Hello community,

how can I iterate through a list widget (all items or all selected in there), which I implemented this way:

Code: Select all

ir = ir + 1; -- incremented
d = vlc.dialog("My new extension")
deleteListGUI = d:add_list(1,7,10,10)
deleteListGUI:add_value("string", ir)

-- how to iterate through deleteListGUI?

edit:

Code: Select all

	
	-- remove selected items from delete-list
	function removeFromDeleteList()
		local selected = deleteListGUI:get_selection()
		for name, value in pairs(selected) do
			vlc.msg.dbg("name: " .. name .. " value: " .. value)
			deleteListGUI:add_value("", name) -- overwrite, want to delete
			d:update() -- but the overwritten item is already seen in the list and another empty item appends to the list
			-- I want to delete these value's from deleteListGUI but keep the unselected items in this list
		end
	end

-- how looks the function to get all items in deleteListGUI?
function getAllItemsInList()
-- ???
end

w:clear(): Clear a list or drop_down widget. After that, all values previously added are lost.

You have a table (array) of items listed in a list widget. Then parse a selection and delete all selected items in the table. Then clear the list widget and list items of the modified table.

You're right. This is a good idea. Thanks. If there was more list widget functions the performance was better. Now I always have to update the list, clear the guiList and go through (for) the updated list and add all values into the guiList again.
