CGWindowListCopyWindowInfo, kCGWindowLayer and window level

限于喜欢 提交于 2019-12-04 10:49:33
The CGWindowLevel.h file defines the constants that are used to set the window level and the largest value that can be used as window level is 20. But, if you retrieve the window list using the call CGWindowListCopyWindowInfo , you can observe that the value of kCGWindowLayer is more than 20 (25, 103 etc). Aren't kCGWindowLayer and window level same? If they are not same, how do I get the window level for the windows that are obtained using CGWindowListCopyWindowInfo ? If they are same, why do we get value >20? It appears that kCGWindowLayer does refer to a window level, though I haven't found

Trying to delay CABasicAnimation position and opacity of layer by 3 seconds but

纵然是瞬间 提交于 2019-12-04 10:35:29
问题 I am trying to delay the animation of layer's opacity and position by 3 seconds using setBeginTime. I have called the layer boxLayer. The animation is going well however during the first 3 seconds (the layer is not supposed to show yet) the layer is displayed at its final position and opacity. It should not. Group animation does not resolve the issue. Could anyone help? See code below: // Create an animation that will change the opacity of a layer CABasicAnimation *fader = [CABasicAnimation

DDD - which layer DTO should be implemented

删除回忆录丶 提交于 2019-12-04 10:01:25
问题 I am learning about DDD so apologies if my question is naive. I think I need to use Local Data Transfer Object in order to display data to the users as a lot of properties are not part of any of Entity / Value Objects. However, I am not sure where this DTO should be implemented - in a Domain Layer or in an Application Service Layer. The DTO implementation seems part of the Domain, but it means that when I create a collection of DTOs in the Service Layer and pass it to a Presentation Layer, I

Grails - the use of service layer

妖精的绣舞 提交于 2019-12-04 04:57:06
I have problems in organizing my code when I want to update a non-simple domain object. The problem is to separate responsibilities for the controller and the service layer. More explicitly, assume that we have a domain class Client that depends on other domain classes like Address and so on. In the view there is a gsp for editing some of the Clients properties including some of the nested properties like street on the Address. When I would like to update those fields I call the update method on a Controller (in this case the ClientController). I like the feature coming from the errors of a

Where to define the interfaces for a repository in an layered architecture?

假如想象 提交于 2019-12-04 02:13:39
Background I'm trying to create a simple application to really understand the whole stack of DDD+TDD+etc. My goal is to dynamically inject the DAL repository classes at runtime. This keeps my Domain and Application Services layers testable. I plan on using "poor man's DI" to accomplish this for now ... so I would do this in a simple Console application near startup: // Poor man's DI, injecting DAL repository classes at runtime var productRepository = new SimpleOrder.Repository.ProductRespository(); var customerRepository = new SimpleOrder.Repository.CustomerRepository(); var orderRepository =

Best way to develop service layer in java [closed]

本小妞迷上赌 提交于 2019-12-03 21:29:54
Closed . This question needs to be more focused. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it focuses on one problem only by editing this post . Closed 5 years ago . I wants to develop service layer for my application using java. At the same time the service layer can also be exposed to webservice also. My idea is to create one Generic Abstract Class for database operations , and all other service classes extend that abstract class and do the DB operation through that abstract class methods. Is this a good idea to do it? Please

Disable Implicit Animation of CATextLayer.string Property

房东的猫 提交于 2019-12-03 16:27:57
I have a view with one sublayer of type CATextLayer. I override the views drawRect: method and in there change the CATextLayer.string property to an instance of NSAttributedString. Each time the NSAttributedString has the same text but with different colors. As of now each time the string property changes, the text color makes an animated transition into the new color. Is there any way I can disable the animation of this property? Antoni Figured it out, using the answer for this question: Disabling implicit animations in -[CALayer setNeedsDisplayInRect:] In my particular case, to stop the
