範例

-- needs the dependency UI.condition_position.constructor
local pad = addon:AcquireConditionWidget("RM-ConditionPositionPad", UI.condition_position.constructor)
pad:SetCallback("OnOffsetChanged", function(_, _, dx, dy, center, amount)
    if center then value.x = 0 else value.x = (value.x or 0) + dx * amount end
end)
parent:AddChild(pad)

原始碼

UI/condition_position.lua，第 23 行。在遊戲中為唯讀；「複製」會產生一份可編輯的複本。

UI.condition_position.constructor()

    local w={type='RM-ConditionPositionPad',disabled=false}
    local frame=CreateFrame('Frame',nil,UIParent);w.frame=frame
    local pad=addon:CreateWorkbenchPositionPad(frame);w.pad=pad;pad:SetPoint('TOPLEFT')
    local clicks={}
    for name,button in pairs(pad.buttons) do clicks[name]=button:GetScript('OnClick') end
    function w:SetDisabled(value)
        self.disabled=value==true
        for _,button in pairs(pad.buttons) do if self.disabled then button:Disable() else button:Enable() end end
    end
    function w:OnAcquire()
        self:SetWidth(48);self:SetHeight(48);self:SetDisabled(false)
        local lease=self.rmLease
        local function live() return w.rmActive and w.rmLease==lease and not w.disabled and not w:IsReleasing() end
        pad:Bind(function(dx,dy,center,amount) w:Fire('OnOffsetChanged',dx,dy,center,amount) end,live,false)
        for name,button in pairs(pad.buttons) do
            local click=clicks[name]
            addon:SetUIScript(button,'OnClick',function(...) if live() then return click(...) end end)
