Accessing ScrollingMessageFrame

hop · 07-26-06, 11:21 AM

I'm sure there is some basic thing I'm not doing here, but I've searched for examples and haven't found any.

I'm using wowuides and created an XML form. I added a button that hides the form, events for moving, etc. and all works fine. I then drew a ScrollingMessageFrame on my form, and tried to add a message to it from my LUA, and I got an error, so I read the fact and tried using the suggestion local label = getglobal("ProjectForm".."VersionText".."Label") *changing the names of course* and now I get the error attempt to index local `myobj' (a nil value) .

The name of the ScrollingMessageFrame is $parentScrollingMessageFrame1 and the form is HopWorksTools01. Here is how I tried to access it from my LUA code

Code:

function print(text)
    DEFAULT_CHAT_FRAME:AddMessage(text)
    local myobj = getglobal("HopworksToolsForm01".."ScrollingMessageFrame1".."ScrollingMessageFrame")
    myobj:AddMessage(text)
end

I also tried

Code:

local myobj = getglobal("HopworksToolsForm01".."ScrollingMessageFrame1")

because I didn't know what that third field was for. From the example, I assume it's for the type of the object.

Can someone tell me what I'm missing here?
Thanks!

The form:

Code:

local myobj = getglobal("HopworksToolsForm01".."ScrollingMessageFrame1")

is correct as you can access the frame directly. To be sure, name your ScrollingMessageFrame something like HopworksToolsSMF1, and do a call

Code:

HopworksToolsSMF1:AddMessage(text)

to see if that works (no need for a getglobal call).

Hey Nulkris! Thanks for responding.

I tried what you suggested and it worked just fine. I must have had $parent in front of the name last time, and I thought it had to be there to make the object visible. It didn't make sense to me, but I'm still new at XML and LUA, although LUA is a bit like PHP to me.

Anyway, thanks for clearing up that noob question for me. =)

Now I'm having another issue with that scrolling message frame object...

I can't seem to get it to display more lines. I put in 100 for maximum lines in the behavior properties, but it always reverts back to 8 lines. I save it, exit wowuides, start it again, and load my project, and again it is set to 8 lines. What am I doing wrong there?

Sorry to keep beating a dead horse here, but I want to use this control to display output from my functions, and filtered chat data, and 8 lines isn't gonna do it. =)

Thanks again for all the help!

Ok, looks like I missed out a few things on the skin file, you can unzip the attachment to this message, and overwrite the BasicSkin.xml file in the skins directory to get it working properly.

Yes sir! That did it! Thanks for the personal attention!

Now one last thing, and I wouldn't ask it except a wowwiki search on this control turned up very little info.

How do you attach a scroll bar? Hmm. Come to think of it, the original chat windows don't have scroll bars.

Sigh. I guess I could use a slider. The important thing is I can see more lines now. Thank you!

Can I get your thoughts on that scroll bar idea though?

If I haven't said it sooner, I really love this application. It's throwing an exception error when I close a project and then reopen it, but it's not lethal. Here's the info on the error...
