示例1: accept
import java.awt.Component; //导入方法依赖的package包/类
private boolean accept(Component aComponent) {
if (!(aComponent.isVisible() && aComponent.isDisplayable() &&
aComponent.isFocusable() && aComponent.isEnabled())) {
return false;
}
// Verify that the Component is recursively enabled. Disabling a
// heavyweight Container disables its children, whereas disabling
// a lightweight Container does not.
if (!(aComponent instanceof Window)) {
for (Container enableTest = aComponent.getParent();
enableTest != null;
enableTest = enableTest.getParent())
{
if (!(enableTest.isEnabled() || enableTest.isLightweight())) {
return false;
}
if (enableTest instanceof Window) {
break;
