How to get position of a ring in a tree control?

[tstanley]

Ok, this is probably a stupid question, but how does one get the position of a ring inside of a tree control?  I have a tree with two columns, with rings in the second column.  I can set the position using SetTreeCellRingValueFromIndex(), but how does one get the position after the user has modified the control?  I found the functions GetTreeCellRingIndexFromValue() and GetTreeCellRingValueFromIndex() but I haven't found a way to get either the Index or the Value of the ring (what I'm looking for is the index, but if I can obtain the value I can go from there).  Thanks in advance!

Hi,

You can use GetTableCellVal function to get the value of the ring.

There is not special "ring" function for that. Maybe that's what you were searching for 😉

From the value you can get to the index using the functions you are already aware of.

Hope this helps,

Hi,

Thanks for the reply.  I believe that function is for a Table control.  I tried it on the Tree control anyway, and I get an error of -10 "The control is not the type expected by the function.".

I'm still stumped on this.  I tried looking through the examples, hoping to find a Tree example that uses rings, but none of them do.  Seems like I must be missing something obvious.

You can get the value of the tree cell by GetTreeCellAttribute(ATTR_LABEL_TEXT). Then, as you noted, you can use GetTreeCellRingIndexFromValue() to get the index.

Hope this helps.

Hi,

Using ATTR_LABEL_TEXT works.  I guess thinking of the ring value as the label text didn't seem intuitive for me.  Thanks!
