在论坛上获取资源很久了，今天也上传一个我的菜单程序。
此菜单的特点是可以像做网页定义CSS样式一样，定义菜单的显示样式。
包括：菜单项排版，选中不选中文字的颜色，选中不选择按钮图片，图片和文字的排版方式等等。结合美工可以在液晶屏上做出漂亮且功能强大的菜单。
部分代码来自“傻孩子”的菜单实现，在此感谢一下。
以下代码在我的板子上调试通过。
typedef struct IMAGE_RESOURCE
{
uint_16 resource_id;
uint_16 pic_id;
uint_16 xe;
uint_16 ye;
uint_16 xs;
uint_16 ys;
}ImageResource;
//剪切图片资源
const ImageResource ImageResourceList[] =
{
{1, BUTTONPICTURE, 0x67, 0x24, 0xDE, 0x3C}, //按钮图标1，未选择
{2, BUTTONPICTURE, 0x67, 0x43, 0xDE, 0x58}, //按钮图标1，选择
{3, BUTTONPICTURE, 0x67, 0x64, 0xDB, 0x73}, //按钮图标2，未选择
{4, BUTTONPICTURE, 0x67, 0x7E, 0xDB, 0x8D}, //按钮图标2，选择
{0, 0, 0, 0, 0, 0}
};
typedef struct MENUSTYLE
{
uint_8 style;
uint_8 col; //菜单最大列数
uint_8 row; //菜单最大行数
uint_8 dx; //水平间距
uint_8 dy; //垂直间距
uint_8 space_x; //文字跟图片起始地址的差值
uint_8 space_y;
ImageResource* imgid_sel; //被选中时菜单按钮图标句柄,NULL没图片不显示，(需LCD GUI支持图片上文字背景色不显示)
ImageResource* imgid_normal; //不被选中时菜单按钮图标句柄,NULL没图片不显示
uint_32 f_color_sel; //前景色被选择时
uint_32 f_color_normal; //前景色不被选中时
uint_32 b_color_sel; //背景色被选择时
uint_32 b_color_normal; //背景色不被选中时
uint_16 x0; //菜单绘制的起始位置
uint_16 y0;
//......
//还可以定义一些字体类型，文字大小等等

有图有真相，贴上我已经实现的几种样式。
1.单排纯文本样式。
{4, 1, 8, 0, 0x11, 0x14, 0, NULL, NULL, 0x001F, COLOR_WHITE, COLOR_WHITE, 0x001F, 0x70, 0x1A},
2.多排纯文本样式。
{5, 4, 8, 0x40, 0x11, 0x14, 0, NULL, NULL, 0x001F, COLOR_WHITE, COLOR_WHITE, 0x001F, 0x10, 0x30},
3.图文并茂模式，文字在图片上，单排
{1, 1, 5, 0, 0x1F, 8, 5, (ImageResource*)(&ImageResourceList[1]), (ImageResource*)(&ImageResourceList[0]), COLOR_BLACK, COLOR_BLACK, COLOR_WHITE, COLOR_WHITE, 0x64, 0x24},
4.图文并茂模式，文字在图片上，多排
{2, 2, 6, 0x8F, 0x14, 7, 1, (ImageResource*)(&ImageResourceList[3]), (ImageResource*)(&ImageResourceList[2]), COLOR_BLACK, COLOR_BLACK, COLOR_WHITE, COLOR_WHITE, 0x1E, 0x20},
5.图文并茂模式，文字图片分离显示
{3, 1, 10, 0, 0x11, 0x14, 0, (ImageResource*)(&ImageResourceList[5]), (ImageResource*)(&ImageResourceList[4]), 0xFFE0, COLOR_WHITE, COLOR_BLACK, COLOR_BLACK, 0x10, 0x1A},
要做的好看，还是需要美工的配合啊。或者网上找一些按钮图片素材。
