// This widget `swallows' an X application. You pass the app window,
// and it will be reparented as a child of this widget.
//
// Resources:
//
// window
// The application window to be swallowed, or `None'.
//
// Realizing the widget requires WINDOW to be non-None.
//
//
// Callbacks:
//
// windowGoneCallback
// Called whenever the app window is destroyed or reparented.
//
// windowCreatedCallback
// Called whenever a new app window is created.
// Useful if you have to wait for the app window.
//
// Each callback is passed a `SwallowerInfo' structure pointer:
struct SwallowerInfo {
Window window;
XEvent *event;
};
// WINDOW is the window gone or created; EVENT is the event causing
// the callback.
//
// For `windowCreatedCallback' to function properly, this
// should be called whenever an X event is processed:
extern void SwallowerCheckEvents();
// Declare specific Swallower class and instance datatypes
typedef struct _SwallowerClassRec *SwallowerWidgetClass;
typedef struct _SwallowerRec *SwallowerWidget;
// Declare the class constant
extern WidgetClass swallowerWidgetClass;
// Define any new resources
#define XtNwindowGoneCallback "windowGoneCallback"
#define XtNwindowCreatedCallback "windowCreatedCallback"
