MerchantItem frame : its name...

[adriweb]

Hey everybody,

for my addon VendorSearch, I come with a solution or searching, and it's so hide the Items' frame if it's not matching the keyword you're looking for.

Technically, it works.

But I still have a problem when I want to get the frame name and to Hide() it.

Here is the code :

PHP Code:

 f=CreateFrame("Frame","MerchantItem" .. i) -- i is from a for loop and start from 1, and go to the number of the total items from this vendor
if /code/ then
  f:Show();
      /Some other code/
else
  f:Hide();
      /Some other code/
end 


I actually tried a lot of combinations using the frames name for MerchantItem, but because the name of the frame is apparently not a string, it maybe doesn't concatenate with the value of "i"...

but it's basically the equivalent of something like that, that I want :

/script MerchantItem2:Hide()

and that works.... All I can't get is the number after the frame name....


Thanks for your help !

CreateFrame(...) creates a new frame and then you hide it or show it. I guess thats wrong.

You need to get the frame somehow. _G["MerchantItem"..i]:Hide() should work.

Thanks !

actually, I found a way just before to see your answer :

f = getglobal("MerchantItem" ..i)

Yeah it is almost the same thing. I think _G[] is faster/better because that way the table is accessed directly.

I think many developers do:

local G = _G
...code...
local frame = G["FrameName"]
...

I think thats the cleanest way too. Someone correct me if I'm wrong.

well, that sounds interesting,

thanks

getglobal is just a useless function wrapper to _G. Basically, getglobal is this:

function getglobal(x)
return _G[x]
end
