Fixed bug #113: Date: Sat, 16 Apr 2005 08:39:22 +1000 From: "Eric Mangold" Subject: [SDL] Window manager does not show SDL window titles Hello, I have an issue with SDL-using applications and the sawfish window manager. The problem is that SDL windows do not show the window caption. My gnome panel *does* show the window name, but the actual sawfish window frame shows no caption at all. All other non-SDL applications that I use work fine. I tried a couple other window managers, and they *were* able to show the SDL window captions correctly. Though there many be other WMs that can't. I believe the problem is that SDL is using the UTF8_STRING type for the window's WM_NAME and WM_ICON properties. In fact, WM_NAME and WM_ICON are supposed to set to a TEXT type, usually STRING (ISO 8859-1). The property names _NET_WM_NAME and _NET_WM_ICON_NAME should be used to store the UTF8_STRING versions of the window title and icon name. You can see the properties I refer to with a command like this: xprop|grep -e "WM.*NAME" Please note the freedesktop.org standard: http://standards.freedesktop.org/wm-spec/wm-spec-1.3.html#id2506954 This page talks a little bit about the history of these properties. Just search down the page for "WM_NAME". http://www.cl.cam.ac.uk/~mgk25/unicode.html Please let me know if I can be of any assistance in resolving this issue. Thanks, Eric Mangold

.SH "NAME"
SDL_MixAudio\- Mix audio data
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBvoid \fBSDL_MixAudio\fP\fR(\fBUint8 *dst, Uint8 *src, Uint32 len, int volume\fR);
.SH "DESCRIPTION"
.PP
This function takes two audio buffers of \fBlen\fR bytes each of the playing audio format and mixes them, performing addition, volume adjustment, and overflow clipping\&. The \fBvolume\fR ranges from 0 to \fBSDL_MIX_MAXVOLUME\fP and should be set to the maximum value for full audio volume\&. Note this does not change hardware volume\&. This is provided for convenience -- you can mix your own audio data\&.
.PP
.RS
\fBNote:  
.PP
Do not use this function for mixing together more than two streams of sample data\&. The output from repeated application of this function may be distorted by clipping, because there is no accumulator with greater range than the input (not to mention this being an inefficient way of doing it)\&. Use mixing functions from SDL_mixer, OpenAL, or write your own mixer instead\&.
