The _ACCEPTFILEDROP statement prepares a program window to receive files dropped from Windows Explorer in a drag/drop operation.
Syntax
- _ACCEPTFILEDROP [{ON|OFF}]
Description
- Calling the statement with no parameters turns drag/dropping ON.
- To know when files have been dropped into your program's window, check that _TOTALDROPPEDFILES is greater than 0.
- Use _DROPPEDFILE to read the list, either sequentially or by index.
- If using _DROPPEDFILE with an index, you must call _FINISHDROP after you finish working with the list.
- Keyword not supported in Linux or macOS versions
Availability
- Version 1.3 and up.
Examples
Example: Accepting files dragged from a folder and processing the list received sequentially.
SCREEN _NEWIMAGE(128, 25, 0) _ACCEPTFILEDROP 'enables drag/drop functionality PRINT "Drag files from a folder and drop them in this window..." DO IF _TOTALDROPPEDFILES THEN FOR i = 1 TO _TOTALDROPPEDFILES a$ = _DROPPEDFILE 'reads the list sequentially; when the result is empty ("") it means the list is over COLOR 15 PRINT i, IF _FILEEXISTS(a$) THEN COLOR 2: PRINT "file", ELSE IF _DIREXISTS(a$) THEN COLOR 3: PRINT "folder", ELSE COLOR 4: PRINT "not found", 'highly unlikely, but who knows? END IF END IF COLOR 15 PRINT a$ NEXT END IF _LIMIT 30 LOOP |
