<p>
<a class="link" href="GwySelection.html" title="GwySelection"><span class="type">GwySelection</span></a> is an abstract class representing data selections. Particular
selection types are defined by vector layer modules.
</p>
<p>
Selections behave as flat arrays of coordinates. They are however logically
split into selection objects (points, lines, rectangles), characteristic for
each selection type. For example, to describe a horizontal line one needs
only one coordinate, for a point two coordinates are needed, rectangle or
arbitrary line need four. <a class="link" href="GwySelection.html#gwy-selection-get-object-size" title="gwy_selection_get_object_size ()"><code class="function">gwy_selection_get_object_size()</code></a> can be used to
generically determine the number of coordinates used to describe a one
selection object.
</p>
<p>
The number of selection objects in a selection can vary,
<a class="link" href="GwySelection.html#gwy-selection-set-max-objects" title="gwy_selection_set_max_objects ()"><code class="function">gwy_selection_set_max_objects()</code></a> sets the maximum possible number. Functions
