解决Ubuntu下Sublime Text 2的中文输入问题(使用fc

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:

解决Ubuntu下Sublime Text 2的中文输入问题(使用fcitx输入法)

保存下面这份代码保存为 ~/sublime-imfix.c

typedef GdkSegment GdkRegionBox; 
 
struct _GdkRegion 

  long size; 
  long numRects; 
  GdkRegionBox *rects; 
  GdkRegionBox extents;

  rectangle->width = region->extents.x2 - region->extents.x1; 
  rectangle->height = region->extents.y2 - region->extents.y1; 
  GdkRectangle rect; 
  rect.x = rectangle->x; 
  rect.y = rectangle->y; 
  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 (klass->set_client_window) 
    klass->set_client_window (context, window); 
 
  if(!GDK_IS_WINDOW (window)) 
    return; 
  g_object_set_data(G_OBJECT(context),"window",window); 
  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)
