2：MSYS-1.0.10.exe 安装
3：msysDTK-1.0.1.exe 安装
4：msysCORE-1.0.11-2007.01.19-1.tar.bz2
msysCORE是补丁，所以覆盖在源安装上，下同
5：bash-3.1-MSYS-1.0.11-1.tar.bz2
6：coreutils-5.97-MSYS-1.0.11-snapshot.tar.bz2

7：....还有不少，不过现在没装
8：m4-1.4.7-MSYS.tar.bz2
9：以下是工具：../path/to/configure --prefix=/mingw && make && make install
       autoconf-2.63.tar.bz2.tar

需要设置环境变量

To install 3rd party library and applications which uses the autotools build system the following commands are often used.
./configure --prefix=/mingw
make
make install
13:gtk+-bundle_2.16.0-20090317_win32
add to path gtk+-bundle_2.16.0-20090317_win32\bin
14:glib-2.20.0
./configure --prefix=/mingw
make
make install
gettext error
15:将 gtk+-bundle_2.16.0-20090317_win32得include ,lib copy到E:\MinGW中
其实应该是设置好PKG_CONFIG_PATH，懒省事，就直接copy了
16:gtk+-2.16.0
./configure --prefix=/mingw
make
make install

remove define #ifndef GTK_DISABLE_DEPRECATED

OK，搞定，花费一天时间。编译3小时

DIV+javascript的拖动效果，层拖动，移动效果(兼容)
本篇文章来源于 - http://www.itokit.com - web开发技术 原文地址是：http://www.itokit.com/bbs/viewthread.php?tid=1751&highlight=

其实原理很简单,巧妙使用了css
DIV ,class

1:折叠: class .hide style
通过当前click的event,找到element,设置style为hide,产生效果折叠.
2:drag效果
onload保存全局body,html,初始化container...，对所有class name = module的li onmousedown添加javascript dragstart
dragstart时重载docoment的onmousemove，onmouseup....,将该element Drag.floatIt(e);Drag.drag(e);
floatIt将创建一个新Element，使用style module ghost,将drag element改到这个Element下,新Element,使用style float，然后drop这个ghost element
drop就比较繁琐点了。重新计算位置。因为insertBefore的参数原因，要计算当前elment和colume...。估计是可以优化的

<style type="text/css">
body,table,td,th,input,textarea,button,select{font:13px/16px Verdana,"宋体",sans-serif;}
table{border-collapse:collapse;}
p{margin:0px;}
.container{margin:8px;}
.column{width:33%;margin:0px;padding:0px;float:left;overflow:hidden;}
.module{margin:5px;padding:0px;border:1px solid #dcd;position:relative;background-color:white;list-style:none;}
.title{background-color:#edf;padding:1px 0px;width:100%;overflow:hidden;cursor:move;z-index:0;font-weight:bold;}
.cont{padding:3px;overflow:hidden;}
.hide .cont{display:none;}
.pageTitle{font-weight:bold;text-align:center;}
input.pageTitle{display:none;border:0px;padding:0px;width:100%;}
.webNote{background-color:#ffffe0;border:1px solid #ffffe0;}
textarea.webNote{display:none;overflow:hidden;padding:0px;border:0px;padding:0px;}
.ghost{border:1px dashed red;}
.float{position:absolute;z-index:100;margin:0px;padding:0px;overflow:hidden;list-style:none;-moz-opacity:.75;filter:Alpha(opacity=75);}
</style>

The over operator is, in effect, the normal painting operation (see Painter's algorithm). The in operator is the alpha compositing equivalent of clipping.

As an example, the over operator can be accomplished by applying the following formula to each pixel value:

where C_o is the result of the operation, C_a is the color of the pixel in element A, C_b is the color of the pixel in element B, and α_a and α_b are the alpha of the pixels in elements A and B respectively. If it is assumed that all color values are premultiplied by their alpha values (c_i = α_iC_i), we can rewrite this as:

where

However, this operation may not be appropriate for all applications, since it is not associative ( i.e. it matters whether you first add object A and then object B or first B and then A. For example when building a picture from 3 color-channels it should not take effect in which order you add them, but with this non-associative version it would.). The associative version of this operation is very similar; simply take the newly computed color value and divide it by its new alpha value, as follows:
