BBjRadioButton	addRadioButton(int ID, int x,int y, int width, int height, string title, string flags)
BBjRadioButton	addRadioButton(int ID, String title)
BBjRadioButton	addRadioButton(int ID, String title, String flags)
BBjRadioButton	addRadioButton(String title)
BBjRadioButton	addRadioButton(String title, String flags)

CSS

The visual appearance of BUI controls is defined using CSS (cascading style sheets) rules. Easily change the default colors, border, and other settings by customizing these rules, all without changing any application code. See CSS API for a high-level overview of BUI CSS.

The BBjRadioButton is implemented as an <input type="radio"> element with an associated label. It defines the following style names:

.BBjRadioButton

.BBjRadioButton.bbj-checked

.BBjRadioButton.bbj-disabled

.BBjRadioButton.bbj-focused

.BBjRadioButton.bbj-readonly

HTML checkbox and radiobutton elements are notoriously difficult to style.

Remarks

By default, radiobuttons are not automatically selected when they gain focus programmatically or by user keyboard operation (TAB/SHIFT+TAB or LEFT, RIGHT, UP, DOWN arrows within a keyboard navigation group). In BBj 16 and higher, setting the RADIOBUTTON_SELECT !COMPAT setting to TRUE causes radiobuttons to be selected when they gain focus for any reason.
