API GetCursorPosition

Returns the cursor's position on the screen. x, y = GetCursorPosition

Returns

 * x : Number - x coordinate unaffected by UI scale; 0 at the left edge of the screen.
 * y : Number - y coordinate unaffected by UI scale; 0 at the bottom edge of the screen.

Details
local uiScale, x, y = UIParent:GetEffectiveScale, GetCursorPosition local tex = UIParent:CreateTexture tex:SetTexture(1,1,1) tex:SetSize(4,4) tex:SetPoint("CENTER", nil, "BOTTOMLEFT", x / uiScale, y / uiScale)
 * Returns scale-independent coordinates similar to Cursor:GetCenter if 'Cursor' was a valid frame not affected by scaling.
 * Assuming UIParent spans the entire screen, you can convert these coordinates to UIParent offsets by dividing by its effective scale. The following snippet positions a small texture at the cursor's location.
