Dynamic List Refresh Behavior about gooey HOT 3 CLOSED

I started looking at this today, but have so far not really figured out what goes wrong while refreshing the list.

from gooey.

No worries, thanks for taking a look though! I was able to resolve this issue by trimming down the refresh function by moving the gui node deletion and creation steps out. Instead, this occurs during initialization an the new nodes are 'reparented' on refresh using gui.set_parent(node, e.nodes[hash("dynamic_list_item")])

The only caveat with this method is that I had to manually set the item index. Otherwise, you will not be able to select a list item with scrolling first.

Still not sure why the previous behavior occurs, unfortunately

I'm not sure what you are doing wrong as the example you've included is relatively complicated to follow. But let's instead start by looking at the horizontal list example provided here in this repository:

https://github.com/britzl/gooey/blob/master/example/horizontallist.gui_script#L75-L77

Open that example and modify the list click behaviour to remove the item that is clicked:

	local list = gooey.horizontal_dynamic_list("dynamiclist_bg", "dynamiclist_stencil", "listitem_bg", self.list_data, action_id, action, nil, function(list)
		print("selected dynamic list item", list.selected_item.index, list.data[list.selected_item.index].text)
		local v = table.remove(list.data, list.selected_item.index)
		print("removed", v.text)
		gooey.horizontal_dynamic_list("dynamiclist_bg", "dynamiclist_stencil", "listitem_bg", self.list_data, nil, nil, nil, nil, refresh_dynamiclist)
	end, refresh_dynamiclist)

What we do here is to remove the item from the list.data and then we call the gooey.horizontal_dynamic_list() function again to make sure the internal list state is updated and the visuals refreshed. Try the example with the modification above and then click on items in the list to remove them. Notice that the list is refreshing properly.
