Qt Mac系统，打开文件对话框卡住现象

打开对话框后出现bug提示：
Unable to simultaneously satisfy constraints:
(
"",
"",
""
)

Will attempt to recover by breaking constraint

Set the NSUserDefault NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have -[NSWindow visualizeConstraints:] automatically called when this happens. And/or, break on objc_exception_throw to catch this in the debugger.

然后具体就这样!求

大神帮小弟看看
