示例1: setCursor
import sun.awt.SunToolkit; //导入方法依赖的package包/类
protected void setCursor(Component comp, Cursor cursor, boolean useCache) {
if (comp == null) {
return;
}
Cursor cur = useCache ? cursor : getCapableCursor(comp);
Component nc = null;
if (useCache) {
synchronized (this) {
nc = nativeContainer.get();
}
} else {
nc = SunToolkit.getHeavyweightComponent(comp);
}
if (nc != null) {
ComponentPeer nc_peer = AWTAccessor.getComponentAccessor().getPeer(nc);
if (nc_peer instanceof XComponentPeer) {
synchronized (this) {
nativeContainer = new WeakReference<Component>(nc);
}
//6431076. A subcomponents (a XTextArea in particular)
//may want to override the cursor over some of their parts.
((XComponentPeer)nc_peer).pSetCursor(cur, false);
// in case of grab we do for Swing we need to update keep cursor updated
// (we don't need this in case of AWT menus). Window Manager consider
// the grabber as a current window and use its cursor. So we need to
// change cursor on the grabber too.
updateGrabbedCursor(cur);
}
}
