Hello,
I've been breaking my head over this one. probably due to lack of experience.
I have two memory tables filled by programming. I want to make a drag and drop between them so taht when i drop a line of table_1 in table_2 i can start a procedure that does some things. I want to give taht procedure the Id i have in table_1 as a parameter.
Since the two tables are totaly different from each other i must use programmed drag and drop.
I read the complete helpfile on the subject. Done word for word what it says, but nothing works. The target table does not accept my drop.
I can't find a useful example with a similar situation, only DnD between listboxes, no tables.
Can anyone help me ?
Thanks a lot in advance,
Wilfried |

Did you check the window Window_DND provided with windev?
It's between treeviews (source) and tables (target) but it can give you some hints on how to program drag/drop |

Hi.
I had some difficulties the first time too.
This is my actual code:
Table 1 dndDragOver process
nHoveredRow is int =gproc_HoveredRow(MySelf..Name) IF nHoveredRow < 0 THEN DnDCursor(dndNone) RETURN END IF TABLE_Facturas..NewLine THEN DnDCursor(dndNone) RETURN END IF nHoveredRow = TABLE_Facturas THEN DnDCursor(dndNone) RETURN END DnDCursor(dndCopy) Table 1 dndDrop process
IF _DND.SourceControl <> TABLE_facturas_lineas..Name THEN RETURN nHoveredRow is int =gproc_HoveredRow(MySelf..Name) IF YesNo("yess = Copyy, Noo = Movee") THEN FOR EACH SELECTED ROW OF TABLE_facturas_lineas HReadSeekFirst( QRY_table_facturas_lineas,facturas_lineasID,TABLE_facturas_lineas.COL_facturas_lineasID) QRY_table_facturas_lineas.IDfactura = TABLE_Facturas[nHoveredRow].COL_IdFactura HAdd( QRY_table_facturas_lineas) END ELSE FOR EACH SELECTED ROW OF TABLE_facturas_lineas TABLE_facturas_lineas.COL_IDfactura = TABLE_Facturas[nHoveredRow].COL_IdFactura TableSave(TABLE_facturas_lineas) END END TableDisplay(TABLE_facturas_lineas)
Table 2, the one where i click to drag the rows out of it have no code at all.
Drag and Drop "Is Target" and "Is Source" options are disabled on both tables.
Regards,
José Antonio. |
