I am about to start working on application that runs in the background waiting for a certain user input somewhat like apple's spotlight. Basically the user will give the service a certain key that will bring it up (for example the user might hit control-space or control-p) then the application main GUI will be brought up. Now my questio...
The adobe documentation says that when listening for a keypress event from a phone you should listen for Key.Down, however when I trace the Key.getCode() of keypresses I see a number not the string "Key.Down". I am tesing this locally in device central and do not have a phone to test this with at present. Here is my code - keyListener =...
I would like to write a program which can monitor activity of my keyboard. In more details, the Java program should "see" which key is pressed/released and when. All this information should be stored in a given file. First of all I would like to know if it's possible to do it with Java. I know that it's possible if I type in a text fiel...
Hi. I got a JTextField, and to that field I have added a Keylistener. Inside the keyPressed method, I ask the method to print (System.out.println) whats inside the JTextField.. If I hit a letter, it seems as the Keylistener receives this key-hit before the JTextField is updated.. I have to hit two letters to see the first one.. All I ne...
Can you have a keylistener in a java console application without messing with JNI? Will jcurses do this for me (I couldn't find it in my searching.) Thank you. ...
I am stuck in implementing the following: User starts typing in a textbox. The javascript on page captures the first character typed, validates that it is an english alphabet (a-z,A-Z) and converts it to lowercase (if necessary). Make an XMLHttp request based on the input (i.e. if first input character is a, get a.xml, if b get b.xml a...
Hi everyone, is there any conventional way in swing of tracking down the events, when two keyboard keys are pressed at the same time? I have a couple of ideas e.g. remembering the key and event generation time so that we could in a consecutive event handler invocation check the time difference between these two events and decide, whethe...
After I use my textfield I can't get a jpanel that click on back into focus for my keylistener. It works for the mouselistener but all other keystrokes keep being detected by the textfield not the jpanel. The panel has been setFocusable(true) and works fine until i give the textfield the keyboard focus. It's like the textfield won't rel...
I'm working on a map editor for my college project. And I had a problem that the map panel is not listening key event while it should. This happens when I add a ToolBarPane (which extends JPanel) with JComponent such as JButton, JComboBox that implements ActionListener on it AND the map panel (which extends the JPanel) together on to the...
In my apllication i am using a jpanel in which i want to add a key listener. I did it. But it doesnot work. Is it because i am using a swingworker to update the contents of the panel every second. Here is my code to update the panel RenderedImage image = ImageIO.read(new ByteArrayInputStream((byte[]) get())); Graphics graphics...
I have a JFrame which contains a JApplet. There are shortcut keys that I have configured for the JFrame that work fine when the focus is on some panel of it, but once I click into the applet, none of the shortcut keys work anymore. Is there any way that I can forward these key presses to the JFrame so that the events are still fired? ...
I have a search dialog with a JTextField that's being used as a search box. When the user types something, it searches the DB, shows the result in a JTable and selects the first item in it. If the first result is what they were looking for, I want to let them quickly accept the dialog, by pressing Enter (while the JTextField is focused...
Hello everyone, In Java, I am adding a KeyListener to a JWindow, but it is not getting any key events. If I used the same code but extend a JFrame instead, then everything works fine. public class MyWindow extends JWindow { ... ... private void initComponents() { ... ... addKeyListener(new KeyListene...
How can I know when the key typed change my text? Or if the key is a char? ...
I'm writing a Java application that will have an on-screen number pad available for touch-input. Normal key input will also be available, but I'd like the keypad there for tablets and such. I've made a class that extends JPanel. It has 10 buttons laid out in the normal keypad configuration. Now I'm trying to figure out how to make it ...
Hi All, I've written an app with a simple textbox which attempts to identify a user from their typing habits (interval between key presses, duration key is held, time between key strokes ie a->s is quicker than a->v for some users, shorter for others depending on typing style). It's far from perfect but it does correctly identify modera...
Here is my code, what i'm trying to do is to move that rectangle with a key press. Questions - how do i specify it on arrow keys and why it won't allow me to work it that way? It underlines my paddle object in red in KeyPressed event and won't run. import acm.graphics.*; import acm.program.*; import java.awt.event.*; public class Brea...
Anyone has experiences about interfacing with multimedia [or Fn Function] keys in Java? There seems to be an incomplete discussion regarding multimedia buttons in Java here. There is also a library, JIntelliType, which can be used to register global hotkeys in Windows, but only works for registering globally, not media keys. ...
I haven't had any luck with the web as far as this is concerned, the closest I've come is to read up on the EventQueue, but I can't seem to find a way remove an event by default. I've overloaded a JTextField so that it displays the remaining characters in a "guessed" word (part of an auto complete component) and when "Enter" is pressed ...
I keep getting the same error when I try to run my program and press a key. The error indicates the problem is in the keyTyped function, but it looks good to me. What do you think? Code: //Key Listener. private class GameKeyListener implements KeyListener { public void keyTyped (KeyEvent event) { char inputKey = 'd'; if(isStart ...
