[原创开源]emwin自定义控件1--卡片面板

关键字： emwin, 自定义控件，卡片面板

这是一个用emwin写的主页面导航+侧边导航的通用程序框架，emwin仿真环境用的是codeblocks(16或17都可)。

本篇主要介绍了一种卡片式的自定义控件。(由于只是程序框架，所以并不涉及界面美化，我知道丑，所以先说出来~)

- 卡片面板

卡片面板是我自己起的名字，不知道此类控件是否有准确的叫法。

在横屏设备中，卡片面板有着大量的应用，通常用来展示同类信息。

下面的截图来自最近沉迷的手游《QQ飞车》。（飞车一局2分钟左右，比王者玩起来轻松太多了，当然我主要是为看它的GUI设计~）

静态展示

动态展示

- 代码实现

##### 原理就是用emwin系统的皮肤设置函数+按钮私有数据。这相当于一种自定义控件实现的简单方法，通过不同的函数+数据结构就能实现不同功能的控件。

1. 结构体类型

<div>
</div>typedef struct {
int Check;
GUI_COLOR colorPressed;
GUI_COLOR colorUnPress;
GUI_FONT *iconFont;
char iconName[6];
char btnText[10];
int ch;
int sw;
int mode;
float batV;
int batI;
float power;
} BATINFO_USER_SKIN;

复制代码

2. 结构体定义

static BATINFO_USER_SKIN BatInfoData[] = {
{ZL_BTN_CHKMODE_NO, GUI_DARKCYAN, GUI_DARKMAGENTA, &awefont24, "\uf0f6", "stm8", 1, 1, ZL_BATINFO_MODE_CC, 12.305, 2000},
{ZL_BTN_CHKMODE_NO, GUI_DARKCYAN, GUI_DARKMAGENTA, &awefont24, "\uf030", "stm32", 2, 1, ZL_BATINFO_MODE_ST, 10.8, 1500},
{ZL_BTN_CHKMODE_NO, GUI_DARKCYAN, GUI_DARKMAGENTA, &awefont24, "\uf008", "mcu", 3, 0, ZL_BATINFO_MODE_CV},
{ZL_BTN_CHKMODE_NO, GUI_DARKCYAN, GUI_DARKMAGENTA, &awefont24, "\uf226", "linux", 4, 1, ZL_BATINFO_MODE_DC, 12.0, 1800},
{ZL_BTN_CHKMODE_NO, GUI_DARKCYAN, GUI_DARKMAGENTA, &awefont24, "\uf144", "audio", 5},
};

复制代码
