<TreeView>.InfoXY (Function) In french: <Arbre>.InfoXY Returns the element of a TreeView control found at a given position. Example of TreeView control:
// -- Click on the TREE_TreeView1 control
X, Y are int
X = LoWord(CursorPos())
Y = HiWord(CursorPos())
// Find the number of the row corresponding to the click
RowClick is int
RowClick = TREE_TreeView1.InfoXY(treeLineNumber + treeOriginScreen, X, Y)
// Find the branch name
Branch is string
Branch = TREE_TreeView1.InfoXY(treeBranchName + treeOriginScreen, X, Y)
Trace("You've clicked the branch " + ...
Branch + "(row #" + RowClick + ")")
Syntax
<Result> = <TreeView control>.InfoXY(<Type of information> , <X> , <Y>)
<Result>: Character string, integer or Integer constant Requested information:- Number of the row at specified point, -1 if there is no row.
- Name of the branch at specified point, empty string ("") if there is no branch.
- Type of hovered area. This type corresponds to one of the following constants:
| | | tizButton | "+ / -" button next to the caption of the TreeView control element. | | tizCaption | Element caption. | | tizCheckmark | Checkmark of element. | | tizImage | Image displayed in front of the element caption. | | tizLeft | Space found on the left of element caption. | | tizOut | Space below the elements of the TreeView control. | | tizRight | Space found on the right of element caption. |
<TreeView control>: Control name Name of the TreeView control to be used. <Type of information>: Constant or combination of constants Requested type of information: | | | treeBranchID | Identifier of element found at (X, Y). | | treeBranchName | Name of element found at (X, Y). | | treeLineNumber | Number of the row found at (X, Y). | | treeOriginScreen | If this option is specified, the origin of specified coordinates corresponds to the screen (and not the TreeView control).
This constant cannot be used on its own. | | treeZone | Type of hovered area |
<X>: Integer X-coordinate (in pixels) to be analyzed. This coordinate is given in relation to the TreeView control (if the treeOriginScreen constant is not specified). <Y>: Integer Y-coordinate (in pixels) to be analyzed. This coordinate is given in relation to the TreeView control (if the treeOriginScreen constant is not specified). Remarks Row number at specified point If the treeLineNumber constant is used, <TreeView>.InfoXY returns the number of the row for the specified point. This row number is an "instantaneous" row number, it takes into account all the elements expanded above the row. This row can be handled by the following syntax:
<TreeView control> [<Number of row to handle>]
