How to get 1st line selected on DListView ?

[lotus006]

I tried some code to get work SelectFirstItem() but nothing seem to work on my code. ( I think is something wrong between the line 43 - 50 )
I have stack overflow in error.

Some one can explain me how work the SelectFirstItem() with DListView ?

Thanks in avance.

[_nonSENSE]

[URL="http://wiki.garrysmod.com/?title=DListView.GetSelected"]This [/URL]returns a table. To get the first value, use [1] obviously.

[lotus006]

I'm not sure about the [1] but can you tell me if i'm in the good way ?

[lua]DermaWeaponsListView.OnRowSelected = function(panel , line)

DermaWeaponsListView:GetSelected(1)

local LineSelect = DermaWeaponsListView:GetLine(line):GetValue(1)
LabelNameSwep.Paint = function()
LabelNameSwep:SetText(LineSelect)
end
end[/lua]

DListView.GetSelected() does not take arguments. So no, it won't be GetSelected(1). Think of it like this:

[lua]local x = DermaWeaponsListView:GetSelected()
local item = x[1]

-- is the same as

local item = DermaWeaponsListView:GetSelected()[1][/lua]
