  • Objective-C++ Memory Problem

    - by Stephen Furlani
    Hello, I'm having memory woes. I've got a C++ Library (Equalizer from Eyescale) and they use the Traversal Visitor Pattern to allow you to add new functionality to their classes. I've finally figured out how it works, and I've got a Visitor that just returns the properties from one of the objects. (since I don't know how they're allocated). so. My little code does this: VisitorResult AGLContextVisitor::visit( Channel* channel ) { // Search through Nodes, Pipes until we get to the right window. // Add some code to make sure we find the right one? // Not executing the following code as C++ in gdb? eq::Window* w = channel->getWindow(); OSWindow* osw = w->getOSWindow(); AGLWindow* aw = (AGLWindow *)osw; AGLContext agl_ctx = aw->getAGLContext(); this->setContext(agl_ctx); return TRAVERSE_PRUNE; } So here's the problem. eq::Window* w = channel->getWindow(); (gdb) print w 0x0 BUT If I do this: (gdb) set objc-non-blocking-mode off (gdb) print w=channel->getWindow() 0x300effb9 // an honest memory location, and sets w as verified in the Debugger window of XCode. It does the same thing for osw. I don't get it. Why would something work in (gdb) but not in the code? The file is completely a cpp file, but it seems to be running in objc++, since I need to turn blocking off. Help!? I feel like I'm missing some memory-management basic thing here, either with C++ or Obj-C. [edit] channel-getWindow() is supposed to do this: /** @return the parent window. @version 1.0 */ Window* getWindow() { return _window; } The code also executes fine if I run it from a C++-only application. [edit] No... I tried creating a simple stand-alone program since I was tired of running it as a plugin. Messy to debug. And no, it doesn't run in the C++ program either. So I'm really at a loss as to what I'm doing wrong. Thanks, -- Stephen Furlani

    - by Tor
    In R I'm looking to suppress the output of one command (in this case, the apply function). Is it possible to do this without using sink()?

  • find command in Linux

    - by Martin
    My goal is to find all pdf files on a remote machine, so I resort to the useless command find. So I type find . *.pdf or find ~ .pdf or find ~ ".pdf" and I get nothing. I do the same on my machine and I get nothing. I do a regular search from the menu on my machine and I find quite a few pdf files. Would somebody please tell me what am I doing wrong?

  • vim is not obeying command aliases

    - by Nadal
    I use bash on mac and one of the aliases is like this alias gitlog='git --no-pager log -n 20 --pretty=format:%h%x09%an%x09%ad%x09%s --date=short --no-merges' However when I do :! gitlog I get /bin/bash: gitlog: command not found I know I can add aliases like this in my .gitconfig [alias] co = checkout st = status ci = commit br = branch df = diff However I don't want to add all my bash aliases to .gitconfig. That is not DRY. Is there a better solution?

  • Swing on OSX: How to Trap command-Q?

    - by yar
    After being convinced ("schooled") that Swing apps on Mac do look native, I'm trying to make mine look as native as possible. Everything looks great, but when I hit command-Q or do it from the menu, my windowStateChanged(WindowEvent e) is not firing on my main JFrame (if I exit in any other way, it does fire). How can I respond to the real Apple quit?

  • create menus in command line

    - by Miles Rout
    How can one create menus in the command line program? I've tried stuff like: cin input; switch (input) { case (1): // do stuff case (2): // ... } but then I've had the problem of sub-menus, and going back to the same menu, etc. The first program I wrote (apart from exercises) that tried to use the switch idea for the menus had goto statements because the alternative was heaps of (at the time) complicated loops.
