Slider Animation And ChangeListeners?
Mar 1, 2015
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.util.Random;
import java.awt.FlowLayout;
public class Slider3 {
[code]....
The oint is to make an animation using Timer with various frames - So that's my code, but when I define the sider class, I keep getting cannot find symbol errors! I don't know what to do! Is it the change listener? My teacher never really taught us how to do it apart from Actionlistener. He said we might have to put it within an ActionListener?

I have developed JavaFx application with playback option using JavaFx Media player and slider controls. I am updating slider value using javafx mediaplayer.currentTime().addListener() method by adding Change/Invalidate listener.
While playing MP4 video, slider values are not updating (Change/Invalidate listener not getting triggered while playing video) on Mac OS(version : 10.9.1). Below is the sample code snippet.
mediaPlayer.currentTimeProperty().addListener(new InvalidationListener() {
@Override
public void invalidated(javafx.beans.Observable o) {
updateSliderValue();
}
});

I have written a drum machine using Java. Into said drum machine I list all 47 available MIDI drums. The instrument list is placed into a JPanel, along with a gridArray of checkboxes. The JPanel is then in turn added to a scrollpane. I have listed the MIDI drums in order of 'ground-up'. For example, the bass drum is generally at the bottom of most drum kits, so it is at the bottom of my MIDI drums list. Next up would be the snare, followed by the cymbals, and then by all the specialty percussives. Since most beats are started from the 'ground-up', laying to foundation, so to speak, I want the scroll bar of the scrollpane which houses the JPanel, which in turn houses the instrument list and the beat checkboxes, to be positioned, upon opening, at the bottom of the scroll pane. Nothing I have tried works. It always positions the slider somewhere in the middle of the scroll track. Below is a listing of just the buildGUI portion of the code, all the MIDI functionality has been removed to keep the size of the post to this forum down.
import java.awt.*;
import javax.swing.*;
import java.util.*;
public class BeatBoxG
{
JFrame overallOuterFrame;
JScrollPane namesAndSquares;
[code]....

I have an image that moves with arrow keys, and I want to make it appear to be moving. So, I made that image, and then another with the legs moved, to give the illusion of motion. I added it to an event
Java Code:
if (k == KeyEvent.VK_RIGHT) {
image1 = image6;
peterx = peterx + 10;
resetIt();
repaint();
} mh_sh_highlight_all('java');
But it only serves to change it once. How would I make it revert to the original frame once it is converted to the second frame (image 6)? I tried a gif but to no avail?

I want to be able to show a set of pictures that would result in a primitive sort of animation. I'd like to do something lighter than making my thread sleep. Is there a way to pause the code without pausing the thread, other than something like a for-next loop of 1 to 2000 just to take up time?

I have a JTable with 6 rows and 6 columns, i.e. 36 cells. I have 1 image-icons.. I want an animation of the image, it should just be shown in the JTable as described below.
In my following explananation: Cell[row;column]
State 1
Cell[0;0] = 1st image
Cell[remain] = empty
PAUSE
State 2
Cell[0;0] = empty
Cell[0;1] = 1st image
Cell[remain] = empty
PAUSE
State 3
Cell[0;0] = empty
Cell[0;1] = empty
Cell[0;2] = 1st image
Cell[remain] = empty
PAUSE
and so on,
Once the image hits last column, it jumps 2n row 1st cell so the animation is like a snake move of the image.
I currently got stuck loading the image 1 after another, so "transition from state_i to state_i+1"
I got confused using Thread. How can I have pause between those states (I described above).
I use the Threads somehow wrong. Any example loading images in Cells (JTable) with pause in between?

I am trying to program a slot machine and as of now, I am trying to make my slots spin and randomly stop on one of the graphics. Right now, I am having difficultly making the animation/slot stop randomly.
Previously, I tried using a randomly set timer that would cancel the execution, but the image did not appear/stop on the screen.Right now, I am using a random generator and a while to say that if it is a certain number, then stop the image.Here's what I tried:
import java.applet.*;
import java.awt.*;
import hsa.*;
import java.util.Random;
public class SlotGraphics
{
Console c;
int x = 200;
int y = -100;
[code]....

I am wondering why in the example below the opacity is interpolated from the start value to the specified keyframe value but the width is not. It just jumps to the keyframe value right on button click.
import javafx.animation.KeyFrame;
import javafx.animation.KeyValue;
import javafx.animation.Timeline;
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.geometry.Pos;

I'm trying to get my animation for my java game to move along the edges of my device. Once it hits the edge I would like it to turn and keep moving along the edges. I'm sure this is easier than I'm making it but I can't find much on this. Right now my animation moves right and goes right off the screen until the app is closed and restarted.
This is my code so far:
package com.pjf.animation;
import java.io.IOException;
import java.io.InputStream;
import android.content.Context;
import android.content.res.AssetManager;
import android.graphics.Bitmap;
[Code] .....

I am looking for a way to find a resize animation for an application I'm developing. I found this answer but I figure there could be a better method out there,
Java - How do I create a Resize animation for JavaFX stage? - Stack Overflow
I am just looking to select something in a list, then press a button which would enable the animation and enlarge the stage. This will happen twice.

I have a problem with this ascii animation program I am working on. I declared a method inside of my class AsciiAnimation extends JFrame implements ActionListener, called
package AsciiAnimation;
import java.awt.*;
import java.awt.event.*;
import java.util.ArrayList;
import javax.swing.*;
public class AsciiAnimation extends JFrame implements ActionListener{
int currentFrame = 0;
ArrayList<String> frameList = new ArrayList<String>();
[Code] ....
Basically I just am trying to figure out how java works with me accessing those 2 data members, currentFrame and frameList inside of my first class ALL in the same package.
