示例1: color_tear_drag

{
colorTearInfo *tearInfo = (colorTearInfo *) data;
uint32 buttons = 1;

ColorMenu *menu = tearInfo->parent;

BView *view = tearInfo->someView;
// It might seem a good idea to use `menu' as the view, but
// this gave errors: `Method requires owner but doesn't have one'.
delete tearInfo; // The caller doesn't do this (race condition otherwise)
// printf ("Entering loop; view = %p\n", view);
while (buttons)

}示例2: BWindow

Since there is no method to retrieve this in the Be API without a view,
this looks a bit more complicated.
*/
