TColorPickerButton is a special speed button which can be used to let the user select a specific color. The control does not use the standard Windows color dialog, but uses a popup window very similar to the one in Office97, which has been improved a lot to support the task of picking one color out of millions. Included is also the ability to pick one of the predefined system colors (e.g. clBtnFace).

Virtual Treeview can be characterized by these few core capabilities
  • Virtual Treeview is extremely fast and designed for high speed access.
  • Virtual Treeview is memory sparing which is the premise for speed and capacity.
  • Virtual Treeview is a high capacity control. Classical trees need ~30 MB for 200 000 nodes (if they can hold so many nodes at all). Virtual Treeview needs only ~60 MB for 1 000 000 (that's one million!) nodes.
  • Virtual Tree's design is satisfying professional demands and implements a virtual paradigm, which allows for separating structure and data. This in turn allows for small memory requirements etc.
  • The virtual paradigm required also a new serialization concept to make it possible to save and store a tree to/from a stream (including all user data).
  • Correct system integration by supporting Unicode and OLE Drag'n drop as well as OLE clipboard operations.
  • Virtual Treeview is highly customizable. Several levels of customization support ease the life of component developers writing totally new descentants and application developers who just want to give the tree a little different appearance.
