Type Text

[Progr4mmer]

how can i get java to enter/type text into a textbox for me once i select it(click inside it) so the cursor is there. Also how would i get it to send the enter key or other "non-text" keys.

You can determine focus with a focusListener:

final JTextField field = new JTextField(20);		
		field.addFocusListener(new FocusListener() {
			@Override
			public void focusGained(FocusEvent arg0) {
				field.setText("Enter Your Text");				
			}
			@Override
			public void focusLost(FocusEvent arg0) {
				// Do something clever	
			}
		});

and you determine if enter, f1, etc was pushed with a keyListener:

field.addKeyListener(new KeyAdapter() {
			public void keyPressed(KeyEvent e) {
				if (e.getKeyCode() == KeyEvent.VK_ENTER)
					// do something clever		
			}			
		});

If you want your program to automatically insert text into its Swing/AWT/Whatever Gui then, yes, use a focuslistener then simply use setText (or, if you wish to have one character at a time appear, setText in a loop with a short sleep, just make sure you don't do that on the event thread). If you are talking about having a Java Program insert text into some other program's GUI (such as a website which it sounds like what you are asking), probably not, at least not "easily", and probably not without some sort of native library and JNI. Another possibility for entering into it's own program is to use the Robot class (that will allow it to act as though there were a person sitting there and using the GUI, not just enter text in the text field) Obviously usually only useful for "demos" and/or Games (as a second player, etc).

please to OP to ignore my post, because focusListener works in this case as she/he's expected, there is one ... strange ignorance on 1st. FocuLost, value must always be greater than 1T :

ok i realize what i was asking for would be hard and the thing where it types text into itself is needed for a program i have, thanks all

[mKorbel]

hmmm, can I ask you how, because your question are vague, and which Listener type you are use for that
