containers

问题 I have 3 divs on a form page of my website. The top left toggle overlaps the bottom div whenever i click the toggle button. What I'm trying to do is that the bottom left div container should move down when the top div container is clicked and move back to it's former position when toggle is closed. I have included the css for the right div, I dont know if that is the css afecting the positions of the two div 's beside it. Before Toggle After Toggle CSS for Toggle #toggle-view { list-style

问题 I wrote a class (let's call it Model.java) that contains a Deque<T> , with methods for enqueuing and dequeuing items. Now I'm trying to tie this to a GUI JList. I'm baffled by how to somehow use my "model" data -- the Deque -- as a DefaultListModel that JList wants. I'm still struggling to really get OO concepts, as they apply to GUI programming. DefaultListModel documentation states: This class loosely implements the java.util.Vector API, in that it implements the 1.1.x version of java.util

问题 I followed Istio's official documentation to setup Istio for sample bookinfo app with minikube. but I'm getting Unable to connect to the server: net/http: TLS handshake timeout error. these are the steps that I have followed(I have kubectl & minikube installed). minikube start curl -L https://git.io/getLatestIstio | sh - cd istio-1.0.3 export PATH=$PWD/bin:$PATH kubectl apply -f install/kubernetes/helm/istio/templates/crds.yaml kubectl apply -f install/kubernetes/istio-demo-auth.yaml kubectl

问题 Is there any library provide a multidimensional container to use like vector<>? I would like to see something like: TwoD<object_class_name> D2; ThreeD<object_class_name> D3; and the object_class_name could be any object instead of only the builtin types. so I can use the object like D2[i][j] D3[i,j,k] or D3(i,j,k) or similar Thanks. 回答1: If c++11, a possible solution is using which allows aliasing of a template : template <typename T> using TwoD = std::vector<std::vector<T>>; template

问题 How can I get docker's container name from inside the container? I can't use inspect because I have to use an script from inside the container to get info from a JSON url. 回答1: If you mean the Container ID its available in the env as the hostname variable. It should be interchangeable with the name for most operations. env HOSTNAME=5252eb24b296 TERM=xterm .... CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 5252eb24b296 ubuntu:14.04 "bash" 23 seconds ago Up 22 seconds test 回答2: I think,

问题 How can I substitute a container directive ? The following doesn't work: .. |sub| container:: Some text here .. image:: img/some_image.png Some other text here The error message is WARNING: Substitution definition "sub" empty or invalid. 回答1: This is not possible. ReST substitutions apply to inline text (single paragraphs), but a container is a block element. And if you try .. |sub| replace:: container:: Some text here .. image:: img/some_image.png Some other text here you will get ERROR:

问题 I have a std::list<obj*> , where obj is my class: std::list<obj*> list_of_ptr; list_of_ptr.push_back(new obj()); I want to convert this list to the equivalent std::list<obj> , after that I no longer need the list_of_ptr . What is the fastest way to do this work? 回答1: std::transform is your friend: std::vector<obj> objects; std::transform( list_of_ptr.begin(), list_of_ptr.end(), std::back_inserter(objects), [](obj* p) { return *p; }); Or, if C++11 lambda expressions cannot be used, one may use

问题 I need a container of elements that are neither copyable nor movable. These elements are not default constructible, but their constructors get identical arguments. The size of the container does not change during it's lifetime. It should be as simple as a built-in array, but it's size is determined at run-time when the constructor is called. Is there an easy way to implement that without the overhead of memory allocation and indirection incurred by using std::vector<std::unique_ptr<T>> ? 回答1:

问题 I searched a bit on google but got no useful results. I'm finishing dockerizing vim and a common problem showed up: its container just won't share the clipboard with the host. I am used to building vim with +clipboard , and to being able to yank text and have it available to the host, or copying text in host and pasting in vim... I thought about making -v volumes that would share this data but I still got nowhere. I'm on Ubuntu 16.10. 回答1: The clipboard is almost certainly part of X, so you

问题 I'd like to implement a simple native C++ fixed-capacity array template class, supporting the range-based "for each" syntax for convenience, with minimal overhead. I'm having trouble with supporting it on const instances. With this implementation: template< class T, size_t Capacity > class List { public: List() { mSize = 0; } const T* begin() const { return mItems; } const T* end() const { return mItems + mSize; } T* begin() { return mItems; } T* end() { return mItems + mSize; } private: size
