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!

NAME MUIA_Popobject_Follow -- (V7 ) [ISG], BOOL FUNCTION Setting this attribute causes the popup window to follow its parent window when its moved. Defaults to TRUE. SEE ALSO MUIA_Popobject_Light, MUIA_Popobject_Volatile.
NAME MUIA_Popobject_Light -- (V7 ) [ISG], BOOL FUNCTION This attribute causes the popup window to be border and titleless. Defaults to TRUE SEE ALSO MUIA_Popobject_Follow, MUIA_Popobject_Volatile
NAME MUIA_Popobject_Object -- (V7 ) [I.G], Object * 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; SEE ALSO MUIA_Popobject_StrObjHook, MUIA_Popobject_ObjStrHook, MUIA_Popobject_Light
NAME MUIA_Popobject_ObjStrHook -- (V7 ) [ISG], struct Hook * 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 anytime by sending a MUIM_Popstring_Close method: /* 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); EXAMPLE 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); }
NAME MUIA_Popobject_StrObjHook -- (V7 ) [ISG], struct Hook * 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) { set(list,MUIA_List_Active,MUIV_List_Active_Off); break; } else if (!stricmp(x,s)) { set(list,MUIA_List_Active,i); break; } } return(TRUE); } SEE ALSO MUIA_Popobject_ObjStrHook, MUIA_Popobject_Object, MUIA_Popobject_WindowHook
NAME MUIA_Popobject_Volatile -- (V7 ) [ISG], BOOL 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. SEE ALSO MUIA_Popobject_Light, MUIA_Popobject_Follow
NAME MUIA_Popobject_WindowHook -- (V9 ) [ISG], struct Hook * FUNCTION If specified, this hook is called immediately after the popups window objects 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); } SEE ALSO MUIA_Popobject_ObjStrHook, MUIA_Popobject_Object
