示例1: handleEntryClick
import javax.swing.JTree; //导入方法依赖的package包/类
public void handleEntryClick(final MouseEvent mouseEvent) {
if (!mouseEvent.isPopupTrigger() || !(mouseEvent.getComponent() instanceof JTree)) {
return;
}
JTree treeDir = (JTree)mouseEvent.getComponent();
final TreePath path = treeDir.getClosestPathForLocation(mouseEvent.getX(), mouseEvent.getY());
if (path == null) {
return;
}
treeDir.setSelectionPath(path);
boolean hasStream;
try {
ByteArrayEditableData data = treeObservable.getBinarySource().getBinaryData();
hasStream = (data.getDataSize() > 0);
} catch (Exception e) {
hasStream = false;
}
saveStream.setEnabled(hasStream);
show(treeDir, mouseEvent.getX(), mouseEvent.getY());
}
