Using a TTreeView to illustrate the relationship of master-detail query can greatly add to the user interface of you application. Not only does this process add to the UI, but it is also easy to do! Lets say there are two tables on a form, the first table is linked to DBDemos->Customer and the other table is linked to DBDemos->Orders. The TreeView component is used to display an hierarchical list of nodes - similar to the directory view in Windows Explorer. Each node is an instance of TTreeNode. TTreeView.Items (an instance of TTreeNodes) manages the node collection. In a basic tree list, the nodes are just text. It is also possible to have the nodes associated with objects. The idea behind this section is to provide basic and advanced example applications for people to download and see how things are done in Delphi, especially the VCL.The source code is stored at CodeGear's CodeCentral.Many articles in the references category have accompanying source code.
