detecting SHIFT / CTRL / Arrow keys?
« on: Apr 25th, 2003, 5:40pm » |

on my p5 0054 / win2k / JRE1.4.x, the "key" variable is returning 65535 when i press SHIFT, CTRL or one of the arrow keys...
but i badly need to detect them!
doctor, is it normal? is there a cure to this?

saddling P5 0054 / WINMX / JRE1.4.1x, i discovered them with this code:
Code:
public void keyPressed(KeyEvent e) {
println(e); // shows whole info on the pressed key
println(e.getKeyCode()); // shows keyCode
int myKey = e.getKeyCode();
if (myKey == 10) {
... code ...
}
}

btw, it gives me:
LEFT = 37;
RIGHT = 39;
UP = 38;
DOWN = 40;
CTRL = 17;
ALT = 18;
SHIFT = 32;
NOTE: since it catches the key being pressed, if you use switch, don't forget to add a break; after the action, if not, it continues catching it ad infinitum...

alternatively, you can also get the name of the key pressed via:
public void keyPressed(KeyEvent e) {
println(e.getKeyText(e.getKeyCode()) );
}
if you want to find out, if shift/control/alt is still pressed in conjunction with another key, use these methods of the KeyEvent (all return true/false):
e.isShiftDown()
e.isControlDown()
e.isAltDown()

We are adding a variable called "keyCode" which will make it easy to trap for special keys.

this has been implemented for 0056 for UP, DOWN, LEFT, RIGHT, ALT, CONTROL, and SHIFT.
Code:void keyPressed()
{
if (key == UP) {
println("up");
} else if (key == DOWN) {
println("down") {
} else {
println("around");
}
