Example

This code creates a grid list and fills it with the names of the connected players. When the user selects an item, its text (the player name) will be output in the chat box. 

function createPlayerList ()
        -- Create the grid list
        playerList = guiCreateGridList ( 0.80, 0.10, 0.15, 0.60, true )
        -- Create a players column in the list
        local column = guiGridListAddColumn( playerList, "Player", 0.85 )
        if ( column ) then         -- If the column has been created, fill it with players
                for id, playeritem in ipairs(getElementsByType("player")) do
                        local row = guiGridListAddRow ( playerList )
                        guiGridListSetItemText ( playerList, row, column, getPlayerName ( playeritem ), false, false )
                end
                addEventHandler ( "onClientGUIClick", playerList, click )
        end
end
addEventHandler ( "onClientResourceStart", resourceRoot, createPlayerList )

function click ( button, state, sx, sy, x, y, z, elem, gui )
        -- if state is down ( not to trigger the function twice on mouse button up/down), clicked gui and the element is our player list
        if ( ( state == "down" ) and ( gui == true ) and ( source == playerList ) ) then
                -- get the player name from the selected row, first column 
                local playerName = guiGridListGetItemText ( playerList, guiGridListGetSelectedItem ( playerList ), 1 )
                outputChatBox ( playerName )     -- output it to chat box
        end
end
