radiogroup

Radio button or check box

Description

Provides a user interface for option selection. There are two modes of operation: radio button and checkbox.

Examples

Radio buttons allow a single selection, and multiple selection check boxes can control several gates

Discussion

The radiogroup object has two modes of operation: radio button and check box. In radio button mode, the radiogroup object provides a user-definable number of buttons in a group, only one of which may be selected at a time. In check box mode, the indicators in the radiogroup object function as a set of on/off indicators. Check box mode also supports a way to have the checkboxes act as indicators for the bit pattern of a binary representation of an integer (see the flagmode message).

Note: radiogroup can be re-sized horizontally so it will extend under comment boxes placed to the right of the buttons or boxes. this way, clicking on the text to the right of the button will also set the button selection or box state.

Arguments

None.

Attributes

activecolor [4 floats]

Sets the color for the active radiobuttons/checkboxes in RGBA format.

bgcolor [4 floats]

Sets the background color for the object in RGBA format.

Off Color

enabled [atom]

Enables/disables buttons. The word enabled , followed by followed by a list of zeroes and ones whose length is the same as the number of buttons or boxes, will disable (0) or enable (1) the item in the list position that corresponds to the button or box (e.g., enableitem 1 1 1 0 will disable only the fourth button or box).

flagmode [int] (default: 0)

Sets the flag mode of operation for the radiogroup object. In this mode, each check box corresponds to one bit in an integer value (i.e., the first radio button or checkbox corresponds to the ones bit, the second button or checkbox to the twos bit, the third button or checkbox to the fours bit, etc.). The message flagmode 0 disables this mode (default).

Parameter Attributes

Order

Typeint

Sets the order of recall of this parameter. Lower numbers are recalled first. The order of recall of parameters with the same order number is undefined.

Parameter Mode Enable

Typeint

Parameter Mode Enable (not available from Parameters window)

Link to Scripting Name

Typeint

When checked, the Scripting Name is linked to the Long Name attribute.

Long Name

Typesymbol

The long name of the parameter. This name must be unique per patcher hierarchy.

Short Name

Typesymbol

Sets the short name for the object's visual display. The maximum length varies according to letter width, but is generally in a range of 5 to 7 characters.

Type

Typeint

Specifies the data type. The data types used in Max for Live are:

Float
Int
Enum (enumerated list)
Blob

Note: By convention, the Live application uses floating point numbers for its calculations; the native integer representation is limited to a range of 0-255 (similar to the char data type used in Jitter). When working with Live UI objects whose integer values are likely to be outside of the 0-255 range, the Type attribute should be set to Float, and the Unit Style attribute should be set to Int.

Range/Enum

Typelist

When used with an integer or floating point data type, this field is used to specify the minimum and maximum values of the parameter.
When used with an enumerated list (Enum) data type, this field contains a space-delimited list of the enumerated values (if list items contain a space or special characters, the name should be enclosed in double quotes).

Modulation Mode

Typeint

Sets the Modulation Mode used by the Live application. The modulation modes are:

None
Unipolar
Bipolar
Additive
Absolute

Modulation Range

Typelist

This parameter is only used with the Absolute modulation mode. It specifies defines the range of values used.

Initial Enable

Typeint

When checked (set to 1), the UI object can store an initialization value. The value is set using the Initial attribute (see below).

Initial

Typelist

Sets the initial value to be stored and used when the Initial Enable attribute is checked.

Unit Style

Typeint

Sets the unit style to be used when displaying values. The unit style values are: Int: displays integer values
Float: displays floating point values
Time: displays time values in milliseconds (ms)
Hertz: displays frequency values (Hz/kHz).
deciBel: displays loudness (dB)
%: Percentage
Pan: displays Left and Right values
Semitones: displays steps (st)
MIDI: displays pitch corresponding to the MIDI note number
Custom: displays custom data type
Native: defaults to floating point values

Custom Units

Typesymbol

Sets the units to be used with the 'Custom' unit style (see "Unit Style", above). Custom unit strings may be simple symbols (e.g. "Harmonic(s)"), in which case the parameter's value will be displayed in its 'Native' display mode, followed by the symbol (e.g. "12 Harmonic(s)" for an Int-typed parameter or "12.54 Harmonic(s)" for a Float-typed parameter). For additional control over the numerical component displayed, a sprintf-style string may be used (e.g. "%0.2f Bogon(s)", which would display a value such as ".87 Bogons").

Exponent

Typefloat

When set to a value other than 1., the parameter's input and output values will be exponentially scaled according to the factor entered in this column.

Steps

Typeint

The number of steps available between the minimum and maximum values of a parameter. For instance, if the parameter has a range from 0.-64., with Steps set to 4, the user can only set the parameter to 0, 21.33, 42.66 and 64.

Parameter Visibility

Typeint

For automatable parameters (Int, Float, Enum), 'Stored Only' disables automation, although parameter values are stored in presets. 'Hidden' causes the parameter's value to be ignored when storing and recalling data. Non-automatable parameters (Blob) are 'Stored Only' by default, and can be set to 'Hidden', if desired.

Update Limit (ms)

Typeint

Speed limits values triggered by automation.

Defer Automation Output

Typeint

Defers values triggered by automation.

Messages

bang

In radio button mode: A bang outputs the currently selected radio button number.

In check box mode: A bang outputs a list of zeros and ones representing the on/off state of the check boxes.

In flag mode: A bang send the integer that corresponds to the bit pattern of the currently checked boxes (i.e., if boxes one, two, and three are checked, a bang will output a value of 7 )out the radiogroup object's output.

int

Arguments

selection [int]
In radio button mode: An integer sets the radio button selection and outputs the input value. Numbering starts with 0, and a negative number indicates that no buttons will be selected.

In flag mode: An integer value received in the radiogroup object's inlet will set the buttons or checkboxes to reflect the bit pattern of the integer value (i.e., a value of 19 will select boxes one, two, and five, corresponding to the binary value 10011 ) and send the integer value out the radiogroup object's output.

list

Arguments

states [list]
In check box mode: list of zeros and ones sets the check box states and causes output of the input list. If you have specified check box mode and have the flag mode set using the flagmode 1 message, a list of zeros and ones sets the check box states and causes output of the input list.

enableitem

Arguments

indices [list]
In radio button and check box modes: The word enableitem , followed by followed by a number or list of numbers, will enable the items whose numbers are indicated if they have been disabled with the disableitem message.

disableitem

Arguments

indices [list]
In radio button and check box modes: disable the items whose numbers are indicated (they will be drawn in grey and will not respond to clicks, although they will still respond to set messages, ints or lists).

(mouse)

In radio button mode, clicking on a radio button will set the radio button selection and output the corresponding button number (numbering starts from zero). In check box mode, clicking on a check box will change its state (from one to zero or from zero to one) and output a list of zeros and ones corresponding to the on/off state of the boxes. if the entire group of buttons/boxes is inactive (grayed out) it will not respond to clicks. if an individual item is disabled (grayed out) it will not respond to clicks, although active items in the group will still respond to clicks as usual. The Flag Mode variation on the check box mode has check boxes that correspond to bit positions for a binary value (i.e. the first checkbox corresponds to the 1s, the second to 2s, the third to 4s, etc.) Clicking on a check box will select or deselect the check box and output the integer value which corresponds to the bit pattern.

set

Arguments

selection [list]
In radio button mode: The word set , followed by a number, sets the currently selected radio button without triggering any output.

In check box mode: The word set , followed by a list of zeros and ones, sets the check box states without triggering any output.

If you are using check box mode and are also using Flag Mode, a number will set the state of the first 32 checkboxes in a pattern which corresponds to the bit pattern of the number without triggering output (see the flagmode section for more information).

Output

int

In radio button mode: Clicking on a radio button outputs an int corresponding to the radio button selected. Numbering begins with 0.

In flag mode: Clicking on a check box outputs an int corresponding to the bit pattern represented by the checked boxes (i.e., if boxes one, two, and three are checked, a bang will output a value of 7 ).

list

In check box mode: A bang will output a list of zeros and one which indicate the on/off state of the group of check boxes.
