Object representing a physical screen <a class="el" href="classGdk_1_1Screen.html">Gdk::Screen</a> objects are the GDK representation of a physical screen.
<p>
It is used throughout GDK and GTK+ to specify which screen the top level windows are to be displayed on. It is also used to query the screen specification and default settings such as the default colormap (<a class="el" href="classGdk_1_1Screen.html#657337da43c0b86c9d02693f8b849091">get_default_colormap()</a>), the screen width (<a class="el" href="classGdk_1_1Screen.html#245c84610e80f9ab1ce3886702e83a27">get_width()</a>), etc. Note that a screen may consist of multiple monitors which are merged to form a large screen area.
