| ctTree |
|
|
ctTree is a
navigational hierarchical tree / outline control
offering
extensive presentation, interaction, and print functionality
ideal for document management, index entries and file directory
structures
 for
example. ctTree has been designed for high volume data
environments where performance, compatibility and functionality
are must-have requirements for enterprise and commercial
software solutions. ctTree consists of a series of node
objects. Each node may have its own text (or label), bitmaps,
check boxes and radio buttons. Each node item in the list may
also have subordinate items or children. These children are
represented as indented levels. When a parent item is expanded,
its immediate child items become visible. When the parent item
is collapsed, child items are hidden. |

|
XML Support : All data,
including presentation detail and style settings, consumed in
ctTree can be imported from or exported to an XML file. XML
Styles data is easily consumed between other supported DBI
components offering developers an economical method for
maintaining presentations and future VISTA styles. |
|
|
|
Export to Image : Use
the custom export-to-image method to easily create JPEG image
file displaying the ctTree View's contents. |
|
|
|
XP Fill Styles : The background of the title, header, and
main can all be colored with different fill styles. Similar
styles to those found in the new GDI+ drawing routines for .NET
including patterns for horizontal, vertical, diagonal,
horizontal-bump, vertical-bump, pyramid, diamond, circular and
elliptical gradient fills. |
 |
|
Printing :
Built in printing makes it easy to print
reports and data presented in the TreeView. Support for a wide
variety of paper sizes, custom properties and events allow the
control to accommodate unconventional paper sizes. Additional
developer controlled page breaks, footers,
page numbers, and printer handle features offer precision
reporting and data presentations. |
|
|
|
Node Display Features :
ctTree can display a variety of different items in a
node. With the actual text for the node, nodes can show
"Plus/Minus" picture, "Open / Close / Leaf" picture, an
independent bitmap image, and Tree Lines. |
|
|
Tool Tips : ctTree can display three
different types of tool tips.
- Line Tips appear when the mouse moves over the
text of a node.
- Parent Tips appear when the mouse moves over the
line area of and the parent of that node is not visible.
- Scroll Tips appear when the vertical scroll bar
is being moved.

| Edit Node Text :
ctTree's first column can be set to an edit mode.
End-users may enter or edit node text by selecting it with a
mouse. |
| |
| Sub-Text : Each node item can contain
its regular text as well as some sub-text. |
| |
|
Node Cargo and Node Data : ctTree
includes non-visible properties into which text strings (cargo)
or integer (data) may be associated with specific nodes. This
feature is perfect for storing a records key information. The
FindData and FindNext methods provide the ability to locate
nodes according to these hidden data values. |
|
|
|
Virtual Mode :
By default, data added to ctTree is managed in global memory.
However, if demands on memory become excessive, ctTree includes
a virtual mode that queries the host program for appropriate
text for each node when it is required for display. |
| |
| Check Box Support : Support for check
boxes in any cell in the control. Support for custom (user
supplied) check box images. |
| |
| Radio Button Support : Support for
child nodes to be group and set up with radio buttons (first
column only). Support for custom (user supplied) radio button
images. |
| |
| Multi-Select : Support for
multi-select. |
|
Internal Image List
:
An internal image list can be used to assign images
to cells and column headers of the list control. |
 |
| Column Designer Property Page
: Design all columns through the controls property pages. |
| |
|
Drag and Drop
: Drag items into and out of the tree. |
|
Masked Bitmaps
: Support for masked bitmaps. |
| |
|
Load Directory :
The tree can load the current contents of a directory directly
into itself. |
|
|
| Column Data Types : Columns can be
defined as text, numeric, or date/time. This now aids in the
column sorts. |
| Header Items : List items can be set
up as headers. Header will not be broken up be defined columns. |
| |
| Single and Multi-column Sort : Sorts
the list on values contained in any one, or combination of up to
three columns simultaneously. Sorts can be based on column data
type (i.e. text, numeric, or dates) |
