Getting the text of a button when clicked

sweede · 10-20-05, 02:56 PM

I'm modifying an existing addon that sorts people who send a tell by order of their DKP values.

so you would have a list like

Joe dkp 302
hank dkp 156
frank dkp -1

I would like to be able to click on one of the above names and have a box pop up saying "Award loot to playername", and then i hit yes / no and it announces to raid.

The problem i have is getting from the buttom in the XML to the function in the lua file.

the XML....

Code:

<Button name="DKPBidAuctionButtonTemplate" virtual="true">
		<Size>
			<AbsDimension x="160" y="16" />
		</Size>
		<Layers>
			<Layer level="BORDER">
				<FontString name="$parentText" inherits="GameFontNormalSmall" justifyH="LEFT">
					<Size>
						<AbsDimension x="160" y="14" />
					</Size>
					<Anchors>
						<Anchor point="TOPLEFT">
							<Offset>
								<AbsDimension x="2" y="-1" />
							</Offset>
						</Anchor>
					</Anchors>
				
				</FontString>
			</Layer>
		</Layers>
		
		<HighlightTexture file="Interface\QuestFrame\UI-QuestTitleHighlight" alphaMode="ADD">
			<Size>
				<AbsDimension x="160" y="16" />
			</Size>
			<Anchors>
				<Anchor point="TOP">
					<Offset>
						<AbsDimension x="0" y="0" />
					</Offset>
				</Anchor>
			</Anchors>
		</HighlightTexture>
		<Scripts>
			<OnClick>
				DKP_Bid_Bidder_OnClick();
			</OnClick>
		</Scripts>
	</Button>				
.. some more stuff ....
<Button name="DKPBidAuctionButton1" inherits="DKPBidAuctionButtonTemplate" id="1">
				<Anchors>
					<Anchor point="TOPLEFT" relativeTo="DKP_Bid_GUI_AuctionInfo">
						<Offset>
							<AbsDimension x="10" y="-30" />
						</Offset>
					</Anchor>
				</Anchors>
			</Button>
x 10

The lua code right now is simply

Code:

function DKP_Bid_Bidder_OnClick()
 		DEFAULT_CHAT_FRAME:AddMessage("wtf do i put here to get the name or text of what i click on!!!!");
end

Thanks very much !!!!

function DKP_Bid_Bidder_OnClick()
DEFAULT_CHAT_FRAME:AddMessage("wtf do i put here to get the name or text of what i click on!!!!");
end

When this is called, the global variable "this" is the frame that called it.

this:GetName() will be the name of the button that called it. Another good method is to number your controls like you did there. You have id="1" in the button, so you can do button=this:GetID()

<Button name="DKPBidAuctionButton1" inherits="DKPBidAuctionButtonTemplate" id="1"/>
<Button name="DKPBidAuctionButton2" inherits="DKPBidAuctionButtonTemplate" id="2"/>
<Button name="DKPBidAuctionButton3" inherits="DKPBidAuctionButtonTemplate" id="3"/>
<Button name="DKPBidAuctionButton4" inherits="DKPBidAuctionButtonTemplate" id="4"/>
etc

When they click the third button:
button = this -- button == the frame DKPBidAuctionButton3 itself
buttonName = this:GetName() -- button == "DKPBidAuctionButton3"
buttonID = this:GetID() -- button == 3

lol yeah and to get the text

local buttontext = this:GetText() or simillar should work
