Purpose |
To provide a call-back that is called when a file or a group of files is dragged and dropped onto the window. |
|
Syntax |
winio@('%dr',cb_func) |
|
Description |
Use a call to CLEARWIN_STRING@('DROPPED_FILE') within the call-back in order to get the name of the file that has been dropped. If there is more than one file then the call-back function is called for each in turn. You can use CLEARWIN_INFO@('DROPPED_COUNT') to get the number of files that have been dropped (call this n say) and then use CLEARWIN_INFO@('DROPPED_CURRENT') to get the index of the current file in the range from 1 to n. |
|
Notes |
A negative or zero return value in the call-back function for %dr cannot be used in the normal way to close the parent window. |
