Super class

Background

Radio class generates radio button gadgets. They do the same job as cycle gadgets and eat up more window space, maybe that's the reason why so few of them can be found in existing applications.

Attributes

Attribute	Version	ISG	Type
MUIA_Radio_Active	V4	ISG	LONG
MUIA_Radio_Entries	V4	I..	STRPTR *

MUIA_Radio_Active

NAME

MUIA_Radio_Active -- V4 [ISG], LONG, 0x80429b41

FUNCTION

This attributes defines the number of the active entry in the radio gadget. Valid range is from 0 for the first entry to NumEntries-1 for the last.

Setting MUIA_Radio_Active causes the gadget to be updated. On the other hand, when the user plays around with the gadget, MUIA_Radio_Active will always reflects the current state.

EXAMPLE

set(radioobj, MUIA_Radio_Active, 3);

MUIA_Radio_Entries

NAME

MUIA_Radio_Entries -- V4 [I..], STRPTR *, 0x8042b6a1

FUNCTION

Here you can define what entries shall be displayed in your radio gadget. You must supply a pointer to a string array, containing one entry for each item and terminated with a NULL.

Remember that radio gadget entries may contain any text formatting code such as bold, italic or underlined characters.

By default, MUI will place the entries vertically below each other. But since Radio class is a subclass of Group class, you can use group layout attributes to adjust the layout to your needs, e.g. MUIA_Group_Horiz, TRUE for a horizontal radio button row or even MUIA_Group_Rows/Columns for a more fancy layout.

If you use these layout features, keep in mind that Radio class creates exactly one child object for each entry.

EXAMPLE

static const char *RA_GroupTitleColor[] =
{
  "normal",
  "highlight",
  "3-dimensional",
  NULL
};

CY_Title = RadioObject,
  MUIA_Radio_Entries, RA_GroupTitleColor,
  End;
