Changing a box in combat

[zork]

I have a frame.

I want to resize or repoint it while being in combat.

Any idea on how to do it?

The problem is I need to to it in an OnClick script. I cannot drag the size manually.

*edit*

I fixed my problem. I'm now using:

--frame
  local hoverFrame = CF("BUTTON", addon.."HoverFrame", manager, "SecureHandlerClickTemplate")
  hoverFrame:SetAttribute("_onclick", [=[
    local ref = self:GetFrameRef("manager")
    if not ref:GetAttribute("state") then
      ref:SetAttribute("state","closed")
    end
    local state = ref:GetAttribute("state")
    if state == "closed" then
      ref:SetAlpha(1)
      ref:SetWidth(275)
      ref:SetAttribute("state","open")
    else
      ref:SetAlpha(0.4)
      ref:SetWidth(200)
      ref:SetAttribute("state","closed")
    end
  ]=])
  hoverFrame:SetFrameRef("manager", manager)

Are you talking about a protected frame?

Do you want it to be resized by the user or automatically?

[zork]

No. That is a frame I made on my own. Using SecureHandlerClickTemplate did what I needed though.

Ok...I'm still on this topic since I want to get into secure frames a bit more.

I have a panel frame. Ontop of that panel frame is a clickframe that will change the size/alpha of the panel frame. This works already thanks to the "SecureHandlerClickTemplate" posted above.

Now I want to take it a step further. I want to hide the frame if I'm not in a group and I want to show it if I am. Of course this should happen securely.

My current question is: How would you do sth like this?

My current guess is the following code. Basically I'm inheriting "SecureHandlerAttributeTemplate" on the frame. Next I'm registern "PARTY_MERMBERS_CHANGED" event. Once that fires I change an attribute. The attribute change triggers "_onattributechanged" and I use it to Show/Hide the frame. Is that the way to do it?

--manager onevent
  local function ManagerOnEvent(self, event)
    if GetNumGroupMembers() > 0 then
      self:SetAttribute("in-group",1)      
    else
      self:SetAttribute("in-group",0)      
    end
  end
 
  --create manager frame
  local manager = CreateFrame("Frame", addon, UIP, "SecureHandlerAttributeTemplate")
  
  --manager onattributechanged
  manager:SetAttribute("_onattributechanged", [=[
    --self, name, value
    if name ~= "in-group" then return end
    if value == 1 and self:IsShown() then return end
    if value == 1 then
      self:Show()
    else
      self:Hide()
    end
  ]=])
  manager:RegisterEvent("PARTY_LOGIN")  
  manager:RegisterEvent("PARTY_MEMBERS_CHANGED")
  manager:SetScript("OnEvent", ManagerOnEvent)

The event you want is GROUP_ROSTER_UPDATE, then do the usual if IsInGroup() then ... in your event handler.

I decided to go with this for now. SetAttribute is blocked in combat.

local manager = CreateFrame("Frame", addon, UIP, "SecureHandlerStateTemplate")
RegisterStateDriver(manager, "visibility", "[group:party][group:raid] show; hide")

You can use just [group] as a synonym for [group:raid][group:party]. I believe the world markers are only available to party and raid leaders and assistants, don't know if you'd get a warning when trying to use them without the proper permissions.
