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~)

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
- 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
3. 卡片面板实现代码
- // 卡片面板控件 ok
- int button_drawskin_batinfo(const WIDGET_ITEM_DRAW_INFO* pItem)
- {
- BATINFO_USER_SKIN *pUsr;
- GUI_RECT rect;
- char acBuf[20];
- int xSize;
- int ySize;
- int strXsizeLen;
- int xPos;
- switch (pItem->Cmd)
- {
- case WIDGET_ITEM_DRAW_TEXT:
- BUTTON_GetText(pItem->hWin, acBuf, sizeof(acBuf));
- rect.x0 = pItem->x0;
- rect.x1 = pItem->x1;
- rect.y0 = pItem->y0;
- rect.y1 = pItem->y1;
- GUI_SetFont(BUTTON_GetFont(pItem->hWin));
- GUI_SetTextMode(GUI_TM_TRANS);
- GUI_SetColor(GUI_LIGHTGREEN);
- rect.y0 = rect.y1 / 12;
- BUTTON_GetUserData(pItem->hWin, &pUsr, sizeof(pUsr));
- GUI_DispStringAt("CH", 3, rect.y0);
- GUI_DispDecAt(pUsr->ch, 15 + 8, rect.y0, 2);
- if (pUsr->sw == 1) {
- strXsizeLen = GUI_GetStringDistX("ON");
- GUI_SetColor(GUI_WHITE);
- GUI_AA_FillRoundedRect(63-2, rect.y0-2, 63+strXsizeLen+2, rect.y0+16, 2);
- GUI_SetColor(GUI_RED);
- GUI_DispStringAt("ON", 63, rect.y0);
- //

- }
