mwseMCMSlider⚓︎

A slider for setting numerical values.

This type inherits the following: mwseMCMSetting, mwseMCMComponent

Properties⚓︎

callback⚓︎

The custom function called when the player interacts with this Setting.

Returns:

childIndent⚓︎

The left padding size in pixels. Used on all the child components.

Returns:

  • result (integer, nil)

childSpacing⚓︎

The bottom border size in pixels. Used on all the child components.

Returns:

  • result (integer, nil)

class⚓︎

Every MCM component has a unique string indentifier specific to that component. These strings are the filename of the file implementing a component. These are found in core\\mcm\\components.

Returns:

  • result (string)

componentType⚓︎

The type of this component.

Returns:

  • result ("Setting")

config⚓︎

The config to use when creating a mwseMCMTableVariable for this Setting. If provided, it will override the config stored in parentComponent. Otherwise, the value in parentComponent will be used.

Returns:

  • result (table, nil)

configKey⚓︎

The configKey used to create a new mwseMCMTableVariable. If this is provided, along with a config (which may be inherited from the parentComponent), then a new mwseMCMTableVariable variable will be created for this setting.

Returns:

  • result (string, number, nil)

converter⚓︎

A converter to use for this component's variable.

Returns:

  • result ((fun(newValue: unknown): unknown), nil)

createContentsContainer⚓︎

This method creates the contents of a component. Not every component implements this method.

Returns:

decimalPlaces⚓︎

The number of decimal places of precision. Must be a nonnegative integer. Default is 0.

Returns:

  • result (integer)

defaultConfig⚓︎

The defaultConfig to use when creating a mwseMCMTableVariable for this Setting. If provided, it will override the defaultConfig stored in parentComponent. Otherwise, the value in parentComponent will be used.

Returns:

  • result (table, nil)

defaultSetting⚓︎

If defaultSetting wasn't passed in the variable table, can be passed here. The new variable will be initialized to this value. If not provided, then the value in defaultConfig will be used, if possible.

Returns:

  • result (unknown, nil)

description⚓︎

If in a Sidebar Page, the description will be shown on mouseover.

Returns:

  • result (string, nil)

Methods⚓︎

checkDisabled⚓︎

Returns true if the component should be disabled.

Componets with a variable:

  • True if the Component's variable has inGameOnly field set to true, and the game is on the main menu. For components with multiple subcomponent (Category), the check is done for each subcomponent.

Components without a variable:

  • True if the Component's inGameOnly field is set to true, and the game is on the main menu.
local result = myObject:checkDisabled()

Returns:

  • result (boolean)

convertToLabelValue⚓︎

This function specifies how values stored in the variable field should correspond to values displayed in the slider label. The default behavior is to consistently format decimal places (i.e., if decimalPlaces == 2, make sure two decimal places are shown.) This can be overwritten in the createNewSlider method, allowing for custom formatting of variable values.

local labelValue = myObject:convertToLabelValue(variableValue)

Parameters:

  • variableValue (number)

Returns:

  • labelValue (number, string)
Example: DistanceSlider

The following example shows how the convertToLabelValue parameter can be used to create a slider for a config setting that handles distances. The config setting will be stored using game units, but the displayed value will be in real-world units. Recall that 1 game unit corresponds to 22.1 feet, and 1 foot is 0.3048 meters.

--- @type tes3uiElement, table
local myPage, myConfig
mwse.mcm.createSlider{
    parent = myPage,
    label = "My distance slider",
    variable = mwse.mcm.createTableVariable{ id = "distance", table = myConfig },
    convertToLabelValue = function(self, variableValue)
        local feet = variableValue / 22.1
        local meters = 0.3048 * feet
        if self.decimalPlaces == 0 then
            return string.format("%i ft (%.2f m)", feet, meters)
        end
        return string.format(
            -- if `decimalPlaces == 1, then this string will simplify to
            -- "%.1f ft (%.3f m)"
            string.format("%%.%uf ft (%%.%uf m)", self.decimalPlaces, self.decimalPlaces + 2),
            feet, meters
        )
    end,

    max = 22.1 * 10,    -- max is 10 feet
    step = 22.1,        -- increment by 1 foot
    jump = 22.1 * 5,
}
Example: SkillSlider

Here is an (admittedly less practical) example to help highlight the different ways convertToLabelValue can be used. In this example, it will be used to create a slider that stores a tes3.skill constant in the config, and then displays the name of the corresponding skill.

--- @type tes3uiElement, table
local myPage, myConfig
mwse.mcm.createSlider{
    parent = myPage,
    label = "My skill slider",
    variable = mwse.mcm.createTableVariable{ id = "skillId", table = myConfig },
    convertToLabelValue = function(self, variableValue)
        local skillName = tes3.getSkillName(math.round(variableValue))
        if skillName then
            return skillName
        end
        return "N/A"
    end,

    max = 26 -- there are 27 skills and indexing starts at 0
}

convertToVariableValue⚓︎

This function specifies how values stored in the slider widget should correspond to values stored in the variable field.

This conversion is necessary because the widget can only store whole numbers, and the range of allowed values must start at 0, while the corresponding variable can store decimal numbers and the range can start at any number. In the vast majority of use-cases, you do not need to call this method directly.

local variableValue = myObject:convertToVariableValue(widgetValue)

Parameters:

  • widgetValue (number)

Returns:

  • variableValue (number)

convertToWidgetValue⚓︎

This method specifies how values stored in the variable field should correspond to values stored in the slider UI widget.

This conversion is necessary because the widget can only store whole numbers, and the range of allowed values must start at 0, while the corresponding variable can store decimal numbers and the range can start at any number. In the vast majority of use-cases, you do not need to call this method directly.

local widgetValue = myObject:convertToWidgetValue(variableValue)

Parameters:

  • variableValue (number)

Returns:

  • widgetValue (number)

create⚓︎

This method creates the UI elements specific to Slider.

myObject:createContentsContainer(parentBlock)

Parameters:

createInnerContainer⚓︎

Creates component's innerContainer UI element inside given parentBlock, and stores it in the self.elements.innerContainer. The innerContainer will add self.indent additional padding on the left if the component has a label.

myObject:createInnerContainer(parentBlock)

Parameters:

createLabel⚓︎

Creates component's label UI element.

First, it calls self:createLabelBlock and creates the label element inside new labelBlock. Stores both new UI elements in the self.elements and self.mouseOvers.

myObject:createLabel(parentBlock)

Parameters:

createLabelBlock⚓︎

Creates component's labelBlock UI element inside given parentBlock, and stores it in the self.elements.labelBlock and self.mouseOvers.

myObject:createOuterContainer(parentBlock)

Parameters:

disable⚓︎

This method disables the component's UI elements. That includes: changing the color of the UI elements to the tes3.palette.disabledColor and setting button widget state to tes3.uiState.disabled.

myObject:disable()

enable⚓︎

Enables the component's UI elements. That includes: changing the color of the UI elements to the tes3.palette.normalColor and registering handlers for tes3.uiEvent.mouseClick for buttons.

myObject:enable()

getMouseOverText⚓︎

Retrieves the text that this setting should display in any related mouseOverInfos. This method currently utilized to display this component's description whenever the component is in a SideBarPage. If this Setting has showDefaultSetting == true, then this method will also include the current defaultSetting.

Primarily intended for internal use.
