Hi :)

I have a problem :S
In my addon i use the function "CreateFrame()" to create some
buttons and frames
It is a chat addon and one frame and one button are dedicated to each
person.
So far no problems.

But when i close the button/frame, (When i'm finshed taking to a person),
is there any posibility to remove the frame and button i have created for this person ??

Ex:
a person named "Dan"
I create some variables for Dan:

WE2.index["Dan"] = {
tab = "danTab",
frame = "danFrame",};

Then i create the frame/button:

CreateFrame("ScrollingMessageFrame", "danFrame", nil, "WE2_chatFrame")
CreateFrame("Button", "danTab", nil, "WE2_Tab")

When i'm done talking with "Dan" i remove his variables and frame/button

WE2.index["Dan"] = nil;

!!and here comes the problem!!

now i only know how to hide the frames and buttons i've made.
I need to remove them, so it can be possible to create them again.

is there any way to remove the frame/Button ??? plz help

Sincerely
Unibus

One more thing.

Is it possible to check if a frame/Button excists before you create it

Ex.
If i create a button and hide it

button = CreateFrame("Button", "test", nil, "WE2_Tab");
button:Hide();

If i now create a new button. Can i check if it already excists ??
Ex. If i wanted to create the same button again

if(test == not a button) then <-or something
   button = CreateFrame("Button", "test", nil, "WE2_Tab");
else
   Print("test is already a button")
end

Keep your referance to the button and either do:

if not button then button=CreateFrame(blah) end

or

button = button or CreateFrame(blah) -- will create frame if button is nil/false

As for the first post, do you mean you want to delete the frames??

Edit: Well, could you explain your exact use for these, because I have a feeling you're going about something wrong.

I don't think frames are garbage collected... after you create them they will exist forever ;)

created frames can't be destroyed.
even if you try to overwrite frames by creating a new one with the same name, the already existing frame will be still existing as well the new one. Which one you get by calling getglobal(framename) i don't know.
if you want to recycle your frames i advise to take a look at Pitbull (it has two funcs to recycle frames).

This is true. Erasing all Lua references to the frame doesn't destroy it.

Your best bet is to use a frame recycling method or create your frames beforehand and simply change their respective attributes as desired when needed.
