You can reproduce it by modify exmaple ~qt4.x.src/examples/draganddrop/draggableicons/dragwidget.cpp
Replace Line #110 ( drag->setPixmap(pixmap); ) with

Qt Code:

Switch view

Qt Code:       
static unsigned char drag_bits[] = {       0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,       0x00, 0x7f, 0x00, 0x00, 0x41, 0x00, 0x00, 0x41, 0x00, 0xff, 0xc1, 0x0f,       0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x7f, 0xf0, 0x0f,       0x40, 0x10, 0x00, 0x40, 0x10, 0x00, 0xc0, 0x1f, 0x00, 0x00, 0x00, 0x00,       0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00};
