2002-01-19 Havoc Pennington <hp@pobox.com> * gtk/gtkwindow.c: link to new X11 section in a lot of places when mentioning the window manager. * gtk/gtkwidget.c (gtk_widget_hide_on_delete): don't mention window manager since we're portable. 2002-01-19 Havoc Pennington <hp@pobox.com> * gtk/x11.sgml: add a mostly-empty X11 section * gtk/framebuffer.sgml: make title consistent with windows section * gtk/tmpl/gtkdrawingarea.sgml: couple of fixes

On UNIX, the X backend is the default build for GTK+. So
|
|
you don't need to do anything special when compiling it,
|
|
and everything should "just work."

People coming from a Windows or MacOS background often find certain
|
|
aspects of the X Window System surprising. This section introduces
|
|
some basic X concepts at a high level. For more details, the book most
|
|
people use is called the <citetitle pubwork="book">Xlib Programming
|
|
Manual</citetitle> by Adrian Nye; this book is volume one in the
|
|
O'Reilly X Window System series.

Standards are another important resource if you're poking in low-level
|
|
X11 details, in particular the ICCCM and the Extended Window Manager
|
|
Hints specifications. <ulink
|
|
url="http://www.freedesktop.org/standards/">freedesktop.org</ulink>
|
|
has links to many relevant specifications.

<title>Server, client, window manager</title>
|
|
|
|
<para>
|
|
Other window systems typically put all their functionality in the
|
|
application itself. With X, each application involves three different
|
|
programs: the <firstterm>X server</firstterm>, the application (called
|
|
a <firstterm>client</firstterm> because it's a client of the X
|
|
server), and a special client called the <firstterm>window
|
|
manager</firstterm>.
|
|
</para>
|
|
|
|
<para>
|
|
The X server is in charge of managing resources, processing drawing
|
|
requests, and dispatching events such as keyboard and mouse events to
|
|
interested applications. So client applications can ask the X server
|
|
to create a window, draw a circle, or move windows around.
|
|
</para>
|
|
|
|
<para>
|
|
The window manager is in charge of rendering the frame or borders
|
|
around windows; it also has final say on the size of each window,
|
|
and window states such as minimized, maximized, and so forth.
|
|
On Windows and MacOS the application handles most of this.
|
|
On X11, if you wish to modify the window's state, or
|
|
change its frame, you must ask the window manager to do so on your
|
|
behalf, using an established <ulink
|
|
url="http://www.freedesktop.org/standards/">convention</ulink>.
|
|
</para>
|
|
|
|
<para>
|
|
GTK+ has functions for asking the window manager to do various things;
|
|
see for example <link
|
|
linkend="gtk-window-iconify">gtk_window_iconify()</link> or <link
|
|
linkend="gtk-window-maximize">gtk_window_maximize()</link> or <link
|
|
linkend="gtk-window-set-decorated">gtk_window_set_decorated()</link>.
|
|
Keep in mind that <link
|
|
linkend="gtk-window-move">gtk_window_move()</link> and window sizing
|
|
are ultimately controlled by the window manager as well and most
|
|
window managers <emphasis>will</emphasis> ignore certain requests from
|
|
time to time, in the interests of good user interface.
