color=navy><b>Gtk::CTree</b></font></tt> widget is used for showing a hierarchical tree to the user, for example a directory tree. <P> The tree is internally represented as a set of <tt><tt><font color=blue>GtkCTreeNode</font></tt></tt> structures. <P> The interface has much in common with the <tt><font color=navy><b>Gtk::CList</b></font></tt> widget: rows (nodes) can be selected by the user etc. <P> Positions in the tree are often indicated by two arguments, a parent and a sibling, both <tt><tt><font color=blue>GtkCTreeNode</font></tt></tt> pointers. If the parent is NULL, the position is at the root of the tree and if the sibling is NULL, it will be the last child of parent, otherwise it will be inserted just before the sibling.<br> <p> <hr noshade> <h2>Function Member Descriptions:</h2> <a name="1312"><font size=+1><b>Gtk::CTree::CTree</b></font></a> - Create tree with titles.<br> <hr size="1" width="70%" align="left" noshade="noshade"><tt></tt> <a href="Gtk%3A%3ACTree.html#1312"><tt><font color=blue><b>CTree</b></font></tt></a><tt>(<tt>const</tt> <a href="Gtk%3A%3ASArray.html"><tt><font color=navy><b>SArray</b></font></tt></a>& <tt><font color=blue>titles</font></tt>, <tt><font color=purple>gint</font></tt> <tt><font color=blue>tree_column</font></tt>=0)</tt>;<br><br> <a name="1313"><font size=+1><b>Gtk::CTree::CTree</b></font></a> - Create tree without titles.<br> <hr size="1" width="70%" align="left" noshade="noshade"><tt></tt> <a href="Gtk%3A%3ACTree.html#1313"><tt><font color=blue><b>CTree</b></font></tt></a><tt>(<tt><font color=purple>gint</font></tt> <tt><font color=blue>columns</font></tt>, <tt><font color=purple>gint</font></tt> <tt><font color=blue>tree_column</font></tt>=0)</tt>;<br><br> <a name="1303"><font size=+1><b>Gtk::CTree::gtkobj</b></font></a> - Returns the underlaying gtk+ object.<br> <hr size="1" width="70%" align="left" noshade="noshade"><tt><tt><font color=navy>GtkCTree</font></tt>*</tt> <a href="Gtk%3A%3ACTree.html#1303"><tt><font color=blue><b>gtkobj</b></font></tt></a><tt>()</tt>;<br><br> <a name="1305"><font size=+1><b>Gtk::CTree::isA</b></font></a> - Returns true if object is this type.<br> <hr size="1" width="70%" align="left" noshade="noshade"><tt><tt>static</tt> <tt><font color=purple>bool</font></tt></tt> <a href="Gtk%3A%3ACTree.html#1305"><tt><font color=blue><b>isA</b></font></tt></a><tt>(<a href="Gtk%3A%3AObject.html"><tt><font color=navy><b>Object</b></font></tt></a>* <tt><font color=blue>object</font></tt>)</tt>;<br><br> <a name="1314"><font size=+1><b>Gtk::CTree::is_hot_spot</b></font></a> - Used to determine if a particular coordinat lies on an expander button.<br> <hr size="1" width="70%" align="left" noshade="noshade"><tt><tt><font color=purple>bool</font></tt></tt> <a href="Gtk%3A%3ACTree.html#1314"><tt><font color=blue><b>is_hot_spot</b></font></tt></a><tt>(<tt><font color=purple>gint</font></tt> <tt><font color=blue>x</font></tt>, <tt><font color=purple>gint</font></tt> <tt><font color=blue>y</font></tt>)</tt>;<br><blockquote> x, y: The coordinates to check.
