C / sfMouse_getPosition with sfRenderWindow*?

« on: May 01, 2012, 12:46:09 pm »

I have an sfRenderWindow*, but sfMouse_getPosition() wants an sfWindow*. I couldn't find any method to make/get an sfWindow* from an sfRenderWindow* without modifying the source. Is there an orthodox (and fast) method, or should I just hack CSFML?

Audio / write an audio file in small chunks

« on: October 17, 2010, 03:11:38 am »

Is it possible to write audio file in small chunks? For example, if I want to record an audio stream into a file. But when I just want to write in an existing file, it seems SFML overwrites it. Thanks in advance

SFML projects / audoid - audio synthesis API / application

« on: October 15, 2010, 06:19:54 am »

I started an audio synthesis project, called audoid. It will be a general soundsynth API, and later on, I will add a GUI on the top of it. It is very ugly at the moment (I mean the code quality), but over time it will be better and better (hopefully .

Code: http://code.google.com/p/audoid/

Oh, and uses SFML2. Code::Blocks projectfile included.

Audio / [SOLVED] (1.5) weird problem with debugging

« on: March 25, 2010, 01:36:03 pm »

(Sorry for my english, it isn't my native language.)

I am creating a... well, kind of sound editing - music creation program. I only recently started to use sf::SoundStream. Until that point, I had no problem. I used debugger, I was happy. Now, it is over. When there is sf::SoundStream in my code (one of my class inherits from it, as in the tutorial), and i want to debug it, the debugger starts, but nothing happens. I don't know, whether the program starts or not, but it doesn't even step into main().

Everything is ok - I use the debug versions of libraries, use the debug build (I use Code::Blocks, btw), and use debugging mode. The debugger output says:

Starting debugger:
done
Registered new type: wxString
Registered new type: STL String
Registered new type: STL Vector
Setting breakpoints
Debugger name and version: GNU gdb (GDB) 7.0.50.20100212
Child process PID: 2312
* 1 Thread 2312.0x670  __static_initialization_and_destruction_0 (__initialize_p=1, __priority=65535) at D:/Programmes/CodeBlocks/bin/../lib/gcc/mingw32/3.4.4/../../../../include/c++/3.4.4/iostream:77

after several "step" commands:

(... lot of I-can't-understand things ...)

In KERNEL32!IsBadCodePtr () (C:\WINDOWS\system32\kernel32.dll)
Single stepping until exit from function KERNEL32!IsBadCodePtr,
which has no line number information.
0x7c80a1c3 in WideCharToMultiByte () from C:\WINDOWS\system32\kernel32.dll
In WideCharToMultiByte () (C:\WINDOWS\system32\kernel32.dll)

In WideCharToMultiByte () (C:\WINDOWS\system32\kernel32.dll)
Single stepping until exit from function WideCharToMultiByte,
which has no line number information.

and this three steps seem to iterate forever (didn't have much patience).

All I have throughout this is an empty console window, nothing else. (And the IDE, of course ) I'm using MinGW-TDM, but i downloaded gdb-7.0.50.

My question is: what is causing this, and what can I do?

If this is not enough, I will create a minimal environment to reproduce this, on request. Thanks for any help
(No, please don't say not to use debugger... I'm too lazy and comfortable )

And thanks Laurent, for making this great library. It is really fun to use it ^_^
