Hi Vasek,
If you add “return true” at the end of the touch listener for the overlay rectangle, it should receive all events. But then, how will the user interact with the tableView below?
Best regards,
Brent
Hi,
you are right. Adding return true to the touch listener will block event to propagates towards table view below. This is certainly not what i’m trying to achieve there 
I jut need to keep table view interacting with user and to capture users touch movements simultaneously.
Best Regards

Hi Vasek,
I still don’t understand the usage case. Do you want the ability to “drag” the table view around the screen, but it also still behaves as normal when the user touches the actual table view?
Brent
Yes, that is it. I have several table views ordered in columns and I just need to swipe/drag between them.

Hi Vasek,
I can’t think of any “perfect” way to maintain tableView functionality (flicking it up and down) while also being able to drag it around the screen. You may want to place some kind of “frame” around it with a visual indication that the user can move it around by dragging on that part of the overall element, but not by moving around on the tableView itself.

If I understand correctly I think Vaclav wants to go between tableviews like a slideview. Maybe this helps. I added a tableview listener and propagate the touches over to the touch rect.
[lua]
– touch listener
local function myTouchListener( event )
if ( event.phase == “began” ) then
--code executed when the button is touched
print( "object touched = "…tostring(event.target) ) --‘event.target’ is the touched object
elseif ( event.phase == “moved” ) then
--code executed when the touch is moved over the object
print( “touch location in content coordinates = “…event.x…”,”…event.y )
elseif ( event.phase == “ended” ) then
--code executed when the touch lifts off the object
print( "touch ended on object "…tostring(event.target) )
end
--return true --prevents touch propagation to underlying objects
end
– called when new row is added
local function onRowRender(event)
– Get reference to the row group
local group = event.row;
local h = event.row.contentHeight;
local w = event.row.contentWidth;
– fill row with red rectangle
local rect = display.newRect(group, w*0.5, h*0.5, w, h*0.9);
rect:setFillColor(1,0,0);
end
local group = display.newGroup();
– table view size
local rowHeight = 100; – content px
local rowCount = 10;
local tableViewHeight = display.contentHeight*0.5;
local tableViewWidth = display.contentWidth*0.5;
local tableViewTop = (display.contentHeight - tableViewHeight)*0.5;
local tableViewLeft = (display.contentWidth - tableViewWidth)*0.5;
– rectangle size
local rectHeight = display.contentHeight;
local rectWidth = display.contentWidth;
– add table view
local touchDetectingRectangle = display.newRect(group, display.contentCenterX, display.contentCenterY, rectWidth, rectHeight);
touchDetectingRectangle:setFillColor(0.5,0.5);
local function tableViewListener(event)
myTouchListener({phase = event.phase, target = touchDetectingRectangle, y = event.y, x = event.y})
end
local widget = require(“widget”)
local options =
{
top = tableViewTop, left= tableViewLeft,
hideBackground = true,
onRowRender = function(event) onRowRender(event) end,
width = tableViewWidth,–self.width-2*self.rowMargin,
height = tableViewHeight,
listener = tableViewListener,
isBounceEnabled = false;
--noLines = true,
}
local levelsTable = widget.newTableView( options);
group:insert(levelsTable);
local rowOptions =
{
rowHeight = rowHeight,
rowColor = { default={0,0}},
}
for i=1, rowCount do
levelsTable:insertRow(rowOptions)
end
– add event capturing rectangle over table view
touchDetectingRectangle:toFront(); – to make sure thad rectangke is abowe the table view
touchDetectingRectangle:addEventListener( “touch”, myTouchListener )
[/lua]
Hi jojonsson,
you get it right. I’m trying to do slideview containing table views.
The event propagation you proposed works. But trouble is, that table view touch events are bit different. All events have event.phase == “begin” until the first change in Y direction occurs. So if you manage to do you move perfectly horizontal no scrolling wil occur. This is of course very special case so i decided to neglect it for now.
Thank you very much for your help !
