Separating and moving document objects using the movement of a wiper bar

摘要

A tool is provided for managing the available space in an electronic document. The tool can be used to move document objects and/or expand the boundaries or margins of a page to enable the addition or expansion of one or more document objects. The tool also can be used to move document objects and/or contract the boundaries of a page to reduce the available space on the page. A simple but user interface enables a user to easily move one or more document objects to create more space between document objects on the page or to eliminate space between document objects on the page. The user interface also enables a user to easily create more space within a particular document object. The user interface utilizes a wiper bar that spans the page or the document object and selects the objects that may be affected by creating or eliminating space on the page. A side wiper also may be provided to move document boundaries away from the objects on the page.
