TableView - how to reRender all visible rows immediately?

sunmils · November 17, 2012, 1:22pm

how can I reRender the whole tableView without user interaction? I’ve tried

list.content.rows[i].reRender = true

but that only works after the list was moved a bit. There must be an easy way out, is’t it? thanks! [import]uid: 53732 topic_id: 33094 reply_id: 333094[/import]

Do a getListPosition() call, it will return the y value and then call the scrollToY() call and pass it the y. That will force a redraw of the table.

You will need to get documentation from one of the later daily builds to see the docs for these two calls. [import]uid: 19626 topic_id: 33094 reply_id: 131468[/import]

Unfortunately it doesn’t work. I tried with the current build. getListPosition() is not a valid function. I tried

[lua]list:scrollToY(list:getContentPosition())[/lua]

instead. This worked with no error, but without redraw of the tableview

any ideas? [import]uid: 53732 topic_id: 33094 reply_id: 132399[/import]

Nothing new on this topic? May I do something wrong? Could you please post a little code snippet which makes clear your suggestion?

thanks,

try this, it worked for me

local y = list:getContentPosition() list:scrollToY(y,0)

Didn’t work for me either. Am I correct in thinking this only works for lists, not tableViews? This is my code:

local function getfilelistener(event) &nbsp;&nbsp;&nbsp;&nbsp;if (event.isError) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print( "Network error - download failed" ) &nbsp;&nbsp;&nbsp;&nbsp;elseif (event.phase == "began") then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print( "Progress Phase: began" ) &nbsp;&nbsp;&nbsp;&nbsp;elseif (event.phase == "ended") then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if event.response.filename then&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print( "loaded image "..event.response.filename ) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;--force re-render visible &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;local y2 = tableView:getContentPosition() &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print("pos:"..y2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tableView:scrollToY({y=y2,time=0}) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;end &nbsp;&nbsp;&nbsp;&nbsp;end end &nbsp;

I’m currently looking at passing the onRowRender event as parameter to the network listener and call onRowRender(rowEvent) when phase==“ended”. Would that be correct?
