  • event handling in C++

    - by Max
    Hi. I'm writing a game in C++, and I'm trying to get it to recognize keyboard and mouse events. Google tells me that boost.signal is suitable for event handling, but none of the code samples or tutorials I've found tell me how to associate a keypress or mouseclick with a function. Can anyone shed any light on this?

  • Quaternion Cameras and projectile vectors

    - by Tom J Nowell
    In our software we have a camera based on mouse movement, and a quarternion at its heart. We want to fire projectiles from this position, which we can do, however we want to use the camera to aim. The projectile takes a vector which it will add to its position each game frame. How do we acquire such a vector from a given camera/quaternion?

  • TextMate can show definition of a function easily?

    - by Jian Lin
    I am using TextMate on a Ruby on Rails project and wonder if you can put the mouse on link_to, and then press a key and it will show the definition of link_to, or does this for any other helper functions? Or, click open a box and type in a function name and it will show you the definition?

  • In gzip libary, what's the difference between 'uncompress' and 'gzopen' ?

    - by Sol
    There are some functions to decompress in zlib library(zlib version 1.2.3) I want to decompress my source zip(.gz) file using 'uncompress' function. It is now working(error code -3) but gzopen is. It is still not working when I input payload pointer(passing gzip header) to 'uncompress' . So the question is "What's the valid arguments for uncompress function?" and If it needs different format, how can I make it? Google doesn't helpful this time :(

  • What is the point of function pointers?

    - by gramm
    Hi, I have trouble seing the utility of the function pointers. I guess it may be useful in some cases (they exist, after all), but I can't think of a case where it's better or unavoidable to use a function pointer. Could you give some example of good use of function pointers (in C or C++)? Many thanks :)

  • 'Invalid conversion from some_type** to const some_type**'

    - by petersohn
    I've got a function that requires const some_type** as an argument (some_type is a struct, and the function needs a pointer to an array of this type). I declared a local variable of type some_type*, and initialized it. Then I call the function as f(&some_array), and the compiler (gcc) says: error: invalid conversion from ‘some_type**’ to ‘const some_type**’ What's the problem here? Why can't I convert a variable to const?

  • STL map - insert or update

    - by CodeJunkie
    I have a map of objects and I want to update the object mapped to a key, or create a new object and insert into the map. The update is done by a different function that takes a pointer to the object (void update(MyClass *obj)) What is the best way to "insert or update" an element in a map?

  • Problem getting size of Website Xcode

    - by Michael Amici
    When i try and compile I come up with a warning that reads initialization makes pointer from integer without a cast. No clue why. I am just trying to get the size of a website. #import "Lockerz_RedemptionViewController.h" @implementation Lockerz_RedemptionViewController -(IBAction)startLoop:(id) sender { NSData *dataNew = [NSData dataWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://www.google.com/"]]]; NSUInteger *len = [dataNew length]; //error is here NSLog(@"%@", len); }

  • How do you return a string from a function correctly in Dynamic C?

    - by aquanar
    I have a program I am trying to debug, but Dynamic C apparently treats strings differently than normal C does (well, character arrays, anyway). I have a function that I made to make an 8 character long (well, 10 to include the \0 ) string of 0s and 1s to show me the contents of an 8-bit char variable. (IE, I give it the number 13, it returns the string "0001101\0" ) When I use the code below, it prints out !{happy face] 6 times (well, the second one is the happy face alone for some reason), each return comes back as 0xDEAE or "!\x02. I thought it would dereference it and return the appropriate string, but it appears to just be sending the pointer and attempting to parse it. This may seem silly, but my experience was actually in C++ and Java, so going back to C brings up a few issues that were dealt with in later programming languages that I'm not entirely sure how to deal with (like the lack of string variables). How could I fix this code, or how would be a better way to do what I am trying to do (I thought maybe sending in a pointer to a character array and working on it from the function might work, but I thought I should ask to see if maybe I'm just trying to reinvent the wheel). Currently I have it set up like this: this is an excerpt from the main() display[0] = '\0'; for(i=0;i<6;i++) { sprintf(s, "%s ", *char_to_bits(buffer[i])); strcat(display, s); } DispStr(8,5, display); and this is the offending function: char *char_to_bits(char x) { char bits[16]; strcpy(bits,"00000000\0"); if (x & 0x01) bits[7]='1'; if (x & 0x02) bits[6]='1'; if (x & 0x04) bits[5]='1'; if (x & 0x08) bits[4]='1'; if (x & 0x10) bits[3]='1'; if (x & 0x20) bits[2]='1'; if (x & 0x40) bits[1]='1'; if (x & 0x80) bits[0]='1'; return bits; } and just for the sake of completion, the other function is used to output to the stdio window at a specific location: void DispStr(int x, int y, char *s) { x += 0x20; y += 0x20; printf ("\x1B=%c%c%s", x, y, s); }

  • Monitor vs Watch on SourceForge Tracker

    - by Vulcan Eager
    What exactly is the difference Watching and Monitoring a project on the SourceForge Tracker UI? PS: The tool tips are really helpful. Hold your mouse over the "Monitor" button and it says "Monitor this project"... hold it over "Watch" and it says nothing. That's really awesome coming from SF.

  • Change background color when clicked textbox in C#

    - by jweinraub
    I like for the textbox to change the background when the textbox has focus (if clicked with a mouse, tabbed into, etc). I don't like the textchange method since it won't change until one character has been added. private void txtFoo_OnGotFocus(object sender, EventArgs e) { txtFoo.BackColor = Color.LightYellow; txtBar.BackColor = Color.White; } This doesn't seem to work for me. What am I doing wrong?

  • Use .net reactive in silverlight to generate multiple events.

    - by Mrt
    I have a method in a silverlight application. I want to start calling this method when an event occurs (mouse move), and continue to call this method every 1 second until a simple boolean condition changes. Is this possible ? I can't work out how to get the rx to generate multiple 'events' from the single event

  • Determining the word width in C

    - by das_weezul
    Hi! I'm learning C right now and so I'm fiddling about with pointers. Is there a way to determine the word width of the CPU in C because I'm writing a small program which prints it's own stack (Because I'm curious how it is structured), so that information would come in handy. Right now I'm using an int pointer, as an integer is 4 Bytes wide and I'm using a 32-bit Intel Atom CPU. Thanks in advance, C gurus ;o)

  • Login screen delay in CentOS 5.4 x64

    - by user208728
    I was happily running my CentOS 5.4 before something bad happened that somehow corrupted the 'nautilus' package. It stopped me from using the default Gnome Desktop. Then I installed (using yum) the KDE and nautilus later on. Now, KDE is running perfectly with one exception that it takes around 10 minutes before showing up the Login Screen and only a blue screen with mouse pointer keeps showing during those 10 minutes. Thanks in Anticipation. Regards, Talal

  • LInux C++: how do profile time wasted due to cache misses?

    - by anon
    I know that I can use gprof to benchmark my code. However, I have this problem -- I have a smart pointer that has an extra level of indirection (think of it as a proxy object). As a result, I have this extra layer that effects pretty much all functions, and screws with caching. Is there a way to measure the time my CPU wastes due to cache misses? Thanks!

  • How can I lock the cursor to the inside of a window on Mac OS X?

    - by ZorbaTHut
    I'm trying to put together a game for Mac OS X which involves a lot of fast action and flinging around of the mouse cursor. If the user wants to play in windowed mode, I'd quite like to lock the cursor to the inside of the window to avoid accidentally changing programs in the heat of battle (obviously this will cancel itself if the user changes programs or hits escape for the pause menu.) On Windows, this can be accomplished easily with ClipCursor(). I can't find an equivalent on Mac OS X. Is there one?

  • Adobe AIR canvas dimensions messed up

    - by Nikhil
    I'm messing about with Canvas in Adobe Air. But their seems to be some issue with the mouse coordinates. The more I click towards the right, the difference between the draw position and actual click increases. My code is Wb.canvas.fillRect(evt.clientX-canvasTag.clientX, evt.clientY-canvasTag.clientY, 50, 50);
