Stored procedures
Finds the index of an element in a TreeMap control from the element path. This path was specified in TreeMapAdd.
Example
// Le champ TMAP_Vin est rempli à partir d'un champ Table. 
// Recherche de l'élément correspondant à l'élément sélectionné dans le champ Table
CheminSélection is string
CheminSélection = COL_Typevin[TABLE_VIN] + "\" + COL_Proprietaire[TABLE_VIN]
IndiceElement = TreeMapSeek(TMAP_Vin, CheminSélection)
// Sélection de l'élément dans le champ TreeMap
IF IndiceElement <> - 1 THEN
	TMAP_Vin = IndiceElement
END
Syntax
<Result> = TreeMapSeek(<TreeMap control> , <Element path> [, <Start index>])
<Result>: Integer
  • Index of the element found,
  • -1 if no element corresponds to the search.
Remark: The element found can be manipulated directly using its index. You can for example modify the properties of this element or select it in the TreeMap control.
<TreeMap control>: Control name
Name of the TreeMap control used.
If this parameter corresponds to an empty string (""), the control used will be the TreeMap control to which the current event belongs.
<Element path>: Character string
Path and caption of the sought element. This path must be identical to the one used when the element was added into the TreeMap control by TreeMapAdd.
The separator of different path elements can be:
  • the "\" character. For example: "MyDirectory\MyFile".
  • the "TAB" character. For example: "Desserts "+TAB+"Crème brulée".
<Start index>: Optional integer
Index of the element from which the search will be performed. If this parameter is not specified, the search is performed in the entire TreeMap control. This parameter is used to find all the occurrences of a path.
