My tableView goes to the top of the devices screen but I want the category to stop a little below the top of the screen. I’ve snooped around
tableView.\_view
and tried setting
tableView.\_view.\_rows[3].y
where 3 is the category row, when it reached the spot I want it to stop. I also tried a few others but nothing worked.
Is this possible?
I guess what you mean is that your tableView goes to the top but when it encounters category row it won’t go to the top but will stop a little bit below right?
Then solution is simple on OnRowTouch add if statment, for example : (pseudo code)
for i=1 , #rows
if row[i].isCategory then
if row[i].y > 600 then
stop Scrolling
end
end
end
If you want me to fix it for you submit your code since i am lazy bastard to implement this myself.
Ok say the top of my tableView is 0. The standard category row will stop when its top also reaches 0, but I want the category to stop at say 100 instead of 0.
Your method is similar to mine. The only way to get “rows” is by using
tableView.\_view.\_rows
correct?
If so, it does change the y value of the row when I print it, but it doesn’t change the actual position of the row.
Also, onRowTouch only gets called when you touch or release a row. I think the tableView listener would be a better function to put it in since it gets called every time the tableView moves

The tableView is set to mimic the iOS native tableView where categories scroll up and stick to the top until the next category replaces them. There are no controls to position this.
That said, widgets are an open source library on the Corona Labs github repository: https://github.com/coronalabs/framework-widget
Feel free to download and modify to your heart’s content.

Thanks Rob. Downloaded the widgets and followed your post here http://forums.coronalabs.com/topic/34183-widgets-20-open-source/ but corona is still using the built in widget, not the new one. I’m not sure what I’m doing wrong
Nevermind, I don’t know what I did but I got it working.
To answer my original question, if you want the category to stop at 100 pixels then add “+ 100” to the following lines in widget_tableview.lua
804
self.\_currentCategory.y = self.\_currentCategory.contentHeight \* 0.5 + 100
839 & 840
if self.\_currentCategory and self.\_currentCategory.y ~= self.\_currentCategory.contentHeight \* 0.5 + 100 then self.\_currentCategory.y = self.\_currentCategory.contentHeight \* 0.5 + 100 end
870 - Subtract instead of add
local rowTop = self.y + currentRow.\_view.y + view.\_height \* 0.5 - 100
881
self.\_currentCategory.y = currentRow.\_top - ( self.\_currentCategory.contentHeight \* 0.5 ) + 100I guess what you mean is that your tableView goes to the top but when it encounters category row it won’t go to the top but will stop a little bit below right?
