Used to indicate which fields of a <a class="link" href="gdk-Windows.html#GdkGeometry"><span class="type">GdkGeometry</span></a> struct should be paid attention
to. Also, the presence/absence of <em class="parameter"><code>GDK_HINT_POS</code></em>, <em class="parameter"><code>GDK_HINT_USER_POS</code></em>, and

<p>
The <a class="link" href="gdk-Windows.html#GdkGeometry"><span class="type">GdkGeometry</span></a> struct gives the window manager information about 
a window's geometry constraints. Normally you would set these on 
the GTK+ level using <a
href="/usr/share/gtk-doc/html/gtk/GtkWindow.html#gtk-window-set-geometry-hints"
><code class="function">gtk_window_set_geometry_hints()</code></a>. <a
href="/usr/share/gtk-doc/html/gtk/GtkWindow.html"
><span class="type">GtkWindow</span></a> 
then sets the hints on the <a class="link" href="gdk-Windows.html#GdkWindow"><span class="type">GdkWindow</span></a> it creates.
</p>
<p>
<a class="link" href="gdk-Windows.html#gdk-window-set-geometry-hints"><code class="function">gdk_window_set_geometry_hints()</code></a> expects the hints to be fully valid already and
simply passes them to the window manager; in contrast,
<a
href="/usr/share/gtk-doc/html/gtk/GtkWindow.html#gtk-window-set-geometry-hints"
><code class="function">gtk_window_set_geometry_hints()</code></a> performs some interpretation. For example,
<a
href="/usr/share/gtk-doc/html/gtk/GtkWindow.html"
><span class="type">GtkWindow</span></a> will apply the hints to the geometry widget instead of the toplevel
window, if you set a geometry widget. Also, the
<em class="parameter"><code>min_width</code></em>/<em class="parameter"><code>min_height</code></em>/<em class="parameter"><code>max_width</code></em>/<em class="parameter"><code>max_height</code></em> fields may be set to -1, and
<a
href="/usr/share/gtk-doc/html/gtk/GtkWindow.html"
><span class="type">GtkWindow</span></a> will substitute the size request of the window or geometry widget. If
the minimum size hint is not provided, <a
href="/usr/share/gtk-doc/html/gtk/GtkWindow.html"
><span class="type">GtkWindow</span></a> will use its requisition as
the minimum size.  If the minimum size is provided and a geometry widget is set,
<a
href="/usr/share/gtk-doc/html/gtk/GtkWindow.html"
><span class="type">GtkWindow</span></a> will take the minimum size as the minimum size of the geometry widget
rather than the entire window. The base size is treated similarly.
</p>
<p>
The canonical use-case for <a
href="/usr/share/gtk-doc/html/gtk/GtkWindow.html#gtk-window-set-geometry-hints"
><code class="function">gtk_window_set_geometry_hints()</code></a> is to get a terminal
widget to resize properly. Here, the terminal text area should be the geometry
widget; <a
href="/usr/share/gtk-doc/html/gtk/GtkWindow.html"
><span class="type">GtkWindow</span></a> will then automatically set the
