What is the VK_[key] code for the command key on a mac, if one exists? I am trying to get a Robot (java Robot) to press the command key. I am using the command keyPress(), and I need to know the integer keycode for the command key on a mac. KeyEvent.VK_META , with key code 157 , is Java's virtual key that maps to the the Mac command key. 来源： https://stackoverflow.com/questions/15418987/java-robot-keypress-command-key

How do you get the VK code from a char that is a letter? It seems like you should be able to do something like javax.swing.KeyStroke.getKeyStroke('c').getKeyCode() , but that doesn't work (the result is zero). Everyone knows how to get the key code if you already have a KeyEvent, but what if you just want to turn chars into VK ints? I'm not interested in getting the FK code for strange characters, only [A-Z],[a-z],[0-9]. Context of this problem -------- All of the Robot tutorials I've seen assume programmers love to spell out words by sending keypresses with VK codes: int keyInput[] = {

I'm working on a game in Java and have the following challenge. I have 2 JPanels and need to visually drag shapes from one JPanel to another. I've got this working using the GlassPane from the JFrame . When I press the mouse to drag a shape, the GlassPane activates and transfers the shape to the glassPane. Because of this you need to transfer the mousePressed state from the JPanels mouseAdapter to the glassPanes mouseAdapter . I solved this by using the Robot Class which simulates another mousePressed event after the glassPane has been acivated. Now here comes the problem, this workaround only

Currently i'm trying to have java hold down a key like follows: Robot rob; rob.keyPress(KeyEvent.VK_ENTER); Thread.sleep(3000); rob.keyRelease(KeyEvent.VK_ENTER); This should hold enter down for 3 seconds, causing the repeating effect after a second or so. In other words, if you were to manually hold the "r" key, it would first type r, and then after about a second it would go like rrrrrrrr. I want this effect from the robot. I also tried: curTime = System.currentTimeMillis(); while(System.currentTimeMillis() - curTime < duration) { rob.keyPress(whatever); } rob.keyRelease(whatever); This,

How exactly does the method getPixelColor(int x,int y) from the Robot class work? I tried this code fragment: try { Robot robos = new Robot(); } catch (AWTException e) { } for (int i = 0; i < 100; i++) robos.getPixelColor(0, 0); System.out.println("fsadf"); on my PC, which is a core 2 duo, and it took one second or less to execute the print statement. However, when I ran this same code on my laptop, which is a core i3, it took much more time (about 2-3 seconds). What is the reason behind this? Does it have to do with the screen quality or something like that? How can I solve this problem? how

I'm working on a system to type things automatically with java. This is how I write it: public void typeMessage(String message) { for (char c : message.toCharArray()) { int code = c; if (code > 96 && code < 123) code = code - 32; if (c == '@') { robot.keyPress(VK_SHIFT); robot.keyPress(VK_AT); robot.keyRelease(VK_SHIFT); robot.keyRelease(VK_AT); } else { type(code); } } type(VK_ENTER); } But I'm getting this error: Exception in thread "Thread-2" java.lang.IllegalArgumentException: Invalid key code on robot.keyPress(VK_AT); Your keyboard layout should have a key for the @ symbol for this code

I am trying to create a program that automatically searches for a text field on the screen and types a word repetitively into that text field. Is there any class that can find a text field? Or is there any way in which a text field can be found? Because I know that the Robot class can type text, I just need to either get the cursor onto the text field and use the mousePress() and mouseRelease() methods. Thanks Alex Lynch I can't directly give you a solution, but I messed around with some code and may be able to point you in the right direction. Java, as you probably know, runs in the JVM. This
