InitDialogItems

The InitDialogItems function translates an array of InitDialogItem structures to an array of FarDialogItem structures.

Attention!

The InitDialogItems function is not part of the standard API.

void InitDialogItems(
       const struct InitDialogItem *Init,
       struct FarDialogItem *Item,
       int ItemsNumber
)
{
  int I;
  const struct InitDialogItem *PInit=Init;
  struct FarDialogItem *PItem=Item;
  for (I=0; I < ItemsNumber; I++,PItem++,PInit++)
  {
    PItem->Type=PInit->Type;
    PItem->X1=PInit->X1;
    PItem->Y1=PInit->Y1;
    PItem->X2=PInit->X2;
    PItem->Y2=PInit->Y2;
    PItem->Focus=PInit->Focus;
    PItem->Reserved=PInit->Selected;
    PItem->Flags=PInit->Flags;
    PItem->DefaultButton=PInit->DefaultButton;
    if ((unsigned int)PInit->Data < 2000)
      strcpy(PItem->Data,GetMsg((unsigned int)PInit->Data));
    else
      strcpy(PItem->Data,PInit->Data);
  }
}

Parameters

Init

Pointer to an array of InitDialogItem structures. Each array item defines one dialog item.

Item

Pointer to an array of FarDialogItem structures to initialize. Each array item will define one dialog item.

ItemsNumber

Number of elements in Init.

Return value

None.

Remarks

Use of the InitDialogItems function is reasoned by the following:
FarDialogItem.Data variable is large, that's why direct initalization of an array of FarDialogItem structures may significantly increase memory usage.

The example bellow shows how to use the InitDialogItems function and the InitDialogItem structure to create a dialog.

Example

TempPanel plugin configuration dialog sample:

int Config()
{
  struct InitDialogItem InitItems []={
    DI_DOUBLEBOX,3,1,72,8,0,0,0,0,(char *)MConfigTitle,
    DI_CHECKBOX,5,2,0,0,0,0,0,0,(char *)MConfigAddToDisksMenu,
    . . .
    DI_BUTTON,0,7,0,0,0,0,DIF_CENTERGROUP,1,(char *)MOk,
    DI_BUTTON,0,7,0,0,0,0,DIF_CENTERGROUP,0,(char *)MCancel
  };
  struct FarDialogItem DialogItems[sizeof(InitItems)/sizeof(InitItems[0])];
  . . .
  InitDialogItems(InitItems,DialogItems,sizeof(InitItems)/sizeof(InitItems[0]));
  . . .
  int ExitCode=Info.Dialog(Info.ModuleNumber,
                  -1,-1,76,10,
                  "TempCfg",DialogItems,
                  sizeof(DialogItems)/sizeof(DialogItems[0]));
  if (ExitCode != 7)
    return(FALSE);
. . .
}
