|
|
* The XtArgCollector class is simply a dynamic array of Args.
|
|
* It is useful to build an ArgList to pass as an argument to
|
|
* XtSetValues. This is a way to collect resources and values
|
|
* over several functions and then finally set them at another
|
|
* point. This can help prevent multiple redisplays in widgets
|
|
* like XmList which don't have a DisableRedisplay convenience
|
|
* function like XmText. It's a class for setting resources
|
|
* similar to the following:
|
|
* n=0;
|
|
* XtSetArg (args[n], XmNmarginHeight, 5); n++
|
|
* XtSetValues (widget, args, n);
