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.

ctTree features include:

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.

ctTree with custom images and colors assigned to some nodes.

• 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)
