NSWindow隐藏活动窗口并专注于其他窗口

Question

如何隐藏当前活动的NSWindow A 并关注最后一个 B （当前窗口后一级）并将其激活？

我尝试使用此跟踪代码，但它不起作用（ B 将变为前窗但未激活）：

[_parentWindow orderBack:nil];
// Now i want to do some stuffs with last opened App (NSWindow) and it should be focused and activated now. 
[_parentWindow orderFront:nil];

Answer 1

请尝试makeKeyAndOrderFront:。

[_window makeKeyAndOrderFront:nil];

@bluedome响应的补充。您可以在当前用户会话中获取有关Windows的信息：

CFArrayRef windowList = CGWindowListCopyWindowInfo(kCGWindowListOptionOnScreenOnly, kCGNullWindowID);
for (NSDictionary* entry in (__bridge NSArray *)windowList) {
  NSString *ownerName = [entry objectForKey:(id)kCGWindowOwnerName];
  NSInteger ownerPID = [[entry objectForKey:(id)kCGWindowOwnerPID] integerValue];
  NSString *windowName = [entry objectForKey:(id)kCGWindowName];
  NSLog(@"%@:%ld, %@", ownerName, (long)ownerPID, windowName);
}
