Description
This function allows you to DRAGINFO information structure.
Access the drag information.
DLL
PMDRAG.DLL
os2.h
Syntax
#define INCL_WINSTDDRAG #include <os2.h> PDRAGINFO pdinfo; /* Pointer to the DRAGINFO structure. */ BOOL rc; /* Success indicator. */ rc = DrgAccessDraginfo(pdinfo);
Parameters
pdinfo (PDRAGINFO) - input
- Pointer to the DRAGINFO structure.
rc (BOOL) - returns
- Success indicator.
TRUE Successful completion. FALSE Error occurred.
Returns
rc (BOOL) - returns
Success indicator.
TRUE Successful completion.
FALSE Error occurred.
Remarks
This function is used by the target of a drag operation to access a DRAGINFO structure. The address of the structure is passed in a drag message (DM_DRAGOVER, DM_DROP, or DM_DROPHELP).
To release the structure, use the DrgFreeDraginfo function.
Example Code
This example uses the DrgAccessDraginfo function to make an existing drag information structure (created by the DrgAllocDraginfo function) available.
#define INCL_WINSTDDRAG /* Direct Manipulation (Drag) Functions */ #include <os2.h> BOOL fSuccess; /* Indicate success or failure */ DRAGINFO Draginfo; /* Drag-information structure */ fSuccess = DrgAccessDraginfo(&Draginfo);
