Help With Coding Single Link (Not In A List)

[Trenloe]

Oh - and is the GM removing the link or a player?

[dulux-oz]

After using that, if you close and re-open the window has the link gone? I'm wondering if it is a refresh issue.

Also try removing the link, closing FG and going back in and see if the link is still there?

I had a recent issue where changing the icon of a button was only refreshing if you closed FG and opened it again. JPG fixed that specific issue in 3.0.3.

Yup, tired that as well - still a no go

In the table entry that Nickademus references the linkfield (resultlink) is hidden if there is no link to it (setVisible(false)) and set to visible if there is link data, this is done via the updateDisplay function. Perhaps you could do something like that? Of course, the main issue here is that there is no obvious link icon to drag a link to.

	<windowclass name="table_result">
		<margins control="0,0,0,2" />
		<script>
			function onInit()
				registerMenuItem(Interface.getString("table_menu_linkdelete"), "erase", 8);
				updateDisplay();
			end
			
			function onMenuSelection(selection)
				if selection == 8 then
					resultlink.setValue();
				end
			end
			
			function updateDisplay()
				local bLink = not resultlink.isEmpty();
				resultlink.setVisible(bLink);
			end
			
			function onDrop(x, y, draginfo)
				if draginfo.isType("shortcut") then
					resultlink.setValue(draginfo.getShortcutData());
					return true;
				end
			end
		</script>
		<sheetdata>
			<genericcontrol name="leftanchor">
				<bounds>0,2,0,20</bounds>
				<disabled />
			</genericcontrol>
			<genericcontrol name="base">
				<anchored position="over" />
				<script>
					function onDrop(x, y, draginfo)
						return window.onDrop(x, y, draginfo);
					end
				</script>
			</genericcontrol>
			<link_tableresult name="resultlink">
				<anchored>
					<top offset="2" />
					<left parent="leftanchor" anchor="right" relation="relative" offset="5" />
				</anchored>
				<invisible />
				<script>
					function onValueChanged()
						window.updateDisplay();
					end
					function onDrop(x, y, draginfo)
						return window.onDrop(x, y, draginfo);
					end
				</script>
			</link_tableresult>

I just tried it on my machine, by modifying the table record to test setValue() specifically. It's working as expected.

Looking at your code again, I think the problem is that you do not have "return true" at the end of your onDrop function. What I think is happening is that the value is actually being cleared in your onDrop event handler. However, since there is no return value, FG continues to process the drop event normally, which means that the link gets set again by the built-in windowreferencefield code.

That was it - thanks Moon.

As always, its the little things that trip you up the most
