Dragsource, droptarget and valreps

Author: i.sharp@pcisystems.co.uk (Iain Sharp)

I am trying to create a drag and drop interface in my app.  I set the dragsource valrep to ITEM=^glyph_a and the dragtarget valrep to ITEM=^glyph_a;=^glyph_b According to the documentation, using the Label property of the dragtarget allows me to use the second subfield in the data to specify a label.  However, if I try to do this I get a valrep error.  0119 - Error on field FIELD - Illegal valrep value ITEM;Label The label does change, which indicates that it has found the subfield. How do I configure the valrep not to error? (I tried setting the valrep row to ITEM;* but this created a new row in the valrep of *.)

All of that works for me as well, however, when I try and change occurrence, (The droptarget (and dragsource) are in multi occurrence entities) the validation fires and I can't leave the occurrence because bad valrep.

Hmm. I have tried it with multiple occurrences now and I still don't have a problem. But reading your original post again I see what might be the problem... The label goes in the value of the field, not in the valrep. The value of the field can be ITEM;label and the valrep for that needs to be ITEM=^GLYPH

Checking the reported issues shows Issue 19664 which seems similar yet different in that it talks about trying to validate the second subfield. The workaround is to turn $validation to limited for the system as a whole, I obviously don't want to do that.

I haven't done this for a very long time, so I tried a few things. This works for me:   I have painted a DragSource widget with an associated label: DataType: Image (any source) Interface: C* Initial Value: ITEM;Theo   (; is GOLD ; ) In the Widget Properties  I check the Source checkbox, and the Dynamic Label checkbox In the valrep I put Value ITEM and Representation ^I_OK   I have painted a DropTarget widget with an associated label: DataType: Image (any source) Interface: C* Initial Value: no initial value In the Widget Properties  I check the Target checkbox, and the Dynamic Label checkbox In the valrep I put in two lines Value blank and Representation ^FIND (blank is empty, no value, nothing) Value * and Representation ^I_OK (* is GOLD *)   If I now compile and run I see in my Source the OK glyph with label Theo, and in my Target the Find glyph with no label. If I now drag my source to my target, my target gets the OK glyph and the label Theo   Hope this is of use.   Theo
