- Selection bar
- Runtime speed
TableItemStatus (Function) Returns the state of a node in a TreeView Table control: rolled up, unrolled or non-existent. Reminder At runtime, a node is unrolled when the "-" sign precedes the node name.
SWITCH TableItemStatus(TVT_Schedule, "Root" + TAB + "Node" + TAB + "Leaf2")
CASE taError: Trace("The node does not exist.")
CASE taExpanded: Trace("The node is unrolled.")
CASE taCollapsed: Trace("The node is wound.")
END
Sintaxis
Status of a node by specifying the row number Ocultar los detalles
<Result> = TableItemStatus(<TreeView Table control> [, <Row number>])
<Result>: Integer constant Status of specified node:
| | | taCollapse | The node is collapsed | | taError | Node not found | | taExpand | The node is expanded |
<TreeView Table control>: Control name Name of the TreeView Table control to be used. <Row number>: Optional integer Number of the row containing the node to use. If this parameter is not specified, the status of the node found in the current row is returned.
Status of a node by specifying its name Ocultar los detalles
<Result> = TableItemStatus(<TreeView Table control> [, <Node name>])
<Result>: Integer constant Status of specified node:
| | | taCollapse | The node is collapsed | | taError | Node not found | | taExpand | The node is expanded |
<TreeView Table control>: Control name Name of the TreeView Table control to be used. <Node name>: Optional character string Name of node to use. This parameter has the following format:
"<Root name>" + TAB + ["<Name of 1st node>" + TAB + ...
["<Name of 2nd node>" + TAB + [...]]]"<Leaf name>" A WLanguage error occurs if this parameter does not correspond to an existing branch. If this parameter is not specified, the status of the node found in the current row is returned. Observaciones A collapsed or expanded node can be visible or not The status returned corresponds to the internal status of the element. An expanded element is not necessarily visible because one of its parents may be collapsed. For example: If the node "Recipes" + TAB + "Desserts" is rolled up, the node "Recipes" + TAB + "Desserts" + TAB + "Ice cream" can be rolled up or unrolled. Selection bar TableItemStatus does not change the position of the selection bar. Runtime speed The runtime speed of syntax 1 is faster than the runtime speed of syntax 2.
