- Moving an element onto itself
- Duplicates
- Priority order for the sort
<TreeView>.MoveItem (Function) In french: <Arbre>.DéplaceElément Moves an element (leaf or node) in a TreeView control. All branches issued from this element are also moved. Example of TreeView control:
Res = TREE_TVRecipe.MoveItem(...
"Recipes" + TAB + "Desserts" + TAB + "Fruit salad", ...
"Recipes" + TAB + "Starters", tvFirst)
Syntax
<Result> = <TreeView control>.MoveItem(<Source element> , <Destination element> [, <Sort mode>])
<Result>: Boolean - True if the element was moved,
- False otherwise.
<TreeView control>: Control name Name of the TreeView control to be used. <Source element>: Character string Path of element (leaf or node) to move. This element and all the branches issued from this element will be moved. This parameter has the following format:
"<Root name>" + TAB + ["<Name of 1st node>" + TAB + ... ["<Name of 2nd node>" + TAB + [...]]]"<Leaf name>" If there are two elements with the same name in the path, you can add the IDs of the elements (after their names using TreeID). <Destination element>: Character string Path of element (leaf or node) corresponding to the new "parent" node of the moved element. This element must exist. This parameter:- has the following format:
"<Root name>" + TAB + ["<Name of 1st node>" + TAB + ... ["<Name of 2nd node>" + TAB + [...]]]"<Leaf name>" If there are two elements with the same name in the path, you can add the IDs of the elements (after their names using TreeID). - corresponds to the NULL constant if the "parent" node is the root of the TreeView control.
<Sort mode>: Optional constant (or combination of constants) Position of the moved element in relation to the "child" elements of the destination node. | | tvAcceptDuplicate | The duplicates are accepted (two elements on the same level can have the same name). The moved element is inserted in alphabetical order, among the elements of the same level. | tvAlphaSort (Default value) | The moved element is sorted in alphabetical order, among the elements of the same level. | tvFirst | The element is moved to the first position of the level. | tvLast | The element is moved to the last position of the level. |
Remarks Moving an element onto itself An element cannot be moved onto itself or onto one of its children. In this case, <TreeView>.MoveItem returns False and the element is not moved. Duplicates Two cases may occur if the <Destination element> already contains a child with the same name as the <Source element>: - If the duplicates are accepted (tvAcceptDuplicate constant), the move is performed as usual. <TreeView>.MoveItem returns True.
- If duplicates are not accepted, <TreeView>.MoveItem returns False. The element is not moved.
If the <Source element> contains duplicates with identifiers, these duplicates are moved and keep the same identifier. Priority order for the sort The priority order of parameters for the add mode is as follows: For example, in tvFirst + tvLast + tvAlphaSort, only the tvFirst constant is taken into account and run.
