Using an Existing Widget
Most of the classes that inherit from the IlvView class define a constructor that specifies an existing widget to be used, instead of your having to create one. Here is how to create an IlvView object from a widget:
IlvDisplay* display = ... // display initialization
// Create a DrawingArea widget
Widget drawingArea =
XtVaCreateManagedWidget("ilvview",
xmDrawingAreaWidgetClass, parent,
XmNwidth, 100,
XmNheight, 100,
0);
// Realize this widget
XtRealizeWidget(drawingArea);
// Create a IlvView object from this widget.
IlvView* aView = new IlvView(display, drawingArea);
The only restriction is that the widget you use must already be realized (in the Xt terminology, that is, the widget must have a window) before you call the constructor of IlvView.
