为什么正点原子的STM32开发板，液晶触摸屏程序的主程序中，点击屏后只有清屏后，才能重新校准屏

if(key==1)//如虚缓KEY0按下,则执行校准程序

{

Touch_Adjust() //屏幕校准

LCD_Clear(WHITE)//清屏

Save_Adjdata()

Load_Drow_Dialog()

}

改成上面试一渣模下,谢誉毕谢!

1)打开工程目录下的"Exe\GUISimulationDebug.exe"即可看到效果。(2)看完教程000～005就基本会用emWin做项目，其他章节可以需要时再参考。

(1)使用GUIBuilder V5.30创建如下页面并保存为C文件FramewinDLG.c，然后添加到脱机模拟仿真平台CodeBlocks的emwin工程：

(2)用BmpCvt.exe(可在”软件/资料下载”栏目下载)将48×48的图标PNG文件转成C文件并盯歼添加到CodeBlocks工程：

(3)在生成凯闷冲的FramewinDLG.c文件中需要更改罩毕图标的大小为64×64：

(4)在WM_INIT_DIALOG消息中(窗口初始化时程序跑到这里)添加ICONVIEW控件的初始化代码：

......

hItem = WM_GetDialogItem(pMsg->hWin, ID_ICONVIEW_0)

ICONVIEW_SetIconAlign(hItem, ICONVIEW_IA_TOP)

ICONVIEW_SetTextColor(hItem, ICONVIEW_CI_UNSEL, GUI_BLUE)

ICONVIEW_SetTextColor(hItem, ICONVIEW_CI_SEL, GUI_GREEN)

ICONVIEW_SetFrame(hItem, GUI_COORD_X, 0)//设置图标到IconView边框的间距

ICONVIEW_SetFrame(hItem, GUI_COORD_Y, 0)

ICONVIEW_SetSpace(hItem, GUI_COORD_X, (280-64*4)/3)//设置图标和图标之间的间距

ICONVIEW_SetSpace(hItem, GUI_COORD_Y, (140-64*2)/1)

ICONVIEW_SetFont(hItem, GUI_FONT_16_1)

ICONVIEW_AddBitmapItem(hItem, &bm01, "neqee")//添加图标项

ICONVIEW_AddBitmapItem(hItem, &bm02, "SOS")

ICONVIEW_AddBitmapItem(hItem, &bm03, "Phone")

ICONVIEW_AddBitmapItem(hItem, &bm04, "Camera")

ICONVIEW_AddBitmapItem(hItem, &bm05, "Email")

ICONVIEW_AddBitmapItem(hItem, &bm06, "NoteBook")

ICONVIEW_AddBitmapItem(hItem, &bm07, "JTV")

ICONVIEW_AddBitmapItem(hItem, &bm08, "Dollar")

......

(5) WM_NOTIFY_PARENT消息中( *** 作屏幕时程序跑到这里)添加点击提示程序：

switch(ICONVIEW_GetSel(WM_GetDialogItem(pMsg->hWin, ID_ICONVIEW_0)))

{

case 0: TEXT_SetText(WM_GetDialogItem(pMsg->hWin, ID_TEXT_0), "neqee")break

case 1: TEXT_SetText(WM_GetDialogItem(pMsg->hWin, ID_TEXT_0), "SOS")break

case 2: TEXT_SetText(WM_GetDialogItem(pMsg->hWin, ID_TEXT_0), "Phone")break

case 3: TEXT_SetText(WM_GetDialogItem(pMsg->hWin, ID_TEXT_0), "Camera")break

case 4: TEXT_SetText(WM_GetDialogItem(pMsg->hWin, ID_TEXT_0), "Email")break

case 5: TEXT_SetText(WM_GetDialogItem(pMsg->hWin, ID_TEXT_0), "NoteBook")break

case 6: TEXT_SetText(WM_GetDialogItem(pMsg->hWin, ID_TEXT_0), "JTV")break

case 7: TEXT_SetText(WM_GetDialogItem(pMsg->hWin, ID_TEXT_0), "Dollar")break

//case 8: TEXT_SetText(WM_GetDialogItem(pMsg->hWin, ID_TEXT_0), "Jobbet")break

}

(6)编译运行：
