Request 2

OS3.9 requester.class

I open a string requester with a chooser gadget with 2 options:

	
        if (!(Requester=NewObject(RequesterClass,NULL,
		REQ_TitleText,					Title,
		REQ_Type,						2,
		REQ_BodyText,					VABuffer,
		REQ_GadgetText,					Gadgets,
		REQS_Buffer,					StrBuffer,
		REQS_MaxChars,					MaxChars,
		REQS_ChooserArray,				ChooserArray,
		REQS_ChooserActive,				ChooserActive,
	TAG_END)))
		return(-99);
	Result=DoMethod(Requester,RM_OPENREQ,NULL,Window,NULL);
	DisposeObject(Requester);

I can't find out what the choice is for the chooser gadget. My variable ChooserActive never changes. Is this a bug?

By specifying REQS_ChooserActive on the NewObject call, you set the current active entry.

In order to get the current entry, you have to call GetAttr(REQS_ChooserActive,Requester,&ChooserActive) after DoMethod returns.

BTW, the question if it is a bug is silly. Think about it. This is C, not C++. C uses value parameters everywhere. If you give a variable to a subroutine, the subroutine only ever gets its value, it can never change the contents of the variable. If the subroutine shall be able to change the contents, the parameter has to be a pointer to the variable, not the variable itself.

Point well taken.

I couldn't find any example using the GetAttr() call.

Thank you again!
