• Qt creator, insert custom menu at specified place into menu bar

  - by user363778

  Hi, I have created a menu bar and some menus with Qt creator. One of the menus had to be coded to use QActionGroup features. Now it is easy to add my custom menu to the menu bar with: printMenu = menuBar()-addMenu(tr("&Print")); but my menu will be in the last position of the menu bar. How do I add my menu at a specified place? (e.g. the second place right after the File menu) Greetings

• Portable C++ library for IPC (processes and shared memory), Boost vs ACE vs Poco?

  - by user363778

  Hi, I need a portable C++ library for doing IPC. I used fork() and SysV shared memory until now but this limits me to Linux/Unix. I found out that there are 3 major C++ libraries that offer a portable solution (including Windows and Mac OS X). I really like Boost, and would like to use it but I need processes and it seems like that this is only an experimental branch until now!? I have never heard of ACE or POCO before and thus I am stuck I do not know which one to choose. I need fork(), sleep() (usleep() would be great) and shared memory of course. Performance and documentation are also important criteria. Thanks, for your Help!

• Reading and writing to SysV shared memory without synchronization (use of semaphores, C/C++, Linux)

  - by user363778

  Hi, I use SysV shared memory to let two processes communicate with each other. I do not want the code to become to complex so I wondered if I really had to use semaphores to synchronize the access to the shared memory. In my C/C++ program the parent process reads from the shared memory and the child process writes to the shared memory. I wrote two test applications to see if I could produce some kind of error like a segmentation fault, but I couldn't (Ubuntu 10.04 64bit). Even two processes writing non stop in a while loop to the same shared memory did not produce any error. I hope someone has experience concerning this matter and can tell me if I really must use semaphores to synchronize the access or if I am OK without synchronization. Thanks

  - by user363778

  Hi, I am making a GUI with Qt Creator, Qt 4.6.1 for my c++ application and I cannot find a solution to get radio buttons (or radio button behavior of the menu entries) in my menu bar. I am a newbie to Qt Creator, I hope there is an easy solution for this :-) Greetings
