The LV_HITTESTINFO structure contains information about a hit test.
typedef struct _LV_HITTESTINFO { POINT pt; UINT flags; int iItem; } LV_HITTESTINFO;
Value |
Meaning |
LVHT_ABOVE |
The position is above the client area of the control. |
LVHT_BELOW |
The position is below the client area of the control. |
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 ¾ for example, if the position is above and to the left of the client area.
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.
This structure is used with the LVM_HITTEST message.
