服务器评测
我使用的是Ubuntu 13.10，使用的是fcitx输入法，Google拼音。
昨天安装了Sublime Text 2后，发现切换不出fcitx输入法。遂在网上找了很多方法，最后这种方法很有效，所以分享给大家：
保存下面这份代码保存为 ~/sublime-imfix.c
/*

rect.width = 0;
rect.height = rectangle->height;
//The caret width is 2;
//Maybe sometimes we will make a mistake, but for most of the time, it should be the caret.
if(rectangle->width == 2 && GTK_IS_IM_CONTEXT(local_context)) {
gtk_im_context_set_cursor_location(local_context, rectangle);
}
}
//this is needed, for example, if you input something in file dialog and return back the edit area
//context will lost, so here we set it again.
static GdkFilterReturn event_filter (GdkXEvent *xevent, GdkEvent *event, gpointer im_context)
{
XEvent *xev = (XEvent *)xevent;
if(xev->type == KeyRelease && GTK_IS_IM_CONTEXT(im_context)) {
GdkWindow * win = g_object_get_data(G_OBJECT(im_context),”window”);
if(GDK_IS_WINDOW(win))

int width = gdk_window_get_width(window);
int height = gdk_window_get_height(window);
if(width != 0 && height !=0) {
gtk_im_context_focus_in(context);
local_context = context;
}
gdk_window_add_filter (window, event_filter, context);
安装C/C++的编译环境和gtk libgtk2.0-dev
sudo apt-get install build-essential
sudo apt-get install libgtk2.0-dev
用终端进入 sublime-imfix.c 所在目录，运行下面命令
gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config –libs –cflags gtk+-2.0` -fPIC
用文本编辑器修改 /usr/share/applications/sublime.desktop 文件（这是你安装sublime text 2时自己建的），找到开头为”Exec=”的行（有两行），把subl修改为
bash -c ‘LD_PRELOAD=~/libsublime-imfix.so subl’
OK，在启动器那里点击sublime text 2就可以中文输入了！（注意：在终端输入subl打开时，是不能切换中文输入法的哦）
