get-screen-box

Arguments: &key prompt title no-dialog

Waits for the user to specify two corner positions on the screen, and returns a box made from those positions. To allow the specification of any screen positions without affecting whatever windows are at those positions (as might happen with a mouse click), the user must specify each position by placing the mouse cursor at the desired position and then pressing the control key.

If no-dialog is nil then a modal dialog first appears to explain the specification procedure to the user; if no-dialog is true then the dialog is skipped. If prompt is nil, then a general explanation appears in the dialog; otherwise prompt should be a similar string that may be customized to the particular application. title is either a string to serve as the title of the modal dialog or nil (the default) for no title.
