Description

TmsDBTreeView represents a window that displays a hierarchical list of nodes, where each node is connected with the Database record. The component supports two types of the nodes: folders and files. A folder can include other nodes, and it is not connected with Database records containing the data. A file cannot include other nodes, but it is connected with the Database record, which contain the data. Each node is identified by four fields (a name, a status, a type, a position); each of the fields rewrites when its value is changing. The component supports the ‘drag and drop’ operation. For operations of addition, deletion, renaming of the nodes, uses shortcuts (Ins, Ctrl+ Ins, Del). The component works with the DataSet heirs. This component can be used for creation of the programs of a class of the information managers, various explorers etc. (example of the program using this component).

Features:

• Automatic sorting of the nodes (by type, by name); 
• Drag and Drop support; 
• Two types of the nodes (folders and files);
• Possibility of adding, deleting of the nodes; 
• Automatic transition to the Database record, connected with the selected node; 
• Storage information about each node (a name, a status (expand, collapse), a type, a state); 
• Shortcuts for the main operations with the nodes (adding of the folders \ files, deleting, renaming of the nodes).
