+<p>
+The normal way to reparent (ie change the owner) of a widget should be
+to use the function:
+
+<tscreen><verb>
+void gtk_widget_reparent (GtkWidget *widget,
+ GtkWidget *new_parent)
+</verb></tscreen>
+
+But this is only a "should be" since this function does not correctly
+do its job on some specific widgets. The main goal of
+gtk_widget_reparent() is to avoid unrealizing widget if both widget
+and new_parent are realized (in this case, widget->window is
+successfully reparented). The problem here is that some widgets in the
+GTK+ hierarchy have multiple attached X subwindows and this is notably
+the case for the GtkSpinButton widget. For those,
+gtk_widget_reparent() will fail by leaving an unrealized child window
+where it should not.
+
+To avoid this problem, simply use the following code snippet:
+
+<tscreen><verb>
+ gtk_widget_ref(widget);
+ gtk_container_remove(GTK_CONTAINER(old_parent), widget);
+ gtk_container_add(GTK_CONTAINER(new_parent), widget);

this function when it acts on a window, you may want to use the
<tt/gtk_window_set_policy/ function. The definition of these functions

+
+void gtk_window_set_policy (GtkWindow *window,

+ gint allow_grow,
+ gint auto_shrink);
</verb></tscreen>
<tt/Auto_shrink/ will automatically shrink the window when the
auto_shrink = FALSE
</verb></tscreen>
+The <tt/gtk_widget_set_usize()/ functions is not the easiest way to
+set a window size since you cannot decrease this window size with
+another call to this function unless you call it twice, as in:
+
+ gtk_widget_set_usize(your_widget, -1, -1);
+ gtk_widget_set_usize(your_widget, new_x_size, new_y_size);
+
+Another way to set the size of and/or move a window is to use the
+<tt/gdk_window_move_resize()/ function which uses to work fine both to
+grow or to shrink the window:
+
+ gdk_window_move_resize(window->window,
