<module name="fpg_tree">
<short>This unit defines a tree view control</short>
<descr><p><printshort id="fpg_tree"/>. A tree view displays items in an indented
outline. The control provides buttons that allow nodes to be expanded and collapsed.
You can include icons with items' text labels and display different icons to
indicate whether a node is expanded or collapsed.</p>
</descr>
<element name="TfpgTreeView">
<short>Represents a window that displays a hierachy list of items</short>
<descr><p><printshort id="TfpgTreeView"/>. Examples of such hierachies can be
the headings in a document, the entries in a index, or the files and directories
on a disk.</p>
<p>Use TfpgTreeView to add an expanding and contracting outline to a form. Each node
in a tree view control consists of a label and a number of optional bitmapped images.
Each node can have a list of subnodes associated with it. By clicking on a node,
the user can expand or collapse the associated list of subnodes.</p>
<remark>There is basic column support, but this is still very experimental.</remark></descr>
</element>
<element name="TfpgTreeView.FullCollapse">
<short>Collapses all the nodes within a tree view control</short>
<descr><printshort id="TfpgTreeView.FullCollapse"/>. Call FullCollapse to hide
all the nodes in the tree view except those at the first level. All node buttons
will change from '-' to '+'.</descr>
<seealso>
<link id="TfpgTreeView.FullExpand"/>
</seealso>
</element>
<element name="TfpgTreeView.FullExpand">
<short>Expands all nodes within the tree view control</short>
<descr><printshort id="TfpgTreeView.FullExpand"/>. Call FullExpand to display
all the nodes in the tree view. All node buttons will change from '+' to '-'.</descr>

<element name="TfpgTreeView.GotoNextNodeUp">
<short>Moves the selection to the previous node up the tree</short>
</element>
<element name="TfpgTreeView.GotoNextNodeDown">
<short>Moves the selection to the next node down the tree</short>
</element>
<element name="TfpgTreeView.NextNode">
<short>Return the next node after ANode</short>
<descr><printshort id="TfpgTreeView.NextNode"/>. This function will step into child
nodes as well, to return the correct node. It works on the actual nodes in the tree,
and not just the visible nodes in the tree.</descr>

</element>
<element name="TfpgTreeView.PrevNode">
<short>Return the previous node starting from ANode</short>
<descr><printshort id="TfpgTreeView.PrevNode"/>. This function will step into child
nodes as well, to insure it returns the correct node. It works on the actual nodes
in the tree, and not just on the visible nodes.</descr>

</element>
<element name="TfpgTreeview.NextVisualNode">
<short>Return the next visible node starting from ANode</short>
<descr><printshort id="TfpgTreeview.NextVisualNode"/>. This works exactly the same
as <var>NextNode</var> function, but this time it only acts on nodes that are visible.</descr>

<element name="TfpgTreeview.PrevVisualNode">
<short>Return the previous visible node starting from ANode</short>

as <var>PrevNode</var> function, but this time it only acts on nodes that are visible.</descr>

<element name="TfpgTreeview.Font">
<short>This gives you read access to the internal Font resource</short>
<descr><printshort id="TfpgTreeview.Font"/>. If you want to change the font used
in the tree view, use the <link id="TfpgTreeview.FondDesc">FondDesc</link> property instead.</descr>

</element>
<element name="TfpgTreeview.RootNode">
<short>Returns the first node of the tree where all other nodes branch from</short>
<descr><printshort id="TfpgTreeview.RootNode"/>. This node is not a visible node, and
is the internal node all other nodes in the tree branches from.</descr>
</element>
<element name="TfpgTreeview.Selection">
<short>Specifies the selected node in the tree vie</short>
<descr><p><printshort id="TfpgTreeview.Selection"/>. Read <var>Selection</var> to access
the selected node of the tree view. If there is no selected node, the value returned
is nil.</p>
<p>Set <var>Selection</var> to set the node in the tree view. If the new node is
a child of a collapsed node, the tree view will automatically
expand the nodes and scroll the new selected node into view. As the parent nodes are
expanded, so the tree view will trigger the OnExpand event as well.</p></descr>
</element>
<element name="TfpgTreeview.ImageList">
<short>Refers to the image list associated with the tree view</short>
<descr><printshort id="TfpgTreeview.ImageList"/>. Use the <var>ImageList</var> to
provide a customised list of bitmaps that can be displayed with the node's text. Use
the node's <link id="TfpgTreeNode.ImageIndex">ImageIndex</link> property to specify the
bitmap that must be painted next to the node's text.</descr>

<element name="TfpgTreeview.PopupMenu">
<short>Identifies the pop-up menu associated with the tree view</short>

<short>Specifies the font used for the tree view</short>
<descr><printshort id="TfpgTreeview.FontDesc"/>. You can specify the font name and size
in the format <var>fontname-size:attributes</var>, or you can use any of the font
aliases that has been setup. A font alias is a short name for some specific font, font size
