Maximization</A +></H3 +><P +>Maximization is a very old feature of Window Managers. There was even a ZoomedState +in early ICCCM drafts. Maximizing a window should give it as much of the +screen area as possible (this may not be the full screen area, but only +a smaller 'workarea', since the Window Manager may have reserved certain areas for other +windows). A Window Manager is expected to remember the geometry of a maximized window +and restore it upon de-maximization. Modern Window Managers typically allow separate +horizontal and vertical maximization.</P +><P +>With the introduction of the Xinerama extension in X11 R6.4, maximization +has become more involved. Xinerama allows a screen to span multiple +monitors in a freely configurable geometry. In such a setting, maximizing +a window would ideally not grow it to fill the whole screen, but only the +monitor it is shown on. There are of course borderline cases for windows +crossing monitor boundaries, and 'real' maximization to the full screen may +sometimes be useful.</P +></DIV +><DIV +CLASS="SECT3" +><H3 +CLASS="SECT3" +><A +NAME="AEN34" +>2.1.2. Shading</A +></H3 +><P +>Some Desktop Environments offer shading (also known as rollup) as an alternative to +iconfication.

Modality</A +></H2 +><P +>The Window Manager _TRANSIENT_FOR hint of the ICCCM allows clients to specify that a +toplevel window may be closed before the client finishes. A typical example +of a transient window is a dialog. Some dialogs can be open for a long time, +while the user continues to work in the main window. Other dialogs have to be +closed before the user can continue to work in the main window. This property +is called modality. While clients can implement modal windows in an ICCCM +compliant way using the globally active input model, some Window Managers offer support +for handling modality.</P +></DIV +><DIV +CLASS="SECT2" +><H2 +CLASS="SECT2" +><A +NAME="LARGEDESKS" +>2.3.

Virtual Desktops</A +></H2 +><P +>Most X servers have only a single screen.

The size of the desktops +may be fixed or variable.
