local btn = CreateFrame("Button", addonName.."MovingButton", UIParent, "UIPanelButtonTemplate")
btn:SetPoint("CENTER")
btn:SetSize(100, 40)
btn:SetText("Click me")
btn:SetScript("OnClick", function(self, button, ...)
btn:SetMovable(true)
btn:RegisterForDrag('LeftButton')
btn:SetUserPlaced(true) -- Only works if the frame is created before the PLAYER_LOGIN event
btn:SetScript('OnDragStart', btn.StartMoving)
btn:SetScript('OnDragStop', btn.StopMovingOrSizing)
    if (button == "RightButton" and btn:IsVisible()) then
        btn:Hide()
    end
 
    updateData()
    updateList()
    f:Show()
end)
btn:RegisterForClicks("AnyUp")
