I have added a dragsource to my tablelist (6.16 and 6.21) to be able to drag the selection elsewhere in my application.
But now I can no longer drag out a selection of multiple rows.
The documentation says that setting dragsource to true should reset the selection on mouse up (DRAG SOURCE SUPPORT FOR GLOBAL DRAG & DROP)
The following code shows the problem
tablelist::tablelist .t -width 40 -stretch all -columns {0 Name left 0 Description left} -selectmode extended -customdragsource true -activestyle none
pack .t -fill both -expand y
.t insert end [list Part1 "This is part 1"]
.t insert end [list Part2 "This is part 2"]
.t insert end [list Part3 "This is part 3"]
.t insert end [list Part4 "This is part 4"]
Any mouse press (left) just moves the selection.
Is there a missing option ?

This is the expected and documented behavior, similar to what you can
see, e.g, in a file manager. To extend the selection, you will have to
press Shift or Control before clicking.

OK, I reread (again) the section and understand better . I was mixing in with the drag select in explorer which superposes a drag rectangle over the entries.
Thanks for the quick reply
