Using OpenGL on QT without the wrappers [closed]

Closed. This question is off-topic. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I'm looking for a GUI toolkit to use in conjunction with OpenGL. QT looks promising but unfortunately it wraps most OpenGL functions in QT classes. Is there any way for me to create an OpenGL 3.3 context in QT and just use the standard C API? There's no need for you to use most of the QT specific OpenGL classes. You need the QGLWidget context itself, something to tell QT when to repaint the widget

Wrapping request parameters using HTTPServletRequestWrapper

由 自闭症网瘾萝莉.ら 提交于 2019-12-04 11:07:58
I have a filter that authenticates/authorizes REST calls. This filters needs to access the request parameters so I have written a custom HTTPServletRequestWrapper for this. import java.util.Collections; import java.util.Enumeration; import java.util.HashMap; import java.util.Map; import javax.servlet.ServletRequest; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletRequestWrapper; public class WrapperRequest extends HttpServletRequestWrapper { private Map<String, String[]> requestParams = null; public WrapperRequest(final ServletRequest request) { super(

R: Advantages of using a Fortran subroutine with .Call and C/C++ wrapper instead of .Fortran?

由 ╄→гoц情女王★ 提交于 2019-12-04 10:03:17
问题 I have an R package which uses lots of Fortran subroutines for nested loops of recursive linear algebra computations (depending heavily on BLAS and LAPACK routines). As an interface to Fortran, I use .Fortran function. I just read Jonathan Callahan's blog post about using .Call instead of .C in case of subroutines written in C/C++, and it got me thinking that would it be better to use .Call interface also when using Fortran subroutines, by writing a simple wrapper in C which then calls the

Are all primitive wrapper classes immutable objects?

问题 Are all primitive wrapper classes in Java immutable objects? String is immutable. What are the other immutable objects? 回答1: Any type which doesn't give you any means to change the data within it is immutable - it's as simple as that. Yes, all the primitive wrapper types are immutable 1 , as is String . UUID, URL and URI are other examples. Although Calendar and Date in the built-in Java API are mutable, many of the types within Joda Time are immutable - and to my mind, this is one reason why

How to use a C++ project from within a .NET application?

由 陌路散爱 提交于 2019-12-04 08:46:45
I'm a regular .NET developer aiming to integrate a C++ library into a .NET project. I have a few ideas, but since I'm new to C++ in general I don't know the limits of the technology I'm trying to work with. The C++ project is essentially a fast sound renderer that can playback multi-track audio files with a bunch of different postprocessing tricks. All of this is cool, but considering I have a simple .NET WinForms app I want to integrate with, things start to look messy. Firstly, the C++ project has no .NET bindings or ActiveX/COM integration. Its a plain 'ol MS VC++ 9 project. If I am to work

Python: wrap all functions in a library

由 こ雲淡風輕ζ 提交于 2019-12-04 08:19:24
We use a library provided by another internal team. (Shaky analogy starts now) from externalTeam import dataCreator datacreator.createPizza() datacreator.createBurger() datacreator.createHotDog() Recently we found a single method of theirs was taking over a minute to execute in certain situations. To debug this, I had to go into our code and add timeouts around every call of this method. import time from externalTeam import dataCreator start = time.clock() datacreator.createPizza() stop = time.clock() print "It took %s seconds to perform createPizza" % (str(stop-start)) In hindsight, that's

Is there a C header parser tool for wrapper generation like gccxml?

由 烂漫一生 提交于 2019-12-04 07:05:41
I need to write a few c header wrappers for a new programming language and would like something like gccxml but without the full dependency on gcc and the problems it gives on a windows system. Just needs to read C not C++. Output in any format is okay as long it is fully documented. Need it for Curl, SQLite, GTK2, SDL, OpenGL, Win32 API and C posix API's on Linux/Solaris/FreeBSD/MacOSX. VivaCore is very cool. Have you tried SWIG the wikipedia page on ffi has some good links too. I think there is a MSVC codedom example that does C also. See our SD C Front End for DMS .

Wrapping an Unmanaged C++ Class Library with C++/CLI - Question 2 - Collections

由 拜拜、爱过 提交于 2019-12-04 06:03:08
Note: This post represents Question #2 of my inquiry. The introduction block (all text until the numbers are reached) is repeated in both questions as it is background information that may be needed to answer the question. Introduction to Question I have an unmanaged C++ library that contains classes and functions that are common to and shared among several "higher level" libraries. I now have need to provide access to the common library to C#/.Net applications. To do this, I will have to wrap the common library with C++/CLI wrapper classes. The classes contained in the common library can be

HikariCP Wrapper (thread safety)

由 [亡魂溺海] 提交于 2019-12-04 05:56:59
问题 I'm learning to use HikariCP (i'm new in java) and i found a wrapper but i think it's not thread safety, well the instance of the singleton is thread safety but not the method getConnection(). The class is this: public class HikariCPWrapper{ private static final HikariCPWrapper INSTANCE; private HikariDataSource ds; static { INSTANCE = new HikariCPWrapper(); } private HikariCPWrapper(){ HikariConfig config = new HikariConfig(); //config.set... //... ds = new HikariDataSource(config); } public

Wrapper C# for kernel32.dll API

Any helper class anywhere which wrapps kernel32 APIs, with all functions-methods and structures? Or any wrapper generator? I want ALL methods of kernel32.dll in C# like this: [DllImport("kernel32.dll",EntryPoint="RtlMoveMemory")] public static extern void RtlMoveMemory(int des, int src, int count); [DllImport("kernel32.dll", EntryPoint = "OpenProcess")] public static extern IntPtr OpenProcess(uint dwDesiredAccess, bool bInheritHandle, uint dwProcessId); [DllImport("kernel32", CharSet = CharSet.Ansi)] public extern static int GetProcAddress(int hwnd, string procedureName); [DllImport("kernel32
