The HD_HITTESTINFO structure contains information about a hit test.
typedef struct _HD_HITTESTINFO {
POINT pt;
UINT flags;
int iItem;
} HD_HITTESTINFO;
Members
pt

flags
Variable that receives information about the results of a hit test. This
member can be one or more of the following values:
Value
| Meaning
| HHT_NOWHERE
| The point is inside the bounding rectangle of the header control but is not
over a header item.
| HHT_ONDIVIDER
| The point is on the divider between two header items.
| HHT_ONDIVOPEN
| The point is on the divider of an item that has a width of zero. Dragging the
divider reveals the item instead of resizing the item to the left of the
divider.
| HHT_ONHEADER
| The point is inside the bounding rectangle of the header control.
| HHT_TOLEFT
| The point is to the left of the bounding rectangle of the header control.
| HHT_TORIGHT
| The point is to the right of the bounding rectangle of the header control.
|
Two of these values can be combined, such as when the position is above and to
the left of the client area.
iItem
Receives the index of item at point, if any.
Remarks
This structure is used with the HDM_HITTEST message.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
