TableInfoXY (Function) In french: TableInfoXY Returns for a given position in a Table or TreeView Table control (coordinates of a control point): - the name of the column displayed for the specified position.
- the index of the row or column for the specified position.
ResInfo = TableInfoXY(TABLE_TableProduit, tiLineNumber, 50, 100)
Syntax
<Result> = TableInfoXY(<Table control> , <Type of information> , <X> , <Y>)
<Result>: String, integer or boolean - Requested information.
- An empty string ("") if there is no column name.
- -1 if there is no column index or row number, or if the specified position corresponds to an empty row or column.
<Table control>: Control name Name of the Table or TreeView Table control to be used.
If this parameter corresponds to an empty string (""), the control to which the current event belongs will be used. <Type of information>: Integer constant Type of information requested: | | | tiColName | Column name. | | tiColNumber | Column creation index. | | tiLineNumber | Row number. | | tiOnButtonCollapseExpand | "+/-" buttons to expand/collapse a row. In this case, <Result> is set to True (1). This constant is only available for TreeView Table controls. | | tiOriginScreen | The coordinates to be analyzed are relative to the screen. Reminder: By default, the coordinates to be analyzed are given in relation to the Table field: the point (0,0) corresponds to line 1, column 1 of the manipulated Table field (with the scrollbars at the origin). This constant cannot be used on its own. |
<X>: Integer X-coordinate (in pixels) to be analyzed. This coordinate is given in relation to the control (if the tiOriginScreen constant is not specified). <Y>: Integer Y-coordinate (in pixels) to be analyzed. This coordinate is given in relation to the control (if the tiOriginScreen constant is not specified). Remarks Use conditions TableInfoXY can be used on: - Table or TreeView Table controls based on a data file.
- Table or TreeView Table controls populated programmatically.
- single-selection or multi-selection controls.
- the function doesn't return any result if the Table control is empty.
The different types of column indexes There are 2 types of indexes for columns: - Visible position index: column index when the window is executed.
- Creation index: column index when the table is created in the window editor.
These indexes change if the user moves the columns. Additionally, if the horizontal scrollbar is used, TableInfoXY takes this change 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 "Select a row" event 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. Business / UI classification: UI Code
