This structure has been extended to accommodate subitem hit-testing. The LVHITTESTINFO structure contains information about a hit test. It is used in association with the LVM_HITTEST and LVM_SUBITEMHITTEST messages and their related macros.
Position to hit test, in client coordinates.
Receives information about the results of a hit test. It can be one or more of the following values.
The position is above the control's client area.
The position is below the control's client area.
The position is inside the list-view control's client window, but it is not over a list item.
The position is over a list-view item's icon.
The position is over a list-view item's text.
The position is over the state image of a list-view item.
The position is to the left of the list-view control's client area.
The position is to the right of the list-view control's client area.
You can use LVHT_ABOVE, LVHT_BELOW, LVHT_TOLEFT, and LVHT_TORIGHT to determine whether to scroll the contents of a list-view control. Two of these values may be combined. For example, if the position is above and to the left of the client area, you could use both LVHT_ABOVE and LVHT_TO LEFT.
You can test for LVHT_ONITEM to determine whether a specified position is over a list-view item. This value is a bitwise-OR operation on LVHT_ONITEMICON, LVHT_ONITEMLABEL, and LVHT_ONITEMSTATEICON.
Receives the index of the matching item. Or if hit-testing a subitem, this value represents the subitem's parent item.
Receives the index of the matching subitem. When hit-testing an item, this member will be zero.
