I read the example in How To - Detect Alt and Shift key clicks. But after repair i have :
import net.rim.device.api.system.Characters;
import net.rim.device.api.system.KeyListener;
import net.rim.device.api.system.KeypadListener;
import net.rim.device.api.ui.Keypad;
import net.rim.device.api.ui.Manager;
import net.rim.device.api.ui.Screen;
import net.rim.device.api.ui.component.Dialog;
import net.rim.device.api.ui.container.MainScreen;
class KeyHandlerScreen extends Screen
{
// Invoked when a key is pressed.
protected boolean keyDown(int keycode, int time)
{
int key = Keypad.key(keycode);
int status = Keypad.status(keycode);
if ((status & KeypadListener.STATUS_ALT) != 0)
{
Dialog.inform("Key(" + key + ")" + "Alt");
}
else if ((status & KeypadListener.STATUS_SHIFT) != 0)
{
Dialog.inform("Key(" + key + ")" + "Shift");
}
return super.keyDown(keycode, time);
}
// Invoked when a sequence of one or more key presses
// generates a character.
protected boolean keyChar(char key, int status, int time)
{
switch (key)
{
case (Characters.ESCAPE):
if ((status & KeypadListener.STATUS_ALT) != 0)
{
Dialog.inform("Alt + ESC");
}
else if ((status & KeypadListener.STATUS_SHIFT) != 0)
{
Dialog.inform("Alt + Shift");
}
return true;
}
return super.keyChar(key, status, time);
}
protected void sublayout(int width, int height)
{
// TODO Auto-generated method stub
}
}
But i don't know how to use it and create contrustor for it. Pls help?
