GridHitTest Method

  • Artigo

Returns, as output parameters, the components of a grid control corresponding to specified horizontal (X) and vertical (Y) coordinates.

Grid.GridHitTest(nXCoord_In, nYCoord_In
   [, nWhere_Out [, nRelRow_Out [, nRelCol_Out [, nView_Out]]]])

Parameters

  • nXCoord_In
    Specifies the horizontal (X) position in pixels within the form containing the grid.
  • nYCoord_In
    Specifies the vertical (Y) position in pixels within the form containing the grid.
  • nWhere_Out
    An output parameter that contains a value corresponding to the grid component at the position specified with nXCoord_In and nYCoord_In. The following table lists the values for @nWhere_Out and the corresponding grid component.
    @nWhere_Out Grid component
    0 A grid component that cannot be determined.
    1 Column header.
    2 Between column headers.
    3 Cell.
    4 Reserved.
    5 SplitBar.
    6 Record deletion marker.
    7 Reserved
    8 Reserved.
    9 Reserved.
    10 Reserved.
    11 Box in upper left corner.
    12 Record marker.
    13 Column header sizing area.
    14 Row sizing area.
    15 Reserved.
    16 Horizontal scrollbar.
    17 Vertical scrollbar.
  • nRelRow_Out
    An output parameter containing the relative grid row at the specified point.
  • nRelCol_Out
    An output parameter containing the relative grid column at the specified point.
  • nView_Out
    An output parameter containing a value corresponding to the grid pane containing the specified point. If the grid is split into two panes, this parameter contains 0 if the specified point is in the left pane, and contains 1 if the specified point is in the right pane. If the grid isn't split into separate panes, this parameter contains 1.

Remarks

The GridHitTest( ) method returns true (.T.) if the specified point is within the grid; otherwise false (.F.) is returned.

The GridHitTest( ) method can be used during mouse events or OLE drop target events to determine where the mouse pointer is positioned over the grid. The nRelRow_Out and nRelCol_Out parameters can be passed to the ActivateCell( ) method to activate a specific cell in the grid.
