大家好,我用IMAGE控件做按钮利用IMAGE触摸事件处理任务目前遇到困难, #include "home.h" #define ID_SET_TOUCH (ID_SET_BASE + 1) #define ID_SET_tiME (ID_SET_BASE + 2) #define ID_SET_BKIMAGE (ID_SET_BASE + 3) #define ID_SET_HELP (ID_SET_BASE + 4) #define ID_SET_EXIT (ID_SET_BASE + 5) IMAGE_Handle SET_hImage[5]; static void _cbDialog(WM_MESSAGE * pMsg) { static bool app=false; int i; FIL bmp; switch(pMsg ->MsgId) { case WM_PAINT: //重绘 if(app==false) { f_open(&bmp,"picture/home/1.bmp",FA_READ); GUI_BMP_DrawEx(_Get_BackImage,(void *)&bmp,0,20); //这里重绘的是背景图片,可以正常显示背景 f_close(&bmp);
f_open(&bmp,"picture/set/touch/touch.bmp",FA_READ); IMAGE_SetBMPEx(SET_hImage[0],_Get_BackImage,(void *)&bmp); //这里重绘第一个IMAGE图标,不能显示 f_close(&bmp);
f_open(&bmp,"picture/set/time/time.bmp",FA_READ); IMAGE_SetBMPEx(SET_hImage[1],_Get_BackImage,(void *)&bmp); //第二个图标也不能显示 f_close(&bmp);
f_open(&bmp,"picture/set/bkimage/bkimage.bmp",FA_READ); IMAGE_SetBMPEx(SET_hImage[2],_Get_BackImage,(void *)&bmp); //以下都不能显示 f_close(&bmp);
f_open(&bmp,"picture/set/help/help.bmp",FA_READ); IMAGE_SetBMPEx(SET_hImage[3],_Get_BackImage,(void *)&bmp); f_close(&bmp);
f_open(&bmp,"picture/set/exit/exit.bmp",FA_READ); IMAGE_SetBMPEx(SET_hImage[4],_Get_BackImage,(void *)&bmp); f_close(&bmp); } break;
case WM_NOTIFY_PARENT: switch(WM_GetId(pMsg ->hWinSrc)) { case ID_SET_TOUCH: //触摸校准 switch(pMsg ->Data.v) { case WM_NOTIFICATION_CLICKED: f_open(&bmp,"picture/set/touch/_touch.bmp",FA_READ); IMAGE_SetBMPEx(SET_hImage[0],_Get_BackImage,(void *)&bmp); f_close(&bmp); break;
case WM_NOTIFICATION_RELEASED: app =true; for(i=0;i<5;i++) WM_DeleteWindow(SET_hImage);
IS_Touch(true); Create_SetDesktop(); app =false; break; } break;
case ID_SET_TIME: //时间设置 switch(pMsg ->Data.v) { case WM_NOTIFICATION_CLICKED: f_open(&bmp,"picture/set/time/_time.bmp",FA_READ); IMAGE_SetBMPEx(SET_hImage[1],_Get_BackImage,(void *)&bmp); f_close(&bmp); break;

case ID_SET_BKIMAGE: //背景图片 switch(pMsg ->Data.v) { case WM_NOTIFICATION_CLICKED: f_open(&bmp,"picture/set/bkimage/_bkimage.bmp",FA_READ); IMAGE_SetBMPEx(SET_hImage[2],_Get_BackImage,(void *)&bmp); f_close(&bmp); break;
case WM_NOTIFICATION_RELEASED: f_open(&bmp,"picture/set/bkimage/bkimage.bmp",FA_READ); IMAGE_SetBMPEx(SET_hImage[2],_Get_BackImage,(void *)&bmp); f_close(&bmp); break; } break;
case ID_SET_HELP: //帮助 switch(pMsg ->Data.v) { case WM_NOTIFICATION_CLICKED: f_open(&bmp,"picture/set/help/_help.bmp",FA_READ); IMAGE_SetBMPEx(SET_hImage[3],_Get_BackImage,(void *)&bmp); f_close(&bmp); break;

case ID_SET_EXIT: //返回 switch(pMsg ->Data.v) { case WM_NOTIFICATION_CLICKED: f_open(&bmp,"picture/set/exit/_exit.bmp",FA_READ); IMAGE_SetBMPEx(SET_hImage[4],_Get_BackImage,(void *)&bmp); f_close(&bmp); break;
case WM_NOTIFICATION_RELEASED: app =false; for(i=0;i<5;i++) WM_DeleteWindow(SET_hImage); Create_HomeDesktop(); break; } break; } break;
default: WM_DefaultProc(pMsg); break; } } void Create_SetDesktop() //这里是创建5个IMAGE控件,然后在消息中设置IMAGE的bmp图片 { WM_SetCallback(WM_HBKWIN,_cbDialog); SET_hImage[0]= IMAGE_CreateEx(0, 20,240,30,WM_HBKWIN,WM_CF_SHOW,IMAGE_CF_TILE,ID_SET_TOUCH); SET_hImage[1]= IMAGE_CreateEx(0, 50,240,30,WM_HBKWIN,WM_CF_SHOW,IMAGE_CF_TILE,ID_SET_TIME); SET_hImage[2]= IMAGE_CreateEx(0, 80,240,30,WM_HBKWIN,WM_CF_SHOW,IMAGE_CF_TILE,ID_SET_BKIMAGE); SET_hImage[3]= IMAGE_CreateEx(0,110,240,30,WM_HBKWIN,WM_CF_SHOW,IMAGE_CF_TILE,ID_SET_HELP); SET_hImage[4]= IMAGE_CreateEx(0,140,240,30,WM_HBKWIN,WM_CF_SHOW,IMAGE_CF_TILE,ID_SET_EXIT); }
现在程序的状态是开机显示主界面,主界面有很多图标其中的设置图标被点击后调用Create_SetDesktop()切换到设置界面,设置界面就会创建以上5个IMAGE图标(用来做按钮),但是切换后只显示背景图片,IMAGE的BMP图标都没有显示出来,我在相应位置触摸是可以正常进入下一级菜单(本级菜单分别是触摸校验/时间设置/背景图片设置/帮助/返回),比如在触摸校验的位置触摸就可以正常进入触摸校验程序、触摸返回的位置就正常返回到了主界面,从这点可以说明IMAGE控件是正常被创建了,而且消息可以正常处理就是加载的图标不显示,请大家帮我看看是为什么?是不是IMAGE的控件少了哪些设置?我调试了IMAGE控件创建正常返回了句柄,f_open也正常读到了数据,就是 IMAGE_SetBMPEx()函数不能显示,如果我把IMAGE_SetBMPEx()全部换成GUI_BMP_DrawEx()就可以正常显示所有图标,但是这么做程序编写就不规范了。
