CHeader.SetHotDividermethod
Changes the color of a divider between header items to indicate the destination of an external drag-and-drop operation.
Syntax
FUNCTION SetHotDivider (BYVAL hHeader AS HWND, BYVAL fPos AS BOOLEAN, BYVAL dwInputValue AS LONG) AS LONGParameters
| Name | Description | |
|---|---|---|
hHeader | The handle of the header control. | |
fPos | A value specifying how dw is to be interpreted. The value in this field can be one of the following: TRUE: Indicates that dw holds client coordinates of the pointer. FALSE: Indicates that dw holds a divider index value. | |
dwInputValue | The value held here is interpreted depending on the value of fPos. If fPos is TRUE, dw represents the x- and y- client coordinates of the pointer. The x-coordinate is in the low word, and the y-coordinate is in the high word. Upon receiving the message, the header control highlights the appropriate divider based on the dw coordinates. If fPos is FALSE, dwInputValue represents the integer index of the divider that will be highlighted. |
Return value
Returns the index of the divider that the control highlighted.
Description
Changes the color of a divider between header items to indicate the destination of an external drag-and-drop operation.
Remarks
A header control set to the HDS_DRAGDROP style produces this effect automatically. This message is intended to be used when the owner of the control handles drag-and-drop operations manually.
