Detect Drag&Drop

Hi All,

I have a memorytable with automatic DnD enabled. The table is source and target so users can drag rows of the table to a different row. If the row order of the table has been changed, it's contents should be saved. How can I detect that the row order has changed by means of drag and drop?

Best regards,
Piet

Hi Piet,

(This is french):

TableInfoXY(_DND.ChampCible,tiNumLigne,_DND.SourisPosX,_DND.SourisPosY)

Use this code in the procedure managing the drop event. This will give you the line where the drop occurs. Then compare the actually selected row number with that new number.

Best regards.

Hi Alexandre,

Thanks for your reply, but I want to avoid programmed DnD. Just want to set a flag if a change of order occurred and save the whole table.

Piet

Hi,

Does anyone know if it's possible to detect drag or drop using Event?

Piet

Hi Piet...

considering that everything in windows works via events, I would say yes...

To find out what event to trap, just set an event on ALL (see event help for syntax) on the table handle... In this event procedure, trace the event number and wparam, lparam...

Then do a drag and drop and read directly the vent number you need and perhaps even some interesting informations in wparam, lparam (line number?)

Thanks, Fabrice.

I already solved it. It appears that automatic and programmed DnD can be active simultaneously. So I did a DnDEvent("Drop_SetFlag",TABLE_PlayList,dndDrop).
That works while automatic Dnd still works too.
