Super class

Inherited by

Background

Popobject class takes a MUI object as parameter uses this one as popup. You can e.g. simply create a listview object with some entries and the popobject class will create a window around it and display it when the user hits the popup button.

Using this class instead of creating the popup windows yourself prevents you from having lots of problems. Think twice before deciding to make you own popups!

MUIA_Popobject_Follow

NAME

MUIA_Popobject_Follow -- V7 [ISG], BOOL, 0x80424cb5

FUNCTION

Setting this attribute causes the popup window to follow its parent window when its moved.

Defaults to TRUE.

MUIA_Popobject_Light

NAME

MUIA_Popobject_Light -- V7 [ISG], BOOL, 0x8042a5a3

FUNCTION

This attribute causes the popup window to be border and titleless.

Defaults to TRUE

MUIA_Popobject_Object

NAME

MUIA_Popobject_Object -- V7 [I.G], Object *, 0x804293e3

FUNCTION

Specify the object to pop up. Usually this is a relatively simple thing like a single listview, but you can of course use group class here and make rather complex popups. As with all other MUI classes, the object here gets disposed when the popobject is disposed.

EXAMPLE

pop = PopobjectObject,
  MUIA_Popstring_String, KeyString(0, 60, 'n'),
  MUIA_Popstring_Button, PopButton(MUII_PopUp),
  MUIA_Popobject_StrObjHook, &StrObjHook,
  MUIA_Popobject_ObjStrHook, &ObjStrHook,
  MUIA_Popobject_Object, ListviewObject,
    MUIA_Listview_List, ListObject,
      InputListFrame,
      MUIA_List_SourceArray, PopNames,
      End,
    End,
  End;

MUIA_Popobject_ObjStrHook

NAME

MUIA_Popobject_ObjStrHook -- V7 [ISG], struct Hook *, 0x8042db44

FUNCTION

When a popup is closed, this hook is called. You can examine the state of your MUIA_Popobject_Object and set the contents of the string gadget respectively. The hook receives a pointer to itself in A0, a pointer to your MUIA_Popobject_Object in A2 and a pointer to the embedded string object in A1.

The hook will only be called when your popup is closed with a success value of TRUE. Otherwise, MUI closes the popup without taking further actions, just as if had never opened.

Since MUI doesn't know anything about your MUIA_Popobject_Object, it's your task to tell when your popup is finished. You can terminate popups at any time by sending a MUIM_Popstring_Close method:

EXAMPLE

/* A double click terminates the popping list with a successful
   return value. */

DoMethod(plist, MUIM_Notify, MUIA_Listview_DoubleClick, TRUE,
  pop, 2,
  MUIM_Popstring_Close, TRUE);

SAVEDS ASM VOID ObjStrFunc(REG(a2) Object *list,REG(a1) Object *str)
{
  char *x;

  DoMethod(list, MUIM_List_GetEntry, MUIV_List_GetEntry_Active, &x);
  set(str, MUIA_String_Contents, x);
}

MUIA_Popobject_StrObjHook

NAME

MUIA_Popobject_StrObjHook -- V7 [ISG], struct Hook *, 0x8042fbe1

FUNCTION

Before the popup opens, this hook is called. You can use it to prepare your MUIA_Popobject_Object according to the contents of the string gadget. The hook receives a pointer to itself in A0, a pointer to your MUIA_Popobject_Object in A2 and a pointer to the embedded string object in A1.

Return TRUE if you want the popup to appear, FALSE otherwise.

EXAMPLE

SAVEDS ASM LONG StrObjFunc(REG(a2) Object *list, REG(a1) Object *str)
{
  char *x,*s;
  int i;

  get(str, MUIA_String_Contents ,&s);

  for(i=0;;i++)
  {
    DoMethod(list, MUIM_List_GetEntry, i, &x);
    if(x == NULL)
    {
      set(list, MUIA_List_Active, MUIV_List_Active_Off);
      break;
    }
    else if(stricmp(x, s) == 0)
    {
      set(list, MUIA_List_Active, i);
      break;
    }
  }

  returnTRUE;
}

MUIA_Popobject_Volatile

NAME

MUIA_Popobject_Volatile -- V7 [ISG], BOOL, 0x804252ec

FUNCTION

Setting this attribute causes the popup window to disappear when the corresponding popobject disappears, e.g. because its in a page group and the user toggled the page. When the popobject appears again, the popup window appears also.

Defaults to TRUE.

MUIA_Popobject_WindowHook

NAME

MUIA_Popobject_WindowHook -- V9 [ISG], struct Hook *, 0x8042f194

FUNCTION

If specified, this hook is called immediately after the popup's window object has been created but before this window is opened. You might e.g. want to add a cycle chain for the popup window here.

The hook is called with a pointer to the pop object (MUIA_Popobject_Object) in A2 and with a pointer to the window object that MUI generated to handle the popup in A1.

EXAMPLE

/* pop is a simple listview, just set the windows
** default object to this to enable keyboard control */

SAVEDS ASM VOID WindowFunc(REG(a2) Object *pop,REG(a1) Object *win)
{
  set(win, MUIA_Window_DefaultObject, pop);
}
