    • Window <-> child dialog data exchange

      Hi,

      I have a window with several Edit boxes, when i click the edit i open a dialog where i change a global array value.
      The window and the dialog are defined in 2 different c files as i intend to use this dialog in several windows.
      The dialog is created as follows:

      Source Code

      1. #define ID_VALUE_CHANGE 1000#define ID_SMALL_CHANGE 1001#define ID_BIG_CHANGE 1002#define ID_BUTTON_OK 1003#define ID_BUTTON_KO 1004
      2. static const GUI_WIDGET_CREATE_INFO _aDialogCreate[] = { { FRAMEWIN_CreateIndirect, "Value Editor", ID_VALUE_CHANGE, 127, 68, 225, 135, 0, 0x0, 0 }, { SPINBOX_CreateIndirect, NULL, ID_SMALL_CHANGE, 3, 3, 150, 70, 0, 0x0, 0 }, { SLIDER_CreateIndirect, NULL, ID_BIG_CHANGE, 3, 85, 150, 24, 0, 0x0, 0 }, { BUTTON_CreateIndirect, NULL, ID_BUTTON_OK, 165, 3, 50, 50, 0, 0x0, 0 }, { BUTTON_CreateIndirect, NULL, ID_BUTTON_KO, 165, 63, 50, 50, 0, 0x0, 0 },};
      3. static void _cbDialog(WM_MESSAGE * pMsg) { int NCode; int Id;//make these as static for ImageControl.c to avoid repeated calls of WM_GetDialogItem BUTTON_Handle hButton; SPINBOX_Handle hSpin; SLIDER_Handle hSlide; switch (pMsg->MsgId) { case WM_INIT_DIALOG: hButton = WM_GetDialogItem(pMsg->hWin, ID_BUTTON_OK); BUTTON_SetBitmapEx(hButton, BUTTON_BI_UNPRESSED, &bmLoad, 13, 13); hButton = WM_GetDialogItem(pMsg->hWin, ID_BUTTON_KO); BUTTON_SetBitmapEx(hButton, BUTTON_BI_UNPRESSED, &bmOff, 13, 13); hSpin = WM_GetDialogItem(pMsg->hWin, ID_SMALL_CHANGE); SPINBOX_SetFont(hSpin, GUI_FONT_32B_1); SPINBOX_SetRange(hSpin, 0, maxProfile[myItemIndex]); SPINBOX_SetValue(hSpin, arrProfile[myItemIndex]); hSlide = WM_GetDialogItem(pMsg->hWin, ID_BIG_CHANGE); SLIDER_SetRange(hSlide, 0, maxProfile[myItemIndex]); SLIDER_SetValue(hSlide, arrProfile[myItemIndex]); break; case WM_NOTIFY_PARENT: Id = WM_GetId(pMsg->hWinSrc); NCode = pMsg->Data.v; switch(Id) { case ID_BIG_CHANGE: // Notifications sent by 'Slider' case ID_SMALL_CHANGE: // Notifications sent by 'Spinbox' if(NCode == WM_NOTIFICATION_VALUE_CHANGED) { hSpin = WM_GetDialogItem(pMsg->hWin, ID_SMALL_CHANGE); hSlide = WM_GetDialogItem(pMsg->hWin, ID_BIG_CHANGE); if(Id == ID_BIG_CHANGE) { SPINBOX_SetValue(hSpin, SLIDER_GetValue(hSlide)); } else { SLIDER_SetValue(hSlide, SPINBOX_GetValue(hSpin)); } } break; case ID_BUTTON_OK: // Notifications sent by 'Button' if(NCode == WM_NOTIFICATION_RELEASED) { WM_GetClientWindow(); hSpin = WM_GetDialogItem(pMsg->hWin, ID_SMALL_CHANGE); arrProfile[myItemIndex] = SPINBOX_GetValue(hSpin); WM_DeleteWindow(pMsg->hWin); } break; case ID_BUTTON_KO: // Notifications sent by 'Button' if(NCode == WM_NOTIFICATION_RELEASED) WM_DeleteWindow(pMsg->hWin); break; } break; default: WM_DefaultProc(pMsg); break; }}
      4. WM_HWIN ShowEditValue(WM_HWIN myItem, U8 myIdx) { parentItem = myItem; myItemIndex = myIdx; //return the handle of the dialog return GUI_CreateDialogBox(_aDialogCreate, GUI_COUNTOF(_aDialogCreate), _cbDialog, myItem, 0, 0);};



      the parent window

      Source Code

      1. static WM_HWIN _hManual;
      2. static const GUI_WIDGET_CREATE_INFO _aDialogCreate[] = { { WINDOW_CreateIndirect, NULL, ID_ManualMenu, -1, 0, 480, 272, 0, 0x0, 0 }, { EDIT_CreateIndirect, NULL, ID_Sequence_Delay, 102, 50, 90, BtnSize, 0, 0x0, 0 }, { BUTTON_CreateIndirect, "Shutter 2", ID_Shutter2, 270, 150, 140, BtnSize, 0, 0x0, 0 }, { BUTTON_CreateIndirect, NULL, ID_ScreenOff, 10, 230, BtnSize, BtnSize, 0, 0x0, 0 },};
      3. static void _cbDialog(WM_MESSAGE * pMsg) { WM_HWIN hItem; WM_HWIN hEditWin; U8 crtItem; arrProfile[Sequence_Delay] = 999; int NCode; int Id; switch (pMsg->MsgId) { case WM_INIT_DIALOG: hItem = WM_GetDialogItem(pMsg->hWin, ID_Sequence_Delay); EDIT_SetFont(hItem, GUI_FONT_32B_1); EDIT_SetDecMode(hItem, arrProfile[Sequence_Delay], 0, maxProfile[Sequence_Delay], 0, GUI_EDIT_NORMAL); hItem = WM_GetDialogItem(pMsg->hWin, ID_Exit); BUTTON_SetBitmapEx(hItem, BUTTON_BI_UNPRESSED, &bmOff, 4, 4); hItem = WM_GetDialogItem(pMsg->hWin, ID_ScreenOff); BUTTON_SetBitmapEx(hItem, BUTTON_BI_UNPRESSED, &bmBulbOff, 4, 4); break; case WM_NOTIFY_PARENT: Id = WM_GetId(pMsg->hWinSrc); NCode = pMsg->Data.v; //hItem = WM_GetDialogItem(pMsg->hWin, Id); if(NCode == WM_NOTIFICATION_RELEASED) { switch(Id) { case ID_Sequence_Delay: // Notifications sent by 'Sequence_Delay' //create the dialog to change the EDIT Box value ShowEditValue(_hManual, Sequence_Delay); break; case ID_Exit: // Notifications sent by 'Exit' WM_DeleteWindow(_hManual); MainTask(); break; case ID_ScreenOff: // Notifications sent by 'Screen' toogleBackLight(); break; } } break; case WM_PAINT: //draw background GUI_DrawBitmap(&bmBackGround, 0, 0); // show free/used memory ShowMem(); break; case WM_NOTIFICATION_CHILD_DELETED: //update here the EDIT box that was chaged in WM_NOTIFICATION_VALUE_CHANGED of slider and spin EDIT_SetDecMode(hItem, arrProfile[Sequence_Delay], 0, maxProfile[Sequence_Delay], 0, GUI_EDIT_NORMAL); break; default: WM_DefaultProc(pMsg); break; }}
      4. static void _InitManual(void) { _hManual = GUI_CreateDialogBox(_aDialogCreate, GUI_COUNTOF(_aDialogCreate), _cbDialog, WM_HBKWIN, 0, 0);}
      5. void ExecManual(void) { _InitManual(); WM_SetFocus(_hManual);}
      NOTE: I remove irrelevant code

      I have the following questions: related to the above code

      1. In the dialog creation if i use myItem then the dialog is not created
      GUI_CreateDialogBox(_aDialogCreate, GUI_COUNTOF(_aDialogCreate), _cbDialog, myItem, 0, 0);


      if i use GUI_CreateDialogBox(_aDialogCreate, GUI_COUNTOF(_aDialogCreate), _cbDialog, WM_HBKWIN, 0, 0); then is created but it will be the child of the desktop, correct?
      How shall i proceed in order to make the dialog child of the ID_ManualMenu window?


      2. When i delete the dialog i need to notify the ID_ManualMenu window that the global array is changed and it needs to update the value of the Edit box
      Is the WM_NOTIFICATION_CHILD_DELETED the correct way to do it? I see may examples using WM_SendMessageNoPara but i can only make this work inside the window, not between a window and a dialog


      3. Is there a place where i can find the range of values used for default IDs? I try to define my own ID's but i am afraid that i will overlap some predefined ones



      Thank you

    • All point solved
      1. I was not giving the correct handle
      2.In the Main window i use

      case WM_USER:
      hItem = WM_GetDialogItem(pMsg->hWin, ID_Sequence_Delay);
      EDIT_SetDecMode(hItem, arrProfile[Sequence_Delay], 0, maxProfile[Sequence_Delay], 0, GUI_EDIT_NORMAL);
      break;
      and in the dialog

      arrProfile[myItemIndex] = SPINBOX_GetValue(hSpin);
      WM_SendMessageNoPara(parentItem, WM_USER);
      WM_DeleteWindow(pMsg->hWin);

      3. I found the values in GUI.h and WM.H
      :thumbsup:
