I want to drag & drop an object like rectangle , would you please give me the code and intterupt of it?
thank you in advance

a) What CPU?

b) What OS?

c) Is this a stock GUI like Windows or X, or a roll your own project where you're doing all the graphics yourself the hard way?

You will need to study the various functions available in the bios int 10h. You won't find any ready made functions to "drag and drop" (I don't think); you will just have to keep redrawing the rectangle as the mouse moves; each time saving the original screen contents so that they can be restored each time the mouse moves to a new location.
