cocoa - Pragmatic way of handling mouse in Core Animation layers -

-

I am starting to work with core animation and I wonder how different types

  1. Mouse CALayer
  2. Exclude a CALayer
  3. For now on CALayer

for now I'm focusing on the mouseDown message sent to my custom view as per the documentation. On a set with your original layer ( [customView setLayer: rootLayer] -HitTest: (CGPo Int should be called.

It should return the front layer in the tree which is in the position specified by the point. So I did this: 

  [Routehere Hit Test: [Event Location In Windows]]

But that does not work. It seems that if I just click on RouteLayer Otherwise, it just gives null , of course the subliders are added to the root layer (in fact they are ready) Te)

What am I missing coordinate conversion of some sort? Also, is this a way to handle mouse clicks?

Whenever a mouse enters the cell, then do I have to keep the hit test for every movement of the mouse update?

Thanks in advance

You can see how we can mouse / Handle touch events. We have established a rational response chain with our various CALayer subclasses in the layer hierarchy. Recently we used code to scroll a graph using mouse / touch events as an example of using this type of interaction.

I have used myself like this in a similar way, only in the view of the main layer-hosting view that handling mouse clicks, I have added a code like overload -massdown: and the following:

CGPETE pointOfClique = NSPNTOCGpoint ([Self ConvertPoint: [Avent Location Invocation] SEVUE: NILE)); CALayer * hitLayer = [self.layer hit test: pointoffClick]; If ((Hitlayer! = Void) & [Hitler Hackinduff Class: [MightyLawyer Class]]) [[(Macstallier * Hittler MouseDown]; }

The MyCustomLayer class will be a custom CALayer subclass that responds to the mouseDown method and clicks on some of its own control over the mouse. Alternatively, you can see this from your layer-hosting view. Within the method can fully handle the mouse click response.

One thing to make sure is that if you subclassed CALayer, its ContainsPoint: method still gives yes if the passed point is located within the bounds of your layer, otherwise - Ittest: will ignore that layer.

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
