问题描述
我从我的主要NSWindow开启一个NSWindow。
I open a NSWindow from my main NSWindow.
DropHereWindowController *dropHereWindowController = [[DropHereWindowController alloc] initWithWindowNibName:@"DropHereWindow"];
[dropHereWindowController showWindow:nil];
我想把这个窗口停留在主窗口的顶部， DropHereWindow。然而，当打开finder（不再有焦点）我的DropHereWindow在我的主窗口后面。
I want this window to stay on top of my main window when dragging a file from the finder to that "DropHereWindow". However when opening the finder (not having the focus any longer) my "DropHereWindow" goes behind my main window.
我试过orderFront，makeKey，makeKeyAndFront但没有帮助。
我能做些什么呢？
I tried orderFront, makeKey, makeKeyAndFront but nothing helped.What can I do about it?
推荐答案
方法：
- (void)setLevel:(NSInteger)windowLevel
子类NSWindow：
Sub-class the NSWindow:
[self setLevel: NSStatusWindowLevel];
或直接使用：
[window setLevel: NSStatusWindowLevel];
可用级别：
- NSNormalWindowLevel
- NSFloatingWindowLevel
- NSSubmenuWindowLevel
- NSTornOffMenuWindowLevel
- NSModalPanelWindowLevel
- NSMainMenuWindowLevel
- NSStatusWindowLevel
- NSPopUpMenuWindowLevel
- NSScreenSaverWindowLevel
