<h1>GtkPeriodic Struct Reference</h1><!-- doxytag: class="GtkPeriodic" -->
<p><code>#include <<a class="el" href="gtkperiodic_8h_source.html">gcu/gtkperiodic.h</a>></code></p>
<table border="0" cellpadding="0" cellspacing="0">

<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>The <a class="el" href="structGtkPeriodic.html">GtkPeriodic</a> Widget displays a Periodic table of the elements, each element being represented in a toggle button. A test program is available in the tests directory of the Gnome Chemistry Utils source archive (source in <a class="el" href="testgtkperiodic_8c.html">testgtkperiodic.c</a>). <hr/>
<h2>Signals</h2>
<p>This widget has one signal:</p>
<ul>
<li>"element-changed": void user_function (GtkWidget* periodic, guint Z, gpointer data). <dl><dt><b>Parameters:</b></dt><dd>
<table border="0" cellspacing="2" cellpadding="0">
<tr><td valign="top"></td><td valign="top"><em>periodic,:</em> </td><td>the object which received the signal. </td></tr>
<tr><td valign="top"></td><td valign="top"><em>Z,:</em> </td><td>the atomic number of the newly selected element or 0 if no element is selected. </td></tr>
<tr><td valign="top"></td><td valign="top"><em>data,:</em> </td><td>user data set when the signal handler was connected.</td></tr>
</table>
</dd>
</dl>
This signal is raised when the selected element changes in the widget.</li>
</ul>
<hr/>
<h2>Properties</h2>
<p>There are two properties:</p>
<ul>
<li>"can_unselect": gboolean (Read / Write). <br/>
When this property is set to TRUE, you can unselect the selected element by clicking on the active button, otherwise an element will always be selected. Default value is FALSE.</li>
</ul>
<ul>
<li>"color-style": GtkPeriodicColorStyle (Read / Write). <br/>
This property is used to set the coloring scheme used for the buttons when displaying the periodic table. There are two predefined values:<ul>
<li>GTK_PERIODIC_COLOR_NONE: the default Gtk theme is used.</li>
<li>GTK_PERIODIC_COLOR_DEFAULT: the default color for each element is used as returned by gcu_element_get_default_color. Other values can be added using <a class="el" href="gtkperiodic_8h.html#ac919ffad7e8ba5d497651faf98908601">gtk_periodic_add_color_scheme()</a>. Default value is GTK_PERIODIC_COLOR_NONE.</li>
</ul>
</li>
</ul>
<hr/>
<h2>Functions</h2>
<p>Functions related to the <a class="el" href="structGtkPeriodic.html">GtkPeriodic</a> Widget are described in the <a class="el" href="gtkperiodic_8h.html">gtkperiodic.h</a> page. </p>
<hr/>The documentation for this struct was generated from the following file:<ul>
