This function returns the items selected in the specified grid list.

Note that for some reason the column ID is 1 lower than it should be, for example 0 is returned but if you try and get the text for column 0 there is nothing, but column 1 has what you clicked on.

Syntax

table guiGridListGetSelectedItems ( element gridList )

OOP Syntax Help! I don't understand this!

Method: GuiGridList:getSelectedItems(...)
Variable: .selectedItems


Required Arguments

  • gridList: The grid list which selected items you want to retrieve.

Returns

Returns a table over the selected items in the grid list in this format: 

table = {
    [1] = {
        ["column"], -- has the first selected item's column ID
        ["row"] -- has the first selected item's row ID
    },
    [2] = {
        ["column"],-- has the second selected item's column ID
        ["row"] -- has the second selected item's row ID
    },
    ...
}

if everything was successful or false if invalid arguments were passed.

Example

Example

-- This example creates a grid list of all players, clicking "Selected" button will then use guiGridListGetSelectedItems to show all selected items.
playerWindow = guiCreateWindow(526, 230, 291, 284, "", false)
gridlistPlayers = guiCreateGridList(9, 23, 272, 201, false, playerWindow)
guiGridListAddColumn(gridlistPlayers, "Players", 0.9)
guiGridListSetSelectionMode(gridlistPlayers, 1) -- So can select many players
for _, players in ipairs(getElementsByType("player")) do 
	local row = guiGridListAddRow(gridlistPlayers)
	guiGridListSetItemText(gridlistPlayers, row, 1, getPlayerName(players), false, false)
end 
buttonSelectedPlayer = guiCreateButton(9, 227, 272, 20, "Selected", false, playerWindow)

function seeSelected()
	local selected = guiGridListGetSelectedItems(gridlistPlayers)
	for i, data in ipairs(selected) do -- Loops through all selected items
		outputChatBox(guiGridListGetItemText(gridlistPlayers, data["row"], 1)) -- Shows player name of selected players
	end
end
addEventHandler("onClientGUIClick", buttonSelectedPlayer, seeSelected, false)
