This function sets a Item Data associated to a grid list item.
Note: This function will only work after you set the item's text using guiGridListSetItemText!

Syntax

bool guiGridListSetItemData ( element gridList, int rowIndex, int columnIndex, var data )

Required Arguments

  • gridList: A gridlist element of the data you wish to set to
  • rowIndex: The row of the item you wish to set to
  • columnIndex: The column of the item you wish to set to
  • data: The data you wish to set to the item.

Returns

Returns true if the data was set successfully, false otherwise

Example

In this example, the gridlist shows the list of players without their color codes and outputs their names with color-codes at the chatbox when player is selected. 

function showPlayers()
    local window = guiCreateWindow(0,0,500,400,"Window example - Title",false) -- Create the window
    grid = guiCreateGridList(0,0,100,300,false,window) -- Create the gridlist
    local column = guiGridListAddColumn(grid, "Players online", 0.9) -- Create a column
    showCursor(true)--show cursor
    for index,player in ipairs(getElementsByType("player")) do -- Loop through all players
        local row = guiGridListAddRow(grid) -- Add a row
        guiGridListSetItemText ( grid, row, column, (string.gsub ( getPlayerName(player), '#%x%x%x%x%x%x', '' ) or getPlayerName(player)), false, false) -- Set it's text to the player's name excluding colorcodes
        guiGridListSetItemData ( grid, row, column, getPlayerName(player)) -- Set it's data to the player's name with colorcodes
    end
end
 
function outputPlayerName()
    if source == grid then -- If the player clicked something in the grid
        local selectedRow, selectedColumn = guiGridListGetSelectedItem(grid) -- See which player he selected
        local playerName = guiGridListGetItemData(grid, selectedRow, selectedColumn) -- Get the selected player's name with color codes   local playerNameWithoutColorCodes = guiGridListGetItemText(grid, selectedRow, selectedColumn) -- Get the selected player's name without color codes
        local playerNameWithoutColorCodes = guiGridListGetItemText(grid, selectedRow, selectedColumn) -- Get the selected player's name without color codes
        if playerName and playerNameWithoutColorCodes then -- If he really selected something
            outputChatBox("The selected player's name without color codes : "..playerNameWithoutColorCodes, 255,255,255,false) -- output without color codes
            outputChatBox("The selected player's name with color codes : "..playerName, 255,255,255,false) -- output with color codes
            outputChatBox("The selected player's name with colors : "..playerName, 255,255,255,true) -- output with colors
        end
    end
end
 
addEventHandler("onClientGUIClick", getRootElement(), outputPlayerName)
addEventHandler("onClientResourceStart", getResourceRootElement(getThisResource()), showPlayers)
