scrollView:takeFocus() not working in latest build

Solar2D Widgets

The takeFocus method is not working for me since updating to the latest daily build. Is anyone else running in to this issue?

Error:
“attempt to call method ‘takeFocus’ (a nil value)”

Code Snippet:

[code]
elseif event.phase == “moved” then – Check if you moved your finger while touching

local dx = math.abs( event.x - event.xStart ) – Get the x-transition of the touch-input
local dy = math.abs( event.y - event.yStart ) – Get the y-transition of the touch-input

if dx > 5 or dy > 5 then
scrollView:takeFocus( event ) – If the x- or y-transition is more than 5 put the focus to your scrollview
end

I think Danny from Corona is on this like a fat kid on cake. There are a few threads going on about this topic. I use the exact same thing in my game in the app store, so I’m in need of a quick fix as well. I found this in the comments section for the widgets 2.0 blog. I don’t know who wrote it, so sorry if I step on any toes.

[lua]
display.getCurrentStage():setFocus( nil )
target.isFocus = false

– set event.target to scrollView and start back at “began” phase
event.target = self._scrollView._view
event.phase = “began”
self._scrollView._view.touch( self._scrollView._view, event )

Hi Sxc,

 

I’ve tried typing in the code, but i get an error with ._scrollView or ._view, does the above mentioned still work for you?  I’m using Build 2013.1053.

Any help would be appreciated!

 

Thanks

Got it. Insteading of “._scrollView._view”, “._view” after my scrollview widget worked for me.  Thanks anyways.

I’m having the same problem.

 

Error message:

Attempt to call method ‘takeFocus’ (a nil value)

 

I’m guessing this is a bug in the current daily build.

Please could you explain how you solved this?

Are you defining your own takeFocus function?

I tried sXc’s method, instead of using takeFocus which is currently not available for widget 2.0. Upon event.phase == "moved, i set focus to nil, then force my scrollview widget ( “scroller” in my case ) and instruct it to take control and do it’s thing.  Hope that helps.

 

 

    if event.phase == “moved” then

        display.getCurrentStage():setFocus( nil )

        event.target = scroller._view

        event.phase = “began”

        scroller._view.touch( scroller._view, event )

        --scroller:takeFocus( event )

Benny, that solution works like a charm, that you!
