DragData.setDescription() Help Required

[dulux-oz]

Hi Guys,

Could someone please provide an example of setting the Description (or other elements) of a Dragdata object for a Shortcut item (ie when to call the dragdata.setDescription() function) - I need to set a couple of values so that when I drag an item from a list and drop it onto another list certain values are checked. My onDrop() Code is as follows:

function onDrop(nXPos,nYPos,oDragData)
	if oDragData.getType() == "shortcut" and
			oDragData.getShortcutData() == "my_value" then
		local oChildNode = DB.createChild(getDatabaseNode());
		DB.setValue(oChildNode,"name","string",oDragData.getDescription());
		DB.setValue(oChildNode,"shortcut","windowreference",oDragData.getShortcutData());
	else
		return true;
	end
end

Thanks guys

Have a look at the definition of the windowreferencecontrol (or linkfield template) for the objects your dragging, you can auto-set the description of the link (when dragged) by adding the following tag to the windowreferencecontrol/linkfield definition.

<description control=[name of field/control]>

e.g.

<windowclass name="reference_indexitem">
 <margins control="0,0,0,2" />
 <sheetdata>
  <linkfield name="listlink">
  <bounds>5,2,20,20</bounds>
  <description control="name" />
  <readonly />
  </linkfield>
  <string_list_link name="name">
  <bounds>25,2,-1,20</bounds>
  <linktarget>listlink</linktarget>
  </string_list_link>
 </sheetdata>
</windowclass>

In the example above the description of the linkfield is set to the value of the name control. See the developer reference guide for more information on windowreferencecontrol.

Thanks Zeus - missed it in my read-through

What the Developer Documentation needs is a really good search function

Cheers
