Run once the control has been filled. This code is used to select an element in the TreeView Table control, to add or modify an element.
Entry in the treeview tableRun when the control takes focus.
Exit from the treeview tableRun when moving from one control to another (TAB key, selecting another control with the mouse, etc.).
Entry in input in a row of the treeview tableRun when the user selects a row to perform an input in this row.
Exit from a row of the treeview tableRun when moving from one row or control to another (TAB key, selecting another control with the mouse, etc.).
Row displayRun when a new row must be displayed in the TreeView Table control, for example when one of the following actions is performed: re-display the control, scroll or move in the control, ...
Selecting a rowRun when the user selects a row (without input).
Collapsing/Expanding a nodeRun when the user expands or collapses a node.
Remark: The syntax TableName[TableName] used in this event allows you to know the number of the row that is collapsed/expanded.
(*) By default, the event "Initializing" of each control is run according to the order in which the controls were created in the window. To modify this runtime order:
  1. Select "Windows .. Edit the initialization order".On the "Window" pane, in the "Order" group, click "Initialization".

Optional events
Several optional events can be managed.
To manage an optional event, simply select it in the icon bar of the code window (bottom right).
You can manage, for example:
  • the control rollover with the mouse,
  • the left mouse button down, up, with a double click,
  • the right mouse button down, up, with double click,
  • the mouse wheel, etc.
Filtering records (browsing TreeView Table control only)
The event "Filtering the records" is run right after a row of the TreeView Table control is displayed. Therefore, it is run:
  • when initializing the control.
  • whenever a row is displayed in the TreeView Table control.
This event is used to filter the records displayed in the TreeView Table control.
To implement a filter, the event "Filtering the records" must return a value:
  • True to specify that the record matches to the filter and that it must be displayed.
  • False to specify that the record does not match the filter and that it must not be displayed.
  • Cancel to stop reading the data source of the TreeView Table control (very rare case).
Example:
// -- Filter the records
// Displays the customers who placed orders exceeding 3000 Euros
IF Order.TotalIOT >= 3000 THEN
RESULT True
ELSE
RESULT False
END
In this code, the data used affects the record currently read by the TreeView Table control. This data comes from the date file or from the query linked to the control.
If an automatic filter is applied on the TreeView Table control (TableEnableFilter or filter enabled directly by the user), the filter defined by the event "Filtering records" is added to the automatic filter.
Before displaying the automatic tooltip of scrollbar
Versions 17 and later
WINDEV The tooltip for the scrollbar of TreeView Table controls is displayed when the user clicks the "box" of the vertical scrollbar in the treeview table.
This tooltip contains the following information by default:
  • Range of rows currently displayed in the TreeView Table control.
  • Total number of rows in the TreeView Table control.
  • Information about the element currently displayed in the first row of the control in the sorted column.
The optional event "Before displaying the automatic tooltip of the scrollbar" is run just before the tooltip is displayed. This allows you for example to display a specific text in the tooltip of the TreeView Table control with ..ToolTip.
