Checkbox — checkbox

Available: Stacks API v8

A checkbox for enabling or selecting from two options.

Although a checkbox would seem to return a boolean value, for historical reasons a checkbox control is able to return any value type. This means, by using the True Value and False Value properties a checkbox can return the string “Jedi” if checked and the value “Sith” when unchecked, or integers, floats, or booleans.

Radio Mode

Checkboxes arrays can be used where only one of the group is allowed to be checked at a time. To use checkboxes in this mode use one of the array types (see below) and enable the Radio property.

New

Checkbox Array

Checkboxes can be used in arrays. Each has its own subtitle, trueValue, falseValue, and default, all other values are shared.

NB: checkbox-3 and trueValue/falseValue arrays requires Stacks API v8 (Stacks v3.1+), 2 & 4 require v7 (Stacks v3.0+), single control requires v1.

Checkbox types are:


Radio Buttons

Radio buttons will allow only one button in the group to be pushed.


True Value

When the checkbox is checked this value will be used in replacement templates. In arrays, this may be an arrof of strings.


False Value

When the checkbox is unchecked this value will be used in replacement templates. In arrays, this may be an arrof of strings.


Default Value

When this stack is placed on a page the default value will be used. The default value should be either the true or false values.


ID

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

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




Enable

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 Operations

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

NB: macOS does not specify the wildcard characters available or how they function. * and ? clearly work as they do in a UNIX shell. you’ll just have to guess at the rest.




Tool Tip

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.




Subtitles

Subtitles are displayed under the control. Subtitles are unique for each item in a control array. You should provide one for each item in the control array. In the plist the subtitles should be an array of Subtitle strings. Note that some controls have very little space, so only very short subtitles can be used.




Scope

New

The scope of a property can be set to bind to the page instead of each stack. Binding a property to the page-scope means that the values set by this control will be shared between all stack-instances on the page.




Inheritance

New

Inheritance allows one stack to pull in the controls and properties of another stack. All of the controls from the specified stack are pulled in to the current stack. The inherited controls will be ordered as if they were they were first in the plist customItems array. The value should be the ID of the stack to inherit from.
