Re: Drag n drop (between processes)

This is a problem is of my own making, as the code for drag_n_drop was moved from the host system to a component. As a result in the case of 2 or more allowed source tables, a process variable which contained a pointer to the dropped record's source table was no longer accessible. right now

Re: Drag n drop (between processes)

I throw the data i want dropped into an object for dragndrop. Then when i drop I know what iam getting as i include the table and record numbers. Where i dragged it from(process,form,object) are also included. Made my listbox drag an drop so much easier to handle and very generic. Sent from my

Re: Drag n drop (between processes)

Chip, This is how we manage dragging form a listbox in one process to a listbox in another process: 1. In the source listbox: *Case of* *:* (*Form event*=On Begin Drag Over) *RESOLVE POINTER*(*Self*;tSourceObjectName;$Table;$field) *ARRAY LONGINT*($aiItemsSelected;0) $lElementPos:=*Selected

Re: Drag n drop (between processes)

Chip: Here’s some ALP code that uses that command - it might give you some ideas… *Case of* *:* ($formEvent_L=On Drop) *Case of* *:* ($currentObjectName_T="Lock_CustomerName”) *C_BLOB*($blob_X) *GET PASTEBOARD DATA*("net.e-node.alp.object";$blob_X) *If* (OK=1) *C_LONGINT*($eList)

Re: Drag n drop (between processes)

Chip: Check out the docs for “Managing Pasteboards”. I’ve used this feature only with ALP but ALP uses the same drag and drop events that 4D does so there will be some overlap. 4 bytes could well be a longint representing the process ID where the drag was initiated - that’s a WAG. The bigger

Drag n drop (between processes)

I am dragging and dropping 1 or more records from 1 process onto a listbox in a second process. I see that I can use the pasteboard to mange the data during this action. However(dragging 1 record) I am looking at the data types returned by GET PASTEBOARD DATA TYPE com.4d.private.pid &

Re: Drag n drop between processes

Hello, The 510 bytes data does not contain anything useful for you. You need to append data yourself at the drag source (append data to pasteboard), Which can be an array of record numbers/primary keys (variable to blob), A set (boolean array from set, variable to blob), Or anything that makes

Re: Drag n drop between processes - native Pasteboard only?

that it was possible to do drag n drop between processes using ONLY the pasteboard, and the native data placed there during Drag n drop. Thanks Chip On Tue, 10 Jul 2018 13:35:34 -0500, Keith Culotta via 4D_Tech wrote: > Hope this is on topic... > > During : (Form event=On Begin

Re: Drag n drop between processes

Hope this is on topic... During : (Form event=On Begin Drag Over) in the source list, I put the information about the item being dragged on the Pasteboard LOAD RECORD([Item]) C_OBJECT($obj) OB SET($obj;"$rec";Record number([Item]))

Drag n drop between processes

Context: dragging 1 (or more) records/rows from a selection listbox to another form in another process. 4D v13. I know, and can see by using GET PASTEBOARD DATA TYPE, and GET PASTEBOARD DATA that if I drag a line/record from a selection listbox to another process there is "stuff" put on the
