get-line

Arguments: window-or-screen start-position &optional scroll-p cursor

Waits until the user presses or unpresses a mouse button, and then returns the current position of the mouse cursor in the stream coordinates of window-or-screen. The screen is the value returned by (screen *system*). See screen and *system*.

During the wait, a rubber-band line is continuously drawn between start-position and the current mouse position. If scroll-p is true, the window (identified by window-or-screen) will be scrolled if the cursor moves outside it. Sets the stream cursor to cursor while running. If the cursor argument is unspecified or t, a default is used (typically the cross-hair cursor).
