STM32f429+ FreeRTOS +EMWIN + 5寸屏 使用GUI_WIDGET_CREATE_INFO 资源表创建窗体， 1）主窗体使用： hWinMain = GUI_CreateDialogBox(_aDialogCreate, GUI_COUNTOF(_aDialogCreate), _cbDialog_main, WM_HBKWIN, 0, 0); 2）外部实体按键检测到对应的键值，发送自定义消息，WM_SendMessageNoPara(WM_GetClientWindow(hWinMain), MSG_DCV); 3）自定义消息处理--》_cbDialog_main 回调函数 -- case MSG_DCV: hDCV = GUI_CreateDialogBox(_aDialogCreate_DCV, GUI_COUNTOF(_aDialogCreate_DCV), &_cbCallback_DCV_new, WM_HBKWIN, 0, 0); 4）创建窗体显示控件 但是下个几个情况： ① 在 case WM_INIT_DIALOG中对EDIT 进行WM_SetFocus操作时，窗体不能正确显示；单独在MainTask函数调用是正常的； 假若在MainTask.c 文件使用hWinMain = GUI_CreateDialogBox(_aDialogCreate_DCV, GUI_COUNTOF(_aDialogCreate_DCV), &_cbCallback_DCV_new, 0, 0, 0); 直接创建，窗体可以正常显示，也能聚焦到EDIT0, ② 在 case WM_INIT_DIALOG中对BUTTON 进行BUTTON_SetFocusable(hutem，0)操作时，窗体不能正确显示； ③ case MSG_Set_Limit: 外部实体按键发送自定义消息，收到后对EDIT0设置焦点，Focus_index的值仿真也变成01，下面的EDIT_SetSel(hItem,0,-1); 本意是对EDIT0 的内容全选， 实际的测试结果不正常 单片机死机 ； ============================================================================= ① 的问题，仿真运行程序发现，程序运行卡死在 _cbCallback_DCV_new回调函数中的WM_INIT_DIALOG部分的 hItem = WM_GetDialogItem(pMsg->hWin, ID_EDIT_2); 这个位置；如若将这部分代码注释掉，则卡死在后面的代码语句； ============================================================================= // 窗体资源表 static const GUI_WIDGET_CREATE_INFO _aDialogCreate_DCV[] = { { WINDOW_CreateIndirect, "Window", ID_WINDOW_0, 0, 0, 800, 480, 0, 0x0, 0 }, { BUTTON_CreateIndirect, "Button", ID_BUTTON_0, 660, 20, 120, 40, 0, 0x0, 0 }, { BUTTON_CreateIndirect, "Button", ID_BUTTON_1, 660, 80, 120, 40, 0, 0x0, 0 }, { BUTTON_CreateIndirect, "Button", ID_BUTTON_2, 660, 140, 120, 40, 0, 0x0, 0 }, { BUTTON_CreateIndirect, "Button", ID_BUTTON_3, 660, 200, 120, 40, 0, 0x0, 0 }, { BUTTON_CreateIndirect, "Button", ID_BUTTON_4, 660, 260, 120, 40, 0, 0x0, 0 }, { BUTTON_CreateIndirect, "Button", ID_BUTTON_5, 660, 320, 120, 40, 0, 0x0, 0 }, { BUTTON_CreateIndirect, "Button", ID_BUTTON_6, 660, 380, 120, 40, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_0, 260, 10, 90, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_1, 450, 107, 55, 38, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_2, 530, 88, 80, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_3, 530, 120, 80, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_4, 90, 200, 40, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_8, 40, 91, 420, 64, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_9, 280, 200, 80, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_11, 20, 340, 80, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_12, 90, 340, 120, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_13, 190, 340, 80, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_14, 20, 385, 140, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_15, 130, 385, 120, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_16, 250, 385, 120, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_17, 360, 384, 120, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_21, 470, 340, 121, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_23, 470, 385, 90, 32, 0, 0x0, 0 }, { TEXT_CreateIndirect, "Text", ID_TEXT_24, 571, 385, 80, 32, 0, 0x0, 0 }, { EDIT_CreateIndirect, "Edit", ID_EDIT_0, 90, 335, 100, 37, 0, 0x0, 0 }, { EDIT_CreateIndirect, "Edit", ID_EDIT_1, 580, 335, 60, 37, 0, 0x0, 0 }, { EDIT_CreateIndirect, "Edit", ID_EDIT_2, 128, 200, 150, 37, 0, 0x0, 0 }, { EDIT_CreateIndirect, "Edit", ID_EDIT_0, 90, 335, 100, 37, 0, 0x0, 0 }, { EDIT_CreateIndirect, "Edit", ID_EDIT_1, 580, 335, 60, 37, 0, 0x0, 0 }, { EDIT_CreateIndirect, "Edit", ID_EDIT_2, 128, 200, 150, 37, 0, 0x0, 0 }, };
