Lua error when retrieving protected frame width?

[Zax]

Hello,

I use this code to retrieve infos of frames under the mouse cursor:

function frameSpecs()
    local function getFrameInfos(f)
        local tmp = f:GetName()
        if (tmp ~= nil) then
            return tmp.."--- "..f:GetObjectType().." "..floor(f:GetWidth()).." x "..floor(f:GetHeight()).." px --- alpha = "..f:GetAlpha().." ("..f:GetEffectiveAlpha()..")"
        else
            return nil
        end
    end
    
    local thisFrame = EnumerateFrames()
    while thisFrame do
        if (MouseIsOver(thisFrame) and thisFrame:IsVisible()) then
            local tmp = getFrameInfos(thisFrame)
            if (tmp ~= nil) then print(getFrameInfos(thisFrame)) end
        end
        thisFrame = EnumerateFrames(thisFrame)
    end
end

It works fine but raises a lua error if the frame is protected when retrieving its width.

Is it normal for such a getter function to raise an error?
Is there a way for this function to print an error string instead of generating a big lua error?

This link include 2 possible functions you could check for potential issues before trying ..

Namely IsProtected and IsForbidden.

Thanks.

Even if I use IsProtected() or IsForbidden(), the script still raises a lua error but I think the error comes from MouseIsOver().
The script worked fine on all frames with WoW 10.x, so I guess it is now incompatible with WoW 11.

Even a shortened version like the following no longer works:

local thisFrame = EnumerateFrames()
    while thisFrame do
        if (MouseIsOver(thisFrame)) then
              print(thisFrame:GetName())
        end
        thisFrame = EnumerateFrames(thisFrame)
    end

I wonder if it's linked to the mouse changes

But can't see any other complaints about it, despite using it in recent months.

You could the function that function calls in case that makes a difference

function MouseIsOver(region, topOffset, bottomOffset, leftOffset, rightOffset)
    return region:IsMouseOver(topOffset, bottomOffset, leftOffset, rightOffset);
end

Maybe they don't want you to use their function but you can use the api function. fingers crossed

function MouseIsOver(region, topOffset, bottomOffset, leftOffset, rightOffset)
    return region:IsMouseOver(topOffset, bottomOffset, leftOffset, rightOffset);
end

Thanks anyway.
