The TreeView Table control
Overview of the TreeView Table control The TreeView Table control is a cross between the Table control and the TreeView control. This control is based on the structure of a Table control (column, row, cell) but it also contains a TreeView column that introduces the notion of tree structure. This notion does not exist in a Table control. A TreeView Table control allows you to perform a single selection or a multiple selection as well as a sort on the columns (sort by level, among sibling elements). The information displayed in the TreeView Table control can: - can be programmatically determined: this is referred to as a field. Programmatically populated hierarchical table.
 come from a variable: this is referred to as a field TreeView Table control based on a variable. - come from a data file or a query: this is referred to as an field Hierarchical table linked to a data file. Only TreeView Table controls linked to a data file loaded in memory are available. In this case, the control handles the records of the data file loaded in memory.
Creating a TreeView Table control To create a TreeView Table control: - On the "Creación" tab, in the "Datos" group,
- expand "Tabla y List Box" and select "TreeView Table".
- Click where you want to create the control in the window or page.
Nota: Las dimensiones del control están optimizadas para ocupar el espacio disponible en la posición especificada. Si no está conforme con el tamaño del control, pulse la tecla Ctrl + Z para restablecer el tamaño predeterminado del control.Control characteristics To view the characteristics of the control, select "Description" in the context menu. There are two types of information: - information about the entire TreeView Table control (simply select the field name).
- information about each column in the TreeView Table control (simply select the name of one of the columns).
Table and TreeView Table controls, as well as their columns, share most of their characteristics. For more details on the characteristics of Table controls, see: For more details on TreeView Table controls, see: TreeView column To choose the column containing the hierarchy: - Open the TreeView Table control description window.
- On the "General" tab, enter the number of the desired column in "Number of TreeView column".
Handling the nodes of the tree structure programmatically To modify the images of the treeview nodes in a TreeView Table control, use the following properties: To easily handle a TreeView Table control, you must be familiar with the following vocabulary: | | | Name | Definition |
|---|
| Selection bar | Used to view the selected element. A specific color is used in most cases. | | Branch | Part of the tree structure that can define a path:- from the root to a leaf,
- from a node to another node,
- from a node to a leaf,
- from the root to a node.
| | Element | Generic name corresponding to the contents of a tree: Root, Node or Leaf are elements of a tree structure in a hierarchical table | | Leaf | Last element of the tree structure. There are no lower levels. | | Node | Intermediate level, can have higher levels (also called "Parent" levels) and lower levels (also called "Child" levels).
Note: the root and leaves correspond to specific nodes. | | Root | First element in the tree structure of the TreeView Table. The entire tree structure can be expanded from this element. |
Swapping the Table/TreeView Table controls A Treeview Table control can be automatically transformed into a Table control and conversely: - Select the TreeView Table control to transform.
- On the "Modificación" tab, in the "Transformaciones" group, expand "Refactorización y permutaciones" and select "Table / TreeView Table".
