42Drag and Drop support is implemented on Linux via Xdnd, the\n\
43drag and drop protocol for X window system, and on Windows\n\
45Users can selects something in ROOT with a mouse press, drags\n\
46it (moves the mouse while keeping the mouse button pressed) and\n\
47releases the mouse button somewhere else. When the button is\n\
48released the selected data is \"dropped\" at that location. This\n\
49way, a histogram from an opened ROOT file in the browser can be\n\
50dragged to any TCanvas. A script file from the browser can be\n\
51dropped to a TGTextView or TGTextEdit widget in TGTextEditor.\n\
52On Linux, it is possible to drag objects between ROOT and an\n\
53external application. For example to drag a macro file from the\n\
54ROOT browser to the Kate editor. On Windows, drag and drop works\n\
55only within a single ROOT application, but it is possible to drag\n\
56from the Windows Explorer to ROOT (e.g. a picture file to a canvas\n\
57or a text file to a text editor).\n\
