How can I get the tableview index from a control in the row

Getting Started Newbie Questions

Hi,

I have a button in each row of a tableView. When the user completes a taks, he/she clicks on the buttons.

For onRowTouch, the listening function  can use the target.index

Like so

local function RowTouch(e)  local row = e.target  print(row.index) end

and will print out the index (ignore phases for now).

When I am rendering my tableview, I am adding the button to each row rendered -that is not a category.

Like so.

if (row.isCategory == false) then    local btncheck = widget.newButton({    label = "check",    left = display.contentWidth-80,    width = 75,    onEvent = btncheck\_clicked    })       row:insert(btncheck) end

so  - in my function btncheck_clicked(), how do I get the current row?

Thanks.

This is not a direct answer, but if you want to dig into the guts of widgets you can look at the code here:

I would put this inside row render and do btncheck.index = row.id( I am pretty (99%) sure that is how you get row number). That is what I did in my game.

Hi RoamingGamer,

I appreciate the feedback, and have looked through the documents.

Unfortunately, what I am looking for is a way to capture the row index (or any information I have saved via Row:insert()) with a control on the row itself.

Something very similar to the onDisclosure button in IOS.

I am surprised that there is not a simple way to know which row the control is on.

I will keep digging, but again, appreciate the help.

Thanks.

Hi Scottrules44,

That worked!

Thanks.

In case anyone needs this in the future.

In the onRender, I set the buttons ID to the row.index

row.btn = widget.newButton({ id = row.index, width = 60, onEvent = showclicked, }) row:insert(row.btn)

in the event function

​local function showclicked(e)     print(e.target.id ) end

ps - codes a little different from the original post.
