This function gets the color of a gridlist item.

Syntax

int int int int guiGridListGetItemColor ( element gridList, int rowIndex, int columnIndex )

OOP Syntax Help! I don't understand this!

Method: GuiGridList:getItemColor(...)


Required Arguments

  • gridList: The grid list element
  • rowIndex: Row ID
  • columnIndex: Column ID

Returns

Returns four int values, representing the amount of red, green, blue and alpha if successful. false otherwise.

Example

Click to collapse [-]
Client

This example creates a player list on the right of the screen and fills it with players online and sets the grid list item color according to their nametag color. When the player clicks on a grid list item, it'll output the color of it. 

function createPlayerList ( )
	--Create the grid list element
	local playerList = guiCreateGridList ( 0.80, 0.10, 0.15, 0.60, true )
	--Create a players column in the list
	addEventHandler ( "onClientGUIClick", playerList, onGridListClick, false )
	local column = guiGridListAddColumn( playerList, "Player", 0.85 )
	if ( column ) then --If the column has been created, fill it with players
		for id, player in ipairs ( getElementsByType ( "player" ) ) do
			local row = guiGridListAddRow ( playerList )
			local r, g, b = getPlayerNametagColor ( player ) -- We get the player nametag color.
			guiGridListSetItemText ( playerList, row, column, getPlayerName ( player ), false, false )
			guiGridListSetItemColor ( playerList, row, column, r, g, b ) -- We set the grid list item color to the returned values of getPlayerNametagColor.
		end
	end
end
addEventHandler ( "onClientResourceStart", resourceRoot, createPlayerList )

function onGridListClick ( )
	local row, col = guiGridListGetSelectedItem(source)
	if ( row and col and row ~= -1 and col ~= -1 ) then
		local r, g, b, a = guiGridListGetItemColor ( source, row, col )
		outputChatBox ( "Red: ".. r, 255, 0, 0 )
		outputChatBox ( "Green: ".. g, 0, 255, 0 )
		outputChatBox ( "Blue: ".. b, 0, 0, 255 )
		outputChatBox ( "Alpha: ".. a, 255, 255, 255 )
	end
end
