Changing layout settings without ReloadUI()

[Rainrider]

I'm currently making an GUI config for my oUF layout and would like to know what is changeable on the go without doing ReloadUI(). I don't need moving and scaling as those are perfectly done with oUF MoveableFrames. What I'm interested in are aura filtering and some basic click-casting. Currently I enable the aura filter based on a config option, so I assume it's then set at frame creation and would need a ReloadUI() to be changed. I didn't want to move this into the filter itself in order to spare a table look-up as UNIT_AURA is being fired quite a lot. Is this the only way and is my assumption right?

I apply my click-casting in :SpawnHeader

"oUF-initialConfigFunction", ([[
    self:SetWidth(110)
    self:SetHeight(11)
    self:SetAttribute("type3", "spell")
    self:SetAttribute("spell3", "%s")
]]):format(spellName)

and let the player specify spellName in the config. This would require a ReloadUI() too, wouldn't it? Could I avoid it somehow?

Some directions and links to layouts implementing some of these would be very appreciated. Changing frame size would be interesting too.

AuraFiltering and such is done through variables set on the element table on the frame. Just setting those variables and running :ForceUpdate() on the element or :UpdateAllElements() on the frame.

When it comes to your click-casting, oUF-initialConfigFunction is only a attribute on the header. You can change that one whenever you want (as long as you are out of combat). Note that its only ran no frame creation.

For the already created frames, just re-run :SetAttribute('spell3', 'spell') on all your frames after the user has made a change.

Changing frame size is really the same thing, re-run :SetSize() on all your frames and update oUF-initialConfigFunction to contain the correct sizes.

Thank you very much for your help, Haste.

How would I go for disabling frames like party, partypets etc.? Just call :Hide() on the corresponding header? If I remember correctly, oUF does not update frames that are not visible, is this right?

What about changing between horizontal and vertical party flow? My code for the later is:

local party
if (cfg.showParty) then
    if (cfg.horizParty) then
        party = self:SpawnHeader(
            "oUF_Rain_Party", nil, "party, raid",
            "showParty", true,
            "showRaid", true,
            "maxColumns", 4,
            "unitsPerColumn", 1,
            "columnAnchorPoint", "LEFT",
            "columnSpacing", 9.5,
            "oUF-initialConfigFunction", ([[
                self:SetWidth(110)
                self:SetHeight(22)
                self:SetAttribute("type3", "spell")
                self:SetAttribute("spell3", "%s")
            ]]):format(spellName)
        )
        party:SetPoint("LEFT", UIParent, "BOTTOM", -231.25, 130)
    else
        party = self:SpawnHeader(
            "oUF_Rain_Party", nil, "party, raid",
            "showParty", true,
            "showRaid", true,
            "yOffset", -27.5,
            "oUF-initialConfigFunction", ([[
                self:SetWidth(110)
                self:SetHeight(22)
                self:SetAttribute("type3", "spell")
                self:SetAttribute("spell3", "%s")
            ]]):format(spellName)
        )
        party:SetPoint("TOPLEFT", UIParent, 125, -25)
    end
    party:Show()
end

Also, is there a table or a function in oUF returning all enabled frames? I ask this as I have some elements I'd like the user to be able to change that are enabled on almost every frame (like debuff highlighting) and it would be then tedious to call :ForceUpdate on them through the global frame names and checking whether the element is enabled.

It depends. For single frames you can just call frame:Disable(), then later when you want it to work again: frame:Enable().

Headers are slightly worse however:
If the header has a visibility state, then you will have to disable it (yours have): UnregisterAttributeDriver(header, 'state-visibility') -- you probably want to cache the value tho'
After this you can simple call header:Hide().

Just change the attributes and hide/show the header. Alternatively you can wait for the next header update cycle.

You will have to maintain this list yourself. I currently only maintain a list of created frames and unit -> frame mapping in oUF, and the later is removed in 1.6.x.

Remember that the style function is called as (object, objectUnit, not header), so you can easily maintain a list of single-spawned frames through it.

I checked SecureStateHeaderTemplate code, ouf.lua and read the whole 25th chapter of "World of Warcraft Programming" and wasn't able to find out how to get the currently set value of the "state-visibility" driver. header:GetAttribute("state-visibility") and the like didn't get me something either. In my case it is

[group:party,nogroup:raid] show;[group:raid] show;hide

but if I later change the third argument to :SpawnHeader, this value will change as well. Would someone give me a hint at this?

[haste]

I thought I provided a way to retrieve the value, but it looks like I don't. Guess that one has slipped on my side .

Not a problem, l'll just set an upvalue for the visibily, use the custom rule for it and pass it along through the namespace. I'll post my progress later when I'm home.
