问题 I was using Qt Creator and I decided I wanted to document a function I had written so I positioned my cursor above my function definition and typed /**<ENTER> like so: /**<ENTER> void MyClass::myFunction(int myArg) { ... Qt Creator auto-expanded that comment: /** * @brief MyClass::myFunction * @param myArg */ void MyClass::myFunction(int myArg) { ... What is this? Where is it documented? Can I use this to generate my own Qt Assistant qch help files or something? 回答1: It should be documented

问题 I am developing a application using Qt, the C++ library/framework. Using the QT-Creator I can compile my project just fine and the build directory generates the desired executable files just fine. However, I am trying to automate my asks and using Apache ANT. But I am running into the following issues. Here is the output from the command line: build.mac.64: [echo] Building for Mac [echo] Updating destination path [exec] Project WARNING: No .qmake.cache is present. This significantly slows

问题 I have compiled TBB from source using Mingw following the comment #5 in this post: http://software.intel.com/en-us/forums/topic/291331. That went ok. When I try to use the new TBB library in a QtCreator project, I end with this errors (ignore the warning messages): http://postimage.org/image/yrrecugix/ Here's the sample code I tried (I omit the non-tbb code): #include "tbb/task_scheduler_init.h" int main() { tbb::task_scheduler_init init; /// more things. } And here's the .pro file: TEMPLATE

问题 So when I create a new Qt project inside Qt Creator I'm only asked for some simple details like location of the project, build targets, the main window class name (along with header, source and form file) and at the enda choice to add it to version control. After I create the project I'm only given the qt core and gui modules. My question is how do I add other modules (such as network or opengl). I've looked and looked, yet I cannot find anything on how to add other Qt modules easily. I know

问题 I am trying to include the pre-compiled (MSVC2012) OpenCV static libraries into Qt Creator but I am unsure what the include path is about as per this image: Here is an image of the precompiled OpenCV files that I downloaded: There are 3 directories: bin contains DLLs, lib contains small lib files (2 kb) so that QtCreator can understand the DLLs, and staticlib containts large lib files (1 mb) which are the static libraries that I'm trying to link against. The library file/path is something
