示例1: getTextLocation
import java.awt.im.InputMethodRequests; //导入方法依赖的package包/类
public Rectangle getTextLocation(TextHitInfo offset) {
synchronized (compositionAreaLock) {
if (compositionAreaOwner == this && isCompositionAreaVisible()) {
return compositionArea.getTextLocation(offset);
} else if (composedText != null) {
// there's composed text, but it's not displayed, so fake a rectangle
return new Rectangle(0, 0, 0, 10);
} else {
InputMethodRequests requests = getClientInputMethodRequests();
if (requests != null) {
return requests.getTextLocation(offset);
} else {
// passive client, no composed text, so fake a rectangle
return new Rectangle(0, 0, 0, 10);
}
}
}
}
示例2: updateWindowLocation
import java.awt.im.InputMethodRequests; //导入方法依赖的package包/类

* Positions the composition window near (usually below) the
* insertion point in the client component if the client
* component is an active client (below-the-spot input).
