I am having some issues with ScrollView

Firsly, my scroll view consists of many large buttons which take a large portion of space in the scrollview. If I try to scroll but initially put my finger on a button the scrollview will not scroll.

So if I want to scroll i need to avoid initially tapping the buttons which is an effort and not a very easy one. I need to be able to scrolll even if my initial touch was on a button. The focus on the button is removed when my finger is no longer on it but I still cant scroll. How can I fix this?

I am using widget.newScrollView() and widget.newButton()

Secondly, my scrollview is a horizontal scrollview. And the horizontal scrollbar is not displayed. Why?

Heres the code

scrollView = widget.newScrollView({ width = \_W, height = \_H, scrollHeight = \_H\*2, locked = false, hideBackground = true, horizontalScrollDisabled = false, verticalScrollDisabled = true, hideScrollBar = false, isBounceEnabled = true, listener = onScroll }) scrollView.anchorX = 0 scrollView.anchorY = 0 scrollView.x = 0 scrollView.y = 0

You need to listen for touch events. If a touch moves beyond a threshold distance (usually 3% of the screen width) you pass the touch to the scrollview control below by using takeFocus(). Use the onEvent listener property of the button.

Thanks that solved the first issue. But I still dont see the scrollbar. Any ideas why?

What is your config.lua?

Hi Rob, here is my config.lua

local aspectRatio = display.pixelHeight / display.pixelWidth application = { content = { width = aspectRatio \> 1.5 and 320 or math.ceil( 480 / aspectRatio ), height = aspectRatio \< 1.5 and 480 or math.ceil( 320 \* aspectRatio ), scale = "letterbox", xAlign = "center", yAlign = "center", fps = 60, imageSuffix = { ["@1x"] = 1.5, ["@2x"] = 2, ["@3x"] = 2.4, } },

Well your config.lua is not the cause.

#7

The scrollview takes up the whole screen. I removed every other display object and still cant see the horizontal scrollbar. What may be the issue?

#8

Do you have more content than the screen?  Are you scrolling and looking for it, or are you just looking for the scroll bar without trying to scroll?

#9

I have more content than the screen and I am scrolling and looking for it.

#10

I hate to have to keep asking basic questions, but have you looked in your console log for any errors?

Also can you put together a simple project with your scrollView and the assets needed to run so we can take a look at it?
