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.
Syntax
typedef struct _LVHITTESTINFO {
POINT pt;
UINT flags;
int iItem;
int iSubItem;
} LVHITTESTINFO;
Members
- pt
Position to hit test, in client coordinates.
flags
Receives information about the results of a hit test. It can be one or more of the following values.Value Description LVHT_ABOVE
The position is above the control's client area.
LVHT_BELOW
The position is below the control's client area.
LVHT_NOWHERE
The position is inside the list-view control's client window, but it is not over a list item.
LVHT_ONITEMICON
The position is over a list-view item's icon.
LVHT_ONITEMLABEL
The position is over a list-view item's text.
LVHT_ONITEMSTATEICON
The position is over the state image of a list-view item.
LVHT_TOLEFT
The position is to the left of the list-view control's client area.
LVHT_TORIGHT
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.
- iItem
Receives the index of the matching item. Or if hit-testing a subitem, this value represents the subitem's parent item.
- iSubItem
Receives the index of the matching subitem. When hit-testing an item, this member will be zero.
Remarks
This structure supersedes the LV_HITTESTINFO structure.
