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 the code looks like this:
In the host
:(On Begin Drag Over)
Drag_n_Drop_Begin("Source_set";->[Source_Table])
// Source set is most often the selection set of a listbox
// source table is most often the source table for the listbox
:(On Drag Over)
$0:=Drag_n_Drop_Verify(Form Event;Allowed_to_Drop(_One or
_Many);->[allowed_table1_1...->[allowed_table_N]
// allows or fails drag over & drop
:(On Drop)
Drag_n_Drop_Verify(Form Event;Allowed_to_Drop(_One or
_Many);->[allowed_table1_1...->[allowed_table_N]
// Places dragged record(s) into current selection of allowed_Table
the Drag_n_Drop methods are all in a component.
Drag_n_Drop works as follows:
- Drag_n_Drop_Begin -- an IP set is created which holds the record(s)
being dragged.
- On Drag over, the table to which the set belongs** is compared
against the the allowed source table(s), and a long int is returned
allowing (0) or dis-allowing (-1) the drag over/Drop action.
- On Drop the IP set is used & cleared, and the dropped record(s) are
left in the current selection.
** I can do this due to code Ive written (is available as the component
'Setutl') which allows me to ask the question:
To which table does a specified set belong?
All of this works very well, when there is only 1 source table allowed.
As I have recently found, this breaks down when there are 2 or more
source tables allowed, as, Outside of the component, I do not know
which of the allowed tables the drag n drop belongs too.
After reading through the various replies, the simplest solution is to
return a pointer to source table of the drag n drop, or Nil so my new
code will look like this:
:(On Drag Over)
$0:=Drag_n_Drop_Verify(Allowed_to_Drop(_One or
_Many);->[allowed_table1_1...->[allowed_table_N])
// allows or fails drag over & drop
:(On Drop)
$Source_Table:=Drag_n_Drop_Process
if (Not(Nil($Source_Table)))
// do stuff

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)
$lElementPos:=*Selected list items*(CategoryList;$aiItemsSelected;*)
*ARRAY TEXT*($atCategoryUUIDs;*Size of array*($aiItemsSelected))
*For* ($i;1;*Size of array*($aiItemsSelected))
*GET LIST ITEM PARAMETER*(CategoryList;$aiItemsSelected{$i};"recordnumber";
$DestCategoryUUID)
$atCategoryUUIDs{$i}:=$DestCategoryUUID
*End for*
$tSource:="CategoryList"
*SET BLOB SIZE*($blob;0)
*VARIABLE TO BLOB*($tSource;$blob;*)
*VARIABLE TO BLOB*($aiItemsSelected;$blob;*)
*VARIABLE TO BLOB*($atCategoryUUIDs;$blob;*)
*CLEAR PASTEBOARD*
* APPEND DATA TO PASTEBOARD*(Text data;$blob)
*End Case*
2. In the destination listbox:
*Case of*
*:* ($event=On Drop)
*GET PASTEBOARD DATA*(Text data;$blob)
$ioffset:=0
*BLOB TO VARIABLE*($blob;$var;$ioffset)
*End Case*
*Then deal with the data according to the content of $var ("CategoryList"
in this case).*
*HTH*
*PB*

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 payload could be a BLOB of a fair amount of text or perhaps a record that was put into the clipboard when the On drag sequence started.

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 sense to you. You assign a unique “key” to that data, Which by convention looks like com.4d.whatever (UTI) but it can be any string, As long as the string is unambiguous. You can retrieve the data on the destination side using said key. > 2018/07/11 2:43、Chip Scheide via 4D_Tech <4d_tech@lists.4d.com>のメール: > what I do not know, is how do I use the data on the pasteboard. ** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **
Re: Drag n drop between processes - native Pasteboard only?
Hi Chip, You don't need to use sets. Follow Keith's scheme, but without using 4D objects (which were not available until v14.) On Begin Drag, place the record's unique key in the text pasteboard. Or if there's more than one record, store a delimited list of the record keys in the text pasteboard. On Drop, locate the "dragged" records by their keys which you placed in the pasteboard during the "On Begin Drag” event.. - Jeremy French > On Jul 10, 2018, at 3:15 PM, Chip Scheide via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > I was/am doing this through IP sets... > > ...remember someone telling me that it was possible to do drag n > drop between processes using ONLY the pasteboard... ** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **
Re: Drag n drop between processes - native Pasteboard only?
I was/am doing this through IP sets. Same idea - (to me, a bit easier and doable [v13]), copy the selected set to an IP set, access the IP set on the drop side. But I am trying to see where I can remove IP I thought I would look at NOT using sets at all. I seem to remember someone telling me 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.

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;"$rec";Record number([Item])) OB SET($obj;"$proc";Current process) OB SET($obj;"$source";"LocEdit") $text:=JSON Stringify($obj) // set your data type SET TEXT TO PASTEBOARD($text) Later on in the destination process, mouse button just up from On Begin Drag Over, the information was read back out... : (Form event=On Drop) // check here to see if it's your data type on the clipboard C_OBJECT($obj) $obj:=JSON Parse(Get text from pasteboard) $rec:=OB Get($obj;"$rec";Is longint) $proc:=OB Get($obj;"$proc";Is longint) $source:=OB Get($obj;"$source";Is text) If ($proc#Current process) & ($source="LocEdit")...
