silk-GUI图形界面开发一个词典

了解使用的库

Silk内置了一些GUI类库供使用者开发MacOS上的图形界面程序，只需引用gui.si即可

准备

首先要知道app需要什么功能，这里我要的是查询单词，可以听语音，还可以存储生词！

那么就要这两个库："gui.si"和"sqlite.si"

GUI负责界面设计，sqlite负责生词存储（当然你也可以改为CMySql，链接服务器数据库）

上代码

#include "gui.si"
#include "sqlite.si"

_word=null;
_textview=null;
_checkbox=null;

ok，接下来看看效果：

解释：

这里用了一个bing词典以及韩小韩的文字转语音的api，这个api有个bug，不能空格，我还在研究这个语言的转译，等我回了再补充，如果你会可以发个评论告诉我！

其实你只要看个官方文档就大差不差了:https://silklang.org/chinese/tutorial_db.html
