• Native VCL component (not inherited from TCustomTreeView and does not require the use of the Common Controls DLL!).

• Compatible with Delphi 4, 5, 6 and C++ Builder 4,5.

• Fully compatible with the properties, events and methods of the TTreeView component - it can be a direct replacement for the TTreeView on pre-designed forms.

• Full standard windows help file describing all properties, events and methods of the component and related objects.

• Provides a base component (TCustomRBTreeView) for programmers who need to develop custom TRBTreeView components of their own.

• Supports right to left reading order for languages that requires it (like Hebrew, Arabic etc) - this support put the vertical scroll bar to the left, and changes the reading order of the text in each node.

• Save and load the tree to and from a text file.

• Save and load the tree to and from a memory stream.

• Print the tree to any canvas, particularly a printer one (with control over nodes size, tree position and lots more).

• Manage the tree nodes in design time with the TRBTreeNodes design-time editor: insert node, sub nodes, delete nodes, change the text etc.:

• Smooth scrolling by two proportional scrollbars when tree is bigger than the client area.

• Control the look of the tree:

  • Show/Hide expanding buttons.

  • Change size of expanding buttons.

  • Change colors of every aspect of the tree (connecting lines, nodes, background etc)

  • Change drawing style of connecting lines.

  • Show/Hide root lines.

  • Change nodes color, style, font, image, image side.

  • Control nodes height, width, vertical and horizontal spacing.

• If the built-in drawing is not enough, provide your own drawing routines by writing a simple event handler, here is an example (from the demo application in the component download package):

• Allows for the user to edit each node text in run-time using a popup text edit box (in-place editing).

• Events triggered when changing nodes, editing them, deleting, collapsing, expanding etc. - provide the programmer full control and feedback over the user operations.

Nodes Operations

• Add and insert new node into the tree.

• Delete nodes.

• Add and insert sub-nodes to the tree.

• Collapse and expand father nodes.

• Attach a 32 bits user defined value to each node.

• Attach a string value and an integer one to each node, and edit them in the design-time editor for further convenience.

• Control Nodes color, font, text, image, image side.

• Allow batch operations to be performed on the nodes without generating multiple refreshes on the tree.
