 to field2 and vice versa when the JButton is clicked. I thought this ActionListener which I have added to my JButton would achieve my goal:
public void actionPerformed(ActionEvent e) {
field2.setText(field1.getText());
field1.setText(field2.getText());
}
However, it changes the value of field2 into the value of field1 but not the other way around.

Alright, so I'm having problems with lines 11 - 55. I'm trying to calculate the possible tiles the clicked unit can be moved on and display it to the player.
The field is a 9 (columns) by 5 (rows) grid. A unit with can move tiles horizontally or vertically based on its movement.
Example: (unit = o; possible tiles = x) (assuming movement of 2).
[ ][ ][ ][ ][x][ ][ ][ ][ ]
[ ][ ][ ][x][x][x][ ][ ][ ]
[ ][ ][x][x][o][x][x][ ][ ]
[ ][ ][ ][x][x][x][][ ][ ]
[ ][ ][ ][ ][x][ ][ ][ ][ ]
I tried to calculate movement by finding out what column the unit is in, subtracting the column it wants to go to, multiplying the difference by *-1 if the difference is less than 0. Then, doing the same with rows and adding the difference of columns to the difference of rows and comparing it to the unit's movement. Unfortunately, with my code, it seems to move in any directions.
@Override
public void mouseClicked(MouseEvent e) {
if (Main.cards.size() > 0) {
mainloop: for (int i = 0; i < Main.cards.size(); i++) {
Card c = (Card) Main.cards.get(i);
int startingColumn = 0;

I am trying to have a Jbutton (blocker02) act like a wall that will not allow a moving Jbutton to pass through. I tried using " if (blocker02. getBounds (). intersects(r_wall)) but it hasn't been successful.

So I'm making a trading card game and each card can be moved around like chess pieces. So far, I've made the cards simple rectangles and detect if clicks are made within that rectangle and then move them appropriately, but I'm not sure if that's the best solution.

I am using Eclipse programming for android. I have a game working fine but looking to add a little flare to it. Currently more scoring system just displays the current sore so if your score is 3,000 and you score 300 more it just changes to 3,300.
My question is how can I get the score to count from 3,000 to 3,300 really fast giving it the arcade feel of your score counting up? I tried timers with delays but it gets slowed down and buggy.

I have been working on this mouse movement code that detects which direction the mouse moves in hope to use it in a game. The only problem is that I can not figure out how to make it move to the other side of the screen so I could continue turning to the right or left without having to stop. How would I actually get the x and y coordinants of the mouse to change?
PHP Code: if(x == xscreen){
//set x to 0
}else if(x == 0){
//set x to xscreen
}else if(y == yscreen){
//set y to 0
}else if(y == 0){
//set y to yscreen
} mh_sh_highlight_all('php');

The program i am creating consists of two JPanels (currently) and one canvas. The canvas is in the center of the JFrame, while flanked by JPanels where both have 13 buttons each.
To paint a simple picture, my program will draw letters on the middle canvas when a button is clicked.
I created my own buttons that implement the ActionListener interface , so when a button is clicked it will display its character in the console. But my question is, How do you implement the listener to draw something on the Canvas when the button's are clicked?

I'm running the code below which compiles ok using latest version of Java and on Sublime. The problem when it complies the output screen is blank and I can only see the text by adjusting the size of the box with my mouse - and then it colours in black. Code and screenshot below. Is there something wrong with the paint/graf part of the code?

import javax.swing.*;
public class BackArray extends JFrame {
int store[] = {2,6,4,8,34,67,19,99,10,12,89,68,45,37};
int xcoord = 100;
boolean firsttime=true;

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?

So I'm making buttons for a game I'm making. The graphics work, at least to the extent that I don't have to fix them yet. However, click detection is a bit iffy. For example pressing where the black line is in the first picture below, triggers a response. Now obviously that point is not on the button. I have tested the buttons bounding box by drawing a rectangle around it, using it's getBounds() method (which is also used for click detection) and it draws a perfect rectangle around it. So then I tested the mouse click points and it turns out that even though the button is placed at y = 100, at the black line, the mouse point is also equal to 100... Now, why that is happening, especially because, if I place the button in the top left corner, the mouse detection correctly detects the top pixels and there is no offset...

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" .....

What it's supposed to do: This code is supposed to see if the clicked card is selected. If it's not, select it and show the player where it can move / attack. If it is selected, then find out what card the player clicked on. If he clicked on the card that was already selected, deselect it. If he clicks on a friendly card (same playerID), then select that card. If he clicks on an enemy card (different playerID), attack that card. If he clicks on a tile, move it to that tile.
The problem: However, line 24-58 give me a bit of a problem. Right now, it works fine BECAUSE lines 46-58 are commented (which also means the unit can't move). If I uncomment those lines, the unit becomes able to move, however, lines 34-46 cease working...
Java Code:
@Override
public void mouseClicked(MouseEvent e) {
mainloop: for (int i = 0; i < Main.cards.size(); i++) {
Card c = (Card) Main.cards.get(i);
if (Card.cardSelected == null) {// Contains / Is not selected
if (c.contains(e.getX(), e.getY())) {
Tile.reset();
Card.reset();
Card.cardSelected = c;

Is there a possibility to use events for additional mouse buttons, like the next or previous mouse buttons, in javafx? If I use the setOnMousePressed event on a node, it only throws an event for the "PRIMARY" "SECONDARY" and "MIDDLE" buttons.
node.setOnMousePressed(new EventHandler<MouseEvent>() {
@Override public void handle(MouseEvent mouseEvent) {
System.err.println("mouse button: " + mouseEvent.getButton());
}
});
If I use this java application [URL] .... it is also possible to throw events for the next or previous mouse buttons of the mouse. But not in my javafx application.

I have a TreeView insight TabPane
treeView.setOnMouseClicked(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent mouseEvent) {
if (mouseEvent.getClickCount() == 2 && mouseEvent.getButton() == MouseButton.PRIMARY) {
// Some action
}
}
});
For some reason when I click on a tab body I can also perform the listener action. How I can add additional statement to perform the action only if I select node?

I have my paint application, i use the following mouse event to draw my shapes (mousePressed, mouseReleased, mouseDragged). Now after the user paint a circle for example, he must be able to drag the shape; to be able to do this. i think i must again implement the different mouse Events. I have done it and the drag is not working. How can i achieve this. can we implement multiple (mousePressed, mouseReleased, mouseDragged) in the same java class??
