WoWInterface - slider variable saving and using

1. The getglobal function was deprecated years ago and should never be used by anyone for any reason. Use _G[value] instead of getglobal(value).

2. You use the GetValue method on your slider to get the current value:

Code:

local value = slider:GetValue()

3. To save anything between sessions, you first need to define a saved variable for your addon. Add something like this to your TOC file:

Code:

## SavedVariables: MyAddonSetting

4. Then, you need to initialize the variable with a reasonable default setting:

Code:

MyAddon.panel:RegisterEvent("PLAYER_LOGIN")

MyAddon.panel:SetScript("OnEvent", function(self)

        MyAddonSetting = MyAddonSetting or 65 -- Default to 65

end)

5. If you are only saving one setting, you can just use the variable directly:

Code:

## SavedVariables: MyAddonSliderValue

Code:

slider:SetScript("OnValueChanged", function(self)

        local value = self:GetValue()

        -- Save the value to your saved variable:

        MyAddonSetting = value

        -- Do whatever you want with the value here.

end)

6. If you want to save more than one setting, you should use a table:

Code:

## SavedVariables: MyAddonSettings

Code:

MyAddon.panel:RegisterEvent("PLAYER_LOGIN")

MyAddon.panel:SetScript("OnEvent", function(self)

        MyAddonSettings = MyAddonSetting or {

                slidervalue = 65,

                othervalue = 12,

                somevalue = "some string",

        }

end)



slider:SetScript("OnValueChanged", function(self)

        -- Get the slider's current value:

        local value = self:GetValue()



        -- Save the value to your saved variable:

        MyAddonSettings.slidervalue = value



        -- Do whatever you want with the value here.

end)

7. You should also add a refresh function to your options panel to set the slider's value based on the saved setting:

Code:

MyAddon.panel.refresh = function()

        slider:SetValue(MyAddonSettings.slidervalue)

end
