iphone - Getting a view to respond to a sibling's touch event / message -

-

I'm sure that's the right way to do this, I'm new to touching Objective-C and Coco so I Do not know what is there.

I have an application that has a (simplified) visual hierarchy 

  window - button - button - vishwu - sub-subview

What am I trying to do, is receiving a review to do something in response to a touch event on one of the buttons. I can come up with some ways of doing this, but I'm not sure which is the preferred method.

  • Add an outlet for the menu view controller (handle window) and store the reference of the subview. When I need to send a message to the subview, then I can just pass the message that I want (because I already have a reference). It seems a little bit ... delicate?

  • Add another action on the button (the first view is a method on the controller, the second one will be on the subview class) it looks problematic because it is important that the view controller is in the fire The action of the button earlier tries to handle the sub-message

  • Some types of representative systems?

  • Write a new view controller for the subview and that message passes the main view controller (not sure that the first controller is right for its In addition, the actual code needed for the subview is relatively small - a new controller looks like Overkill).

  • Something else is that I '

Some direction would be appreciated!

You say that there is an action on the view controller in the button (seeing the controller?). And you want to call action / method on the subview that happens after that action. Therefore, I will suggest my visual controller action after a notification of the incident, and the subclass can listen to that event. Alternatively, the view controller can have a connection with a subview.

It ensures the sequence of verbs - most observational techniques will not ensure that order.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

Visual Studio 2005: How to speed up builds when a VSMDI is open? -

-
Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

booting ubuntu from usb using virtualbox -

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never
