mouseDrag

mouseDrag(objectOrName, dx, dy)

mouseDrag(objectOrName, x, y, dx, dy)

mouseDrag(objectOrName, x, y, dx, dy, mouseButton)

mouseDrag(objectOrName, x, y, dx, dy, mouseButton, modifierState)

This function performs a mouse drag from the objectOrName widget to a position that is horizontally offset by dx pixels and vertically offset by dy pixels from the object's center (or from position x, y in the objectOrName widget's coordinates if these are specified). If you need to specify the mouse button or modifier state but don't want to specify the origin (because the center of the object is sufficient), pass 0 for the x coordinate and for the y coordinate.

By default the mouse is dragged from the middle of the object, but this can be changed by passing object-relative coordinates, x and y. The amount to drag, dx, dy, must be specified. By default MouseButton.LeftButton is used, but this can be changed by specifying the optional mouseButton argument. Similarly a default modifier state of Modifier.NoModifier is used, but this can be changed by specifying the modifierState argument. Note that to specify the modifier, the button must also be specified. See Windows Convenience Function Parameters for which values are valid for the mouseButton argument and for the modifierState argument.
