Example

// Optional click code on the TABLE_TABLE1 control
MyRow is int
MyColumn is string
MyRow = TABLE_TABLE1.InfoXY(tiLineNumber, MouseXPos(), MouseYPos())
MyColumn = TABLE_TABLE1.InfoXY(tiColName, MouseXPos(), MouseYPos())
Trace("You have selected the cell (" + MyColumn+", " + MyRow + ")")

// Subscript of row at point (50, 100) of "TABLE_ProductTable" control
ResInfo = TABLE_ProductTable.InfoXY(tiLineNumber, 50, 100)

Syntax

<Result> = <Table control>.InfoXY(<Type of information> , <X> , <Y>)

<Result>: Character string or integer

Requested information.
An empty string ("") if there is no column name.
-1 if there is no column subscript or no row number, or if the specified position corresponds to an empty row or to an empty column.

<Table control>: Control name

Name of Table or TreeView Table control to use.

<Type of information>: Constant

Requested type of information:
tiColName Name of column.
This constant is not available.
tiColNumber Creation subscript of column.
This constant is not available.
tiLineNumber Row number.
tiOriginScreen By default, (0,0) corresponds to row 1, column 1 of the table used (the scrollbars being located at the origin).
If the tiOriginScreen constant is combined with the previous constants, (0,0) corresponds to the origin of the screen.
This constant cannot be used on its own.

<X>: Integer

X coordinate (in pixels) to study. This coordinate is given in relation to the control (if the tiOriginScreen constant is not specified).

<Y>: Integer

Y coordinate (in pixels) to study. This coordinate is given in relation to the control (if the tiOriginScreen constant is not specified).

Remarks

Use conditions

<Table>.InfoXY can be used on:

a browsing or memory control.
a single-selection or multiselection control.
a Table or TreeView Table control.

The TreeView Table control is not available.

The different types of column subscripts

Two types of subscripts are available for the columns:

Subscript of the visible position: subscript of the column when running the window.
Creation subscript: subscript of the column when creating the table in the window editor.

These subscripts are different if the columns have been moved by the user.

Furthermore, if the horizontal scrollbar is used, <Table>.InfoXY takes this move into account.

Using MouseXPos and MouseYPos

To use MouseXPos and MouseYPos in the X and Y parameters of the function, make sure that a single mouse click will trigger the execution of the code containing this function.

For example, the event "Selecting a row" of a Table control can be started by a simple click but also by a keyboard selection. Therefore, MouseXPos and MouseYPos should not be used in this event. Use an optional event instead. In this example, use the optional event "Left button down" on aTable control.
