Stacks API

Slider — slider

Overview

• Type:slider
• Output Value:number

A slider for choosing from a range of numbers.

A slider always has a minimum and maximum value (defaults to 0 - 20). Tick marks can be displayed to help the user find specific values. The output value can be either an integer (if rounding is enabled) or a float.

Available: Stacks API v3

Minimum

• Key:min
• Type:number
• Default Value:0

Maximum

• Key:max
• Type:number
• Default Value:20

Rounding

• Key:rounding
• Type:Boolean
• Default Value:true

If rounding is enabled then the returned values will be integers. When disabled returned values will be floating point. Rounding is enabled by default

Note: because rounding is enabled by default, you must include this key and set it to False in order to disable rounding.

Ticks

• Key:ticks
• Type:number
• Default Value:0

Units

• Key:units
• Type:string
• Default Value:No units are displayed.

Default Value

• Key:default
• Type:string
• Default Value:The first menu item.

When the stack is placed onto the page the default value will be used. If no default is provided, 0 will be used.

Clear Value

• Key:clearValue
• Type:string
• Default Value:""

ID

• Key:id
• Type:string
• Required

The ID for this control. This ID must be unique within this stack. The ID is used to refer to control's property. IDs should be alpha-numeric (dashes and underscores are allowed), but should not contain special characters.

Title

• Key:title
• Type:string
• Default Value:"Untitled"
• Required

The title displayed next to the control. Long titles will be trancated, so keep it short.

Enable

• Key:enable
• Type:dictionary
• Default Value:enabled

Hide or show the control based on the value of another property.

Enables allow a stack to show only the controls needed by the user to achieve a specific task.

The enable dictionary defines the ID of another control and the value that other control must equal. When the other control's value is not equal to the provided value, this control is hidden.

Enable Dictionary

• id (string) — the ID of another control on which this control (Popup Menu) should depend.
• value (any type) — when the value of the other control is equal to this value, this control is displayed, otherwise it is hidden.

Warning: creating infinite loops in enable dependencies has undefined behavior but will likely result in a crash.

Tool Tip

• Key:toolTip
• Type:string
• Default Value:No tooltip is displayed.

The tooltip value is used to display hints for the user on the use of each control. If the function of the control is obvious, then a tooltip should be avoided. Simply re-displaying redundant information like the title has no value to the user.
