Scrollframes:SetPoint and clipping
In this code a scrollframe is moved to a different position. Doing that naively, results in the clipping not correctly updating. Hiding the scrollframe before setting the new position and then reshowing updates the clipping.
That is, I would expect spinner1 and spinner2 to behave identically.
Code:
local function createFrame()
local spinner = CreateFrame('Frame', nil, parent)
spinner:SetSize(64, 64)
-- ScrollFrame is the top right quadrant of spinner
local scrollframe = CreateFrame('ScrollFrame', nil, spinner)
scrollframe:SetPoint('BOTTOMLEFT', spinner, 'CENTER')
scrollframe:SetPoint('TOPRIGHT')
spinner.scrollframe = scrollframe
local scrollchild = CreateFrame('frame', nil, scrollframe)
scrollframe:SetScrollChild(scrollchild)
scrollchild:SetAllPoints(scrollframe)
-- Clipped by scrollframe
local wedge = scrollchild:CreateTexture()
wedge:SetAllPoints(spinner)
spinner.wedge = wedge;
return spinner;
end
local spinner1 = createFrame();
spinner1:SetPoint('BOTTOMRIGHT', UIParent, 'CENTER', -2, 2);
spinner1.wedge:SetTexture('interface/icons/inv_mushroom_11')
local spinner2 = createFrame();
spinner2:SetPoint('BOTTOMLEFT', UIParent, 'CENTER', 2, 2);
spinner2.wedge:SetTexture(236595)
C_Timer.After(3, function()
-- Move the scroll frames to the top left quadrant
spinner1.scrollframe:ClearAllPoints();
spinner1.scrollframe:SetPoint('BOTTOMRIGHT', spinner1, 'CENTER');
spinner1.scrollframe:SetPoint('TOPLEFT');
spinner2.scrollframe:Hide();
spinner2.scrollframe:ClearAllPoints();
spinner2.scrollframe:SetPoint('BOTTOMRIGHT', spinner2, 'CENTER');
spinner2.scrollframe:SetPoint('TOPLEFT');
spinner2.scrollframe:Show();
end)
