This function creates a grid list GUI element. These are menu's which are designed in lists and can have multiple columns. A good example of a gridlist element can be found in MTA's settings box, under Controls.

Syntax

element guiCreateGridList ( float x, float y, float width, float height, bool relative, element parent )

Required Arguments

  • x: A float of the 2D x position of the GUI gridlist on a player's screen. This is affected by the relative argument.
  • y: A float of the 2D y position of the GUI gridlist on a player's screen. This is affected by the relative argument.
  • width: A float of the width of the GUI gridlist. This is affected by the relative argument.
  • height: A float of the height of the GUI gridlist. This is affected by the relative argument.
  • text: A string of the text that will be displayed by default in the edit box.
  • relative: This is whether sizes and positioning are relative. If this is true, then all x,y,width,height floats must be between 0 and 1, representing sizes relative to the parent.

Optional Arguments

NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.

  • parent: This is the parent that the gui gridlist is attached to. The relative argument must be true to use this. Sizes and positioning will be made relative to this parent. If no parent is passed, the parent will become the screen - causing relative positioning and sizing according to screen positioning.

Returns

Returns an element of the created gridlist if it was successfully created, false otherwise.

Example

Example 1: This example creates a player list on the right of the screen and fills 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
	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 )
			guiGridListSetItemText ( playerList, row, column, getPlayerName ( player ), false, false )
		end
	end
end

Example 2: This example creates a weapon selection screen, complete with a window, gridlist and a button. Users can select a handgun and an uzi. The window is not movable or sizable. 

--Setup some tables
handguns = {
"colt45",
"deagle",
"silenced" }

uzis = {
"Uzi",
"MP5",
"Tec-9" }

function setupWeaponSelection ( theResource )
	if theResource ~= getThisResource() then return end --if the resource started is not this one, dont bother creating the gui
	---Create a window for our spawnscreen, with the title "Select your weaposn".
	spawnScreenMenu = guiCreateWindow ( 0.15, 0.33, 0.7, 0.34, "Select your weapons", true )
	--create an OK button to allow the user to confirm their seclections, and attach it to the confirmSelection funnction
	spawnScreenOKButton = guiCreateButton ( 0.4, 0.85, 0.20, 0.15, "OK", true, spawnScreenMenu )
	--ensure the user doesnt move or resize our spawnscreen.
	guiWindowSetMovable ( spawnScreenMenu, false )
	guiWindowSetSizable ( spawnScreenMenu, false )
	--create our gridlist, which fills up most of the window.
	spawnScreenGridList = guiCreateGridList ( 0, 0.1, 1, 0.9, true, spawnScreenMenu )
	--Since we have 3 sets of weapons to select, we create 3 new columns, one for handgun, uzi and heavy weapon.
	guiGridListAddColumn ( spawnScreenGridList, "Handgun", 0.3 )
	guiGridListAddColumn ( spawnScreenGridList, "Uzi", 0.3 )
	-- next, we loop through our handguns table to add handgun items to the gridlist
	for key,weaponName in pairs(handguns) do
		--add a new row to our gridlist each time
		local row = guiGridListAddRow ( spawnScreenGridList ) --get our new row
		--next, we set that rows text to the weapon name.  Column is 1 since the "Handgun" column was created first.
		guiGridListSetItemText ( spawnScreenGridList, row, 1, weaponName, false, false )
	end
	--we repeat the process for other weapon lists, changing the column number
	row = 0
	for key,weaponName in pairs(uzis) do
		--we dont bother creating new rows, since we already have done that
		--next, we set that rows text to the weapon name.  Column is 2 since the "Uzis" column was created second.
		guiGridListSetItemText ( spawnScreenGridList, row, 2, weaponName, false, false )
		row = row + 1 --increase the row number
	end
end
addEventHandler ( "onClientResourceStart", getRootElement(), setupWeaponSelection )
