示例1: usableKeyOnMac
private static boolean usableKeyOnMac(int key, int mask) {
//All permutations fail for Q except ctrl
if (key == KeyEvent.VK_Q) {
return false;
}
boolean isMeta = ((mask & KeyEvent.META_MASK) != 0) || ((mask & KeyEvent.CTRL_DOWN_MASK) != 0);
boolean isAlt = ((mask & KeyEvent.ALT_MASK) != 0) || ((mask & KeyEvent.ALT_DOWN_MASK) != 0);
boolean isOnlyMeta = isMeta && ((mask & ~(KeyEvent.META_DOWN_MASK | KeyEvent.META_MASK)) == 0);
//Mac OS consumes keys Command+ these keys - the app will never see
//them, so CTRL should not be remapped for these
if (isOnlyMeta) {
return (key != KeyEvent.VK_H) && (key != KeyEvent.VK_SPACE) && (key != KeyEvent.VK_TAB);
}
if ((key == KeyEvent.VK_D) && isMeta && isAlt) {
return false;
}
if (key == KeyEvent.VK_SPACE && isMeta && ((mask & KeyEvent.CTRL_MASK) != 0)) {
