Im making a bot for my friend who is on twitch, and he forgets to switch from his "brb" scene to his "game" scene on xsplit, so he wanted to make something where the mods could change or control somethings on his computer if he forgot. it was easy making a bot for that.
The code was easy to make and it is like this.
import java.awt.Robot;
import java.awt.event.KeyEvent;
import org.jibble.pircbot.*;
public class Twitchbot extends PircBot {
public Twitchbot() {
this.setName("Rex__Bot");
}
public void onMessage(String channel, String sender, String login, String hostname, String message) {
if(message.equals("Something")) {
try {
Robot r = new Robot();
r.keyPress(KeyEvent.VK_Something);
r.delay(300);
r.keyRelease(KeyEvent.VK_Something);
}catch(Exception ex) {
ex.printStackTrace();
}
}
}
}
And i was wondering if there was a way to make a GUI to change the Letter that the message equals to and the keyevent.VK_Something to something different with the GUI so it would be easy for him to edit it.
So, to start with, you need some way to capture the information you want. Basically, you need the message and the keystroke. The keystroke consists of the virtual key and the modifiers.
The following example basically provides a means by which the user can type a message text and a key stroke. The capture pane uses a KeyListener to monitor for key events and by extract various values from the key event, will store the information it needs and displays the key character to the user.
You can the save this information to a Properties file which you can later load...

You then need to load the Properties file and create a new KeyStroke...
Properties p = new Properties();
try (InputStream is = new FileInputStream(new File("Config.cfg"))) {
p.load(is);
String name = p.getProperty("name");
int keyCode = Integer.parseInt(p.getProperty("keyCode"));
int modifiers = Integer.parseInt(p.getProperty("modifiers"));
KeyStroke ks = KeyStroke.getKeyStroke(keyCode, modifiers);
System.out.println(ks);
} catch (IOException exp) {
exp.printStackTrace();
}

This is the code I checked about the default text prompt function of JTextField but I don’t know where it should be placed or used
import java.awt.Color;
import java.awt.event.FocusEvent;
import java.awt.event.FocusListener;
import javax.swing.JTextField;
public class JTextFieldHintListener implements FocusListener {
private String hintText;
private JTextField textField;
public JTextFieldHintListener(JTextField jTextField,String hintText) {
this.textField = jTextField;
this.hintText = hintText;
jTextField.setText(hintText); //默认直接显示
jTextField.setForeground(Color.GRAY);
}
#Override
public void focusGained(FocusEvent e) {
//获取焦点时，清空提示内容
String temp = textField.getText();
if(temp.equals(hintText)) {
textField.setText("");
textField.setForeground(Color.BLACK);
}
}
#Override
public void focusLost(FocusEvent e) {
//失去焦点时，没有输入内容，显示提示内容
String temp = textField.getText();
if(temp.equals("")) {
textField.setForeground(Color.GRAY);
textField.setText(hintText);
}
}
}
this code is only allowing me to reject a string the second time to try to drop in a textArea where there is all ready a string.
public GridLayoutTest() {
JFrame frame = new JFrame("GridLayout test");
connection = getConnection();
try {
statement = (PreparedStatement) connection
result = statement.executeQuery();
while (result.next()) {
byte[] image = null;
image = result.getBytes("image");
JPanel cellPanel = new JPanel(new BorderLayout());
cellPanel.add(cellLabel, BorderLayout.NORTH);
cellPanel.add(droplabel, BorderLayout.CENTER);
gridPanel.add(cellPanel);
}
}
catch (SQLException e) {
e.printStackTrace();}
}
So, two things, first...
public void DropTargetTextArea(String string1, String string2) {
Isn't a constructor, it's a method, note the void. This means that it is never getting called. It's also the reason why DropTargetTextArea textArea = new DropTargetTextArea(); works, when you think it shouldn't.
Second, you're not maintaining a reference to the values you pass in to the (want to be) constructor, so you have no means to references them later...
You could try using something like...
private String[] values;
public DropTargetTextArea(String string1, String string2) {
values = new String[]{string1, string2};
DropTarget dropTarget = new DropTarget(this, DnDConstants.ACTION_COPY_OR_MOVE, this, true);
}
And then use something like...
if (values[0].equals(dragContents) || values[1].equals(dragContents)) {
In the drop method.
In your dragEnter, dragOver and dropActionChanged methods you have the oppurtunity to accept or reject the drag action using something like dtde.acceptDrag(DnDConstants.ACTION_COPY_OR_MOVE); or dtde.rejectDrag();

I am trying to get this SwingWorker to function correctly. However,the variables that need to be accessed seem to be not global. What do I do? I tried adding static but it creates more errors and complications later about accessing static from non static. The variables that are not working in the SwingWorker are the LOCAL_FILE and URL_LOCATION variables.

Your program is mostly a huge static main method. You're kind of getting the cart in front of the horse trying to do advanced programming such as with SwingWorker before first creating clean OOP code. In other words -- start over and do it right. Then the connections between classes will be much more natural and it will be much easier to get things to work right. The main method should only concern itself with starting the Swing event thread, creating a GUI object in that thread, and displaying it. Everything else should be in classes that create objects.
Also, on a more practical level, you have yet to tell us what variables are causing you trouble or what errors you might be seeing. Also, where are you trying to create and execute the SwingWorker?
Edit
One tip that will likely help: Give your SwingWorker class a constructor, and pass important parameters into your SwingWorker object via constructor parameters. Then use those parameters to initialize class fields that will be used in the SwingWorker's doInBackground method.
e.g.,
class DownloadWorker extends SwingWorker<Integer, Integer>
{
private String urlLocation;
private String localFile;
public DownLoadWorker(String urlLocation, String localFile) {
this.urlLocation = urlLocation;
this.localFile = localFile;
}
protected Integer doInBackground() throws Exception
{
try {
URL website = new URL(urlLocation);
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = new FileOutputStream(localFile +"\\ProfessorPhys.iso\\");
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
System.out.println("--------\nDone Downloading\n---------");
} catch (Exception e) {
System.err.println(e);
}
return 42;
}
protected void done()
{
try
{
System.out.println("done");
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
I want to get the event like crtl+c or right click copy in windows , that could do the event to java application running ,
that means if someone copies some text , that should be pasted into the java application textarea...
i have made the java application and it can accept arguments through main method.
but how to trigger event from windows to java..
The simplest way is to monitor changes to the Toolkit.getSystemClipboard
There are two ways to do this. You can monitor changes to the DataFlavour, but this will only help if the data flavor changes, not the content and/or you could monitor the contents of the clipboard and update your view when it's content changes...

I've been wondering if for example:
JTextPane chatTextArea = new JTextPane();
s.replaceAll(":\\)", emoticon());
public String emoticon(){
chatTextArea.insertIcon(new ImageIcon(ChatFrame.class.getResource("/smile.png")));
return "`";
}
can put a picture and a "`" everywhere ":)" is found. When I run it like this if s contains a ":)" then the whole s gets replaced just by the icon.
Is there a way to do it?
Here is a small example I made (+1 to #StanislavL for the original), simply uses DocumentListener and checks when a matching sequence for an emoticon is entered and replaces it with appropriate image:
NB: SPACE must be pressed or another character/emoticon typed to show image
