Description

x is the X coordinate, in pixels, where the mouse button was pressed referenced against the origin (0, 0) of the TOCControl (the top left hand corner).

y is the Y coordinate, in pixels, where the mouse button was pressed referenced against the origin (0, 0) of the TOCControl (the top left hand corner).

ItemType specifies an enumeration indicating the type of item (none, map, layer, heading or legend class).

Map specifies an IMap object.

Layer specifies an ILayer object.

Unk specifies an ILegendGroup object.

Data specifies a long indicating the index of the legend class within the legend group. Use this index in conjunction with the legend group to obtain a particular legend class. An index of -1 refers to the heading if it is present.

IMap map = null; 
ILayer layer = null; 
Object other = null;
Object index = null;
esriTOCControlItem item = esriTOCControlItem.esriTOCControlItemNone;

AxTOCControl1.HitTest(e.x, e.y, item, map, layer, other, index);

Dim pMap As Map = Nothing
Dim pLayer As ILayer = Nothing
Dim pOther As Object = Nothing
Dim pItem As esriTOCControlItem
Dim pIndex As Object = Nothing

AxTOCControl1.HitTest(e.x, e.y, pItem, pMap, pLayer, pOther, pIndex)
