widget:scrollView and widget:button event passing

Solar2D Daily Builds and Public Releases
#1

It seems as if the scrollView isn’t passing events properly to any buttons added to it. The press event gets triggered but not the release event. Is there a workaround for this? I am just needing button inside a scrollview and currently this seemingly simple task is a hold up. [import]uid: 58885 topic_id: 18241 reply_id: 318241[/import]

Hey Peach case #10109 I just uploaded my lua file. Maybe I should have gave some more generic code? But it’s fairly simple to reproduce and the lua file should easily show what’s going on.

I appreciate the assistance Peach! [import]uid: 58885 topic_id: 18241 reply_id: 70514[/import]

Not a problem and no, uploading the file is fine - anything that easily shows the issues is always helpful.

http://developer.anscamobile.com/forum/2011/04/16/scrollview-and-buttons

in my project, i have a whole bunch of buttons inside the scrollview and i wanted to handle and figure out which button was actually pressed.

 local buttonTouch = function(e)  
 -- ended never happens for the buttons :(  
 if e.phase == "ended" then  
 print("button touch ended "..e.target.id);  
 elseif e.phase == "began" then  
 -- began does get fired before the scrollView gets it, so save the target ref  
 activeBtn = e.target;  
 end  
 end

also, i ended up tweaking the solution from that post to make it work for my project.

I added the following to the touch handler in scrollView.lua

if math.abs(dragDistance) \< 1 then   
 Runtime:dispatchEvent( { name="scrollViewItemSelection", target=Runtime } );  
end

so that i know when the touch event ended w/o actually scrolling, which means it was just a button/item selection touch event.

back in my code

 local scrollViewItemSelection = function(e)  
 if activeBtn ~= nil then  
 print("button " .. activeBtn.id .. " pressed");  
 activeBtn = nil;  
 end  
 end

it’s late and i’m not sure if i’m explaining this correct, or this solution is even ideal… but it works for me :stuck_out_tongue:
