One question about this, can I also adapt it so that I have a table with all frames where I needed the backdrop template and add it here automatically with a for-loop?

Something like that?

It would be
unless the table stored the reference to the created frame rather than its name.

It would depend on whether the template (common method for adding a mixin) adds any frame elements required by the mixin. If all it's doing is applying a bunch of methods to an already existing (or created in the process) frame then that would work. Or you could add the template frame elements "manually" when you apply the mixin if you weren't responsible for creating the frame(s).

p3lim's post seems to indicate, for backdrops, that it's just applying the mixin methods.

You just need to make sure you've applied the mixin before any of your code calls any of the methods on the frames.

Thanks for the explanation.
In my UI I work with a set template function that controls the appearance of the frames. That's where I've added the mixin. Works well so far and so far there were no problems when testing.

Can someone explain the SetBackdrop-fuckup for a dummie like me and how to fix LibQTip (https://www.wowace.com/projects/libqtip-1-0/) as an example?

I tried replacing line 364
tooltip = CreateFrame("Frame", nil, UIParent)
with
tooltip = CreateFrame("Frame", nil, UIParent, "BackdropTemplate")

and as this didnt worked I added ', "BackdropTemplate"' to every CreateFrame which doesnt work either.

What am I doing wrong?

TIA!

I've tested it with a simple tooltip and it works with only the line 364 changed.
Make sure you load your altered version and no other older version is available.

Edit: My test was too simple. Had no release implemented. There is more to it.
Edit2: Function in Line 179 (only clear backdrop if the frame has it implemented)


Line 226

There a several places the library would need to be updated depending on which parts you are using.

Things like around line 517 in InitializeTooltip(tooltip, key)
would be followed by

@Rilgamon and @Fizzlemizz
thank you both very much :banana:

@Fizzlemizz:
yes I noticed and did so following your example
end result here: https://pastebin.com/DxRyHy9C

A side note for future travelers, applying the Mixin directly would primarily be used for frames you didn't create but wanted to set a backdrop on (as p3lim pointed out earlier in the thread).

In the library, because lines are created by it, instead of applying the Mixin at
you could inherit the template where the line is created

Both methods work but the second might save some code if after frame creation, you branch into different functions that also apply backdrops but possibly using different styles etc. (the template does the job of applying the mixin without extra lines of code)

Sorry for another dumb question but how do I get the BackdropTemplate when the frame is created in an xml?

I need to know what to write in place of the ???.

TIA

Sorry if I intrude .. Could someone help me understand how to fix the LUA errors resulting from the "backdrop" on the Stuf Unit Frames addon? (https://www.wowinterface.com/downloa...?id=11182#info)
Thanks a lot..

Did everyone else get a darkened frame after applying the new backdrop template ?

If you did, where did you find the issue was ?


Edit:
Nevermind, it appears the addition of the backdrops to certain frames on nUI affected the current alpha state visual. Simply changing them from 0.75 to 0.35 allowed the text to display easier.

I have noticed that SetBackdrop() now creates 9 textures instead of the typical 8 (4 edges + 4 borders). I have no idea what the last texture is.

I have noticed this because I use backdrops to create 1px borders on casting bars, and I need to access those textures to change the backdrop's Layer (so it doesn't get covered by the StatusBar filling texture).

8 textures for edges, 9th for background.

Maybe the background is the texture messing up some of nUI's click buttons. Thankfully so far thats all that is affected but I wouldn't be surprised if something appears sooner or later.

When using the addon ItemRack https://www.curseforge.com/wow/addons/itemrack I am getting the following error:

Message: ..\AddOns\ItemRack\ItemRack.lua line 1733:
attempt to call method 'SetBackdropBorderColor' (a nil value)

I tried updating ItemRack.lua but I've had no success whatsoever. Is there some kind soul out there who could take a quick look and see what might possibly have to be changed to get this addon working correctly once more?

Thanks in advance!

---------------------

Never mind, I managed to figure it out myself.

Hi,

is there anyway to fix the Backdrop for (https://www.curseforge.com/wow/addon...alui-bossskins)?
Since the 9.0.1 update the Background for Bars and Icons with this DBM skin is gone

First thing is is your installation of RealUI up to date? The second thing is that addon hasn't been updated since 2016, so, it's probably a bit out of date by now (what with the updates to the game (9.0.1 changedthebackdrop coding so...)).

This Addon always ran without RealUI, wich i dont use, also it ran perfectly fine until the 9.0 update, it still works perfect actually, only the background of the bar and icon is missing now

Like I said ^^^^... I'm sorry that I can't help you with code, but if you search around a little I'm sure you'll find the information. I know there's a thread here for backdrop problems, I just don't know where it is. :o In fact ... this is one of the threads for backdrop problems. DOH!!!
