Here’s what I did:
[lua]
local slide = {
left = 0,
right = display.contentWidth * 2 / 3,
position = “left”,
startthreshold = 5,
swipethreshold = 75
}
local tableview = widget.newTableView({
left = slide[slide.position],
width = display.contentWidth,
height = display.contentHeight
})
function tableview:position(leftorright)
if self.x == slide[leftorright] then return end
slide.position = leftorright
self.x = slide[leftorright]
end
function tableview:restoreposition()
self:position(slide.position)
end
function tableview:switchposition()
local leftorright = “left”
if slide.position == “left” then leftorright = “right” end
self:position(leftorright)
end
– FIXME; can break on any new widget version,
– but for now probably a better solution than keeping a fork of the widget library.
– The problem is that the TableView widget uses up all touch hook points for its
– implementation of table scrolling and row selecting & swiping, and doesn’t
– provide any possibility for touch extension through its API.
– The tableview[2] part is the dirty hack here.
local view = tableview[2]
local widgettouch = view.touch
function view:touch (event)
local direction = “left”
if event.x > event.xStart then direction = “right” end
if direction ~= slide.position then
local distance = math.abs(event.x - event.xStart)
if “moved” == event.phase then
if distance > slide.startthreshold then
tableview.x = tableview.x + (event.x - slide.prevx)
end
elseif “ended” == event.phase or “canceled” == event.phase then
if distance > slide.swipethreshold then
tableview:switchposition()
else
tableview:restoreposition()
end
end
end
slide.prevx = event.x
widgettouch(view, event)
return true
end
[/lua]
