Each document opened using XQuad is displayed in a window on the desktop. A document window is similar to an "application window" in UNIX; that is, it can be moved, horizontally or vertically re-sized, made into an icon, maximized for size, or closed.

Screen shot: Document window.

All document windows in XQuad are set up in the following manner (vertically and horizontally): 

1. The Window Management Interface is all the area around the window, dressing it. The interface operates in a standard manner, like all multi-window systems. The outline of an active document is mauve; that of an inactive document is gray. All functions effected through menubars and icons act only upon the active document. Clicking on the window of an inactive document activates it. The upper horizontal toolbar is made up of:
    
   • The Closing a Document button. This button performs the same function as "File / Close".
      
   • The Title Bar, which displays the document's name. Clicking on the title bar of a document shifts its window to the foreground and activates the document. The document window may be moved by clicking and holding on the title bar with the left mouse button and releasing it elsewhere on the desktop.
      
   • The create icon button shifts the document window to icon representation.
      
   • The maximize button enlarges the document window to the size of the desktop, thus shifting the document to maximum window form..

   The left, right, and bottom sides as well as the lower left and lower right corners are used to re-size the window on the desktop by taking one of these sides or one of the two corners and stretching the window horizontally, vertically, or diagonally, then releasing.

2. The header origin, the columns headers and the rows headers. In this area, it is possible to select one or several whole columns or rows and to change the rows heights or the columns widths.
    
3. The cell sheet. The entered data is viewable in the cell sheet. Graphic frames, which can be altered, are displayed over it.
    
4. The Scrollbars. Two sliders provide for horizontal and vertical movement of the visible part of the cell sheet. The slider size is proportional to the visible part of the used area of the cell sheet. To go beyond the used area, you have to locate the cursor to his home position (column A for the horizontal slider or the line 1 for the vertical slider) and then click on the arrow without releasing the mouse button immediately.
